What Is Bitcoin, and How Does it Work?

Technical: The Path to Taproot Activation

Taproot! Everybody wants to have it, somebody wants to make it, nobody knows how to get it!
(If you are asking why everybody wants it, see: Technical: Taproot: Why Activate?)
(Pedants: I mostly elide over lockin times)
Briefly, Taproot is that neat new thing that gets us:
So yes, let's activate taproot!

The SegWit Wars

The biggest problem with activating Taproot is PTSD from the previous softfork, SegWit. Pieter Wuille, one of the authors of the current Taproot proposal, has consistently held the position that he will not discuss activation, and will accept whatever activation process is imposed on Taproot. Other developers have expressed similar opinions.
So what happened with SegWit activation that was so traumatic? SegWit used the BIP9 activation method. Let's dive into BIP9!

BIP9 Miner-Activated Soft Fork

Basically, BIP9 has a bunch of parameters:
Now there are other parameters (name, starttime) but they are not anywhere near as important as the above two.
A number that is not a parameter, is 95%. Basically, activation of a BIP9 softfork is considered as actually succeeding if at least 95% of blocks in the last 2 weeks had the specified bit in the nVersion set. If less than 95% had this bit set before the timeout, then the upgrade fails and never goes into the network. This is not a parameter: it is a constant defined by BIP9, and developers using BIP9 activation cannot change this.
So, first some simple questions and their answers:

The Great Battles of the SegWit Wars

SegWit not only fixed transaction malleability, it also created a practical softforkable blocksize increase that also rebalanced weights so that the cost of spending a UTXO is about the same as the cost of creating UTXOs (and spending UTXOs is "better" since it limits the size of the UTXO set that every fullnode has to maintain).
So SegWit was written, the activation was decided to be BIP9, and then.... miner signalling stalled at below 75%.
Thus were the Great SegWit Wars started.

BIP9 Feature Hostage

If you are a miner with at least 5% global hashpower, you can hold a BIP9-activated softfork hostage.
You might even secretly want the softfork to actually push through. But you might want to extract concession from the users and the developers. Like removing the halvening. Or raising or even removing the block size caps (which helps larger miners more than smaller miners, making it easier to become a bigger fish that eats all the smaller fishes). Or whatever.
With BIP9, you can hold the softfork hostage. You just hold out and refuse to signal. You tell everyone you will signal, if and only if certain concessions are given to you.
This ability by miners to hold a feature hostage was enabled because of the miner-exit allowed by the timeout on BIP9. Prior to that, miners were considered little more than expendable security guards, paid for the risk they take to secure the network, but not special in the grand scheme of Bitcoin.

Covert ASICBoost

ASICBoost was a novel way of optimizing SHA256 mining, by taking advantage of the structure of the 80-byte header that is hashed in order to perform proof-of-work. The details of ASICBoost are out-of-scope here but you can read about it elsewhere
Here is a short summary of the two types of ASICBoost, relevant to the activation discussion.
Now, "overt" means "obvious", while "covert" means hidden. Overt ASICBoost is obvious because nVersion bits that are not currently in use for BIP9 activations are usually 0 by default, so setting those bits to 1 makes it obvious that you are doing something weird (namely, Overt ASICBoost). Covert ASICBoost is non-obvious because the order of transactions in a block are up to the miner anyway, so the miner rearranging the transactions in order to get lower power consumption is not going to be detected.
Unfortunately, while Overt ASICBoost was compatible with SegWit, Covert ASICBoost was not. This is because, pre-SegWit, only the block header Merkle tree committed to the transaction ordering. However, with SegWit, another Merkle tree exists, which commits to transaction ordering as well. Covert ASICBoost would require more computation to manipulate two Merkle trees, obviating the power benefits of Covert ASICBoost anyway.
Now, miners want to use ASICBoost (indeed, about 60->70% of current miners probably use the Overt ASICBoost nowadays; if you have a Bitcoin fullnode running you will see the logs with lots of "60 of last 100 blocks had unexpected versions" which is exactly what you would see with the nVersion manipulation that Overt ASICBoost does). But remember: ASICBoost was, at around the time, a novel improvement. Not all miners had ASICBoost hardware. Those who did, did not want it known that they had ASICBoost hardware, and wanted to do Covert ASICBoost!
But Covert ASICBoost is incompatible with SegWit, because SegWit actually has two Merkle trees of transaction data, and Covert ASICBoost works by fudging around with transaction ordering in a block, and recomputing two Merkle Trees is more expensive than recomputing just one (and loses the ASICBoost advantage).
Of course, those miners that wanted Covert ASICBoost did not want to openly admit that they had ASICBoost hardware, they wanted to keep their advantage secret because miners are strongly competitive in a very tight market. And doing ASICBoost Covertly was just the ticket, but they could not work post-SegWit.
Fortunately, due to the BIP9 activation process, they could hold SegWit hostage while covertly taking advantage of Covert ASICBoost!

UASF: BIP148 and BIP8

When the incompatibility between Covert ASICBoost and SegWit was realized, still, activation of SegWit stalled, and miners were still not openly claiming that ASICBoost was related to non-activation of SegWit.
Eventually, a new proposal was created: BIP148. With this rule, 3 months before the end of the SegWit timeout, nodes would reject blocks that did not signal SegWit. Thus, 3 months before SegWit timeout, BIP148 would force activation of SegWit.
This proposal was not accepted by Bitcoin Core, due to the shortening of the timeout (it effectively times out 3 months before the initial SegWit timeout). Instead, a fork of Bitcoin Core was created which added the patch to comply with BIP148. This was claimed as a User Activated Soft Fork, UASF, since users could freely download the alternate fork rather than sticking with the developers of Bitcoin Core.
Now, BIP148 effectively is just a BIP9 activation, except at its (earlier) timeout, the new rules would be activated anyway (instead of the BIP9-mandated behavior that the upgrade is cancelled at the end of the timeout).
BIP148 was actually inspired by the BIP8 proposal (the link here is a historical version; BIP8 has been updated recently, precisely in preparation for Taproot activation). BIP8 is basically BIP9, but at the end of timeout, the softfork is activated anyway rather than cancelled.
This removed the ability of miners to hold the softfork hostage. At best, they can delay the activation, but not stop it entirely by holding out as in BIP9.
Of course, this implies risk that not all miners have upgraded before activation, leading to possible losses for SPV users, as well as again re-pressuring miners to signal activation, possibly without the miners actually upgrading their software to properly impose the new softfork rules.

BIP91, SegWit2X, and The Aftermath

BIP148 inspired countermeasures, possibly from the Covert ASiCBoost miners, possibly from concerned users who wanted to offer concessions to miners. To this day, the common name for BIP148 - UASF - remains an emotionally-charged rallying cry for parts of the Bitcoin community.
One of these was SegWit2X. This was brokered in a deal between some Bitcoin personalities at a conference in New York, and thus part of the so-called "New York Agreement" or NYA, another emotionally-charged acronym.
The text of the NYA was basically:
  1. Set up a new activation threshold at 80% signalled at bit 4 (vs bit 1 for SegWit).
    • When this 80% signalling was reached, miners would require that bit 1 for SegWit be signalled to achive the 95% activation needed for SegWit.
  2. If the bit 4 signalling reached 80%, increase the block weight limit from the SegWit 4000000 to the SegWit2X 8000000, 6 months after bit 1 activation.
The first item above was coded in BIP91.
Unfortunately, if you read the BIP91, independently of NYA, you might come to the conclusion that BIP91 was only about lowering the threshold to 80%. In particular, BIP91 never mentions anything about the second point above, it never mentions that bit 4 80% threshold would also signal for a later hardfork increase in weight limit.
Because of this, even though there are claims that NYA (SegWit2X) reached 80% dominance, a close reading of BIP91 shows that the 80% dominance was only for SegWit activation, without necessarily a later 2x capacity hardfork (SegWit2X).
This ambiguity of bit 4 (NYA says it includes a 2x capacity hardfork, BIP91 says it does not) has continued to be a thorn in blocksize debates later. Economically speaking, Bitcoin futures between SegWit and SegWit2X showed strong economic dominance in favor of SegWit (SegWit2X futures were traded at a fraction in value of SegWit futures: I personally made a tidy but small amount of money betting against SegWit2X in the futures market), so suggesting that NYA achieved 80% dominance even in mining is laughable, but the NYA text that ties bit 4 to SegWit2X still exists.
Historically, BIP91 triggered which caused SegWit to activate before the BIP148 shorter timeout. BIP148 proponents continue to hold this day that it was the BIP148 shorter timeout and no-compromises-activate-on-August-1 that made miners flock to BIP91 as a face-saving tactic that actually removed the second clause of NYA. NYA supporters keep pointing to the bit 4 text in the NYA and the historical activation of BIP91 as a failed promise by Bitcoin developers.

Taproot Activation Proposals

There are two primary proposals I can see for Taproot activation:
  1. BIP8.
  2. Modern Softfork Activation.
We have discussed BIP8: roughly, it has bit and timeout, if 95% of miners signal bit it activates, at the end of timeout it activates. (EDIT: BIP8 has had recent updates: at the end of timeout it can now activate or fail. For the most part, in the below text "BIP8", means BIP8-and-activate-at-timeout, and "BIP9" means BIP8-and-fail-at-timeout)
So let's take a look at Modern Softfork Activation!

Modern Softfork Activation

This is a more complex activation method, composed of BIP9 and BIP8 as supcomponents.
  1. First have a 12-month BIP9 (fail at timeout).
  2. If the above fails to activate, have a 6-month discussion period during which users and developers and miners discuss whether to continue to step 3.
  3. Have a 24-month BIP8 (activate at timeout).
The total above is 42 months, if you are counting: 3.5 years worst-case activation.
The logic here is that if there are no problems, BIP9 will work just fine anyway. And if there are problems, the 6-month period should weed it out. Finally, miners cannot hold the feature hostage since the 24-month BIP8 period will exist anyway.

PSA: Being Resilient to Upgrades

Software is very birttle.
Anyone who has been using software for a long time has experienced something like this:
  1. You hear a new version of your favorite software has a nice new feature.
  2. Excited, you install the new version.
  3. You find that the new version has subtle incompatibilities with your current workflow.
  4. You are sad and downgrade to the older version.
  5. You find out that the new version has changed your files in incompatible ways that the old version cannot work with anymore.
  6. You tearfully reinstall the newer version and figure out how to get your lost productivity now that you have to adapt to a new workflow
If you are a technically-competent user, you might codify your workflow into a bunch of programs. And then you upgrade one of the external pieces of software you are using, and find that it has a subtle incompatibility with your current workflow which is based on a bunch of simple programs you wrote yourself. And if those simple programs are used as the basis of some important production system, you hve just screwed up because you upgraded software on an important production system.
And well, one of the issues with new softfork activation is that if not enough people (users and miners) upgrade to the newest Bitcoin software, the security of the new softfork rules are at risk.
Upgrading software of any kind is always a risk, and the more software you build on top of the software-being-upgraded, the greater you risk your tower of software collapsing while you change its foundations.
So if you have some complex Bitcoin-manipulating system with Bitcoin somewhere at the foundations, consider running two Bitcoin nodes:
  1. One is a "stable-version" Bitcoin node. Once it has synced, set it up to connect=x.x.x.x to the second node below (so that your ISP bandwidth is only spent on the second node). Use this node to run all your software: it's a stable version that you don't change for long periods of time. Enable txiindex, disable pruning, whatever your software needs.
  2. The other is an "always-up-to-date" Bitcoin Node. Keep its stoarge down with pruning (initially sync it off the "stable-version" node). You can't use blocksonly if your "stable-version" node needs to send transactions, but otherwise this "always-up-to-date" Bitcoin node can be kept as a low-resource node, so you can run both nodes in the same machine.
When a new Bitcoin version comes up, you just upgrade the "always-up-to-date" Bitcoin node. This protects you if a future softfork activates, you will only receive valid Bitcoin blocks and transactions. Since this node has nothing running on top of it, it is just a special peer of the "stable-version" node, any software incompatibilities with your system software do not exist.
Your "stable-version" Bitcoin node remains the same version until you are ready to actually upgrade this node and are prepared to rewrite most of the software you have running on top of it due to version compatibility problems.
When upgrading the "always-up-to-date", you can bring it down safely and then start it later. Your "stable-version" wil keep running, disconnected from the network, but otherwise still available for whatever queries. You do need some system to stop the "always-up-to-date" node if for any reason the "stable-version" goes down (otherwisee if the "always-up-to-date" advances its pruning window past what your "stable-version" has, the "stable-version" cannot sync afterwards), but if you are technically competent enough that you need to do this, you are technically competent enough to write such a trivial monitor program (EDIT: gmax notes you can adjust the pruning window by RPC commands to help with this as well).
This recommendation is from gmaxwell on IRC, by the way.

Why i’m bullish on Zilliqa (long read)

Edit: TL;DR added in the comments
 
Hey all, I've been researching coins since 2017 and have gone through 100s of them in the last 3 years. I got introduced to blockchain via Bitcoin of course, analyzed Ethereum thereafter and from that moment I have a keen interest in smart contact platforms. I’m passionate about Ethereum but I find Zilliqa to have a better risk-reward ratio. Especially because Zilliqa has found an elegant balance between being secure, decentralized and scalable in my opinion.
 
Below I post my analysis of why from all the coins I went through I’m most bullish on Zilliqa (yes I went through Tezos, EOS, NEO, VeChain, Harmony, Algorand, Cardano etc.). Note that this is not investment advice and although it's a thorough analysis there is obviously some bias involved. Looking forward to what you all think!
 
Fun fact: the name Zilliqa is a play on ‘silica’ silicon dioxide which means “Silicon for the high-throughput consensus computer.”
 
This post is divided into (i) Technology, (ii) Business & Partnerships, and (iii) Marketing & Community. I’ve tried to make the technology part readable for a broad audience. If you’ve ever tried understanding the inner workings of Bitcoin and Ethereum you should be able to grasp most parts. Otherwise, just skim through and once you are zoning out head to the next part.
 
Technology and some more:
 
Introduction
 
The technology is one of the main reasons why I’m so bullish on Zilliqa. First thing you see on their website is: “Zilliqa is a high-performance, high-security blockchain platform for enterprises and next-generation applications.” These are some bold statements.
 
Before we deep dive into the technology let’s take a step back in time first as they have quite the history. The initial research paper from which Zilliqa originated dates back to August 2016: Elastico: A Secure Sharding Protocol For Open Blockchains where Loi Luu (Kyber Network) is one of the co-authors. Other ideas that led to the development of what Zilliqa has become today are: Bitcoin-NG, collective signing CoSi, ByzCoin and Omniledger.
 
The technical white paper was made public in August 2017 and since then they have achieved everything stated in the white paper and also created their own open source intermediate level smart contract language called Scilla (functional programming language similar to OCaml) too.
 
Mainnet is live since the end of January 2019 with daily transaction rates growing continuously. About a week ago mainnet reached 5 million transactions, 500.000+ addresses in total along with 2400 nodes keeping the network decentralized and secure. Circulating supply is nearing 11 billion and currently only mining rewards are left. The maximum supply is 21 billion with annual inflation being 7.13% currently and will only decrease with time.
 
Zilliqa realized early on that the usage of public cryptocurrencies and smart contracts were increasing but decentralized, secure, and scalable alternatives were lacking in the crypto space. They proposed to apply sharding onto a public smart contract blockchain where the transaction rate increases almost linear with the increase in the amount of nodes. More nodes = higher transaction throughput and increased decentralization. Sharding comes in many forms and Zilliqa uses network-, transaction- and computational sharding. Network sharding opens up the possibility of using transaction- and computational sharding on top. Zilliqa does not use state sharding for now. We’ll come back to this later.
 
Before we continue dissecting how Zilliqa achieves such from a technological standpoint it’s good to keep in mind that a blockchain being decentralised and secure and scalable is still one of the main hurdles in allowing widespread usage of decentralised networks. In my opinion this needs to be solved first before blockchains can get to the point where they can create and add large scale value. So I invite you to read the next section to grasp the underlying fundamentals. Because after all these premises need to be true otherwise there isn’t a fundamental case to be bullish on Zilliqa, right?
 
Down the rabbit hole
 
How have they achieved this? Let’s define the basics first: key players on Zilliqa are the users and the miners. A user is anybody who uses the blockchain to transfer funds or run smart contracts. Miners are the (shard) nodes in the network who run the consensus protocol and get rewarded for their service in Zillings (ZIL). The mining network is divided into several smaller networks called shards, which is also referred to as ‘network sharding’. Miners subsequently are randomly assigned to a shard by another set of miners called DS (Directory Service) nodes. The regular shards process transactions and the outputs of these shards are eventually combined by the DS shard as they reach consensus on the final state. More on how these DS shards reach consensus (via pBFT) will be explained later on.
 
The Zilliqa network produces two types of blocks: DS blocks and Tx blocks. One DS Block consists of 100 Tx Blocks. And as previously mentioned there are two types of nodes concerned with reaching consensus: shard nodes and DS nodes. Becoming a shard node or DS node is being defined by the result of a PoW cycle (Ethash) at the beginning of the DS Block. All candidate mining nodes compete with each other and run the PoW (Proof-of-Work) cycle for 60 seconds and the submissions achieving the highest difficulty will be allowed on the network. And to put it in perspective: the average difficulty for one DS node is ~ 2 Th/s equaling 2.000.000 Mh/s or 55 thousand+ GeForce GTX 1070 / 8 GB GPUs at 35.4 Mh/s. Each DS Block 10 new DS nodes are allowed. And a shard node needs to provide around 8.53 GH/s currently (around 240 GTX 1070s). Dual mining ETH/ETC and ZIL is possible and can be done via mining software such as Phoenix and Claymore. There are pools and if you have large amounts of hashing power (Ethash) available you could mine solo.
 
The PoW cycle of 60 seconds is a peak performance and acts as an entry ticket to the network. The entry ticket is called a sybil resistance mechanism and makes it incredibly hard for adversaries to spawn lots of identities and manipulate the network with these identities. And after every 100 Tx Blocks which corresponds to roughly 1,5 hour this PoW process repeats. In between these 1,5 hour, no PoW needs to be done meaning Zilliqa’s energy consumption to keep the network secure is low. For more detailed information on how mining works click here.
Okay, hats off to you. You have made it this far. Before we go any deeper down the rabbit hole we first must understand why Zilliqa goes through all of the above technicalities and understand a bit more what a blockchain on a more fundamental level is. Because the core of Zilliqa’s consensus protocol relies on the usage of pBFT (practical Byzantine Fault Tolerance) we need to know more about state machines and their function. Navigate to Viewblock, a Zilliqa block explorer, and just come back to this article. We will use this site to navigate through a few concepts.
 
We have established that Zilliqa is a public and distributed blockchain. Meaning that everyone with an internet connection can send ZILs, trigger smart contracts, etc. and there is no central authority who fully controls the network. Zilliqa and other public and distributed blockchains (like Bitcoin and Ethereum) can also be defined as state machines.
 
Taking the liberty of paraphrasing examples and definitions given by Samuel Brooks’ medium article, he describes the definition of a blockchain (like Zilliqa) as: “A peer-to-peer, append-only datastore that uses consensus to synchronize cryptographically-secure data”.
 
Next, he states that: "blockchains are fundamentally systems for managing valid state transitions”. For some more context, I recommend reading the whole medium article to get a better grasp of the definitions and understanding of state machines. Nevertheless, let’s try to simplify and compile it into a single paragraph. Take traffic lights as an example: all its states (red, amber, and green) are predefined, all possible outcomes are known and it doesn’t matter if you encounter the traffic light today or tomorrow. It will still behave the same. Managing the states of a traffic light can be done by triggering a sensor on the road or pushing a button resulting in one traffic lights’ state going from green to red (via amber) and another light from red to green.
 
With public blockchains like Zilliqa, this isn’t so straightforward and simple. It started with block #1 almost 1,5 years ago and every 45 seconds or so a new block linked to the previous block is being added. Resulting in a chain of blocks with transactions in it that everyone can verify from block #1 to the current #647.000+ block. The state is ever changing and the states it can find itself in are infinite. And while the traffic light might work together in tandem with various other traffic lights, it’s rather insignificant comparing it to a public blockchain. Because Zilliqa consists of 2400 nodes who need to work together to achieve consensus on what the latest valid state is while some of these nodes may have latency or broadcast issues, drop offline or are deliberately trying to attack the network, etc.
 
Now go back to the Viewblock page take a look at the amount of transaction, addresses, block and DS height and then hit refresh. Obviously as expected you see new incremented values on one or all parameters. And how did the Zilliqa blockchain manage to transition from a previous valid state to the latest valid state? By using pBFT to reach consensus on the latest valid state.
 
After having obtained the entry ticket, miners execute pBFT to reach consensus on the ever-changing state of the blockchain. pBFT requires a series of network communication between nodes, and as such there is no GPU involved (but CPU). Resulting in the total energy consumed to keep the blockchain secure, decentralized and scalable being low.
 
pBFT stands for practical Byzantine Fault Tolerance and is an optimization on the Byzantine Fault Tolerant algorithm. To quote Blockonomi: “In the context of distributed systems, Byzantine Fault Tolerance is the ability of a distributed computer network to function as desired and correctly reach a sufficient consensus despite malicious components (nodes) of the system failing or propagating incorrect information to other peers.” Zilliqa is such a distributed computer network and depends on the honesty of the nodes (shard and DS) to reach consensus and to continuously update the state with the latest block. If pBFT is a new term for you I can highly recommend the Blockonomi article.
 
The idea of pBFT was introduced in 1999 - one of the authors even won a Turing award for it - and it is well researched and applied in various blockchains and distributed systems nowadays. If you want more advanced information than the Blockonomi link provides click here. And if you’re in between Blockonomi and the University of Singapore read the Zilliqa Design Story Part 2 dating from October 2017.
Quoting from the Zilliqa tech whitepaper: “pBFT relies upon a correct leader (which is randomly selected) to begin each phase and proceed when the sufficient majority exists. In case the leader is byzantine it can stall the entire consensus protocol. To address this challenge, pBFT offers a view change protocol to replace the byzantine leader with another one.”
 
pBFT can tolerate ⅓ of the nodes being dishonest (offline counts as Byzantine = dishonest) and the consensus protocol will function without stalling or hiccups. Once there are more than ⅓ of dishonest nodes but no more than ⅔ the network will be stalled and a view change will be triggered to elect a new DS leader. Only when more than ⅔ of the nodes are dishonest (66%) double-spend attacks become possible.
 
If the network stalls no transactions can be processed and one has to wait until a new honest leader has been elected. When the mainnet was just launched and in its early phases, view changes happened regularly. As of today the last stalling of the network - and view change being triggered - was at the end of October 2019.
 
Another benefit of using pBFT for consensus besides low energy is the immediate finality it provides. Once your transaction is included in a block and the block is added to the chain it’s done. Lastly, take a look at this article where three types of finality are being defined: probabilistic, absolute and economic finality. Zilliqa falls under the absolute finality (just like Tendermint for example). Although lengthy already we skipped through some of the inner workings from Zilliqa’s consensus: read the Zilliqa Design Story Part 3 and you will be close to having a complete picture on it. Enough about PoW, sybil resistance mechanism, pBFT, etc. Another thing we haven’t looked at yet is the amount of decentralization.
 
Decentralisation
 
Currently, there are four shards, each one of them consisting of 600 nodes. 1 shard with 600 so-called DS nodes (Directory Service - they need to achieve a higher difficulty than shard nodes) and 1800 shard nodes of which 250 are shard guards (centralized nodes controlled by the team). The amount of shard guards has been steadily declining from 1200 in January 2019 to 250 as of May 2020. On the Viewblock statistics, you can see that many of the nodes are being located in the US but those are only the (CPU parts of the) shard nodes who perform pBFT. There is no data from where the PoW sources are coming. And when the Zilliqa blockchain starts reaching its transaction capacity limit, a network upgrade needs to be executed to lift the current cap of maximum 2400 nodes to allow more nodes and formation of more shards which will allow to network to keep on scaling according to demand.
Besides shard nodes there are also seed nodes. The main role of seed nodes is to serve as direct access points (for end-users and clients) to the core Zilliqa network that validates transactions. Seed nodes consolidate transaction requests and forward these to the lookup nodes (another type of nodes) for distribution to the shards in the network. Seed nodes also maintain the entire transaction history and the global state of the blockchain which is needed to provide services such as block explorers. Seed nodes in the Zilliqa network are comparable to Infura on Ethereum.
 
The seed nodes were first only operated by Zilliqa themselves, exchanges and Viewblock. Operators of seed nodes like exchanges had no incentive to open them for the greater public. They were centralised at first. Decentralisation at the seed nodes level has been steadily rolled out since March 2020 ( Zilliqa Improvement Proposal 3 ). Currently the amount of seed nodes is being increased, they are public-facing and at the same time PoS is applied to incentivize seed node operators and make it possible for ZIL holders to stake and earn passive yields. Important distinction: seed nodes are not involved with consensus! That is still PoW as entry ticket and pBFT for the actual consensus.
 
5% of the block rewards are being assigned to seed nodes (from the beginning in 2019) and those are being used to pay out ZIL stakers. The 5% block rewards with an annual yield of 10.03% translate to roughly 610 MM ZILs in total that can be staked. Exchanges use the custodial variant of staking and wallets like Moonlet will use the non-custodial version (starting in Q3 2020). Staking is being done by sending ZILs to a smart contract created by Zilliqa and audited by Quantstamp.
 
With a high amount of DS; shard nodes and seed nodes becoming more decentralized too, Zilliqa qualifies for the label of decentralized in my opinion.
 
Smart contracts
 
Let me start by saying I’m not a developer and my programming skills are quite limited. So I‘m taking the ELI5 route (maybe 12) but if you are familiar with Javascript, Solidity or specifically OCaml please head straight to Scilla - read the docs to get a good initial grasp of how Zilliqa’s smart contract language Scilla works and if you ask yourself “why another programming language?” check this article. And if you want to play around with some sample contracts in an IDE click here. The faucet can be found here. And more information on architecture, dapp development and API can be found on the Developer Portal.
If you are more into listening and watching: check this recent webinar explaining Zilliqa and Scilla. Link is time-stamped so you’ll start right away with a platform introduction, roadmap 2020 and afterwards a proper Scilla introduction.
 
Generalized: programming languages can be divided into being ‘object-oriented’ or ‘functional’. Here is an ELI5 given by software development academy: * “all programs have two basic components, data – what the program knows – and behavior – what the program can do with that data. So object-oriented programming states that combining data and related behaviors in one place, is called “object”, which makes it easier to understand how a particular program works. On the other hand, functional programming argues that data and behavior are different things and should be separated to ensure their clarity.” *
 
Scilla is on the functional side and shares similarities with OCaml: OCaml is a general-purpose programming language with an emphasis on expressiveness and safety. It has an advanced type system that helps catch your mistakes without getting in your way. It's used in environments where a single mistake can cost millions and speed matters, is supported by an active community, and has a rich set of libraries and development tools. For all its power, OCaml is also pretty simple, which is one reason it's often used as a teaching language.
 
Scilla is blockchain agnostic, can be implemented onto other blockchains as well, is recognized by academics and won a so-called Distinguished Artifact Award award at the end of last year.
 
One of the reasons why the Zilliqa team decided to create their own programming language focused on preventing smart contract vulnerabilities is that adding logic on a blockchain, programming, means that you cannot afford to make mistakes. Otherwise, it could cost you. It’s all great and fun blockchains being immutable but updating your code because you found a bug isn’t the same as with a regular web application for example. And with smart contracts, it inherently involves cryptocurrencies in some form thus value.
 
Another difference with programming languages on a blockchain is gas. Every transaction you do on a smart contract platform like Zilliqa or Ethereum costs gas. With gas you basically pay for computational costs. Sending a ZIL from address A to address B costs 0.001 ZIL currently. Smart contracts are more complex, often involve various functions and require more gas (if gas is a new concept click here ).
 
So with Scilla, similar to Solidity, you need to make sure that “every function in your smart contract will run as expected without hitting gas limits. An improper resource analysis may lead to situations where funds may get stuck simply because a part of the smart contract code cannot be executed due to gas limits. Such constraints are not present in traditional software systems”. Scilla design story part 1
 
Some examples of smart contract issues you’d want to avoid are: leaking funds, ‘unexpected changes to critical state variables’ (example: someone other than you setting his or her address as the owner of the smart contract after creation) or simply killing a contract.
 
Scilla also allows for formal verification. Wikipedia to the rescue: In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics.
 
Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code.
 
Scilla is being developed hand-in-hand with formalization of its semantics and its embedding into the Coq proof assistant — a state-of-the art tool for mechanized proofs about properties of programs.”
 
Simply put, with Scilla and accompanying tooling developers can be mathematically sure and proof that the smart contract they’ve written does what he or she intends it to do.
 
Smart contract on a sharded environment and state sharding
 
There is one more topic I’d like to touch on: smart contract execution in a sharded environment (and what is the effect of state sharding). This is a complex topic. I’m not able to explain it any easier than what is posted here. But I will try to compress the post into something easy to digest.
 
Earlier on we have established that Zilliqa can process transactions in parallel due to network sharding. This is where the linear scalability comes from. We can define simple transactions: a transaction from address A to B (Category 1), a transaction where a user interacts with one smart contract (Category 2) and the most complex ones where triggering a transaction results in multiple smart contracts being involved (Category 3). The shards are able to process transactions on their own without interference of the other shards. With Category 1 transactions that is doable, with Category 2 transactions sometimes if that address is in the same shard as the smart contract but with Category 3 you definitely need communication between the shards. Solving that requires to make a set of communication rules the protocol needs to follow in order to process all transactions in a generalised fashion.
 
And this is where the downsides of state sharding comes in currently. All shards in Zilliqa have access to the complete state. Yes the state size (0.1 GB at the moment) grows and all of the nodes need to store it but it also means that they don’t need to shop around for information available on other shards. Requiring more communication and adding more complexity.

Roadmap / Zilliqa 2.0
 
There is no strict defined roadmap but here are topics being worked on. And via the Zilliqa website there is also more information on the projects they are working on.
 
Business & Partnerships
 
It’s not only technology in which Zilliqa seems to be excelling as their ecosystem has been expanding and starting to grow rapidly. The project is on a mission to provide OpenFinance (OpFi) to the world and Singapore is the right place to be due to its progressive regulations and futuristic thinking. Singapore has taken a proactive approach towards cryptocurrencies by introducing the Payment Services Act 2019 (PS Act). Among other things, the PS Act will regulate intermediaries dealing with certain cryptocurrencies, with a particular focus on consumer protection and anti-money laundering. It will also provide a stable regulatory licensing and operating framework for cryptocurrency entities, effectively covering all crypto businesses and exchanges based in Singapore. According to PWC 82% of the surveyed executives in Singapore reported blockchain initiatives underway and 13% of them have already brought the initiatives live to the market. There is also an increasing list of organizations that are starting to provide digital payment services. Moreover, Singaporean blockchain developers Building Cities Beyond has recently created an innovation $15 million grant to encourage development on its ecosystem. This all suggests that Singapore tries to position itself as (one of) the leading blockchain hubs in the world.
 
Zilliqa seems to already take advantage of this and recently helped launch Hg Exchange on their platform, together with financial institutions PhillipCapital, PrimePartners and Fundnel. Hg Exchange, which is now approved by the Monetary Authority of Singapore (MAS), uses smart contracts to represent digital assets. Through Hg Exchange financial institutions worldwide can use Zilliqa's safe-by-design smart contracts to enable the trading of private equities. For example, think of companies such as Grab, Airbnb, SpaceX that are not available for public trading right now. Hg Exchange will allow investors to buy shares of private companies & unicorns and capture their value before an IPO. Anquan, the main company behind Zilliqa, has also recently announced that they became a partner and shareholder in TEN31 Bank, which is a fully regulated bank allowing for tokenization of assets and is aiming to bridge the gap between conventional banking and the blockchain world. If STOs, the tokenization of assets, and equity trading will continue to increase, then Zilliqa’s public blockchain would be the ideal candidate due to its strategic positioning, partnerships, regulatory compliance and the technology that is being built on top of it.
 
What is also very encouraging is their focus on banking the un(der)banked. They are launching a stablecoin basket starting with XSGD. As many of you know, stablecoins are currently mostly used for trading. However, Zilliqa is actively trying to broaden the use case of stablecoins. I recommend everybody to read this text that Amrit Kumar wrote (one of the co-founders). These stablecoins will be integrated in the traditional markets and bridge the gap between the crypto world and the traditional world. This could potentially revolutionize and legitimise the crypto space if retailers and companies will for example start to use stablecoins for payments or remittances, instead of it solely being used for trading.
 
Zilliqa also released their DeFi strategic roadmap (dating November 2019) which seems to be aligning well with their OpFi strategy. A non-custodial DEX is coming to Zilliqa made by Switcheo which allows cross-chain trading (atomic swaps) between ETH, EOS and ZIL based tokens. They also signed a Memorandum of Understanding for a (soon to be announced) USD stablecoin. And as Zilliqa is all about regulations and being compliant, I’m speculating on it to be a regulated USD stablecoin. Furthermore, XSGD is already created and visible on block explorer and XIDR (Indonesian Stablecoin) is also coming soon via StraitsX. Here also an overview of the Tech Stack for Financial Applications from September 2019. Further quoting Amrit Kumar on this:
 
There are two basic building blocks in DeFi/OpFi though: 1) stablecoins as you need a non-volatile currency to get access to this market and 2) a dex to be able to trade all these financial assets. The rest are built on top of these blocks.
 
So far, together with our partners and community, we have worked on developing these building blocks with XSGD as a stablecoin. We are working on bringing a USD-backed stablecoin as well. We will soon have a decentralised exchange developed by Switcheo. And with HGX going live, we are also venturing into the tokenization space. More to come in the future.”
 
Additionally, they also have this ZILHive initiative that injects capital into projects. There have been already 6 waves of various teams working on infrastructure, innovation and research, and they are not from ASEAN or Singapore only but global: see Grantees breakdown by country. Over 60 project teams from over 20 countries have contributed to Zilliqa's ecosystem. This includes individuals and teams developing wallets, explorers, developer toolkits, smart contract testing frameworks, dapps, etc. As some of you may know, Unstoppable Domains (UD) blew up when they launched on Zilliqa. UD aims to replace cryptocurrency addresses with a human-readable name and allows for uncensorable websites. Zilliqa will probably be the only one able to handle all these transactions onchain due to ability to scale and its resulting low fees which is why the UD team launched this on Zilliqa in the first place. Furthermore, Zilliqa also has a strong emphasis on security, compliance, and privacy, which is why they partnered with companies like Elliptic, ChainSecurity (part of PwC Switzerland), and Incognito. Their sister company Aqilliz (Zilliqa spelled backwards) focuses on revolutionizing the digital advertising space and is doing interesting things like using Zilliqa to track outdoor digital ads with companies like Foodpanda.
 
Zilliqa is listed on nearly all major exchanges, having several different fiat-gateways and recently have been added to Binance’s margin trading and futures trading with really good volume. They also have a very impressive team with good credentials and experience. They don't just have “tech people”. They have a mix of tech people, business people, marketeers, scientists, and more. Naturally, it's good to have a mix of people with different skill sets if you work in the crypto space.
 
Marketing & Community
 
Zilliqa has a very strong community. If you just follow their Twitter their engagement is much higher for a coin that has approximately 80k followers. They also have been ‘coin of the day’ by LunarCrush many times. LunarCrush tracks real-time cryptocurrency value and social data. According to their data, it seems Zilliqa has a more fundamental and deeper understanding of marketing and community engagement than almost all other coins. While almost all coins have been a bit frozen in the last months, Zilliqa seems to be on its own bull run. It was somewhere in the 100s a few months ago and is currently ranked #46 on CoinGecko. Their official Telegram also has over 20k people and is very active, and their community channel which is over 7k now is more active and larger than many other official channels. Their local communities also seem to be growing.
 
Moreover, their community started ‘Zillacracy’ together with the Zilliqa core team ( see www.zillacracy.com ). It’s a community-run initiative where people from all over the world are now helping with marketing and development on Zilliqa. Since its launch in February 2020 they have been doing a lot and will also run their own non-custodial seed node for staking. This seed node will also allow them to start generating revenue for them to become a self sustaining entity that could potentially scale up to become a decentralized company working in parallel with the Zilliqa core team. Comparing it to all the other smart contract platforms (e.g. Cardano, EOS, Tezos etc.) they don't seem to have started a similar initiative (correct me if I’m wrong though). This suggests in my opinion that these other smart contract platforms do not fully understand how to utilize the ‘power of the community’. This is something you cannot ‘buy with money’ and gives many projects in the space a disadvantage.
 
Zilliqa also released two social products called SocialPay and Zeeves. SocialPay allows users to earn ZILs while tweeting with a specific hashtag. They have recently used it in partnership with the Singapore Red Cross for a marketing campaign after their initial pilot program. It seems like a very valuable social product with a good use case. I can see a lot of traditional companies entering the space through this product, which they seem to suggest will happen. Tokenizing hashtags with smart contracts to get network effect is a very smart and innovative idea.
 
Regarding Zeeves, this is a tipping bot for Telegram. They already have 1000s of signups and they plan to keep upgrading it for more and more people to use it (e.g. they recently have added a quiz features). They also use it during AMAs to reward people in real-time. It’s a very smart approach to grow their communities and get familiar with ZIL. I can see this becoming very big on Telegram. This tool suggests, again, that the Zilliqa team has a deeper understanding of what the crypto space and community needs and is good at finding the right innovative tools to grow and scale.
 
To be honest, I haven’t covered everything (i’m also reaching the character limited haha). So many updates happening lately that it's hard to keep up, such as the International Monetary Fund mentioning Zilliqa in their report, custodial and non-custodial Staking, Binance Margin, Futures, Widget, entering the Indian market, and more. The Head of Marketing Colin Miles has also released this as an overview of what is coming next. And last but not least, Vitalik Buterin has been mentioning Zilliqa lately acknowledging Zilliqa and mentioning that both projects have a lot of room to grow. There is much more info of course and a good part of it has been served to you on a silver platter. I invite you to continue researching by yourself :-) And if you have any comments or questions please post here!

Online gambling legislation and regulation. Starting your own gambling product.

Online gambling legislation and regulation. Starting your own gambling product.

Mobile gambling
If you plan to develop an app with the ability to deposit and withdraw real money, then such a product automatically falls into the category of gambling and you will need to license your business for successful operation.
Mobile and Web Based Apps
So let’s talk about the different kinds of online gambling apps available on web and mobile. We’ll be covering both free-play gaming apps and real money casino app games you can find for iOS, Android devices and web browsers.
Mobile gambling is more common for poker, casino, bingo, and skill games. They have advantages in terms of a low barrier to enter the market, instant liquidity, product knowledge, and marketing expertise, minimal infrastructure costs, and the ability to bring a brand to the market quickly. Consequently, this form of gambling does not sit neatly with jurisdictional boundaries. Multiple gambling opportunities are available, including betting on various events and markets, in a relatively simple format. Gambling products can also be integrated into betting on television shows or virtual racing and sports games as well as offering lotteries, bingo, poker and casino games.
Most Popular Gambling Apps
Sports betting, casino, poker and lotteries are the most popular forms of online gambling. However, other forms are available too. These include the following: Bingo, slot machines, different card games, roulette and other game of chance. One of the best things about online gambling and betting apps is the number of choices you have.

Sports Betting

Betting means making or accepting a bet on the outcome of a race, competition, or other event or process, the likelihood of anything occurring or not occurring, or whether anything is or is not true. Today most sports betting is done via mobile-friendly sites and apps.
Today most sports betting is done via mobile-friendly sites and apps.
The introduction of live betting for sports like soccer and tennis means that bettors who are sitting inside stadiums watching games can now pick up their mobile devices and find real-time betting value with the best sports gambling apps. This has really unlocked a door to the future of sports gambling and the popularity of online gambling apps.

Poker

Many sites offer free poker, where no real money is wagered, although in some cases players can accumulate credits that can be exchanged for prizes. This is the case why people are going to play for real money. There is an ongoing debate over whether poker should be classified as a game of chance or skill. The parameters of legal poker playing are still unclear and differ between jurisdictions. Since you are not gambling with money, I’m pretty sure under the law it’s just a video game for now.

Blackjack

Blackjack is the game of choice to many high-rollers and do you know why? Because blackjack is a challenging, logic and skill-based game where your thinking, strategy, and calculations determine the outcome of the game.

Bingo

Bingo is one of the most popular and socially accepted games in the world. Bingo is a traditional form of gambling that has seen considerable innovation in recent years. It is also the only form of gambling recognized in the Gambling Act that does not have a specific statutory definition, the Act providing simply that “bingo” means “any version of that game, irrespective of by what name it is described”. Bingo must be played as an equal chance game. For game to be classed as “bingo” it must meet the Act’s definition of “equal chance gaming” (as opposed to casino gaming). Thus, it: must not involve playing or staking against a bank, and must be a game in which the chances are equally favorable to all participants in the sense that each ticket or chance has the same probability of success as any other.
Licensed bingo is a well-regulated and socially responsible form of gambling that takes place in a safe environment. Many sites offer multiple forms of bingo with different features, types of games, and costs of play. These sites often cater specifically for women and some research suggests that they may appeal to markets who would not typically engage in traditional forms of gambling.

Slots

Slot machine is one of the most beloved game among the gambling community and it has been a part of the industry for a long time. They provide fun and entertainment and their simplicity allows gamers to start playing at once. This can play out in different ways depending on the machine you’re playing. For instance, there’s Pick a Fortune, a five-reel, 20 line game that puts players right in the studio of a television game show, including the potential to play a Deal or No Deal-style bonus round. A super trend over the past few years is mobile-friendly slot games. These apps and websites were developed to enable players to enjoy their favorite games on their smartphones at any time. Another dominant slot trend is licensed branded slots that are based on popular movies, television, and musicians.
Virtual Money vs Real Money
Let’s find out the difference between social gambling and real money gambling, as well as the differences between gambling through apps and gambling through a web browser. It can be quite confusing trawling through all the casinos, slots, and lotteries available, both through your mobile web browser as well as through mobile app stores, in the form of downloadable apps.

Virtual money

The main difference between virtual money and real money gambling is that the in-game virtual currency in social games and gambling-type games is used only like credits that are not paid out as winnings or anything given to player in cash, making these games exempt from gambling regulations.
Virtual money is loaded on user game accounts via in-app purchases in mobile applications or the game balance funding from a card via web based applications.

Real money gambling

Real money gambling via your mobile device is only allowed in countries where laws have been passed that allow for this type of gambling online, or there are no laws in place that prevent it. The payment systems are the legal way of services payment in the gambling app, performing as the intermediary between the gambling facility and the client. With their help, users replenish deposits and withdraw funds to personal accounts in financial institutions. If the application uses the payment system of a well-known brand, that gives players additional confidence in the resource. Nowadays, there is a wide range of payment systems, some of which operate all over the world, other systems are oriented towards the citizens of one or several countries. A number of services accept money of different world currencies, while others allow currency transactions of one state only.
What is an Online Gambling Licensing
The internet has a global audience, there’s no single piece of legislation that covers the legality of online gambling for the entire world. Mobile gambling doesn’t typically accept customers from every single country in the world. It often focuses on certain specific regions.
Instead, most countries have their own local laws that deal with the relevant legal and regulatory issues.
Ultimately, questions of legality all go back to the location of the casino or where the website operates out of. In closed regulatory systems, such as Italy, France, and the Netherlands, licenses, and advertising rights are limited to domestic providers, which must be located within their country’s geographical boundaries and these are only permitted to offer some types of products. Some jurisdictions, for example, Norway, Sweden, and Canada legalize and regulate online gambling, but this is limited to a single site that is owned by the government. Under such an approach, the government becomes the operator and regulator and all revenues are returned to the government.
Remote gambling is generally permitted. That means that an operator that is licensed may provide gambling services to citizens in the country via all forms of remote communication (and using equipment that may be located in the country or abroad). Equally, a remote operator may be licensed to offer gambling services to citizens in any jurisdiction in the world using equipment located in the country. The law provides that, for each type of gambling (betting, gaming, and participating in a lottery), there will be two forms of license available: remote and non-remote forms (land-based). If you provide facilities for remote gambling, online or through other means, and advertise to consumers you will need a license from the licensing jurisdictions or local licensing authorities. Before an online gambling site signs up its first customer, before it accepts its first bet before the first card is dealt, it must be licensed by a recognized governmental entity.
Certain regions in the world have specific legislation in place that allows them to license and regulate companies that operate online gambling sites or provide industry services (such as the supply of gaming software). These regions are referred to as online gambling jurisdictions or licensing jurisdictions.
Depending on what type of entertainment you are going to implement in your internet establishment, you will have to apply for the corresponding permissions. Online gambling laws in Europe vary from one country to the next. The industry is well regulated in some countries and less so in others. There are several online gambling jurisdictions located in Europe. Some of these are members of the European Union (EU), and thus subject to the various rules and regulations of that body, while others are independent. Each of these jurisdictions has an authority that’s responsible for approving gambling sites for licenses that enable them to offer their services legally. They also regulate their licensees.
Countries that Provide Gambling Licensing
Today there are lots of licensing jurisdictions located all over the world and offering different terms for their customers. Depending on the country, licenses can be local, international (distributed in several countries), have a different set of documents for registration, costs of registration and further support, various operating conditions and other special details.

Which gambling license is both internationally recognized?

The government of Ireland offers casino operators, software, and service providers in the gambling industry, with a gambling license that allows gambling operators to conduct business related to casino, lotto, and other gaming-related activities. Ireland Gambling License is one of the most popular license for online casinos worldwide. Ireland has long been recognized as one of the preferred locations for Online Gambling operators to base their operations. This success has been due to a combination of factors, such as a progressive legislative system, political stability, first-rate telecommunications facilities, and a well established financial services industry. A wide range of gambling sites operates out of Ireland including sports betting, casino sites, poker, bingo, and more.
In stark contrast, the UK is the largest regulated market for online gambling in the world, and corporations are already comfortable exploiting the intersections of gambling and gaming, betting in-play, social gaming, Bitcoin, financial trading and spread betting, betting exchanges, e-sports and, most profitably, mobile gambling. 40% and 60% of online gambling in the UK took place in Gibraltar.

International licensing

Europe is home to the following online gambling jurisdictions: Alderney, Gibraltar, Isle of Man, Malta. Malta is currently the country that is most accommodating to gambling companies, and the license offers whitelisted online gambling in sports and casino games in many European territories. But takes an extreme amount of time in paperwork and background checks. Also, you pay 5% of all your gross profit to the EU.
Among countries offering gambling licensing services, the attention should be paid to Curaçao jurisdiction, which is considered to be one of the most promising for the online gaming business.
Curaçao Internet Gaming Association (also known as Curaçao eGaming) is both a regulator and a licensor, and its licensing works worldwide except Curaçao itself, USA, France and Netherlands. Using Curacao as an example, let us examine in detail the process of obtaining a license, the necessary documents and expenses.
How to get a License on Curaçao
  • Documents necessary for company registration:
  • criminal record;
  • passport scans;
  • bank account confirmation;
  • documents proving payments for utility services.
After the company is registered, an operator can apply for the license providing the following documents:
  • a document certifying the right of domain possession;
  • description of games planned to be used in the project;
  • a list indicating countries of potential operation;
  • illustration of server locations to be used in the project;
  • a copy of the agreement with a software provider.
Gambling license cost:
  • Bank account opening $1000
  • Company registration $3600
  • Company management per year $3600
  • Application processing fee $1000
  • License fee per year $4800
  • Equipment/software fee starting from $1500
  • Server maintenance per year $6000
Apart from that pay for technical support and maintenance every year. The entire license issuing process takes between 2-4 weeks. Curacao Internet Gaming Association (CIGA) also has the power to review a license and, if it finds that an operator has breached a license condition, has the power to impose a range of sanctions including revocation of the license.
Apple and Google Gambling Rules
You’ll be surprised at the limited number of real money gambling app options available on the AppStore and Google Play Store. Most real money casino gaming is done through gambler’s mobile web browsers and not through mobile gambling apps that you’ll find for iPhone and Android phones. Apple allows online gambling applications in a few forms, and not just in places where it is explicitly permitted. They do not allow any payments through the applications – those have to be done on the websites. Apple has far stricter developer guidelines for iOS apps than Google does for Android apps, so it’s fine to assume that whatever you choose to download from iTunes is usually safe, secure, and meets a certain standard.
Any real money casino in the iTunes app is required to have proper licensing and permissions before Apple will approve the app for use or downloads. While Google Play is technically regulated, it is much more loose in what can be hosted.

Apple Store

Gambling, gaming, and lotteries can be tricky to manage and tend to be one of the most-regulated offerings on the App Store. Apple has rules for apps that support real money wagering, including sports betting and poker. Those apps and lotteries must have necessary licensing and permissions in the locations where the App is used, must be geo-restricted to those locations, and must be free on the App Store, and Apple rate even simulated gambling apps as appropriate only for users 17-years-old and up.

Play Store

Google keeps the reigns tight. To be able to successfully upload apps to the Google Play store, developers need to have a valid license for the specific countries they are targeting and comply with their regulations. The app must be free to download and must prevent under-age users from gambling in the app. As a final precaution, all gambling apps are required to display prominent information regarding responsible gambling practices. This brings its policy in line with the Apple App Store.
Countries where gambling is illegal
It is also important to remember that while gambling is growing rapidly in many places, in others it is totally or partially prohibited. As well as in the majority of the US, sports betting is illegal in India, Pakistan, and China, three of the largest gambling markets in the world. Most countries have rules against gambling. Almost all Islamic countries prohibit gambling of every kind, but many turn a blind eye to online gambling or simply do not have regulations in place for this grey area.
In the United Arab Emirates, however, any kind of gambling is prosecuted. National lotteries are the only legal forms of wagering on the Asian country’s mainland. Cambodia, North Korea strictly forbids online and offline gambling amongst its own citizens but allows tourists to participate in these activities.
Qatar is the strictest country of all when it comes to gambling laws. All forms of gambling activities are considered illegal, and even sports betting is not permissible.
Starting your own gambling product
Numerous online casino platforms in the market offer fantastic casino games like bingo, poker, roulette, and many more.
If you have an idea, but don’t know where to start, we advise you begin with a Minimal Viable Product (MVP) to pilot your proof of concept for investors. MVP spotlights your core features and lets your investors know there are bigger and better things to come.
For MVP you do not need a large team, just a few people are enough to create a fully functioning prototype. In the case of successful numbers of your prototype, the further development of a full-fledged product will require more team, resources and time, however you will be sure that your development and your costs will pay off.

Why i’m bullish on Zilliqa (long read)

Hey all, I've been researching coins since 2017 and have gone through 100s of them in the last 3 years. I got introduced to blockchain via Bitcoin of course, analysed Ethereum thereafter and from that moment I have a keen interest in smart contact platforms. I’m passionate about Ethereum but I find Zilliqa to have a better risk reward ratio. Especially because Zilliqa has found an elegant balance between being secure, decentralised and scalable in my opinion.
 
Below I post my analysis why from all the coins I went through I’m most bullish on Zilliqa (yes I went through Tezos, EOS, NEO, VeChain, Harmony, Algorand, Cardano etc.). Note that this is not investment advice and although it's a thorough analysis there is obviously some bias involved. Looking forward to what you all think!
 
Fun fact: the name Zilliqa is a play on ‘silica’ silicon dioxide which means “Silicon for the high-throughput consensus computer.”
 
This post is divided into (i) Technology, (ii) Business & Partnerships, and (iii) Marketing & Community. I’ve tried to make the technology part readable for a broad audience. If you’ve ever tried understanding the inner workings of Bitcoin and Ethereum you should be able to grasp most parts. Otherwise just skim through and once you are zoning out head to the next part.
 
Technology and some more:
 
Introduction The technology is one of the main reasons why I’m so bullish on Zilliqa. First thing you see on their website is: “Zilliqa is a high-performance, high-security blockchain platform for enterprises and next-generation applications.” These are some bold statements.
 
Before we deep dive into the technology let’s take a step back in time first as they have quite the history. The initial research paper from which Zilliqa originated dates back to August 2016: Elastico: A Secure Sharding Protocol For Open Blockchains where Loi Luu (Kyber Network) is one of the co-authors. Other ideas that led to the development of what Zilliqa has become today are: Bitcoin-NG, collective signing CoSi, ByzCoin and Omniledger.
 
The technical white paper was made public in August 2017 and since then they have achieved everything stated in the white paper and also created their own open source intermediate level smart contract language called Scilla (functional programming language similar to OCaml) too.
 
Mainnet is live since end of January 2019 with daily transaction rate growing continuously. About a week ago mainnet reached 5 million transactions, 500.000+ addresses in total along with 2400 nodes keeping the network decentralised and secure. Circulating supply is nearing 11 billion and currently only mining rewards are left. Maximum supply is 21 billion with annual inflation being 7.13% currently and will only decrease with time.
 
Zilliqa realised early on that the usage of public cryptocurrencies and smart contracts were increasing but decentralised, secure and scalable alternatives were lacking in the crypto space. They proposed to apply sharding onto a public smart contract blockchain where the transaction rate increases almost linear with the increase in amount of nodes. More nodes = higher transaction throughput and increased decentralisation. Sharding comes in many forms and Zilliqa uses network-, transaction- and computational sharding. Network sharding opens up the possibility of using transaction- and computational sharding on top. Zilliqa does not use state sharding for now. We’ll come back to this later.
 
Before we continue disecting how Zilliqa achieves such from a technological standpoint it’s good to keep in mind that a blockchain being decentralised and secure and scalable is still one of the main hurdles in allowing widespread usage of decentralised networks. In my opinion this needs to be solved first before blockchains can get to the point where they can create and add large scale value. So I invite you to read the next section to grasp the underlying fundamentals. Because after all these premises need to be true otherwise there isn’t a fundamental case to be bullish on Zilliqa, right?
 
Down the rabbit hole
 
How have they achieved this? Let’s define the basics first: key players on Zilliqa are the users and the miners. A user is anybody who uses the blockchain to transfer funds or run smart contracts. Miners are the (shard) nodes in the network who run the consensus protocol and get rewarded for their service in Zillings (ZIL). The mining network is divided into several smaller networks called shards, which is also referred to as ‘network sharding’. Miners subsequently are randomly assigned to a shard by another set of miners called DS (Directory Service) nodes. The regular shards process transactions and the outputs of these shards are eventually combined by the DS shard as they reach consensus on the final state. More on how these DS shards reach consensus (via pBFT) will be explained later on.
 
The Zilliqa network produces two types of blocks: DS blocks and Tx blocks. One DS Block consists of 100 Tx Blocks. And as previously mentioned there are two types of nodes concerned with reaching consensus: shard nodes and DS nodes. Becoming a shard node or DS node is being defined by the result of a PoW cycle (Ethash) at the beginning of the DS Block. All candidate mining nodes compete with each other and run the PoW (Proof-of-Work) cycle for 60 seconds and the submissions achieving the highest difficulty will be allowed on the network. And to put it in perspective: the average difficulty for one DS node is ~ 2 Th/s equaling 2.000.000 Mh/s or 55 thousand+ GeForce GTX 1070 / 8 GB GPUs at 35.4 Mh/s. Each DS Block 10 new DS nodes are allowed. And a shard node needs to provide around 8.53 GH/s currently (around 240 GTX 1070s). Dual mining ETH/ETC and ZIL is possible and can be done via mining software such as Phoenix and Claymore. There are pools and if you have large amounts of hashing power (Ethash) available you could mine solo.
 
The PoW cycle of 60 seconds is a peak performance and acts as an entry ticket to the network. The entry ticket is called a sybil resistance mechanism and makes it incredibly hard for adversaries to spawn lots of identities and manipulate the network with these identities. And after every 100 Tx Blocks which corresponds to roughly 1,5 hour this PoW process repeats. In between these 1,5 hour no PoW needs to be done meaning Zilliqa’s energy consumption to keep the network secure is low. For more detailed information on how mining works click here.
Okay, hats off to you. You have made it this far. Before we go any deeper down the rabbit hole we first must understand why Zilliqa goes through all of the above technicalities and understand a bit more what a blockchain on a more fundamental level is. Because the core of Zilliqa’s consensus protocol relies on the usage of pBFT (practical Byzantine Fault Tolerance) we need to know more about state machines and their function. Navigate to Viewblock, a Zilliqa block explorer, and just come back to this article. We will use this site to navigate through a few concepts.
 
We have established that Zilliqa is a public and distributed blockchain. Meaning that everyone with an internet connection can send ZILs, trigger smart contracts etc. and there is no central authority who fully controls the network. Zilliqa and other public and distributed blockchains (like Bitcoin and Ethereum) can also be defined as state machines.
 
Taking the liberty of paraphrasing examples and definitions given by Samuel Brooks’ medium article, he describes the definition of a blockchain (like Zilliqa) as:
“A peer-to-peer, append-only datastore that uses consensus to synchronise cryptographically-secure data”.
 
Next he states that: >“blockchains are fundamentally systems for managing valid state transitions”.* For some more context, I recommend reading the whole medium article to get a better grasp of the definitions and understanding of state machines. Nevertheless, let’s try to simplify and compile it into a single paragraph. Take traffic lights as an example: all its states (red, amber and green) are predefined, all possible outcomes are known and it doesn’t matter if you encounter the traffic light today or tomorrow. It will still behave the same. Managing the states of a traffic light can be done by triggering a sensor on the road or pushing a button resulting in one traffic lights’ state going from green to red (via amber) and another light from red to green.
 
With public blockchains like Zilliqa this isn’t so straightforward and simple. It started with block #1 almost 1,5 years ago and every 45 seconds or so a new block linked to the previous block is being added. Resulting in a chain of blocks with transactions in it that everyone can verify from block #1 to the current #647.000+ block. The state is ever changing and the states it can find itself in are infinite. And while the traffic light might work together in tandem with various other traffic lights, it’s rather insignificant comparing it to a public blockchain. Because Zilliqa consists of 2400 nodes who need to work together to achieve consensus on what the latest valid state is while some of these nodes may have latency or broadcast issues, drop offline or are deliberately trying to attack the network etc.
 
Now go back to the Viewblock page take a look at the amount of transaction, addresses, block and DS height and then hit refresh. Obviously as expected you see new incremented values on one or all parameters. And how did the Zilliqa blockchain manage to transition from a previous valid state to the latest valid state? By using pBFT to reach consensus on the latest valid state.
 
After having obtained the entry ticket, miners execute pBFT to reach consensus on the ever changing state of the blockchain. pBFT requires a series of network communication between nodes, and as such there is no GPU involved (but CPU). Resulting in the total energy consumed to keep the blockchain secure, decentralised and scalable being low.
 
pBFT stands for practical Byzantine Fault Tolerance and is an optimisation on the Byzantine Fault Tolerant algorithm. To quote Blockonomi: “In the context of distributed systems, Byzantine Fault Tolerance is the ability of a distributed computer network to function as desired and correctly reach a sufficient consensus despite malicious components (nodes) of the system failing or propagating incorrect information to other peers.” Zilliqa is such a distributed computer network and depends on the honesty of the nodes (shard and DS) to reach consensus and to continuously update the state with the latest block. If pBFT is a new term for you I can highly recommend the Blockonomi article.
 
The idea of pBFT was introduced in 1999 - one of the authors even won a Turing award for it - and it is well researched and applied in various blockchains and distributed systems nowadays. If you want more advanced information than the Blockonomi link provides click here. And if you’re in between Blockonomi and University of Singapore read the Zilliqa Design Story Part 2 dating from October 2017.
Quoting from the Zilliqa tech whitepaper: “pBFT relies upon a correct leader (which is randomly selected) to begin each phase and proceed when the sufficient majority exists. In case the leader is byzantine it can stall the entire consensus protocol. To address this challenge, pBFT offers a view change protocol to replace the byzantine leader with another one.”
 
pBFT can tolerate ⅓ of the nodes being dishonest (offline counts as Byzantine = dishonest) and the consensus protocol will function without stalling or hiccups. Once there are more than ⅓ of dishonest nodes but no more than ⅔ the network will be stalled and a view change will be triggered to elect a new DS leader. Only when more than ⅔ of the nodes are dishonest (>66%) double spend attacks become possible.
 
If the network stalls no transactions can be processed and one has to wait until a new honest leader has been elected. When the mainnet was just launched and in its early phases, view changes happened regularly. As of today the last stalling of the network - and view change being triggered - was at the end of October 2019.
 
Another benefit of using pBFT for consensus besides low energy is the immediate finality it provides. Once your transaction is included in a block and the block is added to the chain it’s done. Lastly, take a look at this article where three types of finality are being defined: probabilistic, absolute and economic finality. Zilliqa falls under the absolute finality (just like Tendermint for example). Although lengthy already we skipped through some of the inner workings from Zilliqa’s consensus: read the Zilliqa Design Story Part 3 and you will be close to having a complete picture on it. Enough about PoW, sybil resistance mechanism, pBFT etc. Another thing we haven’t looked at yet is the amount of decentralisation.
 
Decentralisation
 
Currently there are four shards, each one of them consisting of 600 nodes. 1 shard with 600 so called DS nodes (Directory Service - they need to achieve a higher difficulty than shard nodes) and 1800 shard nodes of which 250 are shard guards (centralised nodes controlled by the team). The amount of shard guards has been steadily declining from 1200 in January 2019 to 250 as of May 2020. On the Viewblock statistics you can see that many of the nodes are being located in the US but those are only the (CPU parts of the) shard nodes who perform pBFT. There is no data from where the PoW sources are coming. And when the Zilliqa blockchain starts reaching their transaction capacity limit, a network upgrade needs to be executed to lift the current cap of maximum 2400 nodes to allow more nodes and formation of more shards which will allow to network to keep on scaling according to demand.
Besides shard nodes there are also seed nodes. The main role of seed nodes is to serve as direct access points (for end users and clients) to the core Zilliqa network that validates transactions. Seed nodes consolidate transaction requests and forward these to the lookup nodes (another type of nodes) for distribution to the shards in the network. Seed nodes also maintain the entire transaction history and the global state of the blockchain which is needed to provide services such as block explorers. Seed nodes in the Zilliqa network are comparable to Infura on Ethereum.
 
The seed nodes were first only operated by Zilliqa themselves, exchanges and Viewblock. Operators of seed nodes like exchanges had no incentive to open them for the greater public.They were centralised at first. Decentralisation at the seed nodes level has been steadily rolled out since March 2020 ( Zilliqa Improvement Proposal 3 ). Currently the amount of seed nodes is being increased, they are public facing and at the same time PoS is applied to incentivize seed node operators and make it possible for ZIL holders to stake and earn passive yields. Important distinction: seed nodes are not involved with consensus! That is still PoW as entry ticket and pBFT for the actual consensus.
 
5% of the block rewards are being assigned to seed nodes (from the beginning in 2019) and those are being used to pay out ZIL stakers.The 5% block rewards with an annual yield of 10.03% translates to roughly 610 MM ZILs in total that can be staked. Exchanges use the custodial variant of staking and wallets like Moonlet will use the non custodial version (starting in Q3 2020). Staking is being done by sending ZILs to a smart contract created by Zilliqa and audited by Quantstamp.
 
With a high amount of DS & shard nodes and seed nodes becoming more decentralised too, Zilliqa qualifies for the label of decentralised in my opinion.
 
Smart contracts
 
Let me start by saying I’m not a developer and my programming skills are quite limited. So I‘m taking the ELI5 route (maybe 12) but if you are familiar with Javascript, Solidity or specifically OCaml please head straight to Scilla - read the docs to get a good initial grasp of how Zilliqa’s smart contract language Scilla works and if you ask yourself “why another programming language?” check this article. And if you want to play around with some sample contracts in an IDE click here. Faucet can be found here. And more information on architecture, dapp development and API can be found on the Developer Portal.
If you are more into listening and watching: check this recent webinar explaining Zilliqa and Scilla. Link is time stamped so you’ll start right away with a platform introduction, R&D roadmap 2020 and afterwards a proper Scilla introduction.
 
Generalised: programming languages can be divided into being ‘object oriented’ or ‘functional’. Here is an ELI5 given by software development academy: > “all programmes have two basic components, data – what the programme knows – and behaviour – what the programme can do with that data. So object-oriented programming states that combining data and related behaviours in one place, is called “object”, which makes it easier to understand how a particular program works. On the other hand, functional programming argues that data and behaviour are different things and should be separated to ensure their clarity.”
 
Scilla is on the functional side and shares similarities with OCaml: > OCaml is a general purpose programming language with an emphasis on expressiveness and safety. It has an advanced type system that helps catch your mistakes without getting in your way. It's used in environments where a single mistake can cost millions and speed matters, is supported by an active community, and has a rich set of libraries and development tools. For all its power, OCaml is also pretty simple, which is one reason it's often used as a teaching language.
 
Scilla is blockchain agnostic, can be implemented onto other blockchains as well, is recognised by academics and won a so called Distinguished Artifact Award award at the end of last year.
 
One of the reasons why the Zilliqa team decided to create their own programming language focused on preventing smart contract vulnerabilities safety is that adding logic on a blockchain, programming, means that you cannot afford to make mistakes. Otherwise it could cost you. It’s all great and fun blockchains being immutable but updating your code because you found a bug isn’t the same as with a regular web application for example. And with smart contracts it inherently involves cryptocurrencies in some form thus value.
 
Another difference with programming languages on a blockchain is gas. Every transaction you do on a smart contract platform like Zilliqa for Ethereum costs gas. With gas you basically pay for computational costs. Sending a ZIL from address A to address B costs 0.001 ZIL currently. Smart contracts are more complex, often involve various functions and require more gas (if gas is a new concept click here ).
 
So with Scilla, similar to Solidity, you need to make sure that “every function in your smart contract will run as expected without hitting gas limits. An improper resource analysis may lead to situations where funds may get stuck simply because a part of the smart contract code cannot be executed due to gas limits. Such constraints are not present in traditional software systems”. Scilla design story part 1
 
Some examples of smart contract issues you’d want to avoid are: leaking funds, ‘unexpected changes to critical state variables’ (example: someone other than you setting his or her address as the owner of the smart contract after creation) or simply killing a contract.
 
Scilla also allows for formal verification. Wikipedia to the rescue:
In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics.
 
Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code.
 
Scilla is being developed hand-in-hand with formalization of its semantics and its embedding into the Coq proof assistant — a state-of-the art tool for mechanized proofs about properties of programs.”
 
Simply put, with Scilla and accompanying tooling developers can be mathematically sure and proof that the smart contract they’ve written does what he or she intends it to do.
 
Smart contract on a sharded environment and state sharding
 
There is one more topic I’d like to touch on: smart contract execution in a sharded environment (and what is the effect of state sharding). This is a complex topic. I’m not able to explain it any easier than what is posted here. But I will try to compress the post into something easy to digest.
 
Earlier on we have established that Zilliqa can process transactions in parallel due to network sharding. This is where the linear scalability comes from. We can define simple transactions: a transaction from address A to B (Category 1), a transaction where a user interacts with one smart contract (Category 2) and the most complex ones where triggering a transaction results in multiple smart contracts being involved (Category 3). The shards are able to process transactions on their own without interference of the other shards. With Category 1 transactions that is doable, with Category 2 transactions sometimes if that address is in the same shard as the smart contract but with Category 3 you definitely need communication between the shards. Solving that requires to make a set of communication rules the protocol needs to follow in order to process all transactions in a generalised fashion.
 
And this is where the downsides of state sharding comes in currently. All shards in Zilliqa have access to the complete state. Yes the state size (0.1 GB at the moment) grows and all of the nodes need to store it but it also means that they don’t need to shop around for information available on other shards. Requiring more communication and adding more complexity.

Roadmap / Zilliqa 2.0
 
There is no strict defined roadmap but here are topics being worked on. And via the Zilliqa website there is also more information on the projects they are working on.
 
Business & Partnerships  
It’s not only technology in which Zilliqa seems to be excelling as their ecosystem has been expanding and starting to grow rapidly. The project is on a mission to provide OpenFinance (OpFi) to the world and Singapore is the right place to be due to its progressive regulations and futuristic thinking. Singapore has taken a proactive approach towards cryptocurrencies by introducing the Payment Services Act 2019 (PS Act). Among other things, the PS Act will regulate intermediaries dealing with certain cryptocurrencies, with a particular focus on consumer protection and anti-money laundering. It will also provide a stable regulatory licensing and operating framework for cryptocurrency entities, effectively covering all crypto businesses and exchanges based in Singapore. According to PWC 82% of the surveyed executives in Singapore reported blockchain initiatives underway and 13% of them have already brought the initiatives live to the market. There is also an increasing list of organisations that are starting to provide digital payment services. Moreover, Singaporean blockchain developers Building Cities Beyond has recently created an innovation $15 million grant to encourage development on its ecosystem. This all suggest that Singapore tries to position itself as (one of) the leading blockchain hubs in the world.
 
Zilliqa seems to already taking advantage of this and recently helped launch Hg Exchange on their platform, together with financial institutions PhillipCapital, PrimePartners and Fundnel. Hg Exchange, which is now approved by the Monetary Authority of Singapore (MAS), uses smart contracts to represent digital assets. Through Hg Exchange financial institutions worldwide can use Zilliqa's safe-by-design smart contracts to enable the trading of private equities. For example, think of companies such as Grab, AirBnB, SpaceX that are not available for public trading right now. Hg Exchange will allow investors to buy shares of private companies & unicorns and capture their value before an IPO. Anquan, the main company behind Zilliqa, has also recently announced that they became a partner and shareholder in TEN31 Bank, which is a fully regulated bank allowing for tokenization of assets and is aiming to bridge the gap between conventional banking and the blockchain world. If STOs, the tokenization of assets, and equity trading will continue to increase, then Zilliqa’s public blockchain would be the ideal candidate due to its strategic positioning, partnerships, regulatory compliance and the technology that is being built on top of it.
 
What is also very encouraging is their focus on banking the un(der)banked. They are launching a stablecoin basket starting with XSGD. As many of you know, stablecoins are currently mostly used for trading. However, Zilliqa is actively trying to broaden the use case of stablecoins. I recommend everybody to read this text that Amrit Kumar wrote (one of the co-founders). These stablecoins will be integrated in the traditional markets and bridge the gap between the crypto world and the traditional world. This could potentially revolutionize and legitimise the crypto space if retailers and companies will for example start to use stablecoins for payments or remittances, instead of it solely being used for trading.
 
Zilliqa also released their DeFi strategic roadmap (dating November 2019) which seems to be aligning well with their OpFi strategy. A non-custodial DEX is coming to Zilliqa made by Switcheo which allows cross-chain trading (atomic swaps) between ETH, EOS and ZIL based tokens. They also signed a Memorandum of Understanding for a (soon to be announced) USD stablecoin. And as Zilliqa is all about regulations and being compliant, I’m speculating on it to be a regulated USD stablecoin. Furthermore, XSGD is already created and visible on block explorer and XIDR (Indonesian Stablecoin) is also coming soon via StraitsX. Here also an overview of the Tech Stack for Financial Applications from September 2019. Further quoting Amrit Kumar on this:
 
There are two basic building blocks in DeFi/OpFi though: 1) stablecoins as you need a non-volatile currency to get access to this market and 2) a dex to be able to trade all these financial assets. The rest are build on top of these blocks.
 
So far, together with our partners and community, we have worked on developing these building blocks with XSGD as a stablecoin. We are working on bringing a USD-backed stablecoin as well. We will soon have a decentralised exchange developed by Switcheo. And with HGX going live, we are also venturing into the tokenization space. More to come in the future.”*
 
Additionally, they also have this ZILHive initiative that injects capital into projects. There have been already 6 waves of various teams working on infrastructure, innovation and research, and they are not from ASEAN or Singapore only but global: see Grantees breakdown by country. Over 60 project teams from over 20 countries have contributed to Zilliqa's ecosystem. This includes individuals and teams developing wallets, explorers, developer toolkits, smart contract testing frameworks, dapps, etc. As some of you may know, Unstoppable Domains (UD) blew up when they launched on Zilliqa. UD aims to replace cryptocurrency addresses with a human readable name and allows for uncensorable websites. Zilliqa will probably be the only one able to handle all these transactions onchain due to ability to scale and its resulting low fees which is why the UD team launched this on Zilliqa in the first place. Furthermore, Zilliqa also has a strong emphasis on security, compliance, and privacy, which is why they partnered with companies like Elliptic, ChainSecurity (part of PwC Switzerland), and Incognito. Their sister company Aqilliz (Zilliqa spelled backwards) focuses on revolutionizing the digital advertising space and is doing interesting things like using Zilliqa to track outdoor digital ads with companies like Foodpanda.
 
Zilliqa is listed on nearly all major exchanges, having several different fiat-gateways and recently have been added to Binance’s margin trading and futures trading with really good volume. They also have a very impressive team with good credentials and experience. They dont just have “tech people”. They have a mix of tech people, business people, marketeers, scientists, and more. Naturally, it's good to have a mix of people with different skill sets if you work in the crypto space.
 
Marketing & Community
 
Zilliqa has a very strong community. If you just follow their Twitter their engagement is much higher for a coin that has approximately 80k followers. They also have been ‘coin of the day’ by LunarCrush many times. LunarCrush tracks real-time cryptocurrency value and social data. According to their data it seems Zilliqa has a more fundamental and deeper understanding of marketing and community engagement than almost all other coins. While almost all coins have been a bit frozen in the last months, Zilliqa seems to be on its own bull run. It was somewhere in the 100s a few months ago and is currently ranked #46 on CoinGecko. Their official Telegram also has over 20k people and is very active, and their community channel which is over 7k now is more active and larger than many other official channels. Their local communities) also seem to be growing.
 
Moreover, their community started ‘Zillacracy’ together with the Zilliqa core team ( see www.zillacracy.com ). It’s a community run initiative where people from all over the world are now helping with marketing and development on Zilliqa. Since its launch in February 2020 they have been doing a lot and will also run their own non custodial seed node for staking. This seed node will also allow them to start generating revenue for them to become a self sustaining entity that could potentially scale up to become a decentralized company working in parallel with the Zilliqa core team. Comparing it to all the other smart contract platforms (e.g. Cardano, EOS, Tezos etc.) they don't seem to have started a similar initiatives (correct me if I’m wrong though). This suggest in my opinion that these other smart contract platforms do not fully understand how to utilize the ‘power of the community’. This is something you cannot ‘buy with money’ and gives many projects in the space a disadvantage.
 
Zilliqa also released two social products called SocialPay and Zeeves. SocialPay allows users to earn ZILs while tweeting with a specific hashtag. They have recently used it in partnership with the Singapore Red Cross for a marketing campaign after their initial pilot program. It seems like a very valuable social product with a good use case. I can see a lot of traditional companies entering the space through this product, which they seem to suggest will happen. Tokenizing hashtags with smart contracts to get network effect is a very smart and innovative idea.
 
Regarding Zeeves, this is a tipping bot for Telegram. They already have 1000s of signups and they plan to keep upgrading it for more and more people to use it (e.g. they recently have added a quiz features). They also use it during AMAs to reward people in real time. It’s a very smart approach to grow their communities and get familiar with ZIL. I can see this becoming very big on Telegram. This tool suggests, again, that the Zilliqa team has a deeper understanding what the crypto space and community needs and is good at finding the right innovative tools to grow and scale.
 
To be honest, I haven’t covered everything (i’m also reaching the character limited haha). So many updates happening lately that it's hard to keep up, such as the International Monetary Fund mentioning Zilliqa in their report, custodial and non-custodial Staking, Binance Margin, Futures & Widget, entering the Indian market, and more. The Head of Marketing Colin Miles has also released this as an overview of what is coming next. And last but not least, Vitalik Buterin has been mentioning Zilliqa lately acknowledging Zilliqa and mentioning that both projects have a lot of room to grow. There is much more info of course and a good part of it has been served to you on a silver platter. I invite you to continue researching by yourself :-) And if you have any comments or questions please post here!

[Suggestion] - Long time laptop user who's outgrown portability in need of power/multitasking

This may be a bit of a long post but I want to make sure I provide any additional context if it helps. If I can add any additional information, please just let me know!
For the last 10+ years, I've relied on a few different laptops. While I consider myself tech savvy for the most part, I haven't really needed my laptop to be a tank and I've gotten by for what I've done. This is mainly Office, and stuff in Chrome.
I used to have a Thinkpad with a dedicated NVIDIA GPU but aside from doing some really simple work in MATLAB, I didn't really take advantage of it...
For the last 4-5 years, I've had a Microsoft Surface Pro 4 and have enjoyed it overall. Now, during the quarantine, I'm rediscovering hobbies/interests I haven't really participated in like a decade.
I'm starting to use my Surface for a whole bunch more intensive tasks and my computer is starting to struggle.
The following categories are a summary of the types of things I've been trying to do or would like to do that my Surface just can't hack it anymore:
I don't think I need a dedicated NVIDIA GPU that's $5,000. But I also don't want to get the "wrong thing" and have buyer's remorse.
I'd love a "Jack of All Trades" kind of PC that will help me dabble in various interests. I don't necessarily need to run the latest games at 500FPS, mine bitcoin, or discover unknown prime numbers...
Any help would be greatly appreciated!

Great video on Bitcoin protocol development & philosophy

This was a discussion between MIT Digital Currency Initiative's Neha Narula and Lightning Lab's Elizabeth Stark that happened a few days ago about Bitcoin development. I think as investors/traders it's important for us to stay up to date on what is happening in the development of the tech in order to make good trading/investing decisions.
Here are the most significant quotes, in my opinion (most from Neha):
3:12 - On protocol development
I think that there are four key areas to think about when you think about what's happening in Bitcoin core and what kinds of updates are being made. I've been listening along this morning its been a lot about bitcoin as an asset and digital currency as an asset class. Now we're going to talk about it as a technology, which id what it was originally and what it always will be and what the asset class depends on. I think the key thing to remember with Bitcoin is that they're always trying to improve four key areas: Better privacy, which makes it harder to censor transactions. Better performance which makes it easier to run a full node and therefore makes the network more decentralized. Better robustness, making it harder to attack in general. And then, functionality.
4:32 - On development philosophy
Another big part of the philosophy I think and something that's driving a lot of the new functionality changes is we really need to minimize what goes on chain. So this is in pretty stark contrast to a lot of smart contract platforms which execute every step of every smart contract on chain. It's like you take the program you want to run, you put the whole thing on the chain. Bitcoin's going for a slightly different approach, that approach is let's do as little on chain as possible. [Stark asks where this originated from, if Satoshi had some of these ideas] Yea, I think whoever designed Bitcoin script was definitely thinking a lot about this. It comes from the fact that, A blockchain is replicated across thousands of nodes, and hopefully one day millions if not billions of nodes, you can't execute everything that way you gotta be really careful you gotta think about what goes on chain. I think that's part of the ethos, and that's where we see things like Taproot/Schnorr.
5:37 - On what Taproot/Schnorr is
6:43 - On the speed of Bitcoin development
Bitcoin development is a little slow, but the reason is because there's nobody in charge..and people care a lot about robustness and they really care about doing good code review and making sure that this stuff is solid before it gets in.
7:30 - More on the philosophy of development
The base chain needs to be as simple as possible and needs to have the hooks necessary to support higher level functionality, that's the idea. [Stark comments on not having the complexity in the middle of the network]. We're building bitcoin to be around for centuries. The idea here is you put as little as possible into that base layer. You don't want to involve the base layer, you don't want to be constantly be re-writing the base layer. You want to have a base layer that is really, really robust. Something we've seen a lot is complexity is really the enemy of security. If you have a very complicated protocol, if you have really complicated functionality, guess what? That's a huge attack surface. The whole point of this technology is to be secure. We're removing the trusted third party, we're relying on cryptography and software and so that really needs to be secure, and sometimes I just think people do not take that seriously enough.
10:07 - More on the philosophy of development
We are building software that is supposed to run for a very long time. If there's anything that I can tell people about today, it's to tell them about this philosophy, this mindset of trying to build software that is super robust. And that's sort of the interesting thing that have been happening in Bitcoin development too, like one big change is removing code. They removed openSSL which is a library for a lot of cryptographic function and this was super celebrated because a third party library is a source of bugs, a source of consensus failure, people have different versions on their machine. So removing this was a huge win, actually. Makes the network more secure.
11:07 - On mainstream adoption and what that means
13:20 - On funding open-source development
15:21 - On the Lightning Network (goes until end)
Side note: In my opinion, this is one of the reasons why Bitcoin has and will continue to succeed: there are word-class developers and scientists improving the protocol. I mean, just look at these people's fucking pedigrees:
Stark previously taught at Stanford and Yale University about the future of the internet, and was a visiting fellow at Yale’s Information Society Project...She has advised startups ranging from decentralized technology to AI and was an entrepreneur-in-residence at Stanford StartX. Stark holds a J.D. from Harvard.

BetFury recommends: crypto movies for a fun pastime

BetFury recommends: crypto movies for a fun pastime

https://preview.redd.it/fc4tsrf1aev41.png?width=1260&format=png&auto=webp&s=bbd65ae18a5a4d1e1ff0be3342de6039fe7cd23e
News hooks in the media, movies, series and even tracks of famous rap artists are increasingly mention about bitcoin, blockchain and other definitions beloved by our hearts. Due to the current situation in the world, many users are quarantined and look for interesting things to watch. We have compiled an interesting, in our opinion, list consisting of movies, series and cartoons that speak of cryptocurrencies (and a little bit about gaming).

1.“The Bitcoin Entanglement” — The big bang theory S09E11

We should pay tribute to the creators of the series — they spoke about cryptocurrencies, firstly, in a simple language, secondly, it is absolutely correct. Year 2010. Sheldon is at the comics book store: Oh, Stuart, hello. I would like to clarify — will you accept bitcoins? Stewart: Well, I don’t know what it is. But it sounds better than nothing, what my box office consists of. So yes.

In general, if someone asks you in a nutshell to tell what bitcoins are, recommend to watch the S09E11 TBBT series.

5. Dope

https://youtu.be/9LHhewmvO1I
A movie about currency frauds perverted by teens is a must see, even if you’re not interested in the world of crypto. But cryptocurrency has played a major role since the beginning of this movie. The protagonist, Malcolm, says, “There’s nothing left to do but just look at the money, because we know perfectly well that they are worthless.” He predicts that soon people will only use bitcoins. Dope is also the first movie to be screened for bitcoin tickets.
Take a big bucket of popcorn, turn on your favorite movie and enjoy. Discover the cryptocurrencies in an entertaining way. Wrap up in the world of crypto and gaming. Sure, you’ll find something new and interesting you’ve never known.

Improving the standard of living and securing a better future through Digital Gold investment

Improving the standard of living and securing a better future through Digital Gold investment
Living, all by itself, is a struggle when one is out of a vocation however it's more regrettable when one resigns without something considerable to appear for it, work is burdening wellbeing astute and work shrewd and time-wise, so one gets ready for mature age and retirement with different plans and approaches, some look to put resources into treasury securities, common assets, stocks, new businesses, land and so forth yet just a couple really get the opportunity to have advantageous ventures.
Contributing is mind-boggling, one is confronted with the difficulties of data and the alternative of browsing plenty of speculation choices

Gold is a benefit known to man more than a great many ages, Gold and copper were the principal metals utilized by people beginning from 5000 BC, The main enlisted gold found in the US was a piece weighing 7.8kg found in Cabarrus County, North Carolina. At the point when progressively gold was found in little spring glade in 1803, the primary US dash for unheard of wealth started. The world's biggest gold hold is held five stories underground in the vault of the Federal Reserve Bank of New York, it contains 25% of all the gold saves in the world(540,000 gold bars), the greater part of them have a place with remote gov't. The main ever gold candy machine was introduced in Dubai in 2010. Because of its irregularity and high worth, a large portion of the gold at any point mined is still in flowing gold was removed over the most recent 100 years. Numerous individuals inquire as to why gold is so costly, the explanation is its irregularity: more steel is delivered in one hour than gold through the span of the whole mankind's history. Numerous researchers accept that gold is likewise present in Mars, Mercury and Venus.
Reports state China is expanding its gold imports and Mark Mobius, an energetic broker in gold has prompted that individuals buy gold, he accepts that the cost of gold will continue developing as the measure of paper cash in the worldwide economy increments.

Do you realize that under 82% of Americans own any bit of gold?
The exchanging volume of advanced gold is over $100 million
Do you realize you also can put resources into gold?
We should discuss the potential outcomes of putting resources into gold utilizing a blockchain stage, you should have one bit of gold that has a token portrayal,
The explicit explanation on the advanced gold token, what it does and how you can really profit by it.
Presently, in the event that you are following intently, you will find that the crypto showcase hit its top in 2017, in 2017 bitcoin was selling for $20,000 and in 2020, it is coasting around $9,000 and each genuine speculator ought to be seeing this market, at 2017 the complete market capitalization of digital forms of money was nearly $1 Trillion dollars and however it has tumbled to around $300 billion dollars in 2020, this industry despite everything holds a ton of possibilities.
One ought to inquire as to for what reason is there so much venture going into the blockchain space, what is the potential that this thing has, many have named blockchain as web 3.0 or a definitive innovation that will introduce web 3.0, till date, the speculations that have experienced different blockchain new businesses have been over $25 billion dollars with any semblance of EOS, Telegram raising billions of dollars each.
What are the issues associated with putting resources into cryptographic forms of money?
1.Volatility: If you take a gander at the altcoin unsurpassed record, you will see the sickening drop in crypto esteem
What of tasks that have lost over 10000% of their incentive over the course of about two years.
  1. Storage: Knowing which coins to buy and how to store them is a major problem in the digital currency world,crypto-jacking and hacking are at the untouched high as programmers have invaded most internet browsers with coin mining contents and simply a year ago over $1 billion dollars worth of crypto resources were taken from a few trades which thusly constrained them to close their entryways.
To store crypto resources, one is required to safely keep their passwords and their hidden keys as the loss of them mean lost access to their property.

Tokenization
The thought is planned for breaking entire units of stocks, foundation and so forth into littler pictures.
Take one unit of gold and make an advanced unit of it with the blockchain, that thought really birthed the Digital gold token project.
The computerized gold commercial centre: encourages a generally simple, powerful and proficient buy/deal framework, clients can just round out a structure that starts a brilliant agreement, which at that point moves the recently printed GOLD tokens.
Concerning engineers, they are additionally spared the issue of the complexities that accompany coordinating a crypto resource for their foundation, the advanced gold tasks assist them with incorporating without any problem.

Highlights of Digital Gold
The advanced gold token flaunts various highlights that make it one of a kind and beneficial for potential speculators to investigate.
It's a token that is minimal effort and doesn't have move costs when one is moving it, it offers potential speculators the chance to broaden their portfolio while additionally keeping their riches in a place of refuge, it likewise gives secure gold possession as the bought gold is made sure about in a sheltered vault, the computerized gold token is exceptionally fluid, which means there is a business opportunity for you at whatever point you expect to sell or purchase the token since the advanced gold token is attached to real gold, the token is as significant as gold itself, so as gold increments in esteem so does the token.

Time for some to move on...

I support the funding proposal... Of course I have my personal doubts, see potential red flags, and still need to fully comprehend how this can all play out...
But I believe it's time for BCH to start fulfilling its potential. And the strong commitment indicated by 4 of the biggest names in BCH, will bring great benefit to Bitcoin Cash imo...
It can go wrong of course but I believe the potential upside is factors greater than the worst case doomsday thinking I see everywhere now...
It's funny how suddenly the ''Evil Chinese Miners'' talking point is back...Which brings me to my following point:
I am for this proposal, many of you are against it... It makes it hard for me to read correctly into all of your worries, as effectively you are standing shoulder to shoulder, screaming with Corebois, SVtards and other BCH haters, who are just here to create as much sabotage, distrust, chaos as possible...
The commitment signaling from Bitcoin.com and the Chinese is obvious; they will go ahead and commit 110% to making the fund happen...
So at this point if you are truly not able to digest what is coming; it might be time for you to drop your support for BCH.. Alternatively you have about 100 days left to convince the community to abort, or of course you are free to launch a hash war for control....
It's ok... I understand the fanatic positions to rather see BCH dwindle into oblivion (and feel proud still), then to make a single trade off that is needed to guarantee long term survival and thriving of the chain... It's an emotional battle we are all having to an extend...
But the simple truth is that everyone here had 2.5 years of undisturbed momentum to build up BCH in its most perfect and puritan form, engage in community building, write up proposals etc etc etc... And to be clear, many community members have done amazing things since aug 2017...
But sadly the fact is, the tragedy of the commons did hit BCH, and certain problems are just not going to solve themselves... and without action and a solution, this project can easily end in an irreversible and definitive failure...
If I have the choice between being a moral knight and turning my back on BCH, or accept the trade off... I will stand with the proven track record of Roger's, Jihan's and Haipo's integrity and love for BCH.
The Bitcoin Cash train is moving on, onto world domination, globally mass adopted as P2P cash... And Im not gonna leave myself behind...
So make up your mind..
P.S. We can all complain about everything not being picture perfect, but in the end the hashing machines decide... And they have announced their decision...
If I had to post one suggestion; I would like to see a Pledge from the 4 gents, to not proceed directly after these 6months, with a second 6 month term... Lets keep this TRIAL AND ERROR, as a first attempt
Let's use the nov20-may21 season to evaluate the 6 month period; examine and analyze usage of the funds... address the % in case BCH price goes up substantially... and eventually agree if we should do this again may21-nov21, do it in an amended version, or stop doing it all together..
Thanks for all of your participation, and hopefully we will come through unified and stronger

Recap of Chromia AMA with the CEO of Chromia, @henrik_hjelte on BithumbGlobal telegram community dated 14.04.2020.

The AMA was moderated by u/Sidonpee.
Sidonpee
Let’s start with the introduction question:
u/henrik_hjelte Can you introduce yourself to the community? What is your background?
Henrik Hjelte
I’m the CEO of ChromaWay, the company that started the Chromia project. My background is 30+ years as a developer (got payed first when I was 15), then studied Business and other things (politics and philosophy). Worked as Finance and IT consultant. THen wanted to be an entrepreneur. started a “web 2.0” startup about a free-speech internet. Hired our current CTO as a developer. THen joined his colored-coins project, the first token protocol ie the start of blockchain in 2012.
Sorry. I’m now 50 years old, the math didn’t add up. That is why I’m the CEO and not CFO.
Sidonpee
Q1. What is Chromia? Can you tell us the technology behind it and the features that makes it unique?
Henrik Hjelte
Chromia is a new public blockchain based on the idea of integrating traditional databases, “Relational databases” with blockchain security. In the normal world outside blockchain, there is one technology that is in 100% of all enterprises and powers almost all webpages. It build Facebook, SAP, banks, blogging platforms. It is the relational database, or SQL database. Has been used for 30+ years and is still dominant with 85% market share. Why are people using it (NoSQL has been around for 15+ years)?
Because it is the best way of managing data known to mankind. Now what is blockchani? It is a way to manage data that is shared. So if you agree that blockchain is about managing data, a relational database should be an obvious technology. Chromia is a general purpose blockchain with full smart contract capabilities, just that it is a lot easier to code, even complex applications. You code with an easy to learn new programming language that combines the power of SQL and “normal languages” but makes it secure in a blockchain context. Up to 1/10 the code-lines vs other blockchains.
Sidonpee
Q2. I often see Chromia and ChromaWay being used interchangeably, what is the relationship between the two?
Henrik Hjelte
The idea for Chromia and parts of the codebase originated from the company ChromaWay. It is actually one of the first blockchain companies, we had a project for tokens before ethereum called the “colored coins” project that led to us starting a company with a name take from the greek word for color. In 2015 we did what is now called stable-coin, EURO payments based on tokens on a public blockchain (tokens on bitcoin). It was for a bank LHV in Estonia. When we need to quickly find information, we could not search the blockchain and instead started to dump everything to a relational database, and then the idea started to grow to build a blockchain around this. So we did a private blockchain, intended for usecases in land-registration, banking and more. And then came up with the idea of doing a public blockchain for it.
ChromaWay is the company that ideated Chromia and provided the first open source code for it. The Chromia pre-sale of tokens is now funding the development of Chromia, which is done by ChromaWay. When Chromia is released as a decentralized network, it will not be governed or run by ChromaWay. Of course we know it has to be decentralized, we understand the virtues of decentralization since 2012 when our CTO did the worlds first code for tokens, then started an open-source project which even inspired Vitalik (who soon quit and did his own thing). ChromaWay as a company will take a role as providing optional support and maintenance of Chromia projects (open for competition by other players).
Sidonpee
Q3. What’s the usefulness of $CHR token in Chromia ecosystem?
Henrik Hjelte
CHR can be used to pay for running dapps (normally by the developer of the dapp, not users). It can also be used as a mean of exchange between dapps, and to provide collateral/stake for providers (the ones running the blockchain), incentivizing good behaviour.
Sidonpee
Q4. What are the major milestones Chromia has achieved so far & what are your plans for 2020?
Henrik Hjelte
We have released Rell, the new programming language that is needed, and supported tooling (online Development Environment, downloadable IDE, documentation). We have release the first testnet in december, and at the same time another company 4irelabs has done the first dapp running on testnet. They could take our old code (done as a private blockchain), learn our new language Rell and port it to Chromia. That project is the Green Assets Wallet, green bond environmental impact reporting, run by a non-profit and with banks and institutions as users.
Plans for 2020 is to both release a series of dApps to showcase how fantastic Chromia is, as well as continue to develop the platform. And when it is secure and good enough, we will release mainnet.
Dapps are now being made by us as well as others. We do a decentralized social network framework call chromunity, now release to testnet. If is really cool, users can vote over moderators, and in the future users might even govern the complete application, how it can be updated. This is a great showcase for Chromia and why we use the slogan Power to the Public.
Games coming are….
  1. Mines of Dalarnia (by Workinman Interactive). An action game in a mine with blockchain rental of plots and stuff.
  2. Krystopia 2, novas journey. A puzzle game done by Antler Interactive.
  3. An indie game (not done by us so I don’t know how much I shoiul;d menton), but: it is a strategy game with FULL-LOGIC ON BLOCKHCHAIN yes ubercool that is why it is in caps
  4. A secret demo-project that we do together with Antler to showcase the technical potential of Chromia platform.
More comin in 2020: Other dapps from other companies, one in impact-tech
Games is a great way to show scalability and features BTW.
I didn’t mention that Chromia is very scalable (everyone says that). But it is true, and with no tradeoff vs decentralization
well, but I can also see enterprise projects going into more of public blockchain direction and hybrid, and there I think Chromia can really shine
Sidonpee
Q5. Revenue and adoption are the main points of all projects, can you tell us your Business model and how you generate revenue?
Henrik Hjelte
Chromia itself is a public network with no intrinsic business model, but participants in the network has. For example Providers make money from supplying quality hardware running dapps and the core software, dapp developers have individual business models.
I already told about about ChromaWay/Chromia, but ChromaWay the company can provide support/maintenance and various services and add-ons for Chromia. It is very similar to how normal open-source vendors make money.
Still up to competition from others, and without control over the Chromia network. We need it to be independent, otherwise it has no value.
So it is sound business to have it decentralized as well, who would care otherwise?
Sidonpee
Q6. Regarding Chromia’s blockchain game (Minesofdalarnia), I’m quite sure that vast majority of game lovers would be anticipating for it release, could you please share with us the likely date it will be released?
Henrik Hjelte
Yes I can
We have made very good progress recently, and I can happily share that MoD is planned to be released now in Q2.
Anastasia
Meanwhile you can check the Mines of Dalarnia Social Media page for recent updates on the game https://twitter.com/Chromia_Studios . We publish development updates there often.
You can also sign-up for early access on https://www.minesofdalarnia.com 😉
Sidonpee
Q7. Recently Chromia welcome Malcolm Lerider who was formally a Senior R&D Manager for Neo Blockchain as its new team and family member. When he was with Neo, he worked together with the community and was able to build the project from a top 50-something market cap project to a top 5 market cap project. Should we be expecting a replica of this at Chromia in the nearest future?
Henrik Hjelte
Yes. we are very excited to have Malcolm on-board, he is very knowledgeable in the area, and his expertise will definitely help with achieving that. Malcolm recently published an article where he introduced himself as a new member of Chromia. You can read it over here, if you haven’t already: https://medium.com/@MalcolmLeridei-am-joining-team-chromia-b25d527b5b6f
Sidonpee
Q8. Green Asset Wallet is absolutely an amazing starter in the Chromia blockchain! I would like to hear how you guys see the future business development possibilities in the next /6/12 months? Are there specific business areas, geographical locations, which you want to focus on most?
Henrik Hjelte
Thank you, yes, it is nice to have a project that is enterprise, and green too as the first one.
We are working both to reach out but also support inbound requests for projects, I shared some above.
Sometimes with business development, ChromaWAy might find a customeprospect but we don’t know where it will end. We think however, and Gartner too, that enterprise blockchain is gradually looking more at public blockchain projects.
I think DeFI, tokenization of assets and things like that is interesting.
Also, hopefully someone will be inspired by our solution to a free, open, user-governed decentralized social web, what we are now showing with Chromunity. Jack Dorsey, are you listening?
We don’t have a particular geographical focus though, and really it is a generic platform use-case agnostic.
We use games to show potential and scalability, but who knows maybe other applications will be more. It is not only up to us.
Sidonpee
Q9. Who are Chromia’s strategic investors and partners? What criteria/ process do you follow in evaluating your partnership deal with them?
Henrik Hjelte
We have some strategic investors and partners that have helped us during the way, I think maybe I should not mention them here with the risk of forgetting some of them, and I have no time to check if we should mention them, We (and the partner) look at how we can help each other on a case by case basis. There is no simple scorecard that we can follow.
We try to avoid vanity partnership deals with no real meaning
Sidonpee
Q10. Why did Chromia develop a new language called Rell (Relational language) for dapp
programming?
Is the development of this new language really necessary?
If yes, what are some of its unique features that cannot be found in other existing languages/environments?
Henrik Hjelte
Yes it was necessary. We need the features of relational alegbra. It is is a mathematical basis, very similar to logic, that has only had basically one implementation (SQL). But SQL was not secure enough and lacked features that can be used in a shared context like a blockchain. Everything needs to be secure. Also we wanted to add blockchain features, and make it look more like “normal programming”. Now some of the readers might ask? Can’t you do this on the EVM? No. Ethereum does simply not have anything similar to a relational database, and it would be technically infeasible.
Some others may ask? How can you compete with the EVM /pet-project that have soo many developers etc…?
My answer is : we are building on top of a virtual machine called Postgresql. Check how much time, optimization and money has been spent on that virtual machine…
I think it is 20 years or more of development time, maybe more.
Static typing is one feature we add that SQL doesn’t have (you can detect bugs at compile time)
Yusuf
What have been the major obstacle Chromia has faced in the past years while developing its idea?
Whats the benefits for developers at Chromia? Why should we use Chromia instead of your competitors?
Henrik Hjelte
Obstacle: Technology/software developement is hard sometimes, difficult to predict when things are ready.
Major benefits for developers: A LOT EASIER to code COMPLEX applications. I’m serious. If you are frustrated with blockchain development, take a look at the ease of use of Rell/Chromia
LA LA
DeFi is projected to buzz up in 2020 and is on everybody lips, what ROLES does Chromia play in the innovativeness and future of DeFi and how does it spearhead adoption of DeFi using blockchain solution?
Henrik Hjelte
Finance would be almost unthinkable without relational databases, the power core banking and more. An exchange is a table of bid and ask, and you match them. This is very easy to do with our tech.
Sujit
If any Dapp is created on Chromia Blockchain! Then is there any Gas fees charged by Chromia? Whats the concept of fees for Dapps on Chromia Blockchain?
Henrik Hjelte
No gas per user fee. The application pays for hosting, like a cloud. Normally the developer, unless the developer hands over the governenace of the application to someone else (maybe the users).

Mayowa
Most blockchain projects have donated to COVID-19, but no news from Chromia. How will you contribute to fight COVID-19?
Henrik Hjelte
I had to answr this: I spent my free weekend time on a covid-19 hackathon the other week to do a solution to share medical equipment across countries. It is on our facebook I think u/anastasiazudina maybe you can share
Anastasia
We want to do our part for the ongoing covid19 crisis. Therefore, we were participating in the critical initiative HackTheCrisis. During the virtual hackathon, we tried to find good solutions for the new unique challenges that we now as a society are facing. https://www.facebook.com/chromaway/posts/2171037456376083
Mayowa
Chromia creates a new lightweight programming language called RELL. How is this different and better for programmers than other popular language like Solidity, C++ and Java?
Henrik Hjelte
When you think about a large Java project done for say a bank. Ask the developers what OTHER thing they use? DO they ONLY use Java and store files on a server? Or do they also use a database. You will find that in 99.9% of cases they ALSO use a relational database. No one would EVER think about doing a solution to manage data with ONLY Java, C++ or whatever.
Alejandro Urich
For the development of the Dapps, do you only support Rell? Is it possible to program in another language that works with Chromia?
Henrik Hjelte
Because we require both relational database properties and more security than SQL, currently Rell is the only choice. It is really easy to learn, and in all cases if we allowed a “normal” language it would miss the feautures of relational databases.
zafer metin
Mr Henrik What are the advantages of Postchain used for Chromia? How is a consortium provided to database management with distributed control?
Anastasia
Thank you for your interest in Postchain uses! We have an article written what answers exactly those questions: https://blog.chromia.com/postchain-for-the-public-scaling-relational-blockchain/
Stay At Home
As I know providers will be chosen by Chromaway, so how is it decentralized due to choice is totally in Chromaway?
Henrik Hjelte
Initial providers. We will migrate to a model where ChromaWAy has no more say than anyone else. But we need to bootstrap and start. Better to choose good initial providers.
David Prince
What is your long-term vision about the industry which Chromia is working at? Are you afraid someday there will be another Project with more innovative technology can replace Chromia?
Henrik Hjelte
Well. Blockchain is about managing data (in a shared context). I’m repeating myself but the market leading (85%) for 30+ years slution to manage data is a relational database. We are now the only relational database + blockchain. Who knows, maybe some better way to manage data will be invented? But even NoSQL who has been around and bark like a little dog has after a decade or more time only 15% market share. I think our tech will stand the mark of time.
Sidonpee
The AMA session with the Chronia team has finally come to an end.

What is Bitcoin? Bitcoin Explained Simply for Dummies What is Bitcoin? (v1) Bitcoin and the Coming Tutorial - How To Bitcoin for Beginners New Bitcoin Mining Site 2020  Free 100 GHs  Crypto Allies NP

If you still can’t figure out what the heck a bitcoin is, this simple explanation for a five-year-old may help you … We’re sitting on a park bench. It’s a great day. Bitcoin is the first decentralized digital currency. All Bitcoin transactions are documented on a virtual ledger called the blockchain, which is accessible for everyone to see. Bitcoin gives you complete control over your money, unlike other assets you own which are regulated by banks and governments. Crypto is by definition a token and by design encapsulated on a ledger. To say a bitcoin is not a unit of account is to say an abacus is not a calculating machine. Bitcoin and cryptocurrency is money. A Bitcoin transaction has, broadly speaking, the same three components. Each Bitcoin user stores the data that represents his or her amount of coins in a program called a wallet, consisting of a custom password and a connection to the Bitcoin system. The user sends a transaction request to another user, buying or selling, and both users agree. Bitcoin is a new currency that was created in 2009 by an unknown person using the alias Satoshi Nakamoto. Transactions are made with no middle men – meaning, no banks!
