Brief Comments on Goguen: Q4 2020, Q1 2021, utility, Marlowe, DSL, Glow, Plutus, IELE, smart contracts, thanksgiving to you, sidechains and Hydra, Goguen rollout and additions to product update

Smart contracts (origins in 80s, 90s vs. 2013 ETH and 2020s Cardano)
We had a pretty interesting product update. We laughed, we cried, we all learned a little bit. Two and a half hours lots of stuff and I hope this gives you guys a good window into all the things that are happening. There's an enormous amount of complexity in Cardano and Goguen is no different. In fact that one slide showing all the interlocking dependencies and the moving pieces for it and just the sheer volume of things that are going on is, is an indication of not only the quality of the team but also the commercial reality of being a smart contract platform. In 2020 when I co-founded Ethereum our reference material was paper. We looked at things that Nick Szabo and people from the 1990s and 1980s wrote about and whether you were a Ricardian contract fan or you had programmed in Eiffel or you understood things like FpML basically it was an open field which gave us kind of a freedom to just do whatever we wanted to do but it also didn't give us a commercial reality of who's going to buy it? Who's going to use it? What do you need to do? The expectations in 2020 are vastly different from the expectations in 2013 and the reality is that there are massive deficits with Ethereum as designed today which is why Tezos exists and Algorand exists and why ETH2 is being constructed . It's why there are so many different players from Polkadot and others on down who have deep and detailed opinions about the things we need to do. If the ICO revolution hadn't happened, there was no notion of an ERC20 token and we were in a just different world.
We didn't have DeFi, any of these things and now in 2020 if you are to be competitive and build great things and actually invite real use and utility at a scale of millions and billions of people or government or Fortune 500 you need to have real good answers about a lot of different threats and things. For example, Marlowe, what it does is it leverages 20 years of history from domain experts like Willi Brammertz and over 30 years of history in domain-specific language (DSL) design from professor Simon Thompson and his team and it puts them together. It says for the first time ever we're going to have semantical clarity between the entrepreneur, the developer, the writer and the financial services infrastructure whether that be the banker, the insurance agent, the exchange, whoever that might be. Up until the totality of human history till today we have never had that semantical clarity. All four of those actors speak different languages and what we're doing with Marlowe as a DSL is an example of how you can unify and create a common language and experience between all of them today.
Marlowe, DSL, Glow, Plutus, IELE
Right now, you guys can go to the Marlowe playground and you can start using it and start building things and start having that semantical clarity and work with us and over a period of six months or so that will continue to evolve. Templates will evolve, applications will be constructed and those applications will work their way into Cardano applications and eventually they'll become cross-platform and work on things like (Hyperledger) fabric and other such things as we see industry and commercial adoption but it requires a starting point and Marlowe has evolved over a four year period through the hard labors of so many people to actually give us a great starting point. You can visually look at contracts and talk about their design. You can write them in JavaScript, you can write them in the Marlowe programming language. There's a Haskell side to things and you can see the power of this approach because of its design. You can prove things are correct, you can use theory that has existed for over 40 years like SAT solvers and reachability to actually show that you're not going to have a parity bug and that's just one example of one DSL of which many more will come. The point of DSLs is to give clarity to people in the industry. For example if we get into the health business and we start talking about medical records that will become a DSL to broker their movement and that same clarity and semantical unification will occur between doctors and hospitals, patients, governments, regulators and business professionals and they will now have a common language. So, Marlowe is an entry point and it's an example of how to build a DSL and evolve a DSL and bring the right people to the table.
When we look to things like Glow, from MuKn, this is an example of a team that's highly motivated and intrinsically across blockchain. When we look to the future and we say what happens when Bitcoin gets smart contracts? What happens when ETH2 comes out? What happens when people want to build cross-blockchain applications? Wouldn't it be nice to have a unification language and that's what Glow is basically all about. By strategic investments in that ecosystem, what Glow does for us is it ensures that we won't be left behind that Cardano has that and all Cardano infrastructure can benefit from that and Glow in turn will benefit from its embedding in our ecosystem. More users, more technology and ultimately because Cardano's the best. If you deploy in that direction it's the best experience. When you look to Plutus, Plutus is the unification language, it's the conductor of the orchestra and it pulls all of these things together and there were a lot of design requirements with Plutus that were quite hard from a theory viewpoint. We really cared a lot about resource determinism. We wanted to make sure that it was always predictable or at least as predictable as it can be to know how much it costs to do things because at the end of the day this is not a science experiment. These are not toys back in 2013. We had the luxury with Ethereum of just seeing what happened and the market makes strategic investments and they have to know how much their operating cost is going to be for their business model. We designed Plutus so that it would be one of the best programming languages on a long arc agenda of being a very practical on and off chain language to unify all the Cardano ecosystem. There are many objects in the ecosystem to operate, manipulate, instruments of value like native assets, identity, smart contracts onto themselves, DAOs, off chain infrastructure and you need a conductor that's capable of living in between all of these things and you need certainty that the code you're writing is going to work.
This is why we based it on an ecosystem that has 35 years of history and we as a company have invested millions of dollars in that ecosystem to modernize it and bring it into the 21st century especially for things like Windows support and working with partners like Tweag WebAssembly support, working on projects like compilation to JavaScript so that we can share that's there and our commitment is going to continue beyond that we are a founding member of the Haskell foundation working with Simon Peyton Jones and we're going to ensure that Haskell has compilation to ARM and that all of the technology that's required to keep that language competitive and actually make the language even more competitive will happen. It's very nice that Plutus is deeply ingrained in that ecosystem and that makes it a perfect conductor language. In the coming months we're going to talk a lot more about our relationship decay in IELE. If you live in the imperative object-oriented world and you want to do things a bit differently than the way things are done in the Haskell functional world then it makes sense to have an option that has the same principles as us which is why we reached out to Grigore years ago and established a commercial relationship with him. It's been the privilege of my career finding a way to resurrect that relationship so in the coming months we're going to talk a lot about how IELE fits into the Cardano ecosystem and the value it's going to bring in addition to the value of Marlowe, Glow, and Plutus.
Native assets
One of the single most important things about all of this is the native asset standard. One of the things we did not anticipate when we created Ethereum is just how pervasive the user's ability to issue an asset would be. We figured this would be an important thing, it's why we put it on a T-shirt back in the Miami conference in January of 2014 and we realized that from the color coin's project in the master coin project and one of the most important things is that we have the ability to issue not just a utility token but non-functional assets, security tokens and a litany of other instruments that hold value. Some ephemeral, some permanent, some with flexible monetary policies, some with fixed monetary policies, some from a central issuer, some from a decentralized issuer, some managed by a foundation, some managed by the community, some managed by fixed code that's immutable and the point of the native asset standard in the ERC20 converter is to establish a co-evolution of the technology and the commercialization of the technology. What we've been doing with ERC20 converter is using that as a way to create a conversation with those who want to migrate or build on Cardano and thinking through how are we going to create practical standards with our native assets. We already have enormous advantages with this standard over Ethereum. In particular the fact that your assets you issue on Cardano are treated the way that ADA is treated whereas in Ethereum you're a second-class citizen or ETH is treated differently from smart contracts. This first class citizen approach means that your assets will have the same governance access layer, to portfolio access and infrastructure that ADA itself has. Easier listing experiences, easier time with hardware wallets, easier time with wallet software. In general better user experience, faster transactions, lower transaction costs and then eventually for higher value tokens even the possibility of paying transaction fees over the long term in the native asset itself as if you were your own cryptocurrency.
Goguen rollout
You just simply cannot do this with the design of Ethereum and Ethereum 2. It's a huge advantage we have in our ecosystem and it's one that will become more pervasive over time now Goguen has already started. As a launch agenda the very first update to enable some Goguen era functionality was the metadata standard which meant that you could go from just moving ADA around to actually a whole litany of applications in the identity space and in the metadata space some of which we're aggressively negotiating on in commercial deals which we'll announce at a later date. The rollout of Goguen in terms of the system as we mentioned in the presentation will be principally done for the first iteration over a series of three hard fork combinator (HFC) events. The first of which is beginning this year in November December time frame and that's going to lay a lot of the foundations that will enable us to get to the second hard fork combinator event which will occur in Q1 of next year and we'll announce that specific date likely at the next product update and then the third one will happen shortly thereafter. They have to be spaced this way because it's just simply too cumbersome on our developers and also our partners such as wallet infrastructure and exchanges to try to do too much too quickly and furthermore there's an enormous amount of work as you've noticed on that slide to roll out Goguen. You have to do two things at once, you have to deploy the infrastructure but then you also have to populate the infrastructure and what's nice about the way that we've done things as you now see with the Marlowe playground the population of that infrastructure is occurring now today and with the ERC20 converter and the mint test net that's coming.
That's going to occur in November which means that that gives people time to start building and playing on our ecosystem in a safe sandbox so that when they deploy it to the mainnet they do it right the first time and they don't make an existential failure as we have seen with the DeFi space because at the end of the day once you go live you have a huge adversarial surface and everybody in the world is going to try to break the things you've done. It's very important that you do it right which means that you need time as a commercial partner and an application deployer to do it correctly. Parts of Goguen are indeed shipping this year, some have already shipped and we'll have another HFC event at the end of next month or early in December and throughout the first quarter of next year and likely the second quarter will complete the other two HFC events which will roll out full support for native assets, extended UTxO, the Plutus infrastructure and the Marlowe infrastructure. In the meantime we're also working on strategies about how we can ensure best integration of Glow and IELE into the Cardano ecosystem and as you've noticed there are three parallel teams that are working very hard. The Shelley team continues to upgrade the Shelley experience. Just today we've received a lot of concerns over for example the state pool ranking in Daedalus. Let me be very clear about something. There's no problem with the ranking software, the problem is the k parameter. It needs to be increased and the fact that things are getting grayed out is an indication that the ranking parameter is actually working right for the first time. So, k needs to go up but there are consequences of that and we need to improve the software to reflect those consequences but it is my goal to get k to 1000 before ideally d hits 0 because we really do want to have over a 1000 well-functioning stake pools but by no means is that the end of the story.
Improvements + project Catalyst
We need partial delegation and delegation portfolios. We need means for stake pool operators to communicate effectively and efficiently with those who delegate to them. We need improvements in SMASH. We need an identity center, we need a litany of improvements to Daedalus itself. Right now, today, there are more than four companies working full-time at doing just these things in addition to the Goguen updates that are occurring right now. That research thread and that development thread will continue. We've already seen seven CIPs including CIPs related to the reward function. We take them very seriously, we review them and there's enormous amount of discussion about how to create a fair and balanced system and we appreciate this feedback. It's a process and we ask for patience and we also remind people that we launched Shelley just at the end of July and despite that the ecosystem has more than doubled in size and it's been growing at an incredible pace and it's only going to continue and we're only going to see our best days ahead of us. Good things are coming down the pipe and it's becoming a much more holistic ecosystem from in performance improvements, to usability improvements, to better overall software for everyone.
There's no greater example of that than what we've been able to accomplish in the last three months for the exchanges in general. We're really proud of what we've done with the Adrestia stack and we're really proud of working with great partners like Binance and Bittrex throughout the last few months and we've had some certain challenges there but as a result of overcoming those challenges we have left behind an incredible enterprise grade listening experience that continues to get faster, continues to get higher quality and is secure and reliable 24 hours a day, seven days a week and we'll continue investing heavily to ensure that that only gets better for all of those partners whether they be an external wallet or their infrastructure like an exchange operator. We've had a lot of wins also on the governance side with the Voltaire Catalyst project. We have seen huge wins in participation going from small focus groups to now over 3500 people every single day coming into cardano.ideascale.com competing for 2250000 worth of ADA with fund2. That's just the beginning and every six to eight weeks that's going to increase in scale, in terms of the money and people, the quality... When we ask what is our developer acquisition strategy that's a major part of it because people know that there's money to be made in building on Cardano and that you have the right incentives to go realize your dreams and add value so just as these frameworks like the Marlowe playground and the Plutus playground and other such things like Glow come online and IELE come online the ability to build will be matched by the ability to discuss what to build and fund? What to build through a community driven process that includes greater and greater inclusivity. For example the next fund will include a voting center built right into Daedalus in addition to the cell phone application that we've already launched to vote and we will continue refining that experience relentlessly that's one of our fastest moving teams and I will remind you we are doing this in parallel to the Shelley workstream and the Goguen workstream that we showed you guys today. Finally there's Basho, not the next hard fork combinator event but HFC#3 which we anticipate in Q1 2021.
Sidechains, Hydra
I would like to include a sidechain protocol that allows the movement of value between independent systems through some form of blocking mechanism. We are currently examining and designing a protocol that we think fits very nicely into the way that our system works with mild modifications to the ledger rules. If that and should this be successful then that helps with one of the pillars of Basho interoperability and then the other pillar is scalability. Rob is hard at work working with technical architects and scaling up a team to start de-risking the Hydra protocol and others are hard at work evolving the science behind the Hydra protocol. We have seen great progress on all fronts to de-risk Hydra's roll-out and what's so beautiful about Hydra is it is our belief that the majority if not all of Hydra can be implemented in Plutus. As Plutus rolls out we have a natural constituency to run this infrastructure. The stake pool operators and we have a natural way without an HFC event or special accommodation of rolling out Hydra.
It's not really needed at this level of scaling capacity. We have an enormous throughput already 10 times greater than Ethereum as it is today and room to make it a hundred times greater than what Ethereum is today without Hydra. However as we de-risk this infrastructure solidify the protocols and get out all the kinks. What's so beautiful about it is that we will be able to when the time comes the community can roll out multiple implementations of Hydra so that there is diversity and there will be a natural group of actors to run those channels as we have seen for example with the Bolt spec and the Lightning ecosystem on Bitcoin. The contrasting difference between Lightning and Bitcoin and Hydra and extended UTxO and Cardano is we designed Cardano for Hydra.
Bitcoin was not designed for Lightning and as a consequence it's always more difficult for them to try to make meaningful progress whereas us there's no friction in that relationship. It just fits very nicely through so the roadmap is coming together and Cardano 2020 has definitely started to evolve into quite a mature ecosystem and what's really exciting is we're going from an ecosystem of potential to one of reality and instead of asking what could we do we're showing people what has been done and people are actually doing things every day.
Our commercial team is inundated with requests for coordination and cooperation and deployment. I get numerous emails every single day, well intended to very serious about people wanting to build on the platform and we're really excited about that. We're going to keep this steady systematic relentless march as you saw with the enormity of the news today. It's business as usual and it'll be exactly the same in November only there'll be more and every month. The velocity increases, we burn down the remaining story points to get these things done and things are happening very quickly and we just keep releasing and releasing and releasing and it's a very different time than it was even six months ago.
Community rules
What's so reassuring is we continue to have the best community in all the cryptocurrency space. It's the final point but it's one that I'm most proud of. You see people get to decide where they want to live, what infrastructure they want to deploy, on who they want to work with and when you have a welcoming warm and friendly community that is constructive and productive and their job is to help you get to where you need to go you want to work with those people. When you have a destructive or toxic community that's exclusive hierarchical and not invented here in their mentality people don't want to work with that community. Money can't buy that. I don't care if you have a bank account with four billion dollars or you're a central bank. You can't buy character and you can't buy culture, you have to make it and you have to earn it and if we've accomplished anything over these last five years from the 90 papers now and the million plus lines of code and the incredible releases that have happened and continue to happen we accomplished the greatest thing of all: we built a community to rival that of bitcoin's. I believe with that community we can realize the dream in the coming years of Cardano becoming the financial operating system.
For those who don't have one and giving open prayer and free economic identity to those who need it I am astounded by just how easy it is to roll these things out. They're super hard and complex under the hood but they just feel right and fit right and all the pieces are starting to come together in just the right way and I'm astounded by the fact that when we roll them out community members are there to receive them and take them to the next level.
Thank you all for attending the product update at the end of the month. This was a real good one, just as good as the Shelley one and we are now in the Goguen era with the first HFC event coming in the end of November and we're going to keep pushing them out. Every single one of them will add more capabilities and I encourage everyone to check out the Marlowe playground start building with it. Today things are happening really fast when the mint comes online at the end of November. Start playing around with that, start talking about the multi-token standard. If you're interested in a project our commercial division divisions always' open and you're going to see more and more progress from all entities in this ecosystem and some potentially major announcements before you can think it. Thanks guys it was a good day and thanks to the entire team that made all this happen I'm real proud of all of you.

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!

Round up of Cryptocurrency News #10 Week 28/09 - 4/10

Hello and sorry all its been about a month since serious post. So what has happened this week? 1. Kucoin exchange was hacked for over $150 Million in Bitcoin. Bitfinex and Tether freezes $33 Million of stolen funds. Over this past week we have seen many cryptocurrencies on the exchange be released from the freeze. However, users are still waiting on the main cryptos to be released as KuCoin is working on their security of their platform to make sure it does not happen again. The hacker itself tried to dump his tokens over Binance... Good try lol https://news.bitcoin.com/kucoin-hack-17m-laundered-via-decentralized-exchanges-blockchain-analysis-firm-claims-this-can-still-be-traced/ (HOLY MOLY) https://news.bitcoin.com/kucoin-ceo-says-exchange-hack-suspects-found-204-million-recovered/ 2. Bitcoin outperforms Gold, Nasdaq, 10 year treasury and S&P 500. not surprising at all for us but still very interesting, Bitcoin is up 48% since the start of the year. It appears more people are becoming interested in cryptocurrency as Bitcoin continues to be the best performing asset not just in the past 10 years but of all time. On a more personal note, I was at a small gathering today (within covid restrictions) and I was just saying how i was really interested in cryptocurrency. For the first time ever everyone around me was really interested in what it was and how it worked also talked to a lot of my stock market friends and almost all have pulled out or thinking of pulling out. related: https://dailyhodl.com/2020/10/01/report-details-unprecedented-levels-of-wall-street-interest-in-bitcoin-and-cryptocurrency/ https://dailyhodl.com/2020/10/02/former-goldman-institutional-trader-says-large-investors-now-buying-bitcoin-and-gold-at-same-pace-heres-why/ 3. CBDC news - US federal reserve is actively working on the a digital dollar. From a previous post we know that the European Union is working on a Digital Euro and China is working on their own digital dollar. For me this is a bit of a worrying issue and seems like an upgrade for their own outdated systems completely removing the idea of decentralisation. In addition to this, I find it interesting that in Australia all cryptocurrency tax laws were written in late 2017/2018 and continues to be adapted. In Russia their are harsh penalties for unreported cryptocurrency holdings. In my controversial view I think the technology of blockchain can actually be used to recreate and rewrite a much better future through its innate abilities. we can avoid things like this: https://news.bitcoin.com/jpmorgan-fraud-billion-dollar-settlement/ 4. Highlights on cryptojacking - if you dont know what this is it is when a script or code runs on a computer to mine cryptocurrency using your computer resources. You can block these using other programs or scripts and being safe over the internet. 5. World economic forum names XRP as crypto asset most relevant in central bank digital currency space.

Seems like everyone is bullish on bitcoin and leading crypto projects to make big gains over the next year, sooner rather than later. Bitcoin also holds above $10.5K with over 1Million wallets. Bitcoin interest is gaining throughout the world as many parts are hit by economic crisis.

Bitcoin Continues To Be The Preferred Of The 'crypto Whales' With More Than 400 Thousand Btc Transferred In June

New research carried out with the data shown by Whale-Alert and Bitcoin Block Bot during the month of June 2020, showed that BTC is still the cryptocurrency of choice for crypto whales.
According to the numbers stacked since the alerts issued of high cryptocurrency transactions in the 'crypto verse', Bitcoin remains the king not only in the general market ranking, but also in terms of number of transactions reported by the big known actors like 'Crypto Whales' or Crypto Whales.
The first data shows that Bitcoin was mobilized during the period from June 01 to 30 on 98 occasions, with more than 400,000 BTC transferred between different anonymous addresses and some important exchanges such as Binance, Huobi and Bittrex Exchange.

How to trade Bitcoin Future

How to trade Bitcoin Future


https://preview.redd.it/zel9pxcl8df51.jpg?width=1200&format=pjpg&auto=webp&s=21c74d0ccc5556ea744088a283c44819fba59aef



Bitcoin is troublesome to use.
But bitcoin’s isue may build it additional valuable.
So, what’ reality regarding bitcoin’s future?
Bitcoin mining may be a senseless waste of energy.
As bitcoin hits mainstream media, the subject of bitcoin mining
bubble regarding to pop.For ten years, the media has enjoyed painting bitcoin as a bubble concerning to pop. They’ve gleefully pronounced the bubble popped and bitcoin dead … over 350 times. However the reality regarding bitcoin is that it keeps coming back back. Why?

Charlie Munger called bitcoin “worthless artificial gold.” Others in the media have likened bitcoin to a bubble, a “tulip mania,” and different strong statements
Each time bitcoin improves itself (like with Segwit
Segregated Witnesses. A protocol implemented by Bitcoin to extend transaction speed. SegWit allows a lot of transactions to be written into a single block on a blockchain.

or the Lightning Network), or will increase in value, the media is keen and ready to jump on it, decrying and denouncing it.
Therefore what’s the reality behind bitcoin’s price -- is it extremely a bubble?
The reality regarding bitcoin is straightforward; it's experiencing the same rise and fall cycles as each new technology and asset catego
The web also experienced a bubble. Shares of dotcom firms rose by a thousandpercent on a daily basis. Then it all tumbled down. However we have a tendency to’re still using the web, aren’t we have a tendency to? More than ever, in fact.

Stocks conjointly experienced big boom and bust cycles, especially in their early days.

We might feel like stocks have been around forever -- and to us they need. However stocks conjointly had a starting, and a rough one too. Once upon a time in 1531, when the first stocks were invented, they saw extraordinary volatility, scams, and no regulation. In fact, before stock exchanges, they were sold at occasional shops -- just like cryptocurrencies were sold on la peer to peer

marketplace, before exchanges came online.
Even property, viewed by the majority as “the safest investment” experienced a dramatic cycle. Business Insider reported that “Between 2006 and 2014, nearly ten million homeowners in America saw the foreclosure sale of their own homes.” And tens of thousands became homeless as a result of of it. Nevertheless --- we have a tendency to’re still living in homes, aren’t we?

The future of bitcoin would possibly be the identical as that of stocks, bonds, assets, and the web. It rises and falls like all the others, and it is currently terribly volatile -- but that’s as a result of it’s young.

Stocks have been around for 400 years. Dotcom corporations for forty years. Bitcoin is solely 10 years previous -- and cryptocurrencies, normally, are even younger. But slowly, they will become a part of our daily lives.

Rich investors are manipulating costs!
Look at this headline from the Independent: “Bitcoin price Crash: 'Manipulative Whales

Whale
A very wealthy individual capable of creating massive trades.
View full glossary
' cause Cryptocurrency Market Meltdown!”
It’s sensationalism, pure and straightforward. The article goes on to rant against these therefore-known as “whales” -- individuals who own voluminous dollars of BTC -- as evil-doers who’s solely thought is profit.

This type of sensationalism is meant to harm Bitcoin’s future; to scare people faraway from doing research and thinking for themselves.

Nonetheless, this statement is somewhat true. Up to eighty five% of Bitcoin’s supply is solely owned by onepercent of wallet addresses.




But there’s an important point to be made about these numbers. Most of the prime percentage of wallets is not owned by whales -- but by exchanges

Exchange
On-line platforms on which people can buy and sell cryptocurrencies.

.
However their result is getting smaller and smaller.
A company referred to as Chainalysis -- that makes a speciality of analyzing the Bitcoin blockchain

-- found that “the actual threat that all whales pose to the cryptocurrency economy is relatively low. If they sold off their entire holdings, it'd be effectively a $3.9 billion sale at current costs. That’s not even tenpercent of this total market capitalization of Bitcoin.”
This is as a result of, as I hinted above, several of those wallets holding such vast sums are the ‘cold wallets

’ (wallets held offline) belonging to major exchanges like Coinbase, Kraken, Binance, and more. These wallets cannot be used to manipulate the price, diminishing the potential impact of enormous ‘whales’ selling their positions.
Bitcoin is simply too slow for use as a currency.
The reality regarding Bitcoin is that yes, it's slower than VISA, Mastercard, and alternative centralized electronic payment systems.

Paying together with your credit cards takes seconds and the network can handle payments around the globe twenty fouseven. But, though Bitcoin can additionally be used around the world, confirmation

of payment takes an average of 10 minutes; during the bitcoin craze recently 2017, confirmation times might take hours.
Moreover, VISA on average processes around 2,00zero transactions per second (tps). This means the amount of payments individuals make per second on the network. VISA includes a maximum of twenty four,00zero TPS. Bitcoin, by distinction, has a maximum of ten TPS. This argument has been place forward by several critics over the years and picked up by the media as the doom of bitcoin’s future.

However Bitcoin could be a technology that evolves.
Now let’s assume regarding Bitcoin’s past for a moment. The coin and its underlying technology -- the blockchain -- are only ten years previous. When the web was ten years old -- the year was 1989. Do you keep in mind the net in 1989? I sure do.



payments in exchange for not revealing sensitive info. So, in bound ways that, BTC and cryptocurrencies offer hackers a lot of options.
However money continues to be king for every criminality.
Though it’s true that hackers and phishers do typically ask for payment in BTC

There’s an aphorism: “money talks.” It means that that if you would like to get something done -- the best argument you can build is to place down a stack of money. When Bitcoin rose to fame, the primary headlines focused around Bitcoin being the prime choice for criminality.

But Lilita Infante, Special Agent for the DEA (Drug Enforcement Administration) has some contradictory info regarding this. She was one among a ten-person Cyber Investigative Task Force team whose primary aim was the dark web and crypto-related investigations. This cluster is no little force. They collaborate with the Department of Justice, FBI, and also the Bureau of Alcohol, Tobacco, Firearms and Explosives. And she went on the record to talk regarding what share of bitcoin transactions are literally being employed for illegal things; she said that “illegal activity has shrunk to about 10 p.c.”

Only tenp.c of all the transactions on the Bitcoin network could be used for illegal things. Which number is falling.

The fall in Bitcoin’s use among criminals is due to several factors. The most prominent factor is that Bitcoin is no longer anonymous. Sciencemag wrote a full report on how governments are developing and using techniques to explore the Bitcoin blockchain and notice criminals by tracing their bitcoin payments.

Paying with bitcoin isn’t simple.
I’ve heard this argument flow into widely throughout the years. I still hear it from my grandpa each vacation dinner. He didn’t see a Bitcoin checkout option at the grocery when he bought the turkey -- therefore it’ll never be used.



Perhaps Bitcoin is on its means to being such a store of worth. For 10 years now bitcoin has been ready to be saved and retrieved and exchanged -- and it’s worth has only gone up (bumpy but up).

Bitcoin is difficult to use.
Bitcoin, like all new technologies, isn't the most user-friendly.

You would like to line up a wallet, bear in mind a seed phrase, and several additional steps. Sending and receiving BTC

payments additionally involves steps of copy/pasting long strings of random letters and numbers. It’s powerful, I hear ya.


I additionally keep in mind all the steps I needed to require to send emails back when those were new. Insert a CD from AOL into my computer. Install AOL. Unplug my phone line. Plug in my Modem. Wait for it to make all those noises and finally connect. Then set up my AOL email and password. It was quite the method.

My grandfather never thought emails would come out and even my mother said folks would perpetually like handwriting letters (and using a physical dictionary for spell check!) and sending through the post.


Think about it the approach we tend to assume about gold. Not everyone has gold. It’s also a bit difficult to own.

If you wish to own gold for its ‘store of price’ properties, you wish to seek out a specialized look to buy investment gold. You need to store it somewhere, sort of a personal safe or a bank vault, and bear in mind the password. This is somewhat troublesome.

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!

During the coronavirus, are cryptocurrencies suffering or taking advantage of the moment?

During the coronavirus, are cryptocurrencies suffering or taking advantage of the moment?
Up until just a short time ago cryptocurrencies were considered to be a sort of safe haven. This idea has gained greater strength in the measure in which, during recent periods of crisis and instability, the Bitcoin has risen in value; however, now, with the pandemic of the coronavirus hitting the entire planet, the freefall of the cryptocurrency quotes most used these days shows an uncertain scenario and demystified the option of “safe haven”.
https://preview.redd.it/yspkat1aan151.jpg?width=1280&format=pjpg&auto=webp&s=e692f86d3141a021fce448812f3a3815b886ccb5
Halfway through February, before the before the pandemic became widespread, Bitcoin’s quote reached over 10,200 dollars, its highest quote during the last seven months; but, from that moment on the decline has been resounding – around 40% - so that its present value is in the region of 6,300 dollars. In its fall, Bitcoin dragged other cryptocurrencies along with it, like Ethereum which lost 29% as went from 194 dollars to 137, and Ripple, which ceded 22%.

What provoked the decline in prices?

Cryptocurrencies operate contrary to the traditional financial system, because they don’t need banks; however, this doesn’t make them immune to the economic chaos unleashed by the pandemic.
In China’s case, the country where the virus arose, the analysts waited for the launch of the digital yuan; however, the Wuhan crisis will postpone the presentation of the new cryptoasset between three and six months, since, according to YuanJie Zhang, the director of operations of Conflux, “The majority of the budget’s resources were spent in containing the virus”.
For Zhang, the coronavirus hasn’t had a negative impact on the cryptocurrency mining industry in China, because the majority of these farms continued working and never hired a lot of people.
Nevertheless, the fall in prices was evident. What could have provoked it? This continues to be a subject that divides the experts, since more than a few feel that there are no clear elements that explain the downward trend, because cryptocurrencies aren’t affected by the prices of petroleum and or the global recession.
According to various experts, the decline was expected because Bitcoin, for example, saw its price rise 100% during the last six months and many investors opted to sell them now to cover the losses that they suffered in their portfolios from other assets with variable yield.
Others look for a link to the pandemic and analyze that the collapse in prices was produced at the moment when the bonds and shares fell around the world. The investors suffered so many losses that they had to liquidate assets that, at this time, have enough value to cover their obligations.
“Investors are liquidating alternative assets like gold and cryptocurrencies to comply with obligations of the market and to create cash reserves, a theme that is similar to what happened during the last financial crisis,” stated Matthew Dibb, co-founder and director of Stack operations.
A variation is that the retail investors have sold their cryptoassets so that this way they can obtain money that will allow them to obtain more food, medical supplies and take on other monthly expenses, since extended quarantines impede them from working and, therefore, generate income.

Blockchain initiatives against the coronavirus

The donations in cryptocurrencies to support the most affected areas with medical supplies or to encourage research about the coronavirus have increased in recent times.
The Binance exchange donated 1.4 million dollars to the Chinese authorities for medical supplies. The project was called “Binance for Wuhan”. In addition, Binance Charity continues to be wrapped up in raising five million dollars in cryptocurrencies that make it possible to buy essential medical articles for the countries most affected by the coronavirus.
The crowdfunding platform The Giving Block launched a campaign for donating cryptoassets, in coordination with Gitcoin, an open code reward platform in the Ethereum blockchain.
The decentralized Alliance of AI presented the #COVIDathon, considered the first hackathon designed to help the medical industry to search for solutions that allow them to battle the COVID-19. This alliance depends on more than 50 members of the blockchain.com space, Ocean Protocol, Aragon, Shivom and SingularityNet.
Ripple Labs donated 200,000 dollars to two non-profit organizations, Tipping Point Community and Silicon Valley Community Foundation, to contain the propagation of COVID-19 in the United States.
The Napoli Blockchain Association undertook a crypto fund raiser that made the purchase of a large amount of appliance equipment possible for strengthening medical attention in Italy.

Wanchain Telegram AMA - 05/11/2019 - questions and answers

location: t.me/wanchainchat
most of the questions and answers from AMA that happened on 05/11/2019 on Wanchain Telegram, sorry if I missed any!
  1. question: The current roadmap of Wanchain ends in 55 days. (When) can we expect to see a new one? answer: Yes we have been in many discussions about our roadmap next year. Hopefule we will release that by the end of month. Please feel free to contribute...
  2. question: Will WAN have any burn or buy back in the future, any plan? answer: Wanchain has burned the 21 million WAN (10% reserved for mining rewards) by sending them to an address where the WAN is not recoverable.Here is the address: https://www.wanscan.org/address/0x0000000000000000000000000000000000000000The tx: https://www.wanscan.org/tx/0x6bc3b697e48b95793aae27b8e9aa84f98eebe5beb024b4a051b5845ef547d865PoS rewards are explained here: https://medium.com/wanchain-foundation/wanchain-proof-of-stake-validator-economics-for-upcoming-alpha-testing-d57353a4d0f9
  3. question: What is the team doing more regarding marketing ? How much mcap wan is targeting? Competition is getting too much now.. answer: We are working with a few new marketing partners. Revamping social media, leveraging our ambassador program but giving an extra boost when the DEX with RiveX launches. As well as other dApps we are looking closely at and hoping to have them deployed quite soon.
  4. question: Hello Mr. Lu. It seems integrating new existing blockchains to the wanchain ecosystem is a very slow process... indeed only 2 at the moment (ethereum and bitcoin)... one every 9 months... when is this time going to be reduced and by how much time... ? there are hundreds of blockchains out there... both public and private... I understand the success of wanchain depends on integrating as many blockchains as possible. answer: We are in the process of improving the cross-chain mechanism and make it more open. Once that is done, they will be coming a lot faster. BTW, we are working on EOS integration...
  5. question: Hello. What are your next major plans to boost wanchain ecosystem? Who is going to use wanchain network? Any significant partnerships? answer: We are working with FinNexus and RiveX currently to build the ecosystem. Also we are working with our partner on the cross-chain DEX
  6. question: Does wanchain work for interop with chain like hyperledger and such? answer: Yes we are working with EEA and Hyperledger on the interoperability standards
  7. question: Do feel financially stable? Do you still have funds from ICO to continue as going concern? answer: Yes, we have enough funds to continue our develoment in the coming years
  8. question: My second question is related to the Elevenpaths (Telefonica) / Rivetz / Civic / Wanchain partnership. Is it still alive? Could you please share any details about the progress of that partnership up to date? answer: Hey, I'll take that one. We have a few new things in motion with Telefonica's Eleven Paths. Due to NDA we cannot comment on the specifications but more is definitely coming :)
  9. question: We have seen many stable coins added to Wanchain (DAI, GUSD, TUSD, USDC). But I miss Tether... Are there plans to include USDT in Wanchain? It would be really helpful for WRDEX success IMHO answer: We'd love to integrate with USDT. It will only takes us a few days to integrate with the USDT on Ethereum...A little more challenging for the one on BTC though
  10. question: Next Question : will there be any AMA in binance group for more new users engagement for the WAN ? so many great projects are doing ama in exchange group, team should consider some AMA with current listed exchanges.. answer: That's a great idea and yes we are planning to have more AMAs in/with other communities. After all, we are bridging technically (blockchains) but also their communities. We had a good AMA in the Cryptoverse telegram last week. We also intend to include more team members in future AMAs (business, technical, community, marketing).
  11. question: What's the progress of lanchain, is it wan 4.0 that's due the end of the year? answer: Wanchain recently partnered with PUC Berhad for enterprise blockchain solutions, more info can be found here: https://medium.com/wanchain-foundation/wanchain-partners-with-malaysian-digital-firm-puc-for-enterprise-blockchain-solutions-ddc823474395RiveX is also building on Wanchains private chain to offer enterprise solutions, you can find more info on what RiveX is doing here: https://medium.com/@RiveXOfficial/erox-the-enterprise-super-solution-explained-c5c776c0e6c0
  12. question: i was wondering if its possible to increase the number of validators selected and reduce the amount of reward per selection? Small nodes will get selected more frequently, so people wont just choose large nodes for delegation answer: That is possible by reducing the block time. We have many parameters to play around but all of them require code change. At the stage we want to gather enough data from the POS network before we make any changes...
  13. question: Hi Jack, which month do you expect storemannodes to be implemented? If all goes according to plan. answer: We are doing internal planning right now. Hopefully you can see our roadmap very soon...
  14. question: What work doing our team to increase use cases of wan? answer: We are researching Dapps on different chain and are focusing on cross-chain DEFI applications. That's why we are working with FinNexus and RiveX. Also DEX, Lending applications, Games are coming up...
  15. question: What's your take on mass adoption of wanchain? Do you have any plan or strategy to achieve that?answer: It will be a long process but will be faster than internet mass adoption. We are working with mobile partners like Telefonica and Pundix get us well positioned. Also we are looking into DEXes, DEFI applications, integration with Libra and DCEP and etc.
  16. question: Hi @jackxlu, what will be the boost of WAN in 2020 to build confidence, create awareness and more adoption? Also why work on a cross-chain DEX when you can also work together with a cross-chain DEX, for example Switcheo/Neon Exchange? answer: Each partner has their own technologies and their own priority. We just want to push that forward as soon as we can
  17. question: Hi @jackxlu what is the status of the blockchain interoperability alliance with aion and icon? It’s been a while since there has been any news on that. I know that the focus has been for each project to get their mainnet built and properly functioning. Since all 3 now have working Main nets and projects starting to deploy, will you be working more closely with those other projects again in terms of interoperability? answer: Hey Tim! There is no update here. Projects are focused on their own roadmaps for now and as Jack mentioned above, each project has its own technology so there isn't much need for the interoperability alliance right now. We will, however, bridge all chains together it's just a question of when. We hope to collaborate more with Aion and Icon going forward but we have to continue working on new integrations and eventually come out with a plug and play solution.
  18. question: Is tokenization of building and other real world stuff in wan program? answer: On the enterprise side, we are mostly focused on interoperable reward programs (like with Telefonica's Eleven Paths, PUC Malaysia) as its a blue ocean right now. We are however talking to a few of our partners about creating joint ventures (tech + business) in Asia and Europe. We will leverage each other's technology stacks and business contacts.
  19. question: You only mentioned WAN POS TPS is more than 1000+. Can you showcase the TPS to the community ? Or is there any already we can see it ? answer: Our research team has been working on gathering and analyzing POS data in the past few weeks. We should have the research data published very soon
  20. question: Is it possible to integration with DCEP? I doubt China will allow an altcoin do that, please confirm it. answer: It's too early to tell but we do want to get the right partnership and make that a reality
  21. question: @jackxlu how about SDK for popular programming languages like c# and java? For smart contract development you will only support solidity programming language? I understand the initial choice of this, take advantage of the network effect of developers that already know solidity, but what about all the others? answer: We recently released a SDK for Java. As long there is a demand, we can easily do for any programming language. For smart contract, we are looking into EWASM and hopefully we can support many programming languages for the smart contract
  22. question: Can you share something about the legal status of Wanchain in the US, are there any legal issues/obstacles for getting listed on a US regulated exchange in the future? answer: No legal reasons stopping us from getting listed in the US. We want WAN to be available to anyone that wishes to use our platform. Having said that, there are a number of discussions happening and we are taking necessary precautions to stay ahead, it's just taking very long. That's all we can say about that right now, Adam.
  23. question: @jackxlu can you talk about the recent events in China and their impact on Wanchain? what is wanchain doing to take advantage of china opening up to blockchain? answer: The recent events in China are very exciting. Many people approached me for possible partnership. Our team in China is so busy in different talks in recent days. Wanchain 4.0 release is coming up by the end of year and we have been working with EEA and Hyperledger on the interoperability standards. We have Lanchain as our enterprise solution and Wanchain can integrate with any other types of enterprise blockchain solutions. So we are really well positioned to take advantage of the current blockchain boom in China in the coming years
  24. question: Any concrete plan on embark more developers to wanchain ecosystem? Team alone won't make it in the long run. answer: We plan to build https://wandevs.org/ out further. Wandevs is a community of developers working on technical documentation, cross-chain dApps and tools for Wanchain. We had a soft launch but plan to increase the number of developers and incentives in this program through new guides, challenges and vitual hackathons. We are for example talking to 0xcert now about doing a cross-chain NFT virtual hackathon in the new year.
  25. question: Hi Jack Lu. Amazing to have you here! You perhaps have already answered this question, but will the others blockchain projects ever be able to integrate themselves to Wanchain (plug & play system)? Waiting for wanchain team to do the whole work can be hard. answer: Our plan is to get the solution perfect before our dev community or other projects can integrate with Wanchain by themselves
  26. question: Hi @jackxlu, @machinayz has there been any progress with the potential Belt and Road initiative contract that you spoke of in a previous AMA? Thanks. answer: Sorry Steve, we missed this. There are no further updates here. Li Ni and team are working hard on it though :)
  27. question: Jack Lu, thanks for your work. Wanchain is growing a lot. My question: Are you talking with any retail company for partnership? answer: Not yet but it's a great idea because Wanchain can serve as a gateway for multi-coin payment. Any suggestions?
  28. question: @jackxlu Is there any plan to improve node management ? to pass "partner off-chain" to "partner on-chain"? answer: Not at this point but please send your requirement or suggests to me. Thanks!
  29. question: Do you still believe in Wanchain becoming a top 10 project? Thank you both Oliver and Jack for your time and answers¡ It has been a great AMA. answer: Sure I do believe that. And thanks so much for your support!
Thanks for everyone for participating, sorry if I missed any questions/answers. Stay tuned for any upcoming AMAs!
