4 Ways to Use Bitcoin - wikiHow

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!

The Unofficial Cardano FAQ - V3

(if you would like to add information or see mistakes, just comment below and I will credit you)
What is Cardano? Cardano is an open source and permissionless "Third Generation" blockchain project being developed by IOHK. Development and research started in 2015, with the 1.0 mainnet launching in 2017. Cardano blockchain is currently being developed into two layers. The first one is the ledger of account values, and the second one is the reason why values are transferred from one account to the other.
  1. Cardano Settlement Layer (CSL) - The CSL acts as the ledger of account or balance ledger. This is an idea created as an improvement of bitcoin blockchain. It uses a proof-of-stake consensus algorithm known as Ouroboros to generate new blocks and confirm transactions.
  2. Cardano Computation Layer (CCL) - The CCL contains the data how values are transferred. Since the computation layer is not connected to balance ledger, users of the CCL can create customized rules (smart contracts) when evaluating transactions. (https://support.bitkub.com/hc/en-us/articles/360006678892-What-are-the-two-layers-of-Cardano-)
IOHK has the contract with an undisclosed party to develop the project until the end of 2020, at which point the community may elect another development team - on the assumption that the voting infrastructure has been completed. However CEO Charles Hoskinson has stated that they will develop the project until it is completed, and they are simply financed until the end of 2020.
Cardano was the first project built on a peer-reviewed scientific development method, resulting in dozens of research papers produced by IOHK. Among these papers is Ouroboros Genesis, proving that a Proof of Stake protocol can be just as secure as Proof of Work - which was originally developed for Bitcoin, and refined for Ethereum. This PoS protocol considerably lowers the resources cost to maintain network while still maintaining security and network speed.
Cardano as a financial infrastructure is not yet completed, With significant development to be rolled out.
What were the other two generations of blockchain? Gen 1 was Bitcoin. It exists by itself and talks to nobody but Bitcoin. It is capable of peer to peer transactions without a third party in such a way that you cannot cheat the system. This was a major step forward for the E-cash concept that people have been working on for the 20 years prior.
Gen 2 was Ethereum and other smart-contract platforms that allow other coins and platforms to be built on top of their infrastructure. These coins can interact with others on the platform, but cannot interact with other platforms. Meaning it is still not truly interoperable. Most Gen 2 blockchains are also using Proof of Work likes Bitcoin, which effects scaling. Also missing is a built-in method to pay for upgrades and voting mechanics for decision making.
Gen 3 blockchains are a complete package designed to replace the current financial infrastructure of the world. Cardano is using Proof of Stake to ensure security and decentralisation(Shelley). Scaling through parallel computation (Hydra in Basho), Sidechains to allow the platform to interact with other platforms (Basho), and also include mechanisms for voting for project funding, changes to the protocol and improvement proposals (Voltaire). Finally smart contracts platform for new and established projects that are developer friendly (Goguen).
Who is the team behind Cardano? There are three organisations that are contributing to the development of Cardano. The first is the Cardano Foundation, an objective, non-profit organisation based in Switzerland. Its core responsibilities are to nurture, grow and educate Cardano users and commercial communities, to engage with authorities on regulatory and commercial matters and to act as a blockchain and cryptocurrency standards body. The second entity is IOHK, a leading cryptocurrency research and development company, which holds the contract to develop the platform until 2020. The final business partner is Emurgo, which invests in start-ups and assists commercial ventures to build on the Cardano blockchain.

What is the difference between Proof of Work and Proof of stake? Both these protocols are known as “consensus protocols” that confirm whether a transaction is valid or invalid without a middleman like Visa or your bank. Every node (active and updated copy of the blockchain) can agree that the transaction did take place legitimately. If more than half validators agree, then the ledger is updated and the transaction is now secured. Proof-of-Work (PoW) happens when a miner is elected to solve an exceptionally difficult math problem and gets credit for adding a verified block to the blockchain. Finding a solution is an arduous guessing game that takes a considerable amount of computing power to compete for the correct answer. It is like “pick a number between 1 and one trillion” and when you get it right, you get $30,000 in Bitcoin, so the more computers you have working on it, the faster you can solve it. Also the more people who are trying to solve the same block, the harder the algorithm, so it may become 1 in 20 trillion. The downside is the massive amounts of power required to run the computers that run the network, and the slow pace that blocks are solved. To “Hack” a PoW system, you need 51% of the computing power, which would allow you to deny transactions, or spend the same coin twice. At the moment there are 8 main mining operations for bitcoin, and 4 of them make up more that 51% of the mining power.
PoS instead selects a coin at random that already exists, and the person who owns that coin is elected to put the work in to validate the block. This means there is no contest and no guessing game. Some computer power is required, but only a fraction of a PoW system. The complex nature of selecting a coin that exists on the correct and longest chain and is owned by someone who can complete the block, AND in such a way that it is secure AND that computer currently running AND that person also having an incentive to complete the work, has made the development of PoS very slow. However only a few years ago it wasn’t even possible. In this method, the more of the coin (ADA) you stake, the more likely you are to be selected to close a block. Cardano also allows you to delegate your stake to someone else to validate the block so they do the work, and you share in the reward for doing so.
To “hack” a PoS blockchain you need to own 51% of the tokens, which is significantly harder than owning 51% of the computing power.
What is ADA and how is it different to Cardano? Cardano is the name of the network infrastructure, and can be thought of like a rail network. ADA is the native token that has been developed alongside Cardano to facilitate the network operation. This helps confusion and maintains distinction, compared to Ethereum being the native token of Ethereum. Similar to bitcoin or any other token, ADA can be sent peer to peer as payment, but is also the reward for running the network, and what is taken as transaction fees.
In this metaphor “Cardano” is the train tracks, that everything runs on. A stake pool would be the locomotive, facilitating transactions on the network while ADA is the coal that powers the locomotive. The train carriages are Decentralised applications (Dapps) that are also running on cardano tracks, but are not actively powering the network.
What is staking Cardano is a Proof of Stake protocol, and uses already existing coins like a marker to ensure security. The protocol chooses a coin at random and the owner of that coin is elected to validate a block of transactions. Staking is the process of adding your ADA coins to a Pool that has the resources to run the network. If the pool you have chosen to "delegate" your stake to is chosen to close/validate a block, then you get a portion of the rewards. The ADA never leaves your wallet, and you can "undelegate" whenever you like. this increases stability of the network and also gives an incentive to pool operators to invest the time and hardware required to run a pool.
What is a stake-pool and how does it work? Cardano.org FAQ on the issue goes into much more detail
A stake pool is where the computing power of the network takes place. During ITN there was 1200 registered stake pools while 300 were creating blocks. You can manage your own stake-pool or delegate your ADA to an already registered pool. Rewards are determined by the protocol, however the pool may elect to charge fee Percentages, or flat rate fee to upkeep their pool.
Can I Stake my ADA right now? The staking testnet has closed, If you participated in the Incentivised Test Net and earned rewards, instructions to check the balance are here.
However if you have just purchased some or it was held on an exchange, then you will need to wait until the Shelley mainnet launch happening at the end of July 2020.
Where do I stake my ADA? Daedalus Flight wallet, and Yoroi Wallet (as a chrome extension) are the current best options. Adalite and several other third-party wallets also exist. Coinbase will also allow staking as a custodial service, and many exchanges may offer “staking as a service” so you can leave your coins on the exchange and still earn rewards if you enjoy trading. I do not recommend leaving coins on an exchange unless you are actively trading.
What are the staking rewards now and what can I expect on a return in the future? The Incentivised Test Net (ITN) Delivered 10%-15%pa returns on average. The future of staking will most likely be lower, but will depend on the amount of ADA staked across the network and the amount of network traffic.
Check https://staking.cardano.org/en/calculato for a clearer picture.
what is a Pledge? To stop one person operating many pools, the rewards that a pool earns will vary depending on the amount of personal ADA they “pledge” to open the pool. This means that 50 pools with a 1,00ADA pledge each will be overall less profitable than 1-2 pool with the max ADA pledge (unknown but likely around 300k). Even if the 50 pools have the same over stake delegated by other users and have a better chance of being selected to close a block, the 50 pools may receive lower rewards.. (at least that is the theory)
Who is IOHK? IOHK is a for-profit software engineering company founded by CEO Charles Hoskinson and Jeremy Wood in 2015 that has taken a scientific approach to the development of blockchain. IOHK started with “first principles” and looked at questions like “what is a blockchain” and “what should a blockchain be able to do” rather than accepting the established paradigm of Bitcoin and Ethereum. IOHK was originally Input Output Hong Kong, but is now Input Output Global and is based in Wyoming USA employing over 230 staff. IOHK has established research labs in several universities in order to complete the Cardano project, and is also developing Ethereum Classic, Atala, Mantis and possibly other Blockchain related programs and infrastructure.
Who is Charles? Charles Hoskinson is an early adopter of cryptocurrencies, American entrepreneur and cryptocurrency specialist. Charles Co-founded Ethereum with Vitalik Buterin and 5-8 others, However he only worked on that project for approximately six-months. Charles is now the CEO of IOHK and the director of The Bitcoin Education Project.
Why isn’t ADA on coinbase? Cardano and coinbase have recently connected in a big way. With IOHK turning over all their ADA to the custodial services of Coinbase. This means that Cardano and Coinbase have been working together for some time and there is a strong partnership forming. Staking and cold storage will be available and trading on Coinbase will most likely become available after the release of Shelley (although no official word yet)
Why Doesn’t Cardano have a Wikipedia Page? Wikipedia has strict guidelines on what can be turned into an article. As there has been no coverage of Cardano from mainstream media or “noteworthy” sources, there is no article yet. Wikipedia will also not accept sources from IOHK as they are not considered “reliable” and must come from a third party. This will most likely change soon.
Cardano does have a dedicated community driven wiki
https://cardanowiki.info/wiki/Home
What is Atala and why do I care?*
Atala is a suite of services being developed on top of the cardano blockchain by IOHK that focusses on credential certification, for things like education, work history and degrees (Atala Prism). Product counterfeiting protection through registering products on a blockchain and create taper-proof provenance. This does not only apply to Gucci handbags, but also medication, art, and anything that can be counterfeited (Atala Scan). As well as supply chain tracking to see issues and inefficiencies with greater transparency(Atala Trace).
Im new, how much is a good investment?
Cardano is still a speculative market and although there is amazing potential here, it is still only potential. When investing in any High risk market like Crypto, only every invest what you are willing to lose. Cardano may be testing the 10c barrier now. But in March it dumped to 1.7c. And if you suddenly need your money back during the dump then you are out of luck. Do your research before you FOMO in. Start with a small amount and send it between wallets and exchanges to understand how the system works. Store your private keys offline (or online cloud service but encrypted) with a method that is unlikely to be damaged AND have multiple copies. So in the case of a house fire or a blow to the head, or the cloud service being shutdown/destroyed, you do not lose your money.

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!

Blockchain in Healthcare – Webcast Q&A

Blockchain in Healthcare – Webcast Q&A
On our website, you can find the original article: https://block.co/webcastqa-blockchain-in-healthcare/
Block.co third webcast ” Blockchain in Healthcare: Bridging Trust in response to COVID-19“ received amazing feedback! We gathered some of the best experts in the field, Georgina Kyriakoudes, Ahmed Abdulla, Dimitri Neocleous, Dr. Alice Loveys to share their experience in the industry and discuss with us the latest updates in the sphere of Healthcare! In its third series of webcasts, Block.co gathered 253 people watching the event from 59 different countries, for a 90-minute webcast where guests answered participants’ questions.
Below is a list of the questions that were made and were not answered due to time constraints during the Blockchain in Healthcare webcast. Please note that the below information is only for educational purposes!
Question 1: I like what Dimitrios was saying regarding ownership and transfer. Health and social care have invested much in Information Management systems and processes. Transfer between NHS and social care is a typical block. Can you elaborate on how the blockchain sits across that – leapfrogs yet goes with the grain of what is already there in terms of shared records protocols, the exponentially growing types of professionals, pharmacists, careers, etc. that need early access to these records for better decision making.
Block.co Team Answer: Blockchain technology has the potential to improve healthcare, placing the patient at the center of the health care ecosystem, while providing security, privacy, and interoperability of health data. Blockchain could provide a new model for health information exchanges and transform electronic medical records to be more efficient, disintermediated, and secure. While it is not a cure, this new, Blockchain in Healthcare rapidly evolving field provides a sandbox for experimentation, investment, and proof-of-concept testing.
Healthcare systems around the world are preparing road maps that define critical policy and technical components needed for nationwide interoperability, including:
  • Ubiquitous, secure network infrastructure
  • Verifiable identity and authentication of all participants
  • Consistent illustration of authorization to access electronic health data, and several other requirements.
However, current technologies don’t totally address these necessities, and as a result, they face limitations associated with security, privacy, and full ecosystem interoperability.
Blockchain technology creates distinctive opportunities to scale back complexity, improve trustless collaboration, and create secure and immutable data. National Healthcare Systems need to track this rapidly evolving field to identify trends and sense the areas where government support may be needed for the technology to realize its full potential in health care. To form blockchain’s future, they ought to take into account mapping and gathering the blockchain ecosystem, establishing a blockchain framework to coordinate early-adopters, and supporting a pool for dialogue and discovery.

Question 2: What about the “compatibility” of blockchain solutions in healthcare with GDPR and/or other regulations about personal data protection.
Block.co Team Answer: The General Data Protection Regulation (GDPR), Europe’s new framework for data protection laws, has a vital impact on healthcare organizations. During this more and more patient-centric world where global healthcare organizations collect a large set of data on patients to produce improved health outcomes, this increased regulation has an even larger impact.
GDPR presents challenges across all industries and includes language that has a special impact on healthcare. The regulation defines “personal” data as “any information relating to an identified or identifiable natural person (data subject); an identifiable natural person is one who can be identified, directly or indirectly, in particular by reference to an identifier such as a name, an identification number, location data, an online identifier or to one or more factors specific to the physical, physiological, genetic, mental, economic, cultural or social identity of that natural person.” On top of this definition, GDPR contains three extra, important definitions that pertain to health data:
  1. “Data concerning health” is defined by the GDPR as “personal data related to the physical or mental health of a natural person, including the provision of health care services, which reveal information about his or her health status.”
  2. “Genetic data” is outlined by the GDPR as “personal data relating to inherited or acquired genetic characteristics of a natural person which give unique information about the physiology or the health of that natural person and which result, in particular, from an analysis of a biological sample from the natural person in question.”
  3. “Biometric data” is “personal data resulting from specific technical processing relating to the physical, physiological, or behavioral characteristics of a natural person, which allows or confirms the unique identification of that natural person, such as facial images or dactyloscopic data.”
As described in Article 6 of GDPR, processing of personal data is considered lawful if: (1) the data subject has given consent; (2) it is necessary for the performance of a contract to which the data subject is a party; (3) it is necessary for compliance with a legal obligation; (4) it is necessary to protect the vital interest of the data subject or another natural person; (5) it is necessary for the performance of a task carried out in the public interest; (6) it is necessary for the purposes of the legitimate interests pursued by the controller or third party.
However, healthcare organizations that usually manage health data, have an added responsibility to take care of “data concerning health,” “genetic data,” and “biometric data” to a higher standard of protection than personal data, in general. GDPR prohibits the processing of these forms of health data unless one of the three conditions below would apply as per Article 9.
a. The data subject must have given “explicit consent.”
b. “Processing is necessary for the purposes of preventive or occupational medicine, for the assessment of the working capacity of the employee, medical diagnosis, the provision of health or social care or treatment or the management of health or social care systems and services …”
c. “Processing is necessary for reasons of public interest in the area of public health, such as protecting against serious cross-border threats to health or ensuring high standards of quality and safety of health care and of medicinal products or medical devices …”
Consent VS Explicit Consent – If one pays attention, there’s a difference in the GDPR’s health data use conditions (calls for “explicit consent”) and the general definition (calls for “consent”). Thus, there’s an ongoing debate as to what constitutes the difference between “unambiguous” and “explicit” consent. Despite the debate and the final legal clarifications, there is no doubt that in the purposes of the healthcare the “explicit consent” must have the strongest agreement form listing in detail the use(s) of data and covering the cases of data transfers and storage.
Question 3: How can we use blockchain technology by the government in Africanflavored government, say by Ministry of health to have patient autonomy of medical records that can be accessed by any government hospital irrespective of the ailment and record printed by the previous hospital and doctor, such as referral cases without having to open a new file in the referred hospital.
Block.co Team Answer: Perhaps that would be an ideal implementation of the Block.co solution issuing a digital certificate of medical examination on an Open Public Blockchain such as the Bitcoin blockchain, that would be decentralized in nature, easy to validate online without any special wallets, and would be provided by the patient on-demand, to refer to treatments received in other hospitals or areas. But this would require that the practitioner is aware and can use the open-source code or use Block.co services to issue these certificates. Alternatively, there could be the use of a wallet to store these medical credentials to be submitted on demand to health practitioners. Moreover, there would need to be an alignment of regulation in the matter as decentralized repositories are not recognized at the moment.

Question 4: Is there any data breach threat in the blockchain using a poorly protected private key at communication?
Block.co Team Answer: Millions of health care records have already been breached, and in attempts to combat this issue, solutions often result in the inaccessibility of health records. Health providers often send information to other providers, and this often ends up in mishandling of data, losing records, or passing on inaccurate and old data. In some cases, only one copy of an updated health record exists, and this may result in the loss of information. Health records often contain personal information such as names, social security numbers, and home addresses. When it comes to Blockchain in Healthcare, a poorly protected private key is always a factor to consider. A private key allows us to sign a transaction and spend funds residing in an address (public key) by providing ownership with the signature. It is a unique string of information that represents proof of identification inside the blockchain, which includes the right to access and control the participant’s wallet. It must be kept secret, as it is effectively a personal password. In the case that that private key is poorly protected, there is always a data breach threat.
Question 5: The medical record of a patient is owned by the patient. What happens if a doctor accesses the record without the consent of the patient? Using the smart contract, could there be a governing body, say a legal system that can call the doctor to order?
Block.co Team Answer: Rather than having each physical and electronic copies of records, blockchains may enable the shift to electronic health records (EHR). When looking at Blockchain in Healthcare, medical records on the blockchain would be within the management of the patient rather than a third party, through the patients’ private and public keys. Patients may then control access to their health records, making transferring information less cumbersome. Because blockchain ledgers are immutable, health information may not be deleted or tampered with. Blockchain transactions would be accompanied by a timestamp, permitting those with access to maintain updated information. The doctor would not be able to access the record without the consent of the patient. A patient would need to sign the transaction in a smart contract in order to transfer patient details to the doctor.
Question 6: So, how are private data protected when the patient is simply notified that unauthorized access just took place on her medical record? and, how are the negative results of this breach rectified towards the patient?
Block.co Team Answer: The patient would be notified to sign a transaction enabling access to the party requesting access to the specific medical record. In other cases, there could be a multi-signature wallet requiring multiple transactions in the cases where the patient may need assistance, for example, when underage or when not in a healthy state of mind, or being non-responsive or in critical condition. The patient needs to be responsible for his own data and be empowered through awareness and know-how of this technology. With great power, comes also great responsibility, although it is yet a challenge to enable computer illiterate people to interact with this technology.
Question 7: Can the same record of a patient still be shared with private hospitals and say another government/private hospital abroad on the same blockchain?
Block.co Team Answer: Depending on whether the information is on a public blockchain or a private blockchain. When on a private blockchain, they will need to be granted permission to access the blockchain accordingly.
Question 8: No one has directly spoken about ownership where a large research institution/ consortium is working with the data – it is not solely the person who has said so…
Block.co Team Answer: Indeed, it is solely not the person who has a say so. Technology may be used in both evil and good ways and it is still the obligation and responsibility of people within governments to ensure human liberties and rights are preserved when utilizing such powerful technologies such as blockchain and sometimes the combination of blockchain with AI, IoT, and biometrics. Blockchain in Healthcare, in the same way, that it can empower individuals and increase their standard of living and prosperity, at the same time, it can also empower corrupt governments with alternative agendas and totalitarian states. Block.co believes it is most important for people to be educated around the matter and be able to form a voice and movement to safeguard their human liberties and rights, hence our continuous effort on discussing these matters with our community and providing education, powered by the pioneers in the space, the University of Nicosia.

The Blackmail Email Scam (part 4)

THIS THREAD IS NOW ARCHIVED, THE LATEST THREAD CAN BE FOUND HERE: https://old.reddit.com/Scams/comments/g8jqnthe_blackmail_email_scam_part_5/

TEXT, PHONE CALL, AND PHYSICAL MAIL VARIANTS ARE COVERED IN THE LATEST THREAD.

IF YOU RECEIVE A BLACKMAIL EMAIL, PLEASE REDACT THE PERSONAL INFORMATION AND POST IT AS A COMMENT ON THIS THREAD SO THAT OTHERS WHO RECEIVE THE SAME EMAIL CAN FIND IT THROUGH GOOGLE.

FIRST THREAD: https://www.reddit.com/Scams/comments/8gsjba/the_blackmail_email_scam/

SECOND THREAD: https://www.reddit.com/Scams/comments/9srjen/the_blackmail_email_scam_part_2/###

THIRD THREAD: https://old.reddit.com/Scams/comments/biv65o/the_blackmail_email_scam_part_3/

There have been many recent posts about the blackmail email scam, so I have written this post and will keep it stickied until the posts about the scam die down. If you are reading this because you have received one of these emails and you are worried, you can stop worrying. The blackmail email scam is a spam campaign that is sent out to thousands of addresses at a time. In al cases, the threats are lies and you do not have anything to worry about. In many cases, the emails will contain information about you such as your name, part or all of your phone number, and your password. The emails may also look like they were sent from your own email address. The data is gathered from data breaches, and if the email looks like it came from your account that is due to email spoofing. You can use the service Have I Been Pwned? to see if you are in any publicly known data breaches. If you receive an email that contains a password that you currently use, you should immediately change that. Current recommended password guidelines say that you should use a different, complex password for every account. You can generate and save passwords using a password manager for convenience. You should also be using two factor authentication using an app like Google Authenticator instead of receiving codes through SMS.
Here are some news articles about this scam. Here is a story from Brian Krebs, and here is a story from the New York Times.
Below are a few examples, but if you receive an email that is similar but not the same as the examples you see, that does not matter and does not mean that the email is real. The spammers constantly switch up their templates in order to bypass spam filters, so it's normal to receive an email that hasn't yet been posted online.
Hey there
So I am the hacker who cracked your email address and device a few weeks back.
You typed in your pwd on one of the sites you visited, and I intercepted that.
Here is your password from (redacted) upon time of compromise: (redacted)
Obviously you can can change it, or even already changed it.
However it won't really matter, my malware modified it every time.
Do not really try to contact me personally or find me.
Via your email, I uploaded harmful code to your Operation System.
I saved your entire contacts together with buddies, fellow workers, loved ones along with a entire history of visits to the World wide web resources.
Also I set up a Virus on your system.
You aren't my only target, I generally lock computers and ask for a ransom.
But I was hit by the web pages of romantic material that you normally stop by.
I am in shock of your own fantasies! I have never ever noticed anything at all like this!
Consequently, when you had enjoyment on piquant web-sites (you know what I am talking about!) I made screenshot with utilizing my program from your camera of yours device.
There after, I put together them to the content of the currently viewed site.
There will certainly be giggling when I send these pics to your connections!
Nevertheless I am certain you do not need this.
Therefore, I expect to have payment from you for my silence.
I feel $859 is an satisfactory price for this!
Pay with Bitcoin.
My Bitcoin wallet is xxxxxxxxxxxxxxxxxxxxxxxxxxxxx
If you do not really understand how to do this - submit in to Google 'how to transfer money to the bitcoin wallet'. It is easy.
Immediately after getting the given amount, all your files will be right away destroyed automatically. My computer virus will also get rid of itself through your operating-system.
My Trojan viruses have auto alert, so I know when this specific e mail is read.
I give you 2 days (48 hours) to make a payment.
If this does not occur - just about all your associates will get outrageous pictures from your darkish secret life and your system will be blocked as well after two days.
Do not end up being foolish!
Police or buddies won't support you for sure ...
P.S I can provide you with recommendation for the future. Do not type in your security passwords on risky web pages.
I wish for your wisdom.
Bon voyage.
Your computer device was attacked by the malicious app . Whats the trouble? I placed my malicious agent on a erotica portal, you clicked on this data and promptly adjusted the malware to your computer . The hostile program made your selfie-camera shooting and I enjoy the videotape with you dash your doodle. In next 5 hours this hostile program copied all your contacts. Right now, I receive your all your contact information and video with you masturbating, and now if you wish me to destroy all the data affect payment 350 $USD in BTC digital currency. Other way I want forward that this record to all your contacts . I forward you my Bitcoin wallet - XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX You possess 27 hours after reading. In a case if I possess transaction I am going to undo that this record once for all. I beg pardon for my mistakes- I live in China . P.S. this postal address, I have thieved it
Good day,
If you had been more careful while caressing yourself, I wouldn't worry you. I don't think that playing with yourself is very bad, but when all your colleagues, relatives and friends get a video recording of it - it is definitely bad for you.
I placed malicious software on a website for adults (with porn) which was visited by you. When the target taps on a play button, your device starts recording the screen and all cameras on your device begin to work.
Moreover, my program allows a remote desktop connection with keylogger function from the device, so I could collect all contacts from your e-mail, messengers and other social networks. I'm writing on this e-mail cuz it's your working address, so you must check it.
I suppose that three hundred twenty usd is good enough for this little misstep. I made a split screen video (recorded from your screen (u have interesting tastes ) and camera ooooooh... its awful AF)
So it's your choice. If you want me to erase this compromising evidence, use my Bitcoin wallet address: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX You have one day after opening my message; I put a special tracking pixel in it, so when you will open it I will see. If you want me to show you the proofs, reply to this message and I will send my creation to five contacts that I got from your contacts.
P.S. You can try to complain to the police, but I don't think that they can help, the investigation will last for 5 month- I'm from Ukraine - so I dgf lmao

This excellent post as Subway & Dairy Queen.
Hello!
I'm a programmer who cracked your email account and device about half year ago. You entered a password on one of the insecure site you visited, and I catched it.
Of course you can will change your password, or already made it. But it doesn't matter, my rat software update it every time.
Please don't try to contact me or find me, it is impossible, since I sent you an email from your email account.
Through your e-mail, I uploaded malicious code to your Operation System. I saved all of your contacts with friends, colleagues, relatives and a complete history of visits to the Internet resources. Also I installed a rat software on your device and long tome spying for you.
You are not my only victim, I usually lock devices and ask for a ransom. But I was struck by the sites of intimate content that you very often visit.
I am in shock of your reach fantasies! Wow! I've never seen anything like this! I did not even know that SUCH content could be so exciting!
So, when you had fun on intime sites (you know what I mean!) I made screenshot with using my program from your camera of yours device. After that, I jointed them to the content of the currently viewed site.
Will be funny when I send these photos to your contacts! And if your relatives see it? BUT I'm sure you don't want it. I definitely would not want to ...
I will not do this if you pay me a little amount. I think $877 is a nice price for it!
I accept only Bitcoins. My BTC wallet: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
If you have difficulty with this - Ask Google "how to make a payment on a bitcoin wallet". It's easy. After receiving the above amount, all your data will be immediately removed automatically. My virus will also will be destroy itself from your operating system.
My Trojan have auto alert, after this email is looked, I will be know it!
You have 2 days (48 hours) for make a payment. If this does not happen - all your contacts will get crazy shots with your dirty life! And so that you do not obstruct me, your device will be locked (also after 48 hours)
Do not take this frivolously! This is the last warning! Various security services or antiviruses won't help you for sure (I have already collected all your data).
Here are the recommendations of a professional: Antiviruses do not help against modern malicious code. Just do not enter your passwords on unsafe sites!
I hope you will be prudent. Bye.
Same as before but they increased the amount
I got an order from someone to kill you and your family
but I am far from your house
if you still love your family, I ask you to transfer 0.1 BTC to me.

Time started after open this mail. To track the reading of a message and the actions in it, I use the facebook pixel. Read that in this link
Hello!
I am a hacker who has access to your operating system.
I also have full access to your account.
I've been watching you for a few months now.
The fact is that you were infected with malware through an adult site that you visited.
If you are not familiar with this, I will explain.
Trojan Virus gives me full access and control over a computer or other device.
This means that I can see everything on your screen, turn on the camera and microphone, but you do not know about it.
I also have access to all your contacts and all your correspondence.
Why your antivirus did not detect malware?
Answer: My malware uses the driver, I update its signatures every 4 hours so that your antivirus is silent.
I made a video showing how you satisfy yourself in the left half of the screen, and in the right half you see the video that you watched.
With one click of the mouse, I can send this video to all your emails and contacts on social networks.
I can also post access to all your e-mail correspondence and messengers that you use.
If you want to prevent this,
transfer the amount of $500 to my bitcoin address (if you do not know how to do this, write to Google: "Buy Bitcoin").
My bitcoin address (BTC Wallet) is: x
After receiving the payment, I will delete the video and you will never hear me again.
I give you 50 hours (more than 2 days) to pay.
I have a notice reading this letter, and the timer will work when you see this letter.
Filing a complaint somewhere does not make sense because this email cannot be tracked like my bitcoin address.
I do not make any mistakes.
If I find that you have shared this message with someone else, the video will be immediately distributed.
Best regards.
Hey, I know your password is:
Your computer was infected with my malware, RAT (Remote Administration Tool), your browser wasn't updated / patched, in such case it's enough to just visit some website where my iframe is placed to get automatically infected, if you want to find out more - Google: "Drive-by exploit".
My malware gave me full access and control over your computer, meaning, I got access to all your accounts (see password above) and I can see everything on your screen, turn on your camera or microphone and you won't even notice about it.
I collected all your private data and I was spying on you, I RECORDED (through your webcam) embarrassing moments of you, you know what I mean!
After that I removed my malware to not leave any traces.
I can publish all your private data everywhere and I can send the videos to all your contacts, post it on social network, publish it on the whole web, including the darknet, where the sick people are!
Only you can prevent me from doing this and only I can help you out in this situation.
Transfer exactly 1200$ with the current bitcoin (BTC) price to my bitcoin address.
It's a very good offer, compared to all that horrible shit that will happen if I publish everything!
You can easily buy bitcoin here: www.paxful.com , www.coingate.com , www.coinbase.com , or check for bitcoin ATM near you, or Google for other exchanger. You can send the bitcoin directly to my address, or create your own wallet first here: www.login.blockchain.com/en/#/signup/ , then receive and send to mine.
My bitcoin address is:
Copy and paste my address, it's (cAsE-sEnSEtiVE)
I give you 3 days time to transfer the bitcoin!
As I got access to this email account, I will know if this email has already been read. If you get this email multiple times, it's to make sure you read it and after payment you can ignore it. After receiving the payment, I will remove everything and you can life your live in peace like before.
Next time update your browser before browsing the web!
