Embedable Javascript Bitcoin miner for your website; annoying adverts a thing of the past?

submitted by DOUBLEXTREMEVIL to technology [link] [comments]

Websites had client side javascript Bitcoin miners which gave them to the website as a source of income.

Doesnt have to be bitcoin
Instead of ads, it could be how websites generated money. More people visit, higher income.

Robinhood vs. The Paywall

Paywalls are, technologically speaking, quite fragile. In fact, as of today, if you are quick enough at the keyboard, you can easily copy the full text of a New York Times article before the Javascript kicks in and trims it.
I do this sometimes and I have a fast machine and a fast internet connection, which should make it harder. Other sites are more clever, but for the most part, paywalls are still a bit of a joke.
However, they're getting a lot better and more prevalent. I can imagine that right now an engineer at NYT is working on a better paywall with no practical way of cheating it.
All that aside, an article is just a piece of ordered text and some formatting, and I don't see that changing any time soon. Once you're past the paywall, the text just sits there in your browser, or in your email, or whatever. It can be viewed, copied, pasted, or read by a 3rd party extension.
What would it take, practically speaking, to "Robinhood" that text and make it freely available to everyone whether or not they've paid for it? There are numerous ways to access paywalled content today, which I won't share but aren't hard to find. But I'm interested in whether or not there is a solution that is so robust that it backs publishers into a corner where they need to find another way to make money. And when I say "robust" I mostly mean "legal", because I am assuming that any illegal method would ultimately lose out in a game of legal whack-a-mole (think torrent trackers or darknet markets).
Anyways, some initial considerations...
  1. You'd have to have at least one participant who has access to the paywalled content, but ideally many more than that who can all participate in tossing the content back over the paywall.
  2. You would need to have an immutable and accessible place to put the paywalled content so that other people could point their browsers to that location and see the same content that they would if they were looking at the source.
  3. As noted, you'd want to eliminate as much legal risk as possible. That goes for both the content "suppliers" and the content "consumers" (or, Robinhood and those he gives to).
I am not sure exactly what would happen if I just started copying and pasting paywalled content on, say, Reddit, but I am pretty sure it would catch up with me eventually because I am explicitly re-publishing. This solution would need to be so foolproof that it would put those who would otherwise enforce against it in an untenable position.
So, bear with me, here's what I want to know: how flawed, immoral, antisocial, and generally lacking is the following idea? My suspicion is that it is a pretty bad idea and is also pretty naive, but it's still been fun to think about and maybe some of you would like to discuss it. I am interested in any implications that come to mind.
~
The idea:
If you want to participate in this scheme, you install a browser extension. If you have access to any paywalled content, then every time you visit a page and view that content, the browser extension grabs the text and compresses it to its smallest possible representation.
Next, the browser extension make the smallest possible arbitrary transaction on the blockchain (looks to be about $0.06 currently), and stores as much of the article as it can fit in the OP_RETURN field, which is basically just a blank field for arbitrary text and currently has a size limit of 256 bytes (Note: There are tons of similar ways to accomplish the same thing, any many better blockchains for this use case. I just don't really keep up with the smaller blockchains and think that we can use the Bitcoin blockchain as a simple way to demonstrate the idea).
It may take a few transactions to store an entire article, but once it's part of the blockchain, it's there forever, and anyone who would want to subsequently view that article would only need to have access to the indices of the transactions and software that can de-compress the OP_RETURN values and reconstruct the article. I imagine this would also happen in the browser extension.
In this way, it's a lot like private torrent trackers. Everybody shares what they have access to, and the pieces of data that comprise the underlying media fly around the network freely. The software client is responsible for piecing them together and making the data cohesive for a given end user.
Today, a torrent client is completely legal, but having pirated media on your computer is not. Also, I'm pretty sure that opening your media collection to peers is also illegal, but I'm not actually sure.
Using the blockchain as the storage mechanism changes the calculus a little bit. You're not storing any pirated data on your machine, rather, you are stashing bits and pieces of it in a decentralized ledger, which nobody owns, meaning that nobody is really accountable for it. It's also impossible to take down.
The question of legality here is something like "are you allowed to include copyrighted works in transaction text on the blockchain?". And if not, how many chunks would the article need to be broken apart into to make it no long "The Article", but rather just pieces of arbitrary data which, if put together in the right order, would happen to reproduce "The Article"? Someone who is more knowledgable than I am would need to chime in here.
~
I wanted to get a sense of if this is even practical so I grabbed the text from a NYT article called "Opinion | No, the Democrats Haven’t Gone Over the Edge" by David Brooks.
After running the text through 1000 rounds of compression I got it down to 2702 bytes. The current OP_RETURN size limit for a BTC transaction is 256 bytes, so you would need to make around 10 transactions to store this single article.
And each transaction has a fee that goes to miners, which appears to be around 128 satoshis/byte according to https://privacypros.io/tools/bitcoin-fee-estimato
The BTC sent in a given transaction is recoverable, because it could be sent to a wallet that is owned by the sender, but the fees are unavoidable. Given the current rate, storing a NYT Opinion article on the Bitcoin blockchain, forever, would cost about 2707 * 128 Satoshis, or roughly $37.
So my immediate thought is wow that's expensive. I also know that it's frowned upon by the Bitcoin community and would be perceived as antagonistic by the miners. But my guess is that there's a better way to accomplish the same thing (again, off-chain transactions or using a totally different blockchain such as Ethereum, or BSV).
In fact, in "The unfuckening of OP_RETURN", Shadders shows that one can practically store up to 100kb of text in a given BSV transaction (BSV is a fork of bitcoin, which aims to align more with Satoshi's "original" vision).
The result of Shadders experiment? Well, here's the complete prequel to "Alice and Wonderland" in a single transaction, on the blockchain, forever: https://whatsonchain.com/tx/ef21e71d00b9fce174222e679640b09e29ac8a55f321c93e64b16cc3109959f8
Good thing Alice and Wonderland is in the public domain, right? Or... should it even matter what's "public" and what's "paywalled"?
What do you think?

DV/ABUSIVE COURT There's more to this Nightmare

their father worked for the local internet company decided to spy on me admitted it openly don't have perfect evidence of that at the moment either because I lost the online accounts it was saved on or impossible to connect to any printers. He later quit internet company and work for the electric company then Microsoft . Once he spied on me long enough he felt he had evidence and dirt on me enough to raise my child support to a very unreasonable amount when I already paid 100% for the children and paid a good amount of child support every month and had them 40% of the time . I could not afford to pay it he decided to kidnap my younger one during the times that I would have always have her. My children have been going through the domestic violence an abuse their entire life. the day of the trial hearing, I had denial of service attack. where I could not get Wi-Fi nor data on mobile. that I have always paid for. Which made it so my alarm did not go off and I was late for trail. yes the guardian of alliance said the children would be super with me if I was more stable. which was because online it says I have about 10 more addresses than I actually lived at. She said the kids were not safe with him and his wife. my son 17 yrs, went in courts filed for two restraining orders & provided proof of physical abuse and he was deneyed the judge did not seem to feel as if it was abuse . One day I received a call from my children's father. I was hoping you wanted to discuss the children but all I could hear on the other end Were sounds of computers, similar to a fax machine. Shortly after that I lost all my online accounts had a brute Force attack. My last pass and keeper did not help me either because I couldn't reach them or because they chose not to help. I noticed the last time I was able to access my passwords some of my accounts were changed to my social security number. Which I would never do. So my identity any form of privacy,all my work art an memories gone. my whole digital Life. My son who is in high school lost a lot of his hard work and the Mac, I recently purchased for. I could not access our router majority of the time. while my internet company where he used to work, lied to me and said there's no such thing as a network hack and we're not willing to help. I could not use our cellular data or Wi-Fi on my electronics but majority of the family still could use the internet on some of their mobile devices. I was panicking trying to reach my customers the company that I subcontracted for but unfortunately I was redirected to spammers. I ended up using all of our financial savings to pay rent and buy more mobile devices a new computer and any type of internet security I could possibly fine in a very small town. I could not buy anything else online I had too many online fraud charges that I was continuously fighting. I could not use the vpns I always would get a sever error and my antiviruses somehow were rerouted and I would continuously be locked out. Majority of the new electronics I bought would be compromised and controlled within minutes to a day or two, thanks to the Internet of things. My family can't even reach out for help with their hack devices services with the same local internet company. They are constantly being overcharged slow connection and additional charges like voice over IP . I've purchased at least 10 phones in the last year. My cell phone companies either have no clue or ignored me or treatme as If I was a terrorist, who was just begging to get help controling my data and my children's baby photos. I've gone through over a hundred emails since I kept losing access to them even though I had the password written down. I had DNS poisoning so majority of the websites. I still am I can't even get court forms sometimes server cant find Wacourt.gov & washingtonhelp.org I can't seem to talk to a lawyer that I've been approved for multiple times through the Northwest Justice project. for my mobile phone will consistently hang up. I can't call the non emergency 911. My emails don't go through or are blocked. Many websites I visit seem to be cloned in insecure. JavaScript would not give me access to majority of the security settings in all my browsers. There is always new extensions and apps and open source license for untrustworthy certificate and cant reach the same security settings in my browsers. I cannot turn on or off like family sharing when I don't even have a family connected to that mobile device. Can't turn off USB tethering and Google pay and apple wallets has multiple transactions not by me. cannot turn them off or use them. for they are lightened out or I don't have access. Sim card & ip always changed. 5000 $ in extra international charges hit my credit report along with new numbers emails and new addresses. Cant reach for help when device have so much static and lose connection. If I try to connect my email account to a computer. It will say I need a physical key to access it. as if I set it up myself. when every computer I own now Is broke or has locked me out. I gave up but was sad for I could not keep tabs or communicate with my children. unless I borrowed a phone. They mapped out my family and contacts so if I were to borrow a phone and try to reach out for help I usually reached spam or foreign hotline or got disconnected. Then the locals were acting strange. Like sitting outside our house taking photos of us &things were stolen of property. When we were out of town. then the landlord had strange men over pretending to fix things that didn't need to be fixed installing pipes underground , laying down new soil& having some Wi-Fi farming company working in our yard 5:00 a.m. I also notice a few times the electric companies employees were messing with our power boxes, in the middle of the night . Then My photos came out extremely bright. the family videos look like we lived in a microwave oven. I know it's very strange! I do have evidence. If I would get a new router my children's father would come over take the children and their phones from them and install something on their device saying that he had to change the password on their Netflix account, so he needed to use their phone. When I would purposely break the router the electric company would show up before the internet cable company and be across the street fixing power lines. bought the children new phones and then he puts another restraining order on me and the children saying that I stole my daughters phone and won't allow her to use it. when she didn't want to use it for some reason she has on 5 gb and ends up with no data within a couple days and has to use Wi-Fi all the time. Apple finally told me they couldn't help me with iphone for it was a government issue. I thought that was hilarious for I didn't do anything wrong unless the person who was using my accounts did. I figured it would pass I mean if you're under an investigation. it would only be for a few months right ? Not two years ! well nothing happened I mean there was no reason for anything to happen. I did notice that police were driving by the house a lot. Then I thought maybe it must have been my roommate they might be after. Then why am I the one who lost everything and dealing with network abuse. My roommate was in a bad guy he did have a bit of a criminal history but nothing considered to be violent maybe just a couple drunken stupid events. Then during the process of moving my children and roommates out of the house.while drivin my car mysteriously blew up because of some electrical issue. Luckily the children were not in the car. There were no warnings & no issues with car. It took the fire department about two minutes find me but it was totaled. I could not afford to fix it or have a mechanic look at that time . Then somebody I did not no had it towed and I lost it. I was in the router that I can't get into majority of the time and saw a port forwarding to a local Bitcoin mining pool. Then it I received another server error . He continues to harass me and threaten me or he knows everything we do in our own privacy our own bedrooms where we're going who we're going with how much money says he's recording everything it seems to know everything before I can even share it with a girlfriend. He's throwing everything against me in The family Court and continues to commit perjury while I have proved him wrong multiple times but still aren't getting the protection and respect in this local small town courtroom I have currently moved to Spokane Washington to get away from it I do the traveling for the judge is now took my daughter from coming to Spokane Washington and requiring me to stay with my children at my parents home. When they are almost fully grown she is going to be 15 soon she should have a choice to bpick who she feel safe enough to live with. without him constantly tracking and destroying every electronic I have after calling my daughter then receive Non-Stop spam and scripts over SMS and once I go to my parents more and more viruses are downloaded. I've been told multiple times by a few computer companies and files that I have some sort of invisible beacon. How ? Seattle times has reported that the local electric company and crypto miners are being questioned for unauthorized usage of other families in the small town electricity for maximum power leaving us in a unsafe situation to build more cryptocurrency . Please I appreciate Any help and advice!

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!

Introducing ChipMixerMixing reinvented for your privacy


Clearnet link:
https://chipmixer.com/
What makes ChipMixer special?
ChipMixer creates Bitcoin addresses (chips) and funds them with specific sizes. There are chips with 0.001 BTC, 0.002 BTC, 0.004 BTC and so on till 4.096 BTC. When you deposit your Bitcoins, you receive same amount in chips. For example you deposit 0.112 BTC and you receive 0.064 + 0.032 + 0.016. Each chip was funded before your deposit, so there is no link between them and your deposit on blockchain. They are already anonymous. With each chip, you receive its private key, so you can spend them any time you want.
Why us?
We offer the best privacy you can get from Bitcoin mixer.

  • you have full control over mixing - it makes process random
  • outputs are fungible - every chip is exactly the same
  • outputs are faster than inputs - from blockchain perspective, you spend them before sending to mixer
  • output may be higher than input - optional betting inside
  • you can use multiple small inputs to merge into one big output off-chain
  • outputs can be used instantly - private key is yours and you set miner's fee
  • no fee, donation only - pay as much as you want
  • no accounts, no bitcodes to link your inputs
  • optional signed source of funds
  • we wait 48h for your input transaction and we can wait more on request
  • lightweight pages, no javascript required
How to use it with example
Step 1 - deposit
You receive input address. You deposit 0.1 BTC on received address and wait for one confirmation.
Step 2 - mixing
Your 0.1 BTC is exchanged for chips: 0.064 + 0.032 + 0.004.
You click on split button for 0.064 chip exchanging it for two 0.032 chips.
You click on split button for 0.004 chip exchanging it for two 0.002 chips. You click donate on smallest chip. Thank you!
Now you have 3 * 0.032 + 0.002. You click withdraw all.
Step 3 - withdraw
You see list of four private keys. Each marked with its size (3 * 0.032 BTC and 0.002 BTC) and public key. There is no on-chain connection between them and funds you deposited.
You import them into your wallet Electrum wallet and they are ready to be spent.
Total mixing time: 1 blockchain confirmation
Total cost: 0.002 BTC donate. You pay what you want.
