Technical: The Path to Taproot Activation
Taproot! Everybody wants to have it, somebody wants to make it, nobody knows how to get it! (If you are asking why everybody wants it, see: Technical: Taproot: Why Activate?) (Pedants: I mostly elide over lockin times) Briefly, Taproot is that neat new thing that gets us:
Multisignatures (n-of-n, k-of-n) that are just 1 signature (1-of-1) in length!! (MuSig/Schnorr)
Better privacy!! If all contract participants can agree, just use a multisignature. If there is a dispute, show the contract publicly and have the Bitcoin network resolve it (Taproot/MAST).
Activation lets devs work get back to work on the even newer stuff like!!!
Cross-input signature aggregation!! (transaction with multiple inputs can have a single signature for all inputs) --- needs Schnorr, but some more work needed to ensure that the interactions with SCRIPT are okay.
Block validation - Schnorr signatures for all taproot spends in a block can be validated in a single operation instead of for each transaction!! Speed up validation and maybe we can actually afford to increase block sizes (maybe)!!
SIGHASH_ANYPREVOUT - you know, for Decker-Russell-Osuntokun ("eltoo") magic!!!
OP_CHECKTEMPLATEVERIFY - vaulty vaults without requiring storing signatures, just transaction details!!
So yes, let's activate taproot!
The SegWit Wars
The biggest problem with activating Taproot is PTSD from the previous softfork, SegWit. Pieter Wuille, one of the authors of the current Taproot proposal, has consistently held the position that he will not discuss activation, and will accept whatever activation process is imposed on Taproot. Other developers have expressed similar opinions. So what happened with SegWit activation that was so traumatic? SegWit used the BIP9 activation method. Let's dive into BIP9!
bit - A field in the block header, the nVersion, has a number of bits. By setting a particular bit, the miner making the block indicates that it has upgraded its software to support a particular soft fork. The bit parameter for a BIP9 activation is which bit in this nVersion is used to indicate that the miner has upgraded software for a particular soft fork.
timeout - a time limit, expressed as an end date. If this timeout is reached without sufficient number of miners signaling that they upgraded, then the activation fails and Bitcoin Core goes back to the drawing board.
Now there are other parameters (name, starttime) but they are not anywhere near as important as the above two. A number that is not a parameter, is 95%. Basically, activation of a BIP9 softfork is considered as actually succeeding if at least 95% of blocks in the last 2 weeks had the specified bit in the nVersion set. If less than 95% had this bit set before the timeout, then the upgrade fails and never goes into the network. This is not a parameter: it is a constant defined by BIP9, and developers using BIP9 activation cannot change this. So, first some simple questions and their answers:
Why not just set a day when everyone starts imposing the new rules of the softfork?
This was done classically (in the days when Satoshi was still among us). But this might argued to put too much power to developers, since there would be no way to reject an upgrade without possible bad consequences. For example, developers might package an upgrade that the users do not want, together with vital security bugfixes. Either you live without vital security bugfixes and hire some other developers to fix it for you (which can be difficult, presumably the best developers are already the ones working on the codebase) or you get the vital security bugfixes and implicitly support the upgrade you might not want.
Sure, you could fork the code yourself (the ultimate threat in the FOSS world) and hire another set of developers who aren't assholes to do the dreary maintenance work of fixing security bugs, but Bitcoin needs strong bug-for-bug compatibility so everyone should really congregate around a single codebase.
Basically: even the devs do not want this power, because they fear being coerced into putting "upgrades" that are detrimental to users. Satoshi got a pass because nobody knew who he was and how to coerce him.
Suppose the threshold were lower, like 51%. If so, after activation, somebody can disrupt the Bitcoin network by creating a transaction that is valid under the pre-softfork rules, but are invalid under the post-softfork rules. Upgraded nodes would reject it, but 49% of miners would accept it and include it in a block (which makes the block invalid) And then the same 49% would accept the invalid block and build on top of that, possibly creating a short chain of doomed invalid blocks that confirm an invalid spend. This can confuse SPV wallets, who might see multiple confirmations of a transaction and accept the funds, but later find that in fact it is invalid under the now-activated softfork rules.
Thus, a very high threshold was imposed. 95% is considered safe. 50% is definitely not safe. Due to variance in the mining process, 80% could also be potentially unsafe (i.e. 80% of blocks signaling might have a good chance of coming from only 60% of miners), so a threshold of 95% was considered "safe enough for Bitcoin work".
Why have a timeout that disables the upgrade?
Before BIP9, what was used was either flag day or BIP34. BIP34 had no flag day of activation or a bit, instead, it was just a 95% threshold to signal an nVersion value greater than a specific value. Actually, it was two thresholds: at 75%, blocks with the new nVersion would have the new softfork rules imposed, but at 95% blocks with the old nVersion would be rejected (and only the new blocks, with the new softfork rules, were accepted). For one, between 75% and 95%, there was a situation where the softfork was only "partially imposed", only blocks signaling the new rules would actually have those rules, but blocks with the old rules were still valid. This was fine for BIP34, which only added rules for miners with negligible use for non-miners.
The reasons miners signalled support was because they felt they were being pressured to signal support. So they signalled support, with plans to actually upgrade later, but because of the widespread signalling, the new BIP66 version locked in before upgrade plans were finished. Thus, the timeout that disables the upgrade was added in BIP9 to allow miners an escape hatch.
The Great Battles of the SegWit Wars
SegWit not only fixed transaction malleability, it also created a practical softforkable blocksize increase that also rebalanced weights so that the cost of spending a UTXO is about the same as the cost of creating UTXOs (and spending UTXOs is "better" since it limits the size of the UTXO set that every fullnode has to maintain). So SegWit was written, the activation was decided to be BIP9, and then.... miner signalling stalled at below 75%. Thus were the Great SegWit Wars started.
BIP9 Feature Hostage
If you are a miner with at least 5% global hashpower, you can hold a BIP9-activated softfork hostage. You might even secretly want the softfork to actually push through. But you might want to extract concession from the users and the developers. Like removing the halvening. Or raising or even removing the block size caps (which helps larger miners more than smaller miners, making it easier to become a bigger fish that eats all the smaller fishes). Or whatever. With BIP9, you can hold the softfork hostage. You just hold out and refuse to signal. You tell everyone you will signal, if and only if certain concessions are given to you. This ability by miners to hold a feature hostage was enabled because of the miner-exit allowed by the timeout on BIP9. Prior to that, miners were considered little more than expendable security guards, paid for the risk they take to secure the network, but not special in the grand scheme of Bitcoin.
ASICBoost was a novel way of optimizing SHA256 mining, by taking advantage of the structure of the 80-byte header that is hashed in order to perform proof-of-work. The details of ASICBoost are out-of-scope here but you can read about it elsewhere Here is a short summary of the two types of ASICBoost, relevant to the activation discussion.
Overt ASICBoost - Manipulates the unused bits in nVersion to reduce power consumption in mining.
Covert ASICBoost - Manipulates the order of transactions in the block to reduce power consumption in mining.
Now, "overt" means "obvious", while "covert" means hidden. Overt ASICBoost is obvious because nVersion bits that are not currently in use for BIP9 activations are usually 0 by default, so setting those bits to 1 makes it obvious that you are doing something weird (namely, Overt ASICBoost). Covert ASICBoost is non-obvious because the order of transactions in a block are up to the miner anyway, so the miner rearranging the transactions in order to get lower power consumption is not going to be detected. Unfortunately, while Overt ASICBoost was compatible with SegWit, Covert ASICBoost was not. This is because, pre-SegWit, only the block header Merkle tree committed to the transaction ordering. However, with SegWit, another Merkle tree exists, which commits to transaction ordering as well. Covert ASICBoost would require more computation to manipulate two Merkle trees, obviating the power benefits of Covert ASICBoost anyway. Now, miners want to use ASICBoost (indeed, about 60->70% of current miners probably use the Overt ASICBoost nowadays; if you have a Bitcoin fullnode running you will see the logs with lots of "60 of last 100 blocks had unexpected versions" which is exactly what you would see with the nVersion manipulation that Overt ASICBoost does). But remember: ASICBoost was, at around the time, a novel improvement. Not all miners had ASICBoost hardware. Those who did, did not want it known that they had ASICBoost hardware, and wanted to do Covert ASICBoost! But Covert ASICBoost is incompatible with SegWit, because SegWit actually has two Merkle trees of transaction data, and Covert ASICBoost works by fudging around with transaction ordering in a block, and recomputing two Merkle Trees is more expensive than recomputing just one (and loses the ASICBoost advantage). Of course, those miners that wanted Covert ASICBoost did not want to openly admit that they had ASICBoost hardware, they wanted to keep their advantage secret because miners are strongly competitive in a very tight market. And doing ASICBoost Covertly was just the ticket, but they could not work post-SegWit. Fortunately, due to the BIP9 activation process, they could hold SegWit hostage while covertly taking advantage of Covert ASICBoost!
UASF: BIP148 and BIP8
When the incompatibility between Covert ASICBoost and SegWit was realized, still, activation of SegWit stalled, and miners were still not openly claiming that ASICBoost was related to non-activation of SegWit. Eventually, a new proposal was created: BIP148. With this rule, 3 months before the end of the SegWit timeout, nodes would reject blocks that did not signal SegWit. Thus, 3 months before SegWit timeout, BIP148 would force activation of SegWit. This proposal was not accepted by Bitcoin Core, due to the shortening of the timeout (it effectively times out 3 months before the initial SegWit timeout). Instead, a fork of Bitcoin Core was created which added the patch to comply with BIP148. This was claimed as a User Activated Soft Fork, UASF, since users could freely download the alternate fork rather than sticking with the developers of Bitcoin Core. Now, BIP148 effectively is just a BIP9 activation, except at its (earlier) timeout, the new rules would be activated anyway (instead of the BIP9-mandated behavior that the upgrade is cancelled at the end of the timeout). BIP148 was actually inspired by the BIP8 proposal (the link here is a historical version; BIP8 has been updated recently, precisely in preparation for Taproot activation). BIP8 is basically BIP9, but at the end of timeout, the softfork is activated anyway rather than cancelled. This removed the ability of miners to hold the softfork hostage. At best, they can delay the activation, but not stop it entirely by holding out as in BIP9. Of course, this implies risk that not all miners have upgraded before activation, leading to possible losses for SPV users, as well as again re-pressuring miners to signal activation, possibly without the miners actually upgrading their software to properly impose the new softfork rules.
BIP91, SegWit2X, and The Aftermath
BIP148 inspired countermeasures, possibly from the Covert ASiCBoost miners, possibly from concerned users who wanted to offer concessions to miners. To this day, the common name for BIP148 - UASF - remains an emotionally-charged rallying cry for parts of the Bitcoin community. One of these was SegWit2X. This was brokered in a deal between some Bitcoin personalities at a conference in New York, and thus part of the so-called "New York Agreement" or NYA, another emotionally-charged acronym. The text of the NYA was basically:
Set up a new activation threshold at 80% signalled at bit 4 (vs bit 1 for SegWit).
When this 80% signalling was reached, miners would require that bit 1 for SegWit be signalled to achive the 95% activation needed for SegWit.
If the bit 4 signalling reached 80%, increase the block weight limit from the SegWit 4000000 to the SegWit2X 8000000, 6 months after bit 1 activation.
The first item above was coded in BIP91. Unfortunately, if you read the BIP91, independently of NYA, you might come to the conclusion that BIP91 was only about lowering the threshold to 80%. In particular, BIP91 never mentions anything about the second point above, it never mentions that bit 4 80% threshold would also signal for a later hardfork increase in weight limit. Because of this, even though there are claims that NYA (SegWit2X) reached 80% dominance, a close reading of BIP91 shows that the 80% dominance was only for SegWit activation, without necessarily a later 2x capacity hardfork (SegWit2X). This ambiguity of bit 4 (NYA says it includes a 2x capacity hardfork, BIP91 says it does not) has continued to be a thorn in blocksize debates later. Economically speaking, Bitcoin futures between SegWit and SegWit2X showed strong economic dominance in favor of SegWit (SegWit2X futures were traded at a fraction in value of SegWit futures: I personally made a tidy but small amount of money betting against SegWit2X in the futures market), so suggesting that NYA achieved 80% dominance even in mining is laughable, but the NYA text that ties bit 4 to SegWit2X still exists. Historically, BIP91 triggered which caused SegWit to activate before the BIP148 shorter timeout. BIP148 proponents continue to hold this day that it was the BIP148 shorter timeout and no-compromises-activate-on-August-1 that made miners flock to BIP91 as a face-saving tactic that actually removed the second clause of NYA. NYA supporters keep pointing to the bit 4 text in the NYA and the historical activation of BIP91 as a failed promise by Bitcoin developers.
We have discussed BIP8: roughly, it has bit and timeout, if 95% of miners signal bit it activates, at the end of timeout it activates. (EDIT: BIP8 has had recent updates: at the end of timeout it can now activate or fail. For the most part, in the below text "BIP8", means BIP8-and-activate-at-timeout, and "BIP9" means BIP8-and-fail-at-timeout) So let's take a look at Modern Softfork Activation!
Modern Softfork Activation
This is a more complex activation method, composed of BIP9 and BIP8 as supcomponents.
First have a 12-month BIP9 (fail at timeout).
If the above fails to activate, have a 6-month discussion period during which users and developers and miners discuss whether to continue to step 3.
Have a 24-month BIP8 (activate at timeout).
The total above is 42 months, if you are counting: 3.5 years worst-case activation. The logic here is that if there are no problems, BIP9 will work just fine anyway. And if there are problems, the 6-month period should weed it out. Finally, miners cannot hold the feature hostage since the 24-month BIP8 period will exist anyway.
PSA: Being Resilient to Upgrades
Software is very birttle. Anyone who has been using software for a long time has experienced something like this:
You hear a new version of your favorite software has a nice new feature.
Excited, you install the new version.
You find that the new version has subtle incompatibilities with your current workflow.
You are sad and downgrade to the older version.
You find out that the new version has changed your files in incompatible ways that the old version cannot work with anymore.
You tearfully reinstall the newer version and figure out how to get your lost productivity now that you have to adapt to a new workflow
If you are a technically-competent user, you might codify your workflow into a bunch of programs. And then you upgrade one of the external pieces of software you are using, and find that it has a subtle incompatibility with your current workflow which is based on a bunch of simple programs you wrote yourself. And if those simple programs are used as the basis of some important production system, you hve just screwed up because you upgraded software on an important production system. And well, one of the issues with new softfork activation is that if not enough people (users and miners) upgrade to the newest Bitcoin software, the security of the new softfork rules are at risk. Upgrading software of any kind is always a risk, and the more software you build on top of the software-being-upgraded, the greater you risk your tower of software collapsing while you change its foundations. So if you have some complex Bitcoin-manipulating system with Bitcoin somewhere at the foundations, consider running two Bitcoin nodes:
One is a "stable-version" Bitcoin node. Once it has synced, set it up to connect=x.x.x.x to the second node below (so that your ISP bandwidth is only spent on the second node). Use this node to run all your software: it's a stable version that you don't change for long periods of time. Enable txiindex, disable pruning, whatever your software needs.
The other is an "always-up-to-date" Bitcoin Node. Keep its stoarge down with pruning (initially sync it off the "stable-version" node). You can't use blocksonly if your "stable-version" node needs to send transactions, but otherwise this "always-up-to-date" Bitcoin node can be kept as a low-resource node, so you can run both nodes in the same machine.
When a new Bitcoin version comes up, you just upgrade the "always-up-to-date" Bitcoin node. This protects you if a future softfork activates, you will only receive valid Bitcoin blocks and transactions. Since this node has nothing running on top of it, it is just a special peer of the "stable-version" node, any software incompatibilities with your system software do not exist. Your "stable-version" Bitcoin node remains the same version until you are ready to actually upgrade this node and are prepared to rewrite most of the software you have running on top of it due to version compatibility problems. When upgrading the "always-up-to-date", you can bring it down safely and then start it later. Your "stable-version" wil keep running, disconnected from the network, but otherwise still available for whatever queries. You do need some system to stop the "always-up-to-date" node if for any reason the "stable-version" goes down (otherwisee if the "always-up-to-date" advances its pruning window past what your "stable-version" has, the "stable-version" cannot sync afterwards), but if you are technically competent enough that you need to do this, you are technically competent enough to write such a trivial monitor program (EDIT: gmax notes you can adjust the pruning window by RPC commands to help with this as well). This recommendation is from gmaxwell on IRC, by the way.
Decentr ($DEC) - foundational cross-chain and cross-platform DeFi protocol
Decentr is a protocol designed to make blockchain/DLT mainstream by allowing DeFi applications built on various blockchains to “talk to each other”. Decentr is a 100% secure and decentralised Web 3.0 protocol where users can apply PDV (personal data value) to increase APR on $DEC that users loan out as part of of our DeFi dLoan features, as well as it being applied at PoS when paying for stuff online. Decentr is also building a BAT competitor browser and Chrome/Firefox extension that acts as a gateway to 100% decentralised Web 3.0
Allows DeFi Dapps to access all Decentr’s dFintech features, including dLoan, dPay. Key innovation is that the protocols is based on a user’s ability to leverage the value of their data as exchangeable “currency”.
Decentr is building foundational chain-agnostic protocols that will support “true” 100% DeFi Dapps, a 100% secure and decentralised, user-centric alt economy. DeFi dApps inter-connected by Decentr can talk to each other and share PDV (personal data value) of their users. PDV is best described as a personalized “exchange rate” (in a sense social reputation where more effort leads to more rewards and NOT more capital to more rewards. ) between currencies that users apply at point-of-sale to make the cost of goods and services cheaper online. PDV is applied to the APR users earn on $DEC (native token) that they hold that they loan out as part of the investing pool. PDV will also allow uncollateralized loans on their dLoan platform, and also on platforms like Aave and Compound.
Decentr will implement ZKsync to get super cheap and super fast transactions across the ETH network. It is also working with HoloChain and Tomochain to allow connect their DeFi ecosystem to the Ethereum DeFi ecosystem. Decentr has DEEP TIES and a PARTNERSHIP with Holochain: https://medium.com/@DecentrNet/decentr-holochain-ama-29d662caed03
Decentr is also building a browser and Chrome/Firefox extension - a gateway that “transitions” Web 2.0 into a 100% decentralised Web 3.0 via their suite of decentralised dFintech and dCommunications features. The browser adds a 100% decentralised “user layer” to current blockchain protocols so that applications built on blockchain can actually “talk to each other”. The browser uses encryption all the time and the power of blockchain to keep private keys safe. Browser will offer a more robust and innovative type of blockchain storage and caching that is much faster than VPN or TOR. It will allow surfing .onion addresses as well as the regular ones. >>BAT browser 400m marketcap, DEC marketcap 4m<<
Decentr is researching a hardware application, powered by Decentr software, that would greatly enhance current IoT networks. It’s called a “Smart Chip Node” (SCN) and will adhere to 4G LTE standards (with in-built 5G capability), which means connectivity between devices will match or exceed current speed and connectivity, dramatically improving stability and coverage of standalone devices, such as a laptop or tablet, as well as IoT devices, such as home routers and modems.
Decentr uses Coinbase API to optimise integrated implementation of the user layer and Blockchain as a Service (BaaS) to allow users to leverage cloud-based solutions to build, host and use their own blockchain apps. Tierion’s technological infrastructure, the Chainpoint Proof protocol, will come into play whenever a user adds something in Tierion’s data store. Hyperledger Fabric and R3 Corda private blockchains are used as an immutable transaction database for data transfers, including the following tech: R3 Corda, Hyperledger Fabric, Ansible, Bitbucket Pipelines, AWS, Node.JS, GoLang, Kotlin and CouchDB.
Implements a system of layered security protocols based on a radically-new software architecture that combines Elliptic Curve Cryptography (ECC)4 and Sobol sequencing with a n-dimensional chain as part of AI-enhanced, platform-wide community consensus mechanism — a mechanism that assigns mutually agreed value to data and user security protocol upgrades (further encouraging enhanced data integrity) by deploying a Delegated Proof of Stake (DPoS) protocol.
Bank of England has reached out to Decenr to discuss the potential of a UK CBDC upon hearing about the potential of their tech. Decentr is consistent with their own R&D into a "dGBP" and they requested a top-level document for review >> Decentr created this proposal: https://decentr.net/files/Decentr_Consultancy_Doc_UK_CBDC.pdf
A fee is charged for every transaction using dPay whereby an exchange takes place between money (fiat and digital) and data, and vice versa, either as part of DeFi features or via a dApp built on Decentr. They are launching pilot programmes in the following industries:
Banking/PSP Industry: On Product launch, due to Decentr’s powerful PSP connections (including the worlds #2 PSP by volume), a medium-scale pilot program will be launched, which will seed the network with 150,000 PSP customers in primarily the Spanish/LAC markets, generating revenue from day one.
“Bricks and Mortar” Supermarket/Grocery Industry: Decentr aims to ensure the long-term competitiveness of “bricks and mortar” supermarkets against online-only grocery retailers, such as Amazon, by a) building secure tech that allows supermarkets to digitise every aspect of their supply chains and operational functions, while b) allowing supermarkets to leverage this incredibly valuable data as a liquid asset class. Expected revenue by Year 5: $114Mn per year.
Online Advertising Industry: Decentr’s 100% decentralised platform credits users secure data with payable value, in the form of PDV, for engaging with ads. The Brave browser was launched in 2012 and in 8 years has reached over 12 million monthly active users, accented by as many as 4.3 million daily active users.
TOKEN $DEC AND SALE
Decentr recently complete their token sale on a purchase portal powered by Dolomite where they raised $974,000 in 10 minutes for a total sale hardcap of 1.25M. The $DEC token is actively trading on multiple exchanges including Uniswap and IDEX. Listed for free on IDEX, Hotbit, Hoo, Coinw, Tidex, BKex. Listed on CoinGecko and Coinmarketcap.

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:
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.
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.
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.
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 Bitcoin Conspiracy (an enthusiast's perspective)
I keep coming across comments, especially in this sub, from people claiming that Bitcoin was created by the CIA or some government agency as part of the plan for the NWO and cashless society. I want to share my experience and try to clear up the confusion surrounding this topic. I first got involved with Bitcoin in late 2016 when I heard about it and got some while at a libertarian festival. Back then it was still very popular among the agorist community and was being promoted as THE silver bullet that was going to disrupt the global fiat banking system. Putting preconceptions aside, a new user might ask, "what's so special about Bitcoin? We already have digital currencies." Well, you only need to read the first page of the whitepaper to discover what the original intent of Bitcoin was. It most definitely was not intended to be a tool for central banks to subjugate the world to a centralized global currency. Quite the opposite in fact. Read the full whitepaper here. When I first learned about Bitcoin, it forced me to learn about economics, then the Federal Reserve, then one by one the dominoes fell and down the conspiracy rabbit hole I went. In 2017 (actually it started a few years earlier, but I wasn't paying attention back then) there was a very heated debate in the Bitcoin community regarding scaling. I'll try to break it down simply: In the very early days, when Bitcoin was just a project being worked on by a few very technical people, no one knew about it. All it took was a handful of people running the software on their laptops to mine new coins. Since there was not much computing power on the network, it meant there could easily be a spam attack where a malicious user could join the network and generate many gigabytes of spam transactions that would overload and crash the network. To prevent this, Satoshi implemented a limit of 1MB per block, to protect the network until there was enough computing power to be able to handle larger blocks. This measure worked, and Bitcoin grew exponentially. Satoshi vanished in 2010, after WikiLeaks attracted unwanted attention to the project by accepting Bitcoin donations. He left clear instructions for his successors that the 1MB block size limit was meant to be increased once the network could support high levels of user traffic. At the time, there still was not much use, so it wasn't until around 2014 that blocks started hitting the 1MB cap and all of a sudden users had to compete (by paying higher transaction fees) in order to get their transaction mined into the next block. Up until then, sending a Bitcoin transaction would cost $0.0001 (hundredth of a penny) or less, no matter if you were sending $0.10 or $1,000,000. Now, since block space was limited, fees started to rise, as miners would only include the transactions with the highest fees. Over the next couple years, transaction fees went up dramatically, at times reaching as high as $100 to send a single transaction. The solution was obvious - raise the block size limit. But this led to a heated debate, and this is where the conspiracy became obvious to those who were paying attention. Since Bitcoin was decentralized and open source, anyone could contribute, but certain people controlled the commit access to the github repo, and it became apparent that those individuals had been compromised, as any and all mention of increasing the block size was met with fierce resistance. There was a misinformation campaign to discredit anyone arguing for larger blocks. The argument was that larger blocks would mean users could not run the software on their low-power personal devices and laptops; that by increasing the block size it would lead to mining centralization. Well, if you read the whitepaper linked above, you'll see that Satoshi predicted this. He knew mining would eventually be left to "specialized server farms" while normal users could use what he termed Simplified Payment Verification (SPV) wallets. But this point was consistently shot down in the community, and especially on /bitcoin. There was a MASSIVE censorship campaign in the bitcoin subreddit that continues to this day where anyone who questions the official narrative or even asks a basic technical question is immediately banned. /bitcoin today is nothing but a cesspit of price memes and misinformation. Go to /btc for the uncensored discussions (but beware of trolls). In 2017 the debate was finally settled, sort of. Now known as "Bitcoin Core" (the name of the official Bitcoin software), the developers implemented a change known as SegWit (Segregated Witness) which fundamentally altered the way the software validates transactions. It was implemented as a "soft fork" rather than a "hard fork". I'll explain the difference. In a fork, the network comes to a consensus on new rules that all participants must follow. In a hard fork, the changes are non-backwards compatible, so all users must update their software or else be left behind on a dead network. Hard forks happen all the time in software development, but in the case of SegWit, the developers refused to make any non-backwards compatible changes for fear it might alienate users. Again, another unfounded fear. "We can't ever upgrade the technical capabilities of the network (such as the block size) because some people might not go along with it." All kinds of mental gymnastics were performed to justify their refusal to increase the block size, and there was nothing anyone could do about it except fork as an independent project. The 1MB block limit is now essentially set in stone for BTC. So in August 2017, Bitcoin Cash (BCH) hard forked by increasing the block size limit to 8MB, along with some other changes. Fast forward to December 2017 and Bitcoin was at its all time high of nearly $20,000. But fees were also astronomical and because of the 1MB block size limit, a huge backlog formed, and some people had to wait days or even weeks for their transaction to confirm. If anyone was trying to cash out into fiat and didn't want to pay a $100 transaction fee, by the time their transaction got confirmed the price had already crashed. This event was largely responsible for the bear market of 2018. Everything that happened was predicted by those who knew what was going on. A company called Blockstream had essentially wrestled control of Bitcoin from the original developers and shut them out or gained control over them, and started working on turning Bitcoin into a settlement layer for their product called Lightning Network. LN is a complicated topic that I don't want to get into, but essentially it's a framework that recreates all the same problems inherent in the banking system that Bitcoin was meant to solve. Blockstream's goal is to profit from creating, and then "solving" those problems by charging users fees for all kinds of custodial services. In my personal opinion, it's obvious that the original Bitcoin project has been hijacked and repurposed into a tool for the central banks. The propaganda is being pushed in some conspiracy circles that Bitcoin was created BY the central banks in order to discourage people from researching the true history. What is now commonly called "Bitcoin" is not the original project, but a Trojan horse. The project that most closely follows the original design is Bitcoin Cash, and that is where almost all organic development is happening, and personally I feel that it's picking up steam lately as more people wake up to what's happening in the economy right now. Unfortunately most people are still unaware of how fundamentally broken BTC is now and so as new users run toward cryptocurrency to escape the dollar collapse, most will fall straight into the trap and be stuck with BTC that they won't be able to use without paying exorbitant fees and/or submitting to the very same tracking system they are trying to get away from. This is a very deep rabbit hole but I think I've written enough for now. I hope this info helps people make sense of what's going on with Bitcoin. I know it's confusing enough even without so much deception taking place so hopefully this helps. Read the Bitcoin FAQ over on /btc.
From Conspiracy to Fact: An analysis of the COVID-19 Pandemic, Information Control, and the New World Order (Appendix includes hundreds of citations) - PART 1
UPDATE: This article is now available as a printable PDF with embedded hyperlinks for navigation through sources. This link will be valid thru July 9: https://ufile.io/4mpkg4x6
PLEASE NOTE: This article may be updated periodically with new information and links as they become available. All referenced information and a whole lot more is indexed and linked in the relatedappendix posts.Please feel free to crosspost, share, and take from my ideas to build your own. Namaste. Part 1 | Part 2 | Appendix A | Appendix B Hello. My name is Chris. I am nobody, really. An average citizen. I am an overweight 42 year old white male from the Midwestern suburbs of the US who has been fortunate enough to live a pretty comfortable life. I used to be a freelance graphic designer with a focus on small businesses, but I'm coming to terms with the fact that that career and part of my life is more than likely over in light of current events. Oh well, it was fun while it lasted. I've always been concerned about social injustice and tried to stay politically informed, even dabbling in some activism here and there. At times I've stepped away from paying attention for my own mental health, or due to laziness, defeatism, whatever. But I've never stopped caring, or trying, to fight the good fight and do the right thing. The news recently has of course swept us all up, and touched all our lives in some way or another. The world has never seen anything like the "Coronavirus Pandemic," and it's clear that our society will be changed forever when we finally come out the other end of this mess. But I've had the luxury of time recently, and in reading the news about things that were going on, I couldn't help but notice the patterns, and that a lot of stuff didn't exactly make sense. So, here we go, with the "conspiracy theory." I hate that term, because although it's technically accurate, it's been demonized and weaponized by the media and society at large to take on a bad connotation. Tinfoil hats, alien abductions, crazy people muttering to themselves, etc. You've no doubt got a lot of images in your mind of a conspiracy theorist. And make no mistake, what I'm going to tell you here is all currently very popular conspiracy theory. However, I think that by removing opinions and conjecture from it, and focusing on facts and things that have already happened, I can present this huge amount of overwhelming, disparate information in a way that makes it less a "theory" and more a "research project." And so that is how I have approached this. I have spent the last week doing little else besides reading every news and opinion article I could find, saving and organizing hundreds of links, and assembling a coherent, logical outline to organize and present these theories, and more importantly, facts. There are a lot of less-than-reputable sites and publications out there, and I have tried when at all possible to provide sources from verifiable news sites, with a wide range of slants and focuses, to illustrate that what is happening is not part of any one particular political agenda. I hope that you take the time to check the links, really look into the information presented here, and form your own opinions. Please do not just take my word for it. To that end, there are also a few links mixed in that are labeled as having come from conspiracy. These are well-written and well-reasoned posts from other concerned citizens that I think are worth reading, and relevant to the discussion here. One last thing - If you are new to most of these ideas, the information presented here is more than likely going to seem overwhelming at first. I encourage you now, and always, to take mental health breaks for yourself, and put down your phone or turn off your computer. The information will be here when you come back. And as you'll soon understand, what is happening is an unstoppable tide, truly a force of nature at this point, and there is nothing you can do to fight it, so try your hardest to relax, put on some chill music, hug your dog, and most of all... BREATHE. - - - - - - - - - - - - - - - - - - - - - If you start researching conspiracy theory, you're going to find a lot of information. Some much better or worse presented than others, and some much more plausible or unbelievable than others. Despite the seeming ridiculousness of some things you might read, I encourage you to always approach new information with an open mind. That said though, I have one main principle that guides all my beliefs about conspiracy theories, and that is the "Filter of Likelihood." Essentially, you have to ask yourself how possible, how likely, and how feasible a piece of information is. Furthermore, you need to ask yourself what the motivation would be. In many cases, it's quite easy to see how something makes a lot of sense based on other known info, whereas some theories seem rather implausible no matter how you look at it. I am interested only in the plausible, and where possible, the already actualized. Additionally, there's a lot to be said, and a lot that has already been written on many of these topics, so I will focus on current events and simple concepts. I will also ask you to open your mind to possibility. Please consider this as you evaluate new information:
Do you believe there are things going on in the world that you don't know about yet?
Do you believe that there is technology and science you've never heard of?
Do you believe that society is progressing at an increasing rate?
Do you believe that as populations grow, we require new societal strategies?
Do you believe that those with power and money want to retain their power and money?
Of course you believe all these things, and none of these are wild or unusual concepts. Rather, these are very basic concepts that apply to everyone, and always have. They are all part of our shared human experience, and undeniable facts of life. Populations grow, societies evolve, technology advances, and the world changes. And most important to our discussion here, people, families, and empires constantly jockey for power and control, while fighting for resources, power, fame, and... MONEY. We all hate TicketMaster, right? Who do they think they are, what the hell is this bullshit "service fee," etc. It's something everyone can get behind. But did you know that TicketMaster willingly cultivates that image? That venues, teams, and artists, in their pursuit of more money, raise fees and then let TicketMaster be the bad guy and take the heat so their reputations remain intact? There are many more people, organizations, and other entities in the world playing that same role for those who really have the money, who really call the shots. And those who call the shots work very hard and spend absolutely unfathomable amounts of money, time, and blood, to make sure that you don't ever realize who's actually taking your money. They do this in the simplest, easiest way. If you simply control information from the top down, and disseminate it when and where you see fit, you can effect great societal change without lifting a finger. Please imagine... really, try to imagine... You just read an article, saw a video, whatever, from a very, very reputable source. And it just informed you that an asteroid was 83% likely to impact the Earth next month. What would you do? What would happen in the world? Hopefully an asteroid will not hit next month, but it's important to really imagine what would happen and why, and how. Because a huge amount of information would be generated and published, people would panic, society would crumble, and the world as you know it would change forever in an instant, the moment you read that headline. Control of information is one of the most powerful tools known to mankind today. A person living in 2020 can easily encounter as much information in a day as someone in Medieval times might have encountered in a lifetime. And it comes at you from all angles, in all forms, non-stop, 24/7. Much like the water in the pipe, the information is always there, and one needs but turn it on. Disseminating the information then becomes a practice all its own, and to be sure, information processing accounts for more than half of the US GDP. And the rate at which it's spread, and way it is handled makes a huge difference in the societal repercussions. So a few different techniques are used:
The "Slow Walk" - If a large, unexpected piece of information is given suddenly, people tend to react poorly and irrationally. Also known as "letting them down easily," this technique restricts the flow of information to prevent the audience from balking or being overwhelmed
The "Steady Drip" - This technique involves keeping your audience subjected to a constant stream of the desired information, so that they become accustomed to it and it becomes "normalized"
The "Firehose" - A deluge of information flying out at full blast, designed to overwhelm the audience so that they cannot focus on anything else
It might be the greatest understatement of all time to say that there has been a lot of information passed around about COVID-19, the "Coronavirus," recently. In fact, there has never been anything like what we are currently experiencing in all of human history, and not by a long shot. And this unprecedented turn of events has caused a lot of people to react in a lot of ways, and say and do a lot of things, for better or for worse. Full disclosure: In particular, if you look up conspiracy theory, you'll see a lot of stuff suggesting that the "Coronavirus is a hoax." (You'll also find a lot of poorly-written rambling) I want to be clear that I DO NOT believe that. I am 100% sure that there is a Coronavirus, that it is making people sick, that a lot of people are dying, and that our medical professionals and many other undervalued workers are overwhelmed, and breaking their backs every day to do their best to keep their friends, families, and loved ones safe. I am extraordinarily grateful for them and admire the resolve and bravery that so many have shown in the face of this disaster. I do not think it is a hoax at all. However, I think that literally everything else that is happening surrounding the "pandemic" is. - - - - - - - - - - - - - - - - - - - - - The Pandemic In the first week of January this year, I got sick. Really sick. I know when I got it and who I got it from, and honestly the exact moment I got it (I only was in proximity of the dude for a few minutes). He had warned me that he was really sick, and I blew it off. I started feeling sick a day or two later, and a day or two after that I felt like I was dying. Fever, chills, aches, extraordinary fatigue. And literal, nonstop, 24/7 coughing. I had every single symptom of what we now know as COVID-19. I commented to anyone who would listen that I didn't recall ever feeling that sick before in my entire life. The most memorable part of it though was that after a couple days, I completely lost my sense of smell and taste. Joked a lot about how you could feed me onions and soap cause I'd have no idea. I try to have a good attitude about being sick. I spent a week sleeping on the couch before I finally went to the doctor. She gave me a Prednisolone steroid pack (which has worked well for me in the past), some Trazodone to knock me out, and Benzonatotate for my cough. As soon as I took the first dose of steroids I started to feel pretty fucking great, and it was more or less a non-issue after that. I spoke to a lot of people about it then and after, and man, I can't tell you how many stories I personally heard from people I know that said the exact same thing. Then I started reading the same story over and over again on Reddit:
We didn't start really hearing about the Coronavirus in the media until the beginning of March, and we didn't hear about the "Pandemic" until just a couple weeks ago. And what a couple weeks it's been since then. But I am quite certain that it's been around for a lot longer and that I, and a lot of other people I know, had it - and DID NOT DIE FROM IT - way back in January. We now know that the first documented case in the US was on January 19th, but that word "documented" is so, so important here. That means that we had identified the virus, developed a test, and tested a person with the symptoms that day. It does NOT mean that was when the virus reached the United States. How sick do you have to be before you take a day off work? Before you go to the doctor? With America's healthcare system or lack thereof, it's almost certain that many people had this virus before we determined what it was, and how infectious it really was. There is also the matter of the statistics of severity vs the regular flu. This is a highly contentious topic and I am no medical expert, and do not wish to make any assertions. However, what I can tell you from my personal experience is this: I had a horrible "flu" in January, got basic medicine, got better. So, either I had the flu, or perhaps I did indeed have the Coronavirus. We will never know because I was never tested. But the important thing is that it doesn't matter. Either I (and many others) had the Coronavirus and it did not kill us (calling into question the severity of the infection) or we just had a bad cold or flu, but it had the exact same symptoms as COVID-19 (calling into question the extent of Coronavirus diagnoses). But logically, one of those two statements is true. Furthermore, the data keeps changing, and I don't mean increasing on a daily basis. I mean up and down, back and forth, it is deadly or maybe it isn't, etc. On January 14 the WHO told you it couldn't spread from human to human. But then on Jan 19 we saw the first case of Coronavirus in the United States. Then it turns out that the Wuhan market outbreak began earlier in December. And then it's an "epidemic," but most people will only get mild symptoms. What are you supposed to believe? And it sure does seem to come at you as a firehose, and it's hard to even think about anything because OHMYGODTHECORONAVIRUS! But let's stop and look a couple basic facts. As a matter of fact, I'm going to let Dr. Sucharit Bhakdi explain this one to you. This is a very informative 10 minute video, watch it: Sucharit Bhakdi - Very clear math showing that the COVID statistics are being manipulated So 80% of people only experience mild symptoms, and we're crashing the economy for this? The statistics aren't any more extreme than many other illnesses we've had over time, and we're crashing the economy for this? It doesn't make sense until you consider that there are other factors besides just the virus at play. Wolfgang Wodard - Explaining how the statistics are being manipulated to cause panic The media, and society at large is inundating you with terrifying information about the Coronavirus. But if it's not as bad as we originally thought, then why? We don't freak out about every illness that comes along, and we've certainly never in the history of civilization had over 1/3 of the global population locked down under mandatory quarantine. And then there's the debate about where the virus came from. We believe it came from a meat market in China, under unsanitary conditions. The science behind a coronavirus making the leap from one species to another is well-established and researched, and it is a very likely scenario. There are also conspiracy theories that state that China released it on its people intentionally, or even that the US military released it in China. Again, we will never know exactly where this Coronavirus came from. It may be natural, it may be man made, and there are very plausible paths for both. I don't know what to believe myself. So here I ask you to make your own judgement based on likelihood. What we do know though is that the state of the world this virus has been unleashed on has played a major factor in its spread. In 1950 the global population was 2.5 billion, and that has exploded to almost 8 billion people in 2020. As a matter of fact, population growth has been exponential since about the time of the Industrial Revolution. With all these people on the planet there are sure to be many disagreements and conflicts, and there indeed have been. As a matter of fact, 2019 saw global protests on an unprecedented scale, in Hong Kong, France, Syria, and many other countries. Citizens have literally been fighting police and military with rocks, clubs, arrows, and molotov cocktails. Did you know that? Despite my seeing headlines and pictures every day of the riots in Hong Kong, I have been shocked to learn that multiple of my close friends, intelligent and aware people, had no knowledge whatsoever of the protests even existing. But that is far from a coincidence; rather, it is quite by design. - - - - - - - - - - - - - - - - - - - - - Billionaires and Coincidences Another major talking point over the last 5 to 10 years has been the "1%" - the handful of super-rich individuals who posess and control the vast majority of the Earth's wealth and resources. Where it used to just be a numerical term, "Billionaire" is now a dirty word, and one of the nastiest. We all hate billionaires. They are evil, and profit off the exploitation of the rest of the world. The "Illuminati" we call them, in pursuit of a "New World Order." Crazy stuff, right? Mysterious symbols and people in black robes doing nefarious things in secret meetings, and running the world from behind the scenes. We love the Illuminati, it's a huge pop culture thing now. The subject of endless speculation, they are made fun of in the media, movies, and now Taco Bell commercials. It's so far fetched it could never really be true. And the fact that you think that is by design as well. So, we don't know where the Coronavirus came from, but it's certainly here, and there are lot of other things unfolding in the world around it. Many different current events from all different places and fields of study. Some of it seems a little too coincidental. It is certainly very coincidental that this economically destructive Coronavirus entered the world right as there were global uprisings, protests in the street, and a growing public hatred for billionaires. Well, here are a few other coincidences: Hundreds of CEOs of major companies stepped down from their positions in recent months. Multiple US Senators sold stock right before the market crashed. Even the boss of the New York Stock Exchange sold his own stock right before the crash. Did they know something they weren't telling us? Here's another coincidence. In 2010, The Rockefeller Foundation published a selection of future-predicting scenarios in the name of "exploring the ways that technology and development could co-evolve." One of these four scenarios, entitled "Lock Step," eerily predicts a global viral pandemic and the resulting hypothetical consequences, which almost exactly mirrors the COVID-19 pandemic we are in the midst of today. Also coincidental: The first case of COVID-19 was diagnosed in China on November 17th, 2019. Literally one month earlier, The Johns Hopkins Center for Health Security in partnership with the World Economic Forum and the Bill and Melinda Gates Foundation hosted Event 201, a high-level pandemic exercise on October 18, 2019, in New York, NY. In this exercise, they discuss the potential implications and consequences of a novel Coronavirus, including an economic crash, martial law, and of particular interest, the control of information. (You can view some published highlights here) The World Economic Forum is comprised of the richest of the rich. The 1%. The Billionaires. CEO's, politicians, business owners, and many other powerful and influential figures. They meet regularly to discuss topics of global concern, and strongly control the dissemination of information. And of primary concern to many of them is maintaining their wealth and power in a rapidly-changing world. And finally, here's one more coincidence: At the exact same time as the Event 201 exercise, The World Military Games was held in Wuhan, China, Oct 18-27, 2019. It was the largest military sports event ever to be held in China, with nearly 10,000 athletes from over 100 countries competing in 27 sports. Wuhan China was, as we now believe, the source of our current global COVID-19 outbreak. Whether you think it is a "conspiracy" or not, that is all certainly coincidental, to say the least. - - - - - - - - - - - - - - - - - - - - - "Why didn't I hear about any of this?" That's an excellent question, and one that likely has multiple answers. For starters, how much do you really pay attention? Where do you get your news from? Do you research things you hear or just accept them on hearsay? Critical thinking skills are paramount in making sense of the chaos unfolding all around us. As I mentioned before, I can tell you that I personally know multiple people who had no clue whatsoever about the riots in Hong Kong last year. As you read this, you may be one of them. And it may seem like something that is happening far away, and "could never happen here." Or you may have been aware of it but just that it was happening. But please, consider for a moment: millions of average citizens risked their lives and safety in the streets of Hong Kong for months on end, fighting police and military, and transforming the city they lived in into a warzone. WHY? Why would people do something like that? Regardless of their motivations, that many people were banding together to fight for something they believed in. And that is worth considering. It's not really your fault though that you may not catch wind of all this news. The "mainstream media" that you hear about all the time deliberately controls information - downplaying threats and overreacting to silly things - in order to make sure that you hear the version of the news that they want you to hear. Did you know that only 6 corporations control 90% of the media In America? That number is reduced from 50 companies in the 80's. And literally all the news you see on TV, at the very least, is 100% owned and controlled by these companies. Lately, distrust is growing for cable news networks, and many people turn to their local hometown station for trusted news. The problem with that though is that your hometown station is probably owned by Sinclair Media, one of the most powerful broadcast networks in the country that you've never heard of. Please watch this very brief video, illustrating the chokehold that Sinclair Media maintains over your nightly local news broadcast: https://www.youtube.com/watch?v=hWLjYJ4BzvI Of course, not every piece of news is pre-programmed but a lot is. The real news is out there, but sometimes you have to look a little deeper than the infographics on TV news. Even if information is being directed from the top down, the boots on the ground tend to be passionate people with a variety of interests and agendas, and they are still doing their best to do real journalism despite corporate oversight. Think of those who are directing the information as steering an impossibly massive ship with a rudder. You can slowly adjust the course of direction, however it is slow to react. If you want to stop, you have to start thinking about stopping wayyy ahead of time. And similarly, once it gets underway, it is then influenced by an inertia all its own. Micro controls and adjustments aren't really possible. Our society is this giant ship. There are 8 billion people on this earth - that is 8000 million. An incomprehensible number that grows rapidly every day. As civilization grows and advances, so does our medicine, our technology, our cultural norms. These are all natural processes that are necessary to manage an increasing number of societies all around the globe. And many of the advances we're making have exciting potential benefits for humanity, although as with all tools, they also inherently possess the potential for abuse. Here are some other things happening in society right now, some you may be aware of and many you may not:
RealID - The Real ID law requires people to show security-enhanced IDs to pass through airport security checkpoints or to enter certain federal facilities.
Traffic Cameras - Most people know that there are traffic cameras in an increasing number of areas, some of which can assess your speed and issue you a ticket automatically.
Automation Everywhere - Beyond assembly lines, robots are continually performing more types of tasks from ever more companies, replacing human employees at an increasing rate.
Automated Trucks - Autonomous trucks are coming soon that can see forward over a half mile, farther than any other autonomous system in the world, and run during the day, the night and even in the rain.
Global Satellite Internet - Elon Musk's SpaceX recently launched its fourth batch of internet-beaming satellites, as the company builds a broadband internet business by deploying thousands of satellites into orbit
Bitcoin and Cryptocurrency - As digital payments become more and more prevalent, digital currency uses cryptography to secure and verify transactions as well as to control the creation of new units of a particular cryptocurrency.
Voluntary Nanochipping - People are having microchips implanted into their bodies so that they don't need to carry key cards, IDs, and even train tickets.
Programmable Viruses - As antibiotic-resistant bacteria becomes a greater problem, viruses are being engineered to fight the bacteria in targeted ways
Facial Recognition Technology - Airports are using facial-recognition cameras to confirm passenger identity. Mobile phone makers are using face recognition for biometric security. Retailers are using it to prevent violence and crime, and for advertising.
Thermal Scanners - Airports, casinos, and grocery stores are screening passengers for sickness. In China, this data is being used to control traffic.
ID2020 - Microsoft co-founder Bill Gates is developing human-implantable capsules that have ‘digital certificates’ which can contain financial data, medical records, tracking tech, and more.
There is an interesting chicken or egg relationship between science fiction and real world science. Sci-fi writers are inspired by the real science of the day, then they apply their creativity to imagine what might be in the future. Young scientists encounter these fantastical ideas and think they are worth pursuing, and then set about to make them a reality, and the cycle continues. Futuristic concepts are then preempted and introduced through the media to the conscious mind, as we include them in books, movies, TV, video games, and more. Eventually we start seeing headlines of these new technologies and developments happening in other places, usually Japan and China first due to their prevalence in the industrial and technological sectors of our global economy. - - - - - - - - - - - - - - - - - - - - -
How ironic that one day everyone began to hear that they were cryptocurrencies, but everything that referred to them was synonymous with Bitcoin everywhere they talk about it, the strange thing is that more than 10 have passed years since this project started and many continue with blindfolds, we have evolved, revolutionary things have come into our lives, the last decades have come technologies that have changed our paradigms, such as the internet and many more came one of them it's bitcoin. Bitcoin arose from the need for a safe, transparent and reliable money. All this is described by Satoshi Nakamoto in his white paper https://www.bitcoin.org/bitcoin.pdf this is at the hand of all so that we can see and read it and know how its structure is shaped and the purpose it has as a currency. Its operation occurred on January 3, 2009, when the genesis block of the chain was published, which was the first block mined in the network, bitcoin turns out to be for the time a magnificent money for the environment that was growing and its use was not long in Expanding its adoption, Hal Finney was one of the first people to support and contribute with Bitcoin since it was part of one of the first nodes, bitcoin has a maximum number of bitcoins that can be created on the network which is 21 million BTC Being this way it solves the problem of inflation since it is a deflationary currency, this system means that no more can be generated and its value will rise more over time due to the supply and demand that there will be in the market. Every time a transaction is made there will be a number of validators that work to verify that the network is correct, this is through the blockchain is the accounting book where all the transactions made from the genesis block are stored , it is public and we can all see how it works that they do not draw cards up their sleeves, these blocks are mined every 10 minutes with a size of 1 mb approximately 2048 transactions that were made and will be mined by a very important group called miners who solve a mathematical process called proof of work with this will be the final process for your BTC sent will already be in the hands of its recipient. To make a transaction you only need the address to which you want to send BTC or the QR code to be faster and select the amount in your wallet, with this you will only have to pay a commission for the work carried out by the miners that can vary depending on the time with which you want your transaction to be verified or to be mined in the next block of the chain. Today Bitcoin is the most important currency in the entire market with a strong ecosystem and a very large community that grows more for the security it offers, its price when making this post reaches $ 9,342.58 and a market capitalization of 168,004,364,619, $ 45 with which it takes the number 1 spot on the coinmarketCap list. original post.

Cryptocurrency exchanges process over $20 billion in trade volume per day. Most of the transactions are going through centralized exchanges, where the users need to fully trust them for managing their assests and transactions. However, the risk of trusting these centralized exchanges has also been seen. For example, QuadrigaCX, which was the largest cryptocurrency exchange in Canada, lost $19 million of their customers' assets . Decentralized Exchanges (DEXes) have been introduced to address this problem -- they allow traders to purchase and sell cryptocurrencies in a peer-to-peer manner, so no involvement of any trusted party is required. Atomic Swap is one of the promising technology for implementing a DEX. While it enables pure peer to peer trading, it also introduces problems such as unfairness and long confirmation latency. While existing work  has provided a solution towards a fair atomic swap protocol, the issue of long confirmation latency is inherent. Another promising direction is leveraging liquidity pools. With liquidity pools, pairs of assets are reserved for trading. For any pair of assets supported by the liquidity pool, traders can exchange their assets without any third party. As traders can only perform the transactions if there are reserved assets, one core problem is how to attract liquidity providers to provide liquidity by reserving assets. It is not difficult to see that incentive [3,4], which has been a key component of all permissionless blockchains, can be equipped to incentivize liqudity providers. However, flawed incentive designs will lead to attacks and other concerns [5-13]. There are two main types of incentive designs, namely "trans-fee mining" and "liquidity mining". They are different from the Proof-of-X mining in blockchains for reaching consensus (a detailed analysis can be found in the survey ). Rather, they are used to incentivise users to join the ecosystem. "Trans-fee mining" was proposed by FCoin in 2018 . With FCoin, each time a transaction is created, 100% of its transaction fee will be returned in FCoin token to the payer as a reward. This is one incentive design to encourage traders to join the system. However, as FCoin may have no value to the trader, FCoin also introduces extra reward to all coin holders -- 80% of the transaction fee in its native currency (such as ETH) will be distributed to all coin holders. So, traders are incentivized to join the system, becoming a holder of FCoin token, and obtaining a share of the transaction fee of every transaction in the FCoin ecosystem. While this had successful attracted traders, it is not sustainable. Rather than charging a trader to perform transactions, FCoin rewards traders. Profit-driven traders will create transactions at full speed to earn FCoin token and the share as a token holder. Indeed, the trading volume of FCoin was the top one among all exchange services, and the daily reward can be as high as 6000 BTC . However, once all coins are minted, then the system would lose liveness as there is not enough supply to be distributed. "Liquidity mining" aims at giving reward to the liquidity providers rather than the traders. There are different ways to implement liquidity mining. Compound  is a famous example of protocols deploying liquidity mining. With Compound, users become a liquidity provider by supply assets to a pool and obtain interests for its contribution (similar to depositing money into a bank). Liquidity providers first reserve some assets in the pool and obtain "cToken" of Compound which entitles the owner to an increasing quantity of the underlying asset. Users can use their "cToken" to borrow different assets available on the Compound and pay some interests to Compund. The borrowers may have some quick gains through the financial games . Both borrowers and liquidity providers can withdraw their asset by trading them back with "cToken". Oners of "cToken" can also manage the business direction and decisions of Compound through weighted voting. The potential concern here is that rich users might be able to take over the control of the system. Uniswap  is another popular DEX deploying liquidity mining. Uniswap incentivizes liquidity providers by giving them a share of the earned transaction fees. In particular, Uniswap changes each transaction a 0.3% fee, where 0.25% will be distributed to the liquidity providers, and 0.05% will go to the Uniswap account. One issue is how to incentivize traders. With Uniswap, traders are incentivized by the potential profit it can gain through the price difference between Uniswap and other exchanges. Uniswap price oracle is based on a constant function market makers [20,21], where the product of the number of reserved tokens is a constant. For example, if Uniswap has a pair of X token A and Y token B, then when a user using X' token A to buy Y' token B, the product of the reserved number of tokens should remain the same, i.e., XY = (X+X')(Y-Y'). The price of Uniswap (V1) is also defined in this way. This allows traders to speculate in the exchange market as the asset price on Uniswap is changed dynamically and is different from other exchanges. This, on the other hand, may have a security risk as the price can be easily manipulated. Uniswap (V2) fixed this problem by taking an accumulated price over a period of time . However, as speculation/manipulation becomes harder, the trading volume may decrease. MiniSwap  introduces a hybrid model (a mixture of "trans-fee mining" and "liquidity mining") to address the above issues. MiniSwap provides three types of rewards. For each trade with transaction fee f ETH in MiniSwap, a number of MiniSwap tokens (called MINI) worth 2f ETH will be minted. A (parameterized) portion of the tokens are given to the trader, and the rest are distribued to the liqudity providers. The transaction fee (f ETH) is used to exchange MINI in the liquidity pool. 50% of the obtained MINI will be distributed to all MINI holders, and the other 50% will be destroyed. In this way, both traders and liquidity providers are incentivized to join the ecosystem. Recall that with FCoin, there is a problem when all coins are minted. MiniSwap has an upper bound (of 500,000 tokens) on the number of tokens can be created every day, and this limit reduces every month until a point where the limit (18,000 tokens) remains unchanged. This guarantees the sustainability of the system as the mining process can last for 100 years. The parameterized ratio of tokens as the reward to the trader and liquidity provider can also strengthen sustainability. It enables the system to dynamically balance the incentive of different parties in the system to make it more sustainable. Overall, the MiniSwap hybrid model has taken the benefit of both "trans-fee mining" model and "liquidity mining" model, while eliminated the potential concerns. Formally defining and analyzing these models, e.g. through the game-theoretic approach , would be an interesting direction.

The dominance of the blockchain and the crypto currency is not a joke or a fantasy, because the growth and its importance to the world in general is easily accessible and observable by all in the whole world. Take another instance, and observe the rate of massive adoption of the blockchain and crypto currency by people of different countries using bitcoin as an alternative payment system, integrating ripple with banking services, and also with the aid of smart contracts helping several ecosystems in the blockchain world today. But do you know that most blockchain platforms are centralized when it comes to your data and information; and this betrays the blockchain ideology on all grounds, several projects have tried to conceal the data, records and identities of several users; and it deserves a better blockchain to do that which is why Arcs fits the Task. https://preview.redd.it/9pw49kv62xb51.png?width=842&format=png&auto=webp&s=83590bee23cb5a2f05a5972c96c6849aa2aa9050 What is Arcs? Arcs is providing the whole blockchain system a new world token and a blockchain ecosystem in Alre; Alre is a blockchain ecosystem that provides the entire platform functionality for management and storing of different various data structures, which are essential to businesses and to also monetize data. Monetize data also means earning from storing datas. And to make the alre platform very functional, the arcs token comes to aid; the arcs token will help the platform achieve non centralized system by operating in a unique way. How does the Alre Ecosystem operate? The Alre Ecosystem is operated to work based on 3 functionalities; The functionalities provide the system a flexible framework; that makes it easy for companies, industries t build their system scenarios and application, as well as store their data with powerful insights from the data analytics. The 3 functionalities of the Alre Ecosystem are;
Information input; This is where data, information of individuals or companies are received into the alre platform. The data requested to be inputted will include gender, address, questionairres answers, blog texts and profile links to social media accounts. The interesting facts is that the Alre is designed using the Internet of Things IoT blockchain and the Artificial Intelligence AI functions to store personal details, health details and location details with the consent of the user, as you input your details to be stored safely on the Alre ecosystem, you receive the arcs token as an incentive.
Information storage; The Alre system calculates the has values for every inputted data and stores it on the blockchain platform automatically. This process ensures that the integrity of the platform is protected and also ensures that data are always verified and never tampered with.
Information utilization; One of the important features of the Alre platform is that it allows companies to integrate their businesses and applications and even offer their own data bank services.
Today we will briefly open the curtain on a secret that we have kept secret for more than 2.5 years. Fascinating, isn’t it? Yes, it was a difficult burden for us to keep secret the trumps that we wanted to tell about. Getting criticized, misunderstood by investors while making a very global financial infrastructure. And we can understand all those who did not understand our strategy because due to the confidentiality of the infrastructure, which will be available soon, we had to keep secret all the advantages of the TKEY platform, all the development processes, and make various strategies to calmly finish what we started.
What is this mysterious infrastructure?
When we created the first concept of Tkeycoin — we clearly understood that a system should be developed that will provide users around the world with easy and fast work with finances. Here we are not only talking about the user segment, but we are also talking about more global segments, such as the global financial system, which can be used by millions of people and corporations around the world. At the same time, we clearly understood and understand that there are many different tools in the world, and all of them are good in their way, including SWIFT or Bitcoin, they all have their advantages and scope. But, TKEY is not about Bitcoin or SWIFT. Remember our words?
To create something more than a cryptocurrency, you need time, money, knowledge, experience, and radically different views of the world. We are here to create an infrastructure for working with Finance. Based on this system, we can provide people with investment tools, rapid exchange of assets around the world, provide our users with new revenue generation mechanisms, offer the corporate segment effective use of their assets, and the public sector — improve data exchange. That’s why we developed — TkeyNet.
TkeyNet is a new branch in the world of financial technologies
First of all, TkeyNet is an infrastructure based on which you can create various microservices, applications, financial instruments, exchanges, investment products, work with smart contracts, create your assets in various branches of TkeyNet, and much more. Second of all, TkeyNet is a set of solutions focused on payment systems and operations with instant currency exchange in an international format. TkeyNet software solutions allow you to make instant money transfers to any point in the world, as well as act as a reliable storage of amounts of various denominations. TkeyNet was conceived from the beginning of 2018 — the project was kept in the strictest secrecy and its development was carried out by a separate team of developers together with foreign programmers. In 2018, the necessary funding was received to develop the entire TkeyNet system. The development period set for us was at least 2.5–3 years. Taking into account the long development period of TkeyNet, we have drawn up an internal roadmap and decided to release the intermediate Core 1.0 Protocol with subsequent release to the exchange in 2019. The plan was as follows:
Core 1.0 release — listing on the stock exchange in 2019 to attract a new audience and create liquidity for the TKEY digital asset.
Updates from Core 1.0 to Core 2.0 for a smooth transition to TkeyNet when the TKEY digital asset is already being traded on the exchange.
The transition to TkeyNet to strengthen market position and scale the project.
In simple words, the full version of Core 2.0-would allows us to switch to TkeyNet during trading, without further stopping the entire network.
The first references to TkeyNet were presented by us in 2018 on the platform’s websites and in the first editions of the “white paper”, and the first presentation took place in the period from April 18–21, 2019 at the Asian parliamentary Assembly (APA), where TKey’s management presented the TkeyNet system during closed presentations.
In 2019, we actively tested the system and held closed meetings with representatives of large businesses. The system was known only to the management of some of the major companies and trusted persons. This helped keep all the company’s plans completely secret.
Given the current situation and the almost complete completion of work on TkeyNet, as well as the upcoming listing, we made an operational decision to quickly switch to the new system. After all, the more users in the project, the more difficult it is to implement global changes, and even more so when assets are already traded on the exchange. But this is not the most important thing — these are only indirect reasons that affected the upgrade to TkeyNet. The FINTECH market is developing at a tremendous speed, with products that are already embedded in TkeyNet and its technical characteristics — we will actively stand out in the market. TkeyNet already has built-in features that make it easy to compete with other projects, also, the following products based on TkeyNet will be available this year, which will further strengthen our position in the digital market. Yes, this is a chance that should not be missed. Why not switch to TkeyNet now? Only forward! “that’s our motto. Since last week, we have been working on active and final work to fully launch TkeyNet, so it takes time to debug all the processes. We ask all users to adhere to our recommendations and wait for a little, because it’s worth the wait, and you will see for yourself when TkeyNet is launched. After the release of TkeyNet — we will tell you in detail what it can do, how it works, but most importantly, you will see how it works. TkeyNet — will is available to all users in Mainnet\* and Testnet\*.
Mainnetis a complete product, ready to use.Testnetis an alternative blockchain (test network) that is used for testing.
After the launch of TkeyNet and integration with the exchange, there will be a long-awaited listing of Tkeycoin.

Bitcoin works exactly like the notebook example. Each Bitcoin user has an identical copy of the Bitcoin “notebook” which publicly records all transactions. All notebooks get constantly compared to make sure they match. Additionally, Bitcoin stores all past transactions permanently so that there is a record of where all bitcoin currently are.
