The problem of scalability in the Bitcoin network ...

Ultimate glossary of crypto currency terms, acronyms and abbreviations

I thought it would be really cool to have an ultimate guide for those new to crypto currencies and the terms used. I made this mostly for beginner’s and veterans alike. I’m not sure how much use you will get out of this. Stuff gets lost on Reddit quite easily so I hope this finds its way to you. Included in this list, I have included most of the terms used in crypto-communities. I have compiled this list from a multitude of sources. The list is in alphabetical order and may include some words/terms not exclusive to the crypto world but may be helpful regardless.
2FA
Two factor authentication. I highly advise that you use it.
51% Attack:
A situation where a single malicious individual or group gains control of more than half of a cryptocurrency network’s computing power. Theoretically, it could allow perpetrators to manipulate the system and spend the same coin multiple times, stop other users from completing blocks and make conflicting transactions to a chain that could harm the network.
Address (or Addy):
A unique string of numbers and letters (both upper and lower case) used to send, receive or store cryptocurrency on the network. It is also the public key in a pair of keys needed to sign a digital transaction. Addresses can be shared publicly as a text or in the form of a scannable QR code. They differ between cryptocurrencies. You can’t send Bitcoin to an Ethereum address, for example.
Altcoin (alternative coin): Any digital currency other than Bitcoin. These other currencies are alternatives to Bitcoin regarding features and functionalities (e.g. faster confirmation time, lower price, improved mining algorithm, higher total coin supply). There are hundreds of altcoins, including Ether, Ripple, Litecoin and many many others.
AIRDROP:
An event where the investors/participants are able to receive free tokens or coins into their digital wallet.
AML: Defines Anti-Money Laundering laws**.**
ARBITRAGE:
Getting risk-free profits by trading (simultaneous buying and selling of the cryptocurrency) on two different exchanges which have different prices for the same asset.
Ashdraked:
Being Ashdraked is essentially a more detailed version of being Zhoutonged. It is when you lose all of your invested capital, but you do so specifically by shorting Bitcoin. The expression “Ashdraked” comes from a story of a Romanian cryptocurrency investor who insisted upon shorting BTC, as he had done so successfully in the past. When the price of BTC rose from USD 300 to USD 500, the Romanian investor lost all of his money.
ATH (All Time High):
The highest price ever achieved by a cryptocurrency in its entire history. Alternatively, ATL is all time low
Bearish:
A tendency of prices to fall; a pessimistic expectation that the value of a coin is going to drop.
Bear trap:
A manipulation of a stock or commodity by investors.
Bitcoin:
The very first, and the highest ever valued, mass-market open source and decentralized cryptocurrency and digital payment system that runs on a worldwide peer to peer network. It operates independently of any centralized authorities
Bitconnect:
One of the biggest scams in the crypto world. it was made popular in the meme world by screaming idiot Carlos Matos, who infamously proclaimed," hey hey heeeey” and “what's a what's a what's up wasssssssssuuuuuuuuuuuuup, BitConneeeeeeeeeeeeeeeeeeeeeeeect!”. He is now in the mentally ill meme hall of fame.
Block:
A package of permanently recorded data about transactions occurring every time period (typically about 10 minutes) on the blockchain network. Once a record has been completed and verified, it goes into a blockchain and gives way to the next block. Each block also contains a complex mathematical puzzle with a unique answer, without which new blocks can’t be added to the chain.
Blockchain:
An unchangeable digital record of all transactions ever made in a particular cryptocurrency and shared across thousands of computers worldwide. It has no central authority governing it. Records, or blocks, are chained to each other using a cryptographic signature. They are stored publicly and chronologically, from the genesis block to the latest block, hence the term blockchain. Anyone can have access to the database and yet it remains incredibly difficult to hack.
Bullish:
A tendency of prices to rise; an optimistic expectation that a specific cryptocurrency will do well and its value is going to increase.
BTFD:
Buy the fucking dip. This advise was bestowed upon us by the gods themselves. It is the iron code to crypto enthusiasts.
Bull market:
A market that Cryptos are going up.
Consensus:
An agreement among blockchain participants on the validity of data. Consensus is reached when the majority of nodes on the network verify that the transaction is 100% valid.
Crypto bubble:
The instability of cryptocurrencies in terms of price value
Cryptocurrency:
A type of digital currency, secured by strong computer code (cryptography), that operates independently of any middlemen or central authoritie
Cryptography:

When HODLers(holders) eventually cash out they go to a place called crypto-Valhalla. The strong will be separated from the weak and the strong will then be given lambos.
DAO:
Decentralized Autonomous Organizations. It defines A blockchain technology inspired organization or corporation that exists and operates without human intervention.
Dapp (decentralized application):
An open-source application that runs and stores its data on a blockchain network (instead of a central server) to prevent a single failure point. This software is not controlled by the single body – information comes from people providing other people with data or computing power.
Decentralized:
A system with no fundamental control authority that governs the network. Instead, it is jointly managed by all users to the system.
Desktop wallet:
A wallet that stores the private keys on your computer, which allow the spending and management of your bitcoins.
DILDO:
Long red or green candles. This is a crypto signal that tells you that it is not favorable to trade at the moment. Found on candlestick charts.
Digital Signature:
An encrypted digital code attached to an electronic document to prove that the sender is who they say they are and confirm that a transaction is valid and should be accepted by the network.

Fiat money:
Fiat currency is legal tender whose value is backed by the government that issued it, such as the US dollar or UK pound.
Fork:
A split in the blockchain, resulting in two separate branches, an original and a new alternate version of the cryptocurrency. As a single blockchain forks into two, they will both run simultaneously on different parts of the network. For example, Bitcoin Cash is a Bitcoin fork.
FOMO:

Frictionless:
A system is frictionless when there are zero transaction costs or trading retraints.
FUD:
Fear, Uncertainty and Doubt regarding the crypto market.
Gas:
A fee paid to run transactions, dapps and smart contracts on Ethereum.
Halving:

Lambo:
This stands for Lamborghini. A small meme within the investing community where the moment someone gets rich they spend their earnings on a lambo. One day we will all have lambos in crypto-valhalla.
Ledger:
Away from Blockchain, it is a book of financial transactions and balances. In the world of crypto, the blockchain functions as a ledger. A digital currency’s ledger records all transactions which took place on a certain block chain network.
Leverage:
Trading with borrowed capital (margin) in order to increase the potential return of an investment.

Pre mining:
The mining of a cryptocurrency by its developers before it is released to the public.
Proof of stake (POS):
A consensus distribution algorithm which essentially rewards you based upon the amount of the coin that you own. In other words, more investment in the coin will leads to more gain when you mine with this protocol In Proof of Stake, the resource held by the “miner” is their stake in the currency.
PROOF OF WORK (POW) :
The competition of computers competing to solve a tough crypto math problem. The first computer that does this is allowed to create new blocks and record information.” The miner is then usually rewarded via transaction fees.
Protocol:
A standardized set of rules for formatting and processing data.
Public key / private key:
A cryptographic code that allows a user to receive cryptocurrencies into an account. The public key is made available to everyone via a publicly accessible directory, and the private key remains confidential to its respective owner. Because the key pair is mathematically related, whatever is encrypted with a public key may only be decrypted by its corresponding private key.

Satoshi Nakamoto:
This was the pseudonym for the mysterious creator of Bitcoin.
Scalability:
The ability of a cryptocurrency to contain the massive use of its Blockchain.
Sharding:
A scaling solution for the Blockchain. It is generally a method that allows nodes to have partial copies of the complete blockchain in order to increase overall network performance and consensus speeds.

Surge:
When a crypto currency appreciates or goes up in price.
Tank:
The opposite of mooning. When a coin tanks it can also be described as crashing.
Tendies
For traders , the chief prize is “tendies” (chicken tenders, the treat an overgrown man-child receives for being a “Good Boy”) .
Token:
A unit of value that represents a digital asset built on a blockchain system. A token is usually considered as a “coin” of a cryptocurrency, but it really has a wider functionality.
TOR: “The Onion Router” is a free web browser designed to protect users’ anonymity and resist censorship. Tor is usually used surfing the web anonymously and access sites on the “Darkweb”.
Transaction fee:
An amount of money users are charged from their transaction when sending cryptocurrencies.
Volatility:
A measure of fluctuations in the price of a financial instrument over time. High volatility in bitcoin is seen as risky since its shifting value discourages people from spending or accepting it.

Bitcoin Newcomers FAQ - Please read!

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Some other great resources include Lopp.net, the Princeton crypto series and James D'Angelo's Bitcoin 101 Blackboard series.
Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute.
Some Bitcoin statistics can be found here and here. Developer resources can be found here. Peer-reviewed research papers can be found here.
Potential upcoming protocol improvements and scaling resources here and here.
The number of times Bitcoin was declared dead by the media can be found here (LOL!)

Key properties of Bitcoin

Where can I buy bitcoins?

Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Google Auth Authy OTP Auth
Android Android N/A
iOS iOS iOS

Watch out for scams

As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".

Where can I spend bitcoins?

Check out spendabit or bitcoin directory for millions of merchant options. Also you can spend bitcoin anywhere visa is accepted with bitcoin debit cards such as the CashApp card. Some other useful site are listed below.

There are also lots of charities which accept bitcoin donations.

Merchant Resources

There are several benefits to accepting bitcoin as a payment option if you are a merchant;
If you are interested in accepting bitcoin as a payment method, there are several options available;

Can I mine bitcoin?

Mining bitcoins can be a fun learning experience, but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read more here. Still have mining questions? The crew at /BitcoinMining would be happy to help you out.
If you want to contribute to the bitcoin network by hosting the blockchain and propagating transactions you can run a full node using this setup guide. If you would prefer to keep it simple there are several good options. You can view the global node distribution here.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
bitcoin BTC 1 bitcoin one bitcoin is equal to 100 million satoshis
millibitcoin mBTC 1,000 per bitcoin used as default unit in recent Electrum wallet releases
bit bit 1,000,000 per bitcoin colloquial "slang" term for microbitcoin (μBTC)
satoshi sat 100,000,000 per bitcoin smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $10000 for one Bitcoin, a $10 meal would equal:

Focused discussion: What is the most promising peer-to-peer decentralised cash system?

While this subreddit is called /cryptocurrency, we obviously talk about a lot of other functions of cryptocoins than the currency aspect. I’d however like to have a discussion on what the best cryptocurrency is that we currently have, and would love to hear your arguments why. The way I see it, there are a few important aspects of a cryptocurrency, as also delineated by Satoshi Nakamoto (1 and 2) while there are also aspects of a currency in general that must be satisfied (3 and 4).
  1. To be a cryptocurrency it has to be decentralised, to rely on cryptographic proof rather than trust. If there is one entity validating the transactions of a cryptocurrency, it can hardly be called a cryptocurrency. Source: Bitcoin whitepaper
  2. The value of it must not be pegged to a fiat currency. A centralised cryptocurrency, one whose value is determined by a central authority (such as Tether), is a contradiction in terminis. Source: Satoshi Nakamoto
  3. Transferability. This is an obvious point, but an important one. Being transferrable is on the one hand a clear-cut definition, but is on the other hand a scale rather than an absolute yes or no. Ceteris paribus, the lower the barrier is to transacting in a currency, the higher the potential velocity of money is. I would say this actually consists of a few sub-categories: transaction speed, transaction cost, ease of use and acceptance of the currency.
  4. Scalability. Another obvious one: if a cryptocurrency can only do one transaction per hour, it's never going to be useful as a broadly used currency.
My question to you is: What cryptocurrency do you think best fits the definition of the ultimate cryptocurrency, and why? Are there aspects of being a currency that I missed that you feel are important to have for a currency? Do you think any cryptocurrency at all is able to act as a currency for a full country, let alone for the entire world? Do you feel like we'll never be able to get a decentralised currency anyway?
Edit: in case it wasn't clear, the thread title is the original tagline that Satoshi chose for Bitcoin from the whitepaper.

Comparison between Avalanche, Cosmos and Polkadot

Comparison between Avalanche, Cosmos and Polkadot
Reposting after was mistakenly removed by mods (since resolved - Thanks)
A frequent question I see being asked is how Cosmos, Polkadot and Avalanche compare? Whilst there are similarities there are also a lot of differences. This article is not intended to be an extensive in-depth list, but rather an overview based on some of the criteria that I feel are most important.
For better formatting see https://medium.com/ava-hub/comparison-between-avalanche-cosmos-and-polkadot-a2a98f46c03b
https://preview.redd.it/e8s7dj3ivpq51.png?width=428&format=png&auto=webp&s=5d0463462702637118c7527ebf96e91f4a80b290

Overview

Cosmos

Cosmos is a heterogeneous network of many independent parallel blockchains, each powered by classical BFT consensus algorithms like Tendermint. Developers can easily build custom application specific blockchains, called Zones, through the Cosmos SDK framework. These Zones connect to Hubs, which are specifically designed to connect zones together.
The vision of Cosmos is to have thousands of Zones and Hubs that are Interoperable through the Inter-Blockchain Communication Protocol (IBC). Cosmos can also connect to other systems through peg zones, which are specifically designed zones that each are custom made to interact with another ecosystem such as Ethereum and Bitcoin. Cosmos does not use Sharding with each Zone and Hub being sovereign with their own validator set.
For a more in-depth look at Cosmos and provide more reference to points made in this article, please see my three part series — Part One, Part Two, Part Three
(There's a youtube video with a quick video overview of Cosmos on the medium article - https://medium.com/ava-hub/comparison-between-avalanche-cosmos-and-polkadot-a2a98f46c03b)

Polkadot

Polkadot is a heterogeneous blockchain protocol that connects multiple specialised blockchains into one unified network. It achieves scalability through a sharding infrastructure with multiple blockchains running in parallel, called parachains, that connect to a central chain called the Relay Chain. Developers can easily build custom application specific parachains through the Substrate development framework.
The relay chain validates the state transition of connected parachains, providing shared state across the entire ecosystem. If the Relay Chain must revert for any reason, then all of the parachains would also revert. This is to ensure that the validity of the entire system can persist, and no individual part is corruptible. The shared state makes it so that the trust assumptions when using parachains are only those of the Relay Chain validator set, and no other. Interoperability is enabled between parachains through Cross-Chain Message Passing (XCMP) protocol and is also possible to connect to other systems through bridges, which are specifically designed parachains or parathreads that each are custom made to interact with another ecosystem such as Ethereum and Bitcoin. The hope is to have 100 parachains connect to the relay chain.
For a more in-depth look at Polkadot and provide more reference to points made in this article, please see my three part series — Part One, Part Two, Part Three
(There's a youtube video with a quick video overview of Polkadot on the medium article - https://medium.com/ava-hub/comparison-between-avalanche-cosmos-and-polkadot-a2a98f46c03b)

Avalanche

Avalanche is a platform of platforms, ultimately consisting of thousands of subnets to form a heterogeneous interoperable network of many blockchains, that takes advantage of the revolutionary Avalanche Consensus protocols to provide a secure, globally distributed, interoperable and trustless framework offering unprecedented decentralisation whilst being able to comply with regulatory requirements.
Avalanche allows anyone to create their own tailor-made application specific blockchains, supporting multiple custom virtual machines such as EVM and WASM and written in popular languages like Go (with others coming in the future) rather than lightly used, poorly-understood languages like Solidity. This virtual machine can then be deployed on a custom blockchain network, called a subnet, which consist of a dynamic set of validators working together to achieve consensus on the state of a set of many blockchains where complex rulesets can be configured to meet regulatory compliance.
Avalanche was built with serving financial markets in mind. It has native support for easily creating and trading digital smart assets with complex custom rule sets that define how the asset is handled and traded to ensure regulatory compliance can be met. Interoperability is enabled between blockchains within a subnet as well as between subnets. Like Cosmos and Polkadot, Avalanche is also able to connect to other systems through bridges, through custom virtual machines made to interact with another ecosystem such as Ethereum and Bitcoin.
For a more in-depth look at Avalanche and provide more reference to points made in this article, please see here and here

This article is not intended to be an extensive in-depth list, but rather an overview based on some of the criteria that I feel are most important. For a more in-depth view I recommend reading the articles for each of the projects linked above and coming to your own conclusions. I want to stress that it’s not a case of one platform being the killer of all other platforms, far from it. There won’t be one platform to rule them all, and too often the tribalism has plagued this space. Blockchains are going to completely revolutionise most industries and have a profound effect on the world we know today. It’s still very early in this space with most adoption limited to speculation and trading mainly due to the limitations of Blockchain and current iteration of Ethereum, which all three of these platforms hope to address. For those who just want a quick summary see the image at the bottom of the article. With that said let’s have a look

Each Zone and Hub in Cosmos is capable of up to around 1000 transactions per second with bandwidth being the bottleneck in consensus. Cosmos aims to have thousands of Zones and Hubs all connected through IBC. There is no limit on the number of Zones / Hubs that can be created

Polkadot

Parachains in Polkadot are also capable of up to around 1500 transactions per second. A portion of the parachain slots on the Relay Chain will be designated as part of the parathread pool, the performance of a parachain is split between many parathreads offering lower performance and compete amongst themselves in a per-block auction to have their transactions included in the next relay chain block. The number of parachains is limited by the number of validators on the relay chain, they hope to be able to achieve 100 parachains.

Avalanche

Avalanche is capable of around 4500 transactions per second per subnet, this is based on modest hardware requirements to ensure maximum decentralisation of just 2 CPU cores and 4 GB of Memory and with a validator size of over 2,000 nodes. Performance is CPU-bound and if higher performance is required then more specialised subnets can be created with higher minimum requirements to be able to achieve 10,000 tps+ in a subnet. Avalanche aims to have thousands of subnets (each with multiple virtual machines / blockchains) all interoperable with each other. There is no limit on the number of Subnets that can be created.

Results

All three platforms offer vastly superior performance to the likes of Bitcoin and Ethereum 1.0. Avalanche with its higher transactions per second, no limit on the number of subnets / blockchains that can be created and the consensus can scale to potentially millions of validators all participating in consensus scores ✅✅✅. Polkadot claims to offer more tps than cosmos, but is limited to the number of parachains (around 100) whereas with Cosmos there is no limit on the number of hubs / zones that can be created. Cosmos is limited to a fairly small validator size of around 200 before performance degrades whereas Polkadot hopes to be able to reach 1000 validators in the relay chain (albeit only a small number of validators are assigned to each parachain). Thus Cosmos and Polkadot scores ✅✅

Decentralisation

Cosmos

Tendermint consensus is limited to around 200 validators before performance starts to degrade. Whilst there is the Cosmos Hub it is one of many hubs in the network and there is no central hub or limit on the number of zones / hubs that can be created.

Polkadot

Polkadot has 1000 validators in the relay chain and these are split up into a small number that validate each parachain (minimum of 14). The relay chain is a central point of failure as all parachains connect to it and the number of parachains is limited depending on the number of validators (they hope to achieve 100 parachains). Due to the limited number of parachain slots available, significant sums of DOT will need to be purchased to win an auction to lease the slot for up to 24 months at a time. Thus likely to lead to only those with enough funds to secure a parachain slot. Parathreads are however an alternative for those that require less and more varied performance for those that can’t secure a parachain slot.

Avalanche

Avalanche consensus scan scale to tens of thousands of validators, even potentially millions of validators all participating in consensus through repeated sub-sampling. The more validators, the faster the network becomes as the load is split between them. There are modest hardware requirements so anyone can run a node and there is no limit on the number of subnets / virtual machines that can be created.

Results

Avalanche offers unparalleled decentralisation using its revolutionary consensus protocols that can scale to millions of validators all participating in consensus at the same time. There is no limit to the number of subnets and virtual machines that can be created, and they can be created by anyone for a small fee, it scores ✅✅✅. Cosmos is limited to 200 validators but no limit on the number of zones / hubs that can be created, which anyone can create and scores ✅✅. Polkadot hopes to accommodate 1000 validators in the relay chain (albeit these are split amongst each of the parachains). The number of parachains is limited and maybe cost prohibitive for many and the relay chain is a ultimately a single point of failure. Whilst definitely not saying it’s centralised and it is more decentralised than many others, just in comparison between the three, it scores ✅

Latency

Cosmos

Tendermint consensus used in Cosmos reaches finality within 6 seconds. Cosmos consists of many Zones and Hubs that connect to each other. Communication between 2 zones could pass through many hubs along the way, thus also can contribute to latency times depending on the path taken as explained in part two of the articles on Cosmos. It doesn’t need to wait for an extended period of time with risk of rollbacks.

Polkadot

Polkadot provides a Hybrid consensus protocol consisting of Block producing protocol, BABE, and then a finality gadget called GRANDPA that works to agree on a chain, out of many possible forks, by following some simpler fork choice rule. Rather than voting on every block, instead it reaches agreements on chains. As soon as more than 2/3 of validators attest to a chain containing a certain block, all blocks leading up to that one are finalized at once.
If an invalid block is detected after it has been finalised then the relay chain would need to be reverted along with every parachain. This is particularly important when connecting to external blockchains as those don’t share the state of the relay chain and thus can’t be rolled back. The longer the time period, the more secure the network is, as there is more time for additional checks to be performed and reported but at the expense of finality. Finality is reached within 60 seconds between parachains but for external ecosystems like Ethereum their state obviously can’t be rolled back like a parachain and so finality will need to be much longer (60 minutes was suggested in the whitepaper) and discussed in more detail in part three

Avalanche

Avalanche consensus achieves finality within 3 seconds, with most happening sub 1 second, immutable and completely irreversible. Any subnet can connect directly to another without having to go through multiple hops and any VM can talk to another VM within the same subnet as well as external subnets. It doesn’t need to wait for an extended period of time with risk of rollbacks.

Results

With regards to performance far too much emphasis is just put on tps as a metric, the other equally important metric, if not more important with regards to finance is latency. Throughput measures the amount of data at any given time that it can handle whereas latency is the amount of time it takes to perform an action. It’s pointless saying you can process more transactions per second than VISA when it takes 60 seconds for a transaction to complete. Low latency also greatly increases general usability and customer satisfaction, nowadays everyone expects card payments, online payments to happen instantly. Avalanche achieves the best results scoring ✅✅✅, Cosmos with comes in second with 6 second finality ✅✅ and Polkadot with 60 second finality (which may be 60 minutes for external blockchains) scores ✅

Shared Security

Cosmos

Every Zone and Hub in Cosmos has their own validator set and different trust assumptions. Cosmos are researching a shared security model where a Hub can validate the state of connected zones for a fee but not released yet. Once available this will make shared security optional rather than mandatory.

Polkadot

Shared Security is mandatory with Polkadot which uses a Shared State infrastructure between the Relay Chain and all of the connected parachains. If the Relay Chain must revert for any reason, then all of the parachains would also revert. Every parachain makes the same trust assumptions, and as such the relay chain validates state transition and enables seamless interoperability between them. In return for this benefit, they have to purchase DOT and win an auction for one of the available parachain slots.
However, parachains can’t just rely on the relay chain for their security, they will also need to implement censorship resistance measures and utilise proof of work / proof of stake for each parachain as well as discussed in part three, thus parachains can’t just rely on the security of the relay chain, they need to ensure sybil resistance mechanisms using POW and POS are implemented on the parachain as well.

Avalanche

A subnet in Avalanche consists of a dynamic set of validators working together to achieve consensus on the state of a set of many blockchains where complex rulesets can be configured to meet regulatory compliance. So unlike in Cosmos where each zone / hub has their own validators, A subnet can validate a single or many virtual machines / blockchains with a single validator set. Shared security is optional

Results

Shared security is mandatory in polkadot and a key design decision in its infrastructure. The relay chain validates the state transition of all connected parachains and thus scores ✅✅✅. Subnets in Avalanche can validate state of either a single or many virtual machines. Each subnet can have their own token and shares a validator set, where complex rulesets can be configured to meet regulatory compliance. It scores ✅ ✅. Every Zone and Hub in cosmos has their own validator set / token but research is underway to have the hub validate the state transition of connected zones, but as this is still early in the research phase scores ✅ for now.

Current Adoption

Cosmos

The Cosmos project started in 2016 with an ICO held in April 2017. There are currently around 50 projects building on the Cosmos SDK with a full list can be seen here and filtering for Cosmos SDK . Not all of the projects will necessarily connect using native cosmos sdk and IBC and some have forked parts of the Cosmos SDK and utilise the tendermint consensus such as Binance Chain but have said they will connect in the future.

Polkadot

The Polkadot project started in 2016 with an ICO held in October 2017. There are currently around 70 projects building on Substrate and a full list can be seen here and filtering for Substrate Based. Like with Cosmos not all projects built using substrate will necessarily connect to Polkadot and parachains or parathreads aren’t currently implemented in either the Live or Test network (Kusama) as of the time of this writing.

Avalanche

Avalanche in comparison started much later with Ava Labs being founded in 2018. Avalanche held it’s ICO in July 2020. Due to lot shorter time it has been in development, the number of projects confirmed are smaller with around 14 projects currently building on Avalanche. Due to the customisability of the platform though, many virtual machines can be used within a subnet making the process incredibly easy to port projects over. As an example, it will launch with the Ethereum Virtual Machine which enables byte for byte compatibility and all the tooling like Metamask, Truffle etc. will work, so projects can easily move over to benefit from the performance, decentralisation and low gas fees offered. In the future Cosmos and Substrate virtual machines could be implemented on Avalanche.

Results

Whilst it’s still early for all 3 projects (and the entire blockchain space as a whole), there is currently more projects confirmed to be building on Cosmos and Polkadot, mostly due to their longer time in development. Whilst Cosmos has fewer projects, zones are implemented compared to Polkadot which doesn’t currently have parachains. IBC to connect zones and hubs together is due to launch Q2 2021, thus both score ✅✅✅. Avalanche has been in development for a lot shorter time period, but is launching with an impressive feature set right from the start with ability to create subnets, VMs, assets, NFTs, permissioned and permissionless blockchains, cross chain atomic swaps within a subnet, smart contracts, bridge to Ethereum etc. Applications can easily port over from other platforms and use all the existing tooling such as Metamask / Truffle etc but benefit from the performance, decentralisation and low gas fees offered. Currently though just based on the number of projects in comparison it scores ✅.

Enterprise Adoption

Cosmos

Cosmos enables permissioned and permissionless zones which can connect to each other with the ability to have full control over who validates the blockchain. For permissionless zones each zone / hub can have their own token and they are in control who validates.

Polkadot

With polkadot the state transition is performed by a small randomly selected assigned group of validators from the relay chain plus with the possibility that state is rolled back if an invalid transaction of any of the other parachains is found. This may pose a problem for enterprises that need complete control over who performs validation for regulatory reasons. In addition due to the limited number of parachain slots available Enterprises would have to acquire and lock up large amounts of a highly volatile asset (DOT) and have the possibility that they are outbid in future auctions and find they no longer can have their parachain validated and parathreads don’t provide the guaranteed performance requirements for the application to function.

Avalanche

Avalanche enables permissioned and permissionless subnets and complex rulesets can be configured to meet regulatory compliance. For example a subnet can be created where its mandatory that all validators are from a certain legal jurisdiction, or they hold a specific license and regulated by the SEC etc. Subnets are also able to scale to tens of thousands of validators, and even potentially millions of nodes, all participating in consensus so every enterprise can run their own node rather than only a small amount. Enterprises don’t have to hold large amounts of a highly volatile asset, but instead pay a fee in AVAX for the creation of the subnets and blockchains which is burnt.

Results

Avalanche provides the customisability to run private permissioned blockchains as well as permissionless where the enterprise is in control over who validates the blockchain, with the ability to use complex rulesets to meet regulatory compliance, thus scores ✅✅✅. Cosmos is also able to run permissioned and permissionless zones / hubs so enterprises have full control over who validates a blockchain and scores ✅✅. Polkadot requires locking up large amounts of a highly volatile asset with the possibility of being outbid by competitors and being unable to run the application if the guaranteed performance is required and having to migrate away. The relay chain validates the state transition and can roll back the parachain should an invalid block be detected on another parachain, thus scores ✅.
https://preview.redd.it/li5jy6u6wpq51.png?width=1000&format=png&auto=webp&s=e2a95f1f88e5efbcf9e23c789ae0f002c8eb73fc

Interoperability

Cosmos

Cosmos will connect Hubs and Zones together through its IBC protocol (due to release in Q1 2020). Connecting to blockchains outside of the Cosmos ecosystem would either require the connected blockchain to fork their code to implement IBC or more likely a custom “Peg Zone” will be created specific to work with a particular blockchain it’s trying to bridge to such as Ethereum etc. Each Zone and Hub has different trust levels and connectivity between 2 zones can have different trust depending on which path it takes (this is discussed more in this article). Finality time is low at 6 seconds, but depending on the number of hops, this can increase significantly.

Polkadot

Polkadot’s shared state means each parachain that connects shares the same trust assumptions, of the relay chain validators and that if one blockchain needs to be reverted, all of them will need to be reverted. Interoperability is enabled between parachains through Cross-Chain Message Passing (XCMP) protocol and is also possible to connect to other systems through bridges, which are specifically designed parachains or parathreads that each are custom made to interact with another ecosystem such as Ethereum and Bitcoin. Finality time between parachains is around 60 seconds, but longer will be needed (initial figures of 60 minutes in the whitepaper) for connecting to external blockchains. Thus limiting the appeal of connecting two external ecosystems together through Polkadot. Polkadot is also limited in the number of Parachain slots available, thus limiting the amount of blockchains that can be bridged. Parathreads could be used for lower performance bridges, but the speed of future blockchains is only going to increase.

Avalanche

A subnet can validate multiple virtual machines / blockchains and all blockchains within a subnet share the same trust assumptions / validator set, enabling cross chain interoperability. Interoperability is also possible between any other subnet, with the hope Avalanche will consist of thousands of subnets. Each subnet may have a different trust level, but as the primary network consists of all validators then this can be used as a source of trust if required. As Avalanche supports many virtual machines, bridges to other ecosystems are created by running the connected virtual machine. There will be an Ethereum bridge using the EVM shortly after mainnet. Finality time is much faster at sub 3 seconds (with most happening under 1 second) with no chance of rolling back so more appealing when connecting to external blockchains.

Results

All 3 systems are able to perform interoperability within their ecosystem and transfer assets as well as data, as well as use bridges to connect to external blockchains. Cosmos has different trust levels between its zones and hubs and can create issues depending on which path it takes and additional latency added. Polkadot provides the same trust assumptions for all connected parachains but has long finality and limited number of parachain slots available. Avalanche provides the same trust assumptions for all blockchains within a subnet, and different trust levels between subnets. However due to the primary network consisting of all validators it can be used for trust. Avalanche also has a much faster finality time with no limitation on the number of blockchains / subnets / bridges that can be created. Overall all three blockchains excel with interoperability within their ecosystem and each score ✅✅.

Tokenomics

Cosmos

The ATOM token is the native token for the Cosmos Hub. It is commonly mistaken by people that think it’s the token used throughout the cosmos ecosystem, whereas it’s just used for one of many hubs in Cosmos, each with their own token. Currently ATOM has little utility as IBC isn’t released and has no connections to other zones / hubs. Once IBC is released zones may prefer to connect to a different hub instead and so ATOM is not used. ATOM isn’t a fixed capped supply token and supply will continuously increase with a yearly inflation of around 10% depending on the % staked. The current market cap for ATOM as of the time of this writing is $1 Billion with 203 million circulating supply. Rewards can be earnt through staking to offset the dilution caused by inflation. Delegators can also get slashed and lose a portion of their ATOM should the validator misbehave.

Polkadot

Polkadot’s native token is DOT and it’s used to secure the Relay Chain. Each parachain needs to acquire sufficient DOT to win an auction on an available parachain lease period of up to 24 months at a time. Parathreads have a fixed fee for registration that would realistically be much lower than the cost of acquiring a parachain slot and compete with other parathreads in a per-block auction to have their transactions included in the next relay chain block. DOT isn’t a fixed capped supply token and supply will continuously increase with a yearly inflation of around 10% depending on the % staked. The current market cap for DOT as of the time of this writing is $4.4 Billion with 852 million circulating supply. Delegators can also get slashed and lose their DOT (potentially 100% of their DOT for serious attacks) should the validator misbehave.

Avalanche

AVAX is the native token for the primary network in Avalanche. Every validator of any subnet also has to validate the primary network and stake a minimum of 2000 AVAX. There is no limit to the number of validators like other consensus methods then this can cater for tens of thousands even potentially millions of validators. As every validator validates the primary network, this can be a source of trust for interoperability between subnets as well as connecting to other ecosystems, thus increasing amount of transaction fees of AVAX. There is no slashing in Avalanche, so there is no risk to lose your AVAX when selecting a validator, instead rewards earnt for staking can be slashed should the validator misbehave. Because Avalanche doesn’t have direct slashing, it is technically possible for someone to both stake AND deliver tokens for something like a flash loan, under the invariant that all tokens that are staked are returned, thus being able to make profit with staked tokens outside of staking itself.
There will also be a separate subnet for Athereum which is a ‘spoon,’ or friendly fork, of Ethereum, which benefits from the Avalanche consensus protocol and applications in the Ethereum ecosystem. It’s native token ATH will be airdropped to ETH holders as well as potentially AVAX holders as well. This can be done for other blockchains as well.
Transaction fees on the primary network for all 3 of the blockchains as well as subscription fees for creating a subnet and blockchain are paid in AVAX and are burnt, creating deflationary pressure. AVAX is a fixed capped supply of 720 million tokens, creating scarcity rather than an unlimited supply which continuously increase of tokens at a compounded rate each year like others. Initially there will be 360 tokens minted at Mainnet with vesting periods between 1 and 10 years, with tokens gradually unlocking each quarter. The Circulating supply is 24.5 million AVAX with tokens gradually released each quater. The current market cap of AVAX is around $100 million.

Results

Avalanche’s AVAX with its fixed capped supply, deflationary pressure, very strong utility, potential to receive air drops and low market cap, means it scores ✅✅✅. Polkadot’s DOT also has very strong utility with the need for auctions to acquire parachain slots, but has no deflationary mechanisms, no fixed capped supply and already valued at $3.8 billion, therefore scores ✅✅. Cosmos’s ATOM token is only for the Cosmos Hub, of which there will be many hubs in the ecosystem and has very little utility currently. (this may improve once IBC is released and if Cosmos hub actually becomes the hub that people want to connect to and not something like Binance instead. There is no fixed capped supply and currently valued at $1.1 Billion, so scores ✅.

All three are excellent projects and have similarities as well as many differences. Just to reiterate this article is not intended to be an extensive in-depth list, but rather an overview based on some of the criteria that I feel are most important. For a more in-depth view I recommend reading the articles for each of the projects linked above and coming to your own conclusions, you may have different criteria which is important to you, and score them differently. There won’t be one platform to rule them all however, with some uses cases better suited to one platform over another, and it’s not a zero-sum game. Blockchain is going to completely revolutionize industries and the Internet itself. The more projects researching and delivering breakthrough technology the better, each learning from each other and pushing each other to reach that goal earlier. The current market is a tiny speck of what’s in store in terms of value and adoption and it’s going to be exciting to watch it unfold.

ABSTRACT

The effects of the web by a number of companies have seduced a large number of users as these companies keep their data to prevent them from searching for alternatives. Likewise, these huge platforms have attracted applications to build their highest ecosystems before either severing access or actively opposing their interests when the applications became so successful. As a result, these walled gardens have effectively hindered innovation and monopolized large sections of the web. After the emergence of blockchain technology and decentralized cryptocurrencies, the need for applications to support decentralization has emerged. Several blockchain-based companies, applications and platforms have appeared in decentralization. In this research report, we will explain the approach adopted by the NEAR decentralization platform in designing and implementing the basic technology for its system. Near is a basic platform for cloud computing and decentralized storage managed by the community, designed to enable the open web for the future. On this web, everything can be created from new currencies to new applications to new industries, opening the door to an entirely new future.

1. INTRODUCTION

The richness of the web is increasing day by day with the combined efforts of millions of people who have benefited from “innovation without permission” as content and applications are created without asking anyone. this lack of freedom of data has led to an environment hostile to the interests of its participants. And as we explained in the summary previously, web hosting companies have hindered innovation and greatly monopolized the web.
In the future, we can fix this by using new technologies to re-enable the permissionless innovation of the past in a way, which creates a more open web where users are free and applications are supportive rather than adversarial to their interests.
Decentralization emerged after the global financial crisis in 2008, which created fundamental problems of confidence in the heavily indebted banking system. Then the decentralized financial sector based on Blockchain technology has emerged since 2009.
Decentralized Blockchain technology has made it easy for decentralized digital currencies like Bitcoin to exchange billions of dollars in peer-to-peer transfers for a fraction of the price of a traditional banking system. This technology allows participants in the over $ 50 billion virtual goods economy to track, own and trade in these commodities without permission. It allows real-world goods to cross into the digital domain, with verified ownership and tracking just like that of the digital.
By default, the Internet where freedom of data enables innovation will lead to the development of a new form of software development. On this web, developers can quickly create applications from open state components and boost their efforts by using new business models that are enabled from within the program itself rather than relying on parasitic relationships with their users. This not only accelerates the creation of applications that have a more honest and cooperative relationship with its users, but also allows the emergence of completely new business built on them.
To enable these new applications and the open web, it needs the appropriate infrastructure. The new web platform cannot be controlled by a single entity and its use is not limited due to insufficient scalability. It should be decentralized in design like the web itself and supported by a community of distributors widely so that the value they store cannot be monitored, modified or removed without permission from the users who store this value on their behalf.
A new decentralization technology (Blockchain), which has facilitated decentralized digital currencies like Bitcoin, has made billions of dollars in peer-to-peer transfers at a fraction of the price of the traditional banking system. This technology allows participants in the $ 50 billion + virtual goods economy to track, own and trade in these goods without permission. It allows real-world goods to cross into the digital domain, with verified ownership and tracking just like that of the digital.
Although the cost of storing data or performing a calculation on the Ethereum blockchain is thousands and millions of times higher than the cost of performing the same functionality on Amazon Web Services. A developer can always create a “central” app or even a central currency for a fraction of the cost of doing the same on a decentralized platform because a decentralized platform, by definition, will have many iterations in its operations and storage.
Bitcoin can be thought of as the first, very basic, version of this global community-run cloud, though it is primarily used only to store and move the Bitcoin digital currency.
Ethereum is the second and slightly more sophisticated version, which expanded the basic principles of Bitcoin to create a more general computing and storage platform, though it is a raw technology, which hasn’t achieved meaningful mainstream adoption.

1.1 WHY IS IT IMPORTANT TO PAY THE EXTRA COST TO SUPPORT DECENTRALIZATION?

Because some elements of value, for example bits representing digital currency ownership, personal identity, or asset notes, are very sensitive. While in the central system, the following players can change the value of any credits they come into direct contact with:
  1. The developer who controls the release or update of the application’s code
  2. The platform where the data is stored
  3. The servers which run the application’s code
Even if none of these players intend to operate with bad faith, the actions of governments, police forces and hackers can easily turn their hands against their users and censor, modify or steal the balances they are supposed to protect.
A typical user will trust a typical centralized application, despite its potential vulnerabilities, with everyday data and computation. Typically, only banks and governments are trusted sufficiently to maintain custody of the most sensitive information — balances of wealth and identity. But these entities are also subject to the very human forces of hubris, corruption and theft.
Especially after the 2008 global financial crisis, which demonstrated the fundamental problems of confidence in a highly indebted banking system. And governments around the
world apply significant capital controls to citizens during times of crisis. After these examples, it has become a truism that hackers now own most or all of your sensitive data.
These decentralized applications operate on a more complex infrastructure than today’s web but they have access to an instantaneous and global pool of currency, value and information that today’s web, where data is stored in the silos of individual corporations, cannot provide.

1.2 THE CHALLENGES OF CREATING A DECENTRALIZED CLOUD

A community-run system like this has very different challenges from centralized “cloud” infrastructure, which is running by a single entity or group of known entities. For example:
  1. It must be both inclusive to anyone and secure from manipulation or capture.
  2. Participants must be fairly compensated for their work while avoiding creating incentives for negligent or malicious behavior.
  3. It must be both game theoretically secure so good actors find the right equilibrium and resistant to manipulation so bad actors are actively prevented from negatively affecting the system.

2. NEAR

NEAR is a global community-run computing and storage cloud which is organized to be permissionless and which is economically incentivized to create a strong and decentralized data layer for the new web.
Essentially, it is a platform for running applications which have access to a shared — and secure — pool of money, identity and data which is owned by their users. More technically, it combines the features of partition-resistant networking, serverless compute and distributed storage into a new kind of platform.
NEAR is a community-managed, decentralized cloud storage and computing platform, designed to enable the open web in the future. It uses the same core technology for Bitcoin and Blockchain. On this web, everything can be created from new currencies to new applications to new industries, opening the door to an entirely new future.
NEAR is a decentralized community-run cloud computing and storage platform, which is designed to enable the open web of the future. On this web, everything from new currencies to new applications to new industries can be created, opening the door to a brand new future.
NEAR is a scalable computing and storage platform with the potential to change how systems are designed, how applications are built and how the web itself works.
It is a complex technology allow developers and entrepreneurs to easily and sustainably build applications which reap the benefits of decentralization and participate in the Open Web while minimizing the associated costs for end users.
NEAR creates the only community-managed cloud that is strong enough to power the future of the open web, as NEAR is designed from the ground up to deliver intuitive experiences to
end users, expand capacity across millions of devices, and provide developers with new and sustainable business models for their applications.
The NEAR Platform uses a token — also called “NEAR”. This token allows the users of these cloud resources, regardless of where they are in the world, to fairly compensate the providers of the services and to ensure that these participants operate in good faith.

2.1 WHY NEAR?

Through focus, we find that Platforms based on blockchain technologies like Bitcoin and Ethereum have made great progress and enriched the world with thousands of innovative applications spanning from games to decentralized financing.
However, these original networks and none of the networks that followed were not able to bridge the gap towards mainstream adoption of the applications created above them and do not provide this type of standard that fully supports the web.
This is a result of two key factors:
  1. System design
  2. Organization design
System design is relevant because the technical architecture of other platforms creates substantial problems with both usability and scalability which have made adoption nearly impossible by any but the most technical innovators. End-users experience 97–99% dropoff rates when using applications and developers find the process of creating and maintaining their applications endlessly frustrating.
Fixing these problems requires substantial and complex changes to current protocol architectures, something which existing organizations haven’t proven capable of implementing. Instead, they create multi-year backlogs of specification design and implementation, which result in their technology falling further and further behind.
NEAR’s platform and organization are architected specifically to solve the above-mentioned problems. The technical design is fanatically focused on creating the world’s most usable and scalable decentralized platform so global-scale applications can achieve real adoption. The organization and governance structure are designed to rapidly ship and continuously evolve the protocol so it will never become obsolete.

2.1.1 Features, which address these problems:

1. USABILITY FIRST
The most important problem that needs to be addressed is how to allow developers to create useful applications that users can use easily and that will capture the sustainable value of these developers.
2. End-User Usability
Developers will only build applications, which their end users can actually use. NEAR’s “progressive security” model allows developers to create experiences for their users which more closely resemble familiar web experiences by delaying onboarding, removing the need for user to learn “blockchain” concepts and limiting the number of permission-asking interactions the user must have to use the application.
1. Simple Onboarding: NEAR allows developers to take actions on behalf of their users, which allows them to onboard users without requiring these users to provide a wallet or interact with tokens immediately upon reaching an application. Because accounts keep track of application-specific keys, user accounts can also be used for the kind of “Single Sign On” (SSO) functionality that users are familiar with from the traditional web (eg “Login with Facebook/Google/Github/etc”).
2. Easy Subscriptions: Contract-based accounts allow for easy creation of subscriptions and custom permissioning for particular applications.
3. Familiar Usage Styles: The NEAR economic model allows developers to pay for usage on behalf of their users in order to hide the costs of infrastructure in a way that is in line with familiar web usage paradigms.
4. Predictable Pricing: NEAR prices transactions on the platform in simple terms, which allow end-users to experience predictable pricing and less cognitive load when using the platform.

2.1.2 Design principles and development NEAR’s platform

1. Usability: Applications deployed to the platform should be seamless to use for end users and seamless to create for developers. Wherever possible, the underlying technology itself should fade to the background or be hidden completely from end users. Wherever possible, developers should use familiar languages and patterns during the development process. Basic applications should be intuitive and simple to create while applications that are more robust should still be secure.
2. Scalability: The platform should scale with no upper limit as long as there is economic justification for doing so in order to support enterprise-grade, globally used applications.
3. Sustainable Decentralization: The platform should encourage significant decentralization in both the short term and the long term in order to properly secure the value it hosts. The platform — and community — should be widely and permissionlessly inclusive and actively encourage decentralization and participation. To maintain sustainability, both technological and community governance mechanisms should allow for practical iteration while avoiding capture by any single parties in the end.
4. Simplicity: The design of each of the system’s components should be as simple as possible in order to achieve their primary purpose. Optimize for simplicity, pragmatism and ease of understanding above theoretical perfection.

2.2 HOW NEAR WORKS?

NEAR’s platform provides a community-operated cloud infrastructure for deploying and running decentralized applications. It combines the features of a decentralized database with others of a serverless compute platform. The token, which allows this platform to run also, enables applications built on top of it to interact with each other in new ways. Together, these features allow developers to create censorship resistant back-ends for applications that deal with high stakes data like money, identity, assets, and open-state components, which interact seamlessly with each other. These application back-ends and components are called “smart contracts,” though we will often refer to these all as simply “applications” here.
The infrastructure, which makes up this cloud, is created from a potentially infinite number of “nodes” run by individuals around the world who offer portions of their CPU and hard drive space — whether on their laptops or more professionally deployed servers. Developers write smart contracts and deploy them to this cloud as if they were deploying to a single server, which is a process that feels very similar to how applications are deployed to existing centralized clouds.
Once the developer has deployed an application, called a “smart contract”, and marked it unchangeable (“immutable”), the application will now run for as long as at least a handful of members of the NEAR community continue to exist. When end users interact with that deployed application, they will generally do so through a familiar web or mobile interface just like any one of a million apps today.
In the central cloud hosted by some companies today like: Amazon or Google, developers pay for their apps every month based on the amount of usage needed, for example based on the number of requests created by users visiting their webpages. The NEAR platform similarly requires that either users or developers provide compensation for their usage to the community operators of this infrastructure. Like today’s cloud infrastructure, NEAR prices usage based on easy to understand metrics that aren’t heavily influenced by factors like system congestion. Such factors make it very complicated for developers on alternative blockchain-based systems today.
In the centralized cloud, the controlling corporation makes decisions unilaterally. NEAR community-run cloud is decentralized so updates must ultimately be accepted by a sufficient quorum of the network participants. Updates about its future are generated from the community and subject to an inclusive governance process, which balances efficiency and security.
In order to ensure that the operators of nodes — who are anonymous and potentially even malicious — run the code with good behavior, they participate in a staking process called “Proof of Stake”. In this process, they willingly put a portion of value at risk as a sort of deposit, which they will forfeit if it is proven that they have operated improperly.

2.2.1 Elements of the NEAR’s Platform

The NEAR platform is made up of many separate elements. Some of these are native to the platform itself while others are used in conjunction with or on top of it.
1. THE NEAR TOKEN
NEAR token is the fundamental native asset of the NEAR ecosystem and its functionality is enabled for all accounts. Each token is a unique digital asset similar to Ether, which can be used to:
a) Pay the system for processing transactions and storing data.
b) Run a validating node as part of the network by participating in the staking process.
c) Help determine how network resources are allocated and where its future technical direction will go by participating in governance processes.
The NEAR token enables the economic coordination of all participants who operate the network plus it enables new behaviors among the applications which are built on top of that network.
2. OTHER DIGITAL ASSETS
The platform is designed to easily store unique digital assets, which may include, but aren’t limited to:
  • Other Tokens: Tokens bridged from other chains (“wrapped”) or created atop the NEAR Platform can be easily stored and moved using the underlying platform. This allows many kinds of tokens to be used atop the platform to pay for goods and services. “Stablecoins,” specific kinds of token which are designed to match the price of another asset (like the US Dollar), are particularly useful for transacting on the network in this way.
  • Unique Digital Assets: Similar to tokens, digital assets (sometimes called “Non Fungible Tokens” (NFTs) ranging from in-game collectibles to representations of real-world asset ownership can be stored and moved using the platform.
3. THE NEAR PLATFORM
The core platform, which is made up of the cloud of community-operated nodes, is the most basic piece of infrastructure provided. Developers can permissionlessly deploy smart contracts to this cloud and users can permissionlessly use the applications they power. Applications, which could range from consumer-facing games to digital currencies, can store their state (data) securely on the platform. This is conceptually similar to the Ethereum platform.
Operations that require an account, network use, or storage at the top of the platform require payment to the platform in the form of transaction fees that the platform then distributes to its community from the authentication contract. These operations could include creating new accounts, publishing new contracts, implementing code by contract and storing or modifying data by contract.
As long as the rules of the protocol are followed, any independent developer can write software, which interfaces with it (for example, by submitting transactions, creating accounts or even running a new node client) without asking for anyone’s permission first.
4. THE NEAR DEVELOPMENT SUITE
Set of tools and reference implementations created to facilitate its use by those developers and end users who prefer them. These tools include:
  • NEAR SDKs: NEAR platform supports (Rust and AssemblyScript) languages to write smart contracts. To provide a great experience for developers, NEAR has a full SDK, which includes standard data structures, examples and testing tools for these two languages.
  • Gitpod for NEAR: NEAR uses existing technology Gitpod to create zero time onboarding experience for developers. Gitpod provides an online “Integrated Development Environment” (IDE), which NEAR customized to allow developers to easily write, test and deploy smart contracts from a web browser.
  • NEAR Wallet: A wallet is a basic place for developers and end users to store the assets they need to use the network. NEAR Wallet is a reference implementation that is intended to work seamlessly with the progressive security model that lets application developers design more effective user experiences. It will eventually include built-in functionality to easily enable participation by holders in staking and governance processes on the network.
  • NEAR Explorer: To aid with both debugging of contracts and the understanding of network performance, Explorer presents information from the blockchain in an easily digestible web-based format.
  • NEAR Command Line Tools: The NEAR team provides a set of straightforward command line tools to allow developers to easily create, test and deploy applications from their local environments.
All of these tools are being created in an open-source manner so they can be modified or deployed by anyone.

3. ECONOMIC

Primarily economic forces drive the ecosystem, which makes up the NEAR platform. This economy creates the incentives, which allow participants permissionlessly organize to drive the platform’s key functions while creating strong disincentives for undesirable, irresponsible or malicious behavior. In order for the platform to be effective, these incentives need to exist both in the short term and in the long term.
The NEAR platform is a market among participants interested in two aspects:
  • On the supply side, certification contract operators and other core infrastructure must be motivated to provide these services that make up the community cloud.
  • On the demand side, platform developers and end-users who pay for their use need to be able to do so in a simple, clear and consistent way that helps them.
Further, economic forces can also be applied to support the ecosystem as a whole. They can be used at a micro level to create new business models by directly compensating the developers who create its most useful applications. They can also be used at a macro level by coordinating the efforts of a broader set of ecosystem participants who participate in everything from education to governance.

3.1 NEAR ECONOMY DESIGN PRINCIPLES

NEAR’s overall system design principles are used to inform its economic design according to the following interpretations:
1. Usability: End users and developers should have predictable and consistent pricing for their usage of the network. Users should never lose data forever.
2. Scalability: The platform should scale at economically justified thresholds.
3. Simplicity: The design of each of the system’s components should be as simple as possible in order to achieve their primary purpose.
4. Sustainable Decentralization: The barrier for participation in the platform as a validating node should be set as low as possible in order to bring a wide range of participants. Over time, their participation should not drive wealth and control into the hands of a small number. Individual transactions made far in the future must be at least as secure as those made today in order to safeguard the value they modify.

3.2 ECONOMIC OVERVIEW

The NEAR economy is optimized to provide developers and end users with the easiest possible experience while still providing proper incentives for network security and ecosystem development.
Summary of the key ideas that drive the system:
  • Thresholded Proof of Stake: Validating node operators provide scarce and valuable compute resources to the network. In order to ensure that the computations they run are correct, they are required to “stake” NEAR tokens, which guarantee their results. If these results are found to be inaccurate, the staker loses their tokens. This is a fundamental mechanism for securing the network. The threshold for participating in the system is set algorithmically at the lowest level possible to allow for the broadest possible participation of validating nodes in a given “epoch” period (½ of a day).
  • Epoch Rewards: Node operators are paid for their service a fixed percentage of total supply as a “security” fee of roughly 4.5% annualized. This rate targets sufficient participation levels among stakers in order to secure the network while balancing with other usage of NEAR token in the ecosystem.
  • Protocol treasury: In addition to validators, protocol treasury received a 0.5% of total supply annually to continuously re-invest into ecosystem development.
  • Transaction Costs: Usage of the network consumes two separate kinds of resources — instantaneous and long term. Instantaneous costs are generated by every transaction because each transaction requires the usage of both the network itself and some of its computation resources. These are priced together as a mostly-predictable cost per transaction, which is paid in NEAR tokens.
  • Storage Costs: Storage is a long term cost because storing data represents an ongoing burden to the nodes of the network. Storage costs are covered by maintaining minimum balance of NEAR tokens on the account or contract. This provides indirect mechanism of payment via inflation to validators for maintaining contract and account state on their nodes.
  • Inflation: Inflation is determined as combination of payouts to validators and protocol treasury minus the collected transaction fees and few other NEAR burning mechanics (like name auction). Overall the maximum inflation is 5%, which can go down over time as network gets more usage and more transactions fees are burned. It’s possible that inflation becomes negative (total supply decreases) if there is enough fees burned.
  • Scaling Thresholds: In a network, which scales its capacity relative to the amount of usage it receives, the thresholds, which drive the network to bring on additional capacity are economic in nature.
  • Security Thresholds: Some thresholds, which provide for good behavior among participants are set using economic incentives. For example, “Fishermen” (described separately).

Why i’m bullish on Zilliqa (long read)

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

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

For DeFi to grow we need a solution for network congestion, fast

We keep hearing more and more about cases of decentralized projects that are not fundamentally decentralized. We also have an issue where blockchain networks lack any serious interoperability, resulting in almost 0 retail adoptions. If I were to start talking about Ethereum, network congestion, and bottlenecks I might as well go on a long tirade. But what I want to do instead is showcase a possible solution, Fusion.
As you may all know, Bitcoin and Ethereum are heading for old highs since stocks and futures opened green this week. If we are lucky we might get to August price levels at $12k. However, that’s not the only thing that we may get from last month. As you all remember, yield farming is all the craze in this bull run and the heightened activity contributed to a severe bottleneck on Ethereum. We saw how that looked like recently when Uniswap did their $1200 UNI airdrop.
Almost everyone did at least one transaction that day and people had to wait for hours for confirmation. I don’t even have to mention the worst thing, $30 in gas fees for a single transaction. People who don’t have a large portfolio are being ‘scammed’ in fees for making a simple token swap. It’s even worse if you are a small fish and wish to start yield farming. You almost lose more money than you make if you decide to farm.
Fusion fixes this by introducing a fully decentralized cross-chain solution that provides an environment with accessible products and services to the masses. Apart from having special APIs that allow developers to build dApps on the Fusion Network that can communicate with every other network, the protocol also has a great fix for scalability issues. The team introduced a ‘Ticketed Proof of Stake (TPoS) consensus mechanism that secures transactions. Average transaction time needs around 15 seconds for confirmation, supporting 2500 to 3000 TPS.
They also have a custody solution that completely changes decentralization. Their Distributed Control Rights Management (DCRM) technology distributes private key storage to multiple nodes through sharding. In most projects, you’ll see that the devs implemented a centralized server for custody purposes. That kind of model is practically useless as hackers have an easy point of attack.
DCRM is so powerful that many leading cryptologists in the world have approved it. Including experts such as CompSci professor at CUNY Rosario Gennaro, CompSci professor at the University of Versailles Louis Goubin, CryptoExperts CEO Pascal Paillier, and researcher from the department of CompSci at Cornell University Steven Goldfeder.
Fusion already proved its useability to the world with its Anyswap DEX. Anyswap is based on the Fusion network which in return provides farmers with the lowest fees in DeFi. Imagine paying $0.0001 per transaction for a simple token swap on a DEX instead of having to pay up to $40 on Uniswap. The protocol even has a native governance model with the ANY token through which users can bring changes through a voting process. Anyswap is practically what Uniswap would look like if it had a layer 2 scalability solution.
In the end, remember to do your OWN research. But I also have to impose that there is definitely something worthwhile with both Fusion and Anyswap as they offer everything that developers are currently struggling to deliver.

Good Opportunity for NEO to take some of Ethereum's marketshare?

Long time lurker, and have never posted before.
Ethereum has taken the spotlight lately but with that has come increased analysis and criticism of the platform. There are a couple things happening to Ethereum lately that make me think it's the perfect time for NEO to step up and show it's value (which I am sure Da & team already know).
Bitcoin Vs Ethereum with Samson Mow & Vitalik Buterin
Though I don't think this was the best podcast, it does highlight some major issues with ETH. The rollback, centralized-ish, supply-gate, no clear focus, and Vitalik and Ethereum foundation not realizing how difficult implementing ETH2 would be. Vitalik stating somewhere in the middle "We are at least 2 more years away."

Prysm time bug behind ETH 2.0 Medalla testnet crash
Everyone was excited for this release but I didn't realize it was just the testnet release. It seems to me like Ethereum has a long ways to go to improve their scalability.

All that being said, I do think Neo definitely has its own hurdles to overcome but I am more optimistic than ever. As a community, I think it is important for us now more than ever to be vocal and support Neo in any way that we can. Hence me writing my first post ever.
Have a great week everyone!
