## What Is Revain (REV)? 

Revain is an online platform for Ethereum [blockchain](https://coinmarketcap.com/headlines/news/what-is-ethereum-2-0-why-is-it-important/)-based tokens reviews, designed to allow developers to receive constructive feedback about their projects. The protocol also incentivizes authors to provide high-quality reviews. 

Revain was the first platform to combine the features of traditional review sites and blockchain technology. Revain’s ultimate goal is to create a legitimate and genuine feedback structure for all global products and services that utilize emerging technologies, such as machine learning and blockchain.

Revain implements artificial intelligence tools and a manual review system to ensure the high quality of reviews. The core features of the protocol include:

Legitimate reviews: Revain uses only original content from a diverse range of experts on its website. 

Stable system: the protocol runs on two different tokens, the REV and the RVN, allowing for smooth functioning of the system. The RVN token helps facilitate interactions between users on the platform. 

Immutable information: The system does not allow both regular users and Revain itself to edit the information of other users.


### Who Are the Founders of Revain? 

Revain was established in 2018 by a group of technology experts from Moscow, Russia.

The platform was founded by Rinat Arslanov, who is also its current CEO. Arslanov is a venture capitalist and an entrepreneur with more than ten years of experience in the blockchain industry.

Other notable team members include the CFO Grigor Aproyan, the COO Aleksey Belashenko; the CTO Andrew Timokhin, the product owner Dmitry Bogachev, the designer Vlad Bocharov, the digital manager Ksenia Fendich, and the account manager Tatiana Muntyanu.


#### What Makes Revain Unique? 

Since its inception in 2018, the platform claims to have achieved the largest number of user reviews in the industry. Revain’s protocol consists of seven major blockchain divisions: projects, casinos, exchanges, mining pools, wallets, cards, and games.

What differentiates the platform from other blockchain-based projects is that it utilizes two tokens to increase its efficiency. Another major component of Revain is its integration with the IBM Watson Tone Analyzer. 

Revain also allows companies to determine specific criteria for evaluating the quality of user-provided reviews. For instance, a company might require their reviewers to attach proof, increasing the credibility of reviews. Reviewers who fail to do so will then stand the risk of having their reviews rejected by the protocol. 


#### How Many Revain Tokens (REV) Are There in Circulation? 

Initially, the platform started out with the R and RVN tokens. However, on March 26, 2020, the company swapped R for REV tokens due to the difficulty of integrating the former into other blockchains. The tokens currently used on the platform are the REV and RVN.

RVN token is a stablecoin and is exclusive to the platform, as it has not been released into open circulation. The REV token, on the other hand, is fully tradable. Registered companies on the platform can use the REV token to incentivize authors to write reviews.

The REV token is based on Ethereum’s [ERC-20](https://coinmarketcap.com/alexandria/article/what-are-erc-20-tokens-find-out-now-as-the-decentralized-finance-industry-takes-off) standard, TRC20 and BEP20. REV is a utility token and is used for rewarding authors. As of February 2021, there are 85,061,485,690 REV in circulation.

Holo is a peer-to-peer distributed platform for hosting decentralized applications built using Holochain, a framework for developing DApps that does not require the use of blockchain technology. The goal of Holo is to serve as a bridge between the broader internet and apps built using Holochain, offering an ecosystem and marketplace in which DApps are easily accessible, as they are hosted on the internet by Holo network participants.

The Holo network will be facilitated using a token called HoloFuel, which is actively being tested and will act as an accounting system to pay hosts for their services. In 2018, the project minted an ERC-20 token, HOT — also known as HoloToken — as an "IOU" that will be redeemable for HoloFuel upon launch.

Holo is still in development and is expected to launch for open alpha and beta testing by 2021.

Siacoin (SC) is the native utility token of Sia, a blockchain-based distributed, decentralized cloud storage platform. Sia acts as a secure, trustless marketplace for cloud storage in which users can lease access to their unused storage space. Agreements and transactions are enforced with smart contracts, and Siacoin is the medium of exchange for paying for storage on the network. The main goal of the project is to become the "backbone storage layer of the internet."

Sia was originally announced in May 2014 before being revised and re-announced a year later in May 2015. It officially launched in June 2015.

NEM is a blockchain platform that was launched in March of 2015. It was one of the pioneers of the cryptocurrency industry, and sought to improve on the imperfections found on other chains at the time. It was one of the first non-turing complete chains to feature user-defined tokens (called mosaics), namespaces, multisignature accounts, and a P2P reputation system based on EigenTrust++. Its most notable contribution to the space is the proof-of-importance consensus mechanism, which sought to reward on-chain activity and deter the concentration of wealth commonly associated with proof-of-stake. Its client, NIS, is written in Java.

NEM has a global community. It sees the most utility as an alternative form of payment for businesses and vendors, and has a variety of social media apps built on top of it in Japan, such as nemgraph, a community-driven owned and operated alternative to Instagram.

In December 2021, NEM was hard forked by a pseudonymous team of cryptocurrency experts and enthusiasts alike. Titled Harlock, this hard fork signaled the community’s intent to take NEM from a shadow of its former self into the world’s leading payments platform for on-chain and off-chain media content.

DigiByte (DGB) is an open source blockchain and asset creation platform. Development began in October 2013 and the genesis block of its DGB token was mined in January 2014 as a fork of Bitcoin (BTC).

A longstanding public blockchain and cryptocurrency, DigiByte uses five different algorithms to improve security, and originally aimed to improve on the Bitcoin blockchain’s security, capacity and transaction speed.

DigiByte consists of three layers: a smart contract “App Store,” a public ledger and the core protocol featuring nodes communicating to relay transactions.

Amp is an open-source, decentralized protocol that provides collateral as a service. Amp is described as the new digital collateral token offering instant, verifiable assurances for any kind of value transfer. Using Amp, networks like Flexa can quickly and irreversibly secure transactions for a wide variety of asset-related use cases.

The project, which launched in 2020, aims to provide a fast, efficient, and secure transaction platform. It claims to solve a number of network problems, including slow confirmation times, price volatility and broad adoption.

Amp claims to offer a straightforward but versatile interface for verifiable collateralization through a system of collateral partitions and collateral managers.

Collateral partitions can be designated to collateralize any account, application, or even transaction, and carry balances which are directly verifiable on the Ethereum blockchain.

Collateral managers are smart contracts that can lock, release and redirect collateral in these partitions as needed in order to support value transfer activities.

Amp supports a wide variety of use cases for collateralization, and also introduces the concept of predefined partition strategies, which can enable special capabilities such as collateral models through which tokens can be staked without ever leaving their original address.

Harmony is a blockchain platform designed to facilitate the creation and use of decentralized applications (DApps). The network aims to innovate the way decentralized applications work by focusing on random state sharding, which allows creating blocks in seconds.

eCash (XEC) is the rebranded version of Bitcoin Cash ABC (BCHA), itself a fork of Bitcoin (BTC) and Bitcoin Cash (BCH). It calls itself a “cryptocurrency that’s designed to be used as electronic cash.” eCash strictly aims to be a means of transaction used to pay for goods and services. The coin was rebranded on July 1, 2021, and has since tried to distinguish itself from its predecessor. The base units of eCash are called “bits” and replace the unwieldy decimal places of Bitcoin Cash ABC. Instead of sending 0.00001000 BTC, you would send 10 bits with eCash. ECash integrates a proof-of-stake (PoS) consensus layer called “Avalanche,” which is not to be mistaken for the blockchain Avalanche (AVAX). Upon rebranding, eCash announced that it would convert all BCHA coins to XEC at a ratio of one to one million.

The cryptocurrency’s developers have set their sights on three main improvements:

Scaling transaction throughput from 100 transactions per second to more than five million transactions per second

Improving the payment experience by reducing transaction finality time

Extending the protocol and establishing fork-free upgrades

Ren (REN) is an open protocol built to provide interoperability and liquidity between different blockchain platforms.

To learn more about this project, check out our deep dive of Ren.

Formerly known as Republic Protocol, Ren launched RenVM, its virtual machine mainnet, in May 2020, having completed a $34 million initial coin offering (ICO) in 2018.

The protocol’s native token, REN, functions as a bond for those running nodes which power RenVM, known as Darknodes.

Ren aims to expand the interoperability, and hence accessibility, of decentralized finance (DeFi) by removing hurdles involved in liquidity between blockchains.

Starting as an open-source project in 2017, IoTeX has built a decentralized platform whose aim is to empower the open economics for machines — an open ecosystem where people and machines can interact with guaranteed trust, free will, and under properly designed economic incentives.

With a global team of over 40 research scientists and engineers, IoTeX has built their EVM-compatible blockchain from scratch using the innovative Roll-DPoS consensus and launched in 2019 April, which has been running by 100+ delegates worldwide and has processed more than 10 million transactions already. On top of the IoTeX blockchain, the team has built the essential blocks of infrastructures to connect with Ethereum, BSC, and Heco blockchains such as ioPay wallet (https://iopay.me/) and ioTube bridge (https://iotube.org/), which serve ten thousands of users. IoTeX helps EVM-based DApps scale without concerning expensive gas fees!

Besides, middleware such as Decentralized Identity, Confidential Computing, and Secure Hardware has been built on top of the IoTeX blockchain. This has enabled the creation of self-sovereign devices such as Ucam, and real-world data oracles like Pebble. Ucam (https://ucam.iotex.io/) has been deployed to over 3000 households (http://iott.network/). Meanwhile, Pebble has been launched to more than 300 developers initially, and enables innovative Dapps to connect the physical world with the crypto world, such as real-world NFTs, weather derivatives and machine learning-as-mining.

Ontology is a project designed to bring trust, privacy, and security to Web3 through decentralized identity and data solutions. It is building the infrastructure to provide trusted access to Web3, allowing individuals and enterprises to rest assured that through regulatory compliant digital identity solutions, users and their privacy come first.

The Ontology blockchain is a high speed, low cost public blockchain. It is designed to bring decentralized identity and data solutions to Web3, with the goal of increasing privacy, transparency, and trust. To achieve this, users and enterprises are provided with the flexibility to build blockchain-based solutions that suit their needs, while also ensuring regulatory compliance. Through Ontology’s Ethereum Virtual Machine (EVM), Ontology ensures frictionless compatibility with Ethereum, the first step in the creation of the Ontology Multi-Virtual Machine and further interoperability for the chain.

At its launch, Ontology chose to forego the popular initial coin offering (ICO) model in favor of a series of community distributions and airdrops of its ONT cryptocurrency.

This helped to quickly establish both organic price discovery and a passionate community and helped the project to avoid subsequent regulatory scrutiny.

For example, for a brief period any person who signed up for the Ontology newsletter received an airdrop of free 1,000 ONT, which reached a value of $10 per token soon after the token became listed on major exchanges like Binance.

Ontology launched its own MainNet on June 30, 2018 and has been up and running smoothly since.
