Altcoins: Reef Coin (REEF) What Is It?

TL;DR
Reef is a layer 1 blockchain built using Parity’s Substrate technology. Launched in 2019 by Denko Mancheski, it's undergone a significant transformation from a DeFi platform to a fully-functioning blockchain.
The network uses Nominated Proof of Stake (NPoS) to process valid blocks of transactions. Nominators stake REEF behind validators with hopes of being selected into the active validator set. When a validator successfully processes a block, a reward is shared between them and 64 nominators.
For network upgrades, a Technical Council nominated via a Proof of Commitment (PoC) consensus mechanism proposes changes.
The blockchain's native cryptocurrency, REEF, is used to take part in governance and pay network transaction fees. You can purchase REEF on Binance with a debit/credit card or by trading for it with other cryptocurrencies.
Introduction
Reef is a Substrate-based, layer 1 blockchain founded in 2019 by Denko Mancheski. In November 2021, the project rebranded from Reef Finance to reflect its development from a Decentralized Finance (DeFi) platform to a fully functioning blockchain.
Like other networks, Reef offers use cases for NFTs, DeFi, smart contract development, and GameFi. Reef also provides liquidity bridges to move ERC-20 tokens between Reef and Ethereum, and BEP-20 tokens between Reef and the BNB Chain.
The Reef blockchain
Reef was developed using Parity’s Substrate software development kit. This aspect makes it interoperable with Polkadot parachains and part of a larger Web3 network of chains. Reef is Ethereum Virtual Machine (EVM) compatible, making it easy to port EVM Decentralized Applications (DApps) and build on, especially for users experienced with Solidity (Ethereum’s primary coding language).
The blockchain uses a NPoS consensus mechanism for block production and Proof of Commitment (PoC) for electing members to a Technical Council. Reef burns all fees on the network (including for smart contracts), and Validators are paid from a fixed rewards pool. This removes any economic incentive to create inefficient contracts with high fees, which can cause congestion on a network.
How Reef governance works
Compared to Bitcoin (BTC) and Ethereum (ETH), Reef has implemented a governance model that provides direct methods for upgradeability. Bitcoin and Ethereum rely on their Proof of Work (PoW) miners to decide which upgrades to accept. This method leads to stagnation and an unwillingness to improve scalability, harming mining profits.
Reef, however, allows two groups to work together in implementing changes to the network: a Technical Council and Validators.
The Technical Council
The Technical Council approves and reviews network updates. These members are elected via the PoC consensus mechanism. PoC has similarities with Delegated Proof of Stake but incorporates a long bonding period of at least a year. Anyone, therefore, who stakes Reef to nominate a Technical Council member is incentivized to vote for competent members with longevity.
Technical Council members make decisions on block size, block time, throughput, and other technical parameters. Making these changes on-chain is possible through a majority approval from the Technical Council.
Validators
Validators process blocks of legitimate transactions and run a node. These are elected using the NPoS consensus mechanism. As previously mentioned, all transaction fees are burned on the Reef. This means that validators are paid rewards from a yearly inflation pool (set roughly at 8%).
Validators are selected by nominators, which we'll discuss shortly. If a validator acts maliciously or misbehaves, they will have their stake slashed.
Staking on Reef
Both validators and nominators in NPoS must stake REEF to take part. By staking REEF, nominators earn more REEF by picking good validator candidates. If the validator is elected into the active set and successfully processes blocks, the nominator can share their rewards. If the validator misbehaves, the nominator will lose some of their stake, and the validator will be slashed.
Staked REEF is locked until the nominator decides to remove their validator nomination, which becomes effective in the next era (roughly 24 hours). The nominator must then wait 28 days for their stake to be returned.
Active validator set and rewards
Not every nominated validator will make it into the active set of validators. In most cases, an algorithm will only allow you to actively support one successful validator per era. This is the case even if you staked behind multiple ones chosen for the active set.
Each validator can only support payouts to 64 nominators. If a validator has more nominators than this, they are oversubscribed. Only the top 64 nominators by the amount staked will receive rewards.
Even if they don't receive rewards, the other nominators' stakes will still count towards the total staked behind a validator. The set of validators is computed off-chain, with some nominators eliminated according to the size of their stake.
The Reef ecosystem
Reef isn’t only made up of its blockchain. It has an ecosystem of tools and services that complement its layer 1 network.
Reef Web Wallet
Reef Web Wallet is a crypto wallet, Decentralized Exchange (DEX), and token creator on Reef. You can swap, send, and pool tokens here, much like on ReefSwap. You'll need to download and install the Reef Browser Extension to use the app.
ReefScan
ReefScan is a blockchain explorer where users can browse transactions, wallet IDs, smart contracts, and other on-chain information. It uses a similar format to Etherscan or BscScan, making it simple to use. You can also interact with Reef smart contracts via Reefscan.
ReefSwap
ReefSwap is a DEX offering a swapping service for Reef tokens. It uses the familiar Uniswap V2 model and requires users to access it via the Reef browser extension. This is due to Reef being Substrate-based. Users can also claim an EVM wallet address and assign it to their Reef Account.
What is REEF?
The REEF token is Reef's native cryptocurrency. It can be used to pay transaction fees on the network using its gas system and in on-chain governance. This includes both the NPoS and PoC consensus mechanisms.
REEF was originally minted as an ERC-20 token on Ethereum and BEP-20 on BNB Smart Chain. However, you can now convert it 1:1 on Reef.
Where can I buy REEF?
Binance offers two ways to purchase REEF. First, you can buy REEF with a credit or debit card in selected fiat currencies. Visit Binance's [Buy Crypto with Debit/Credit Card] page, choose the currency you want to pay in, and select REEF in the bottom field.
Click [Continue] to confirm your purchase and follow the instructions given.
You can also trade cryptocurrencies for REEF, including BUSD, BTC, USDT, and TRY. Navigate to Binance's Spot view and type REEF in the trading pair search field. This will display all the available trading pairs. For more information on using the Exchange view, visit our How to Use TradingView on the Binance Website guide.
Conclusion
For many, Reef is still well-known for its original DeFi business model. However, Reef has made significant development changes and has grown into a more developed ecosystem and fully functioning blockchain. The blockchain’s new developments are still young, giving it great potential for growth in the number of smart contracts and Decentralized Applications (DApps) that can be deployed on the network.
