What Is Reef (REEF)?

Reef, a layer 1 blockchain leveraging Parity's Substrate technology, emerged in 2019 under the stewardship of Denko Mancheski. Initially conceived as a DeFi platform, it has since matured into a fully operational blockchain network. Operating on Nominated Proof of Stake (NPoS), Reef delegates transaction validation to validators chosen by nominators who stake REEF tokens. Each successful block processing yields rewards shared among the validator and 64 nominators. To facilitate network enhancements, a Technical Council, determined via Proof of Commitment (PoC) consensus, initiates proposed changes.

REEF, the blockchain's native cryptocurrency, serves dual purposes: governance participation and network transaction fee settlement. Available for acquisition on Binance, REEF can be obtained through debit/credit card transactions or cryptocurrency exchanges.


Reef, established in 2019 by Denko Mancheski, underwent a rebranding in November 2021, transitioning from Reef Finance to a comprehensive blockchain platform. Offering diverse applications such as NFTs, DeFi, smart contracts, and GameFi, Reef facilitates seamless token transfers between ERC-20 tokens on Ethereum and BEP-20 tokens on the BNB Chain through its liquidity bridges.

Exploring the Reef Blockchain

Developed with Parity's Substrate software development kit, Reef stands as an interoperable blockchain within the broader Web3 network. Leveraging Ethereum Virtual Machine (EVM) compatibility, it streamlines the porting of EVM-based DApps, particularly benefiting Solidity-savvy developers.

Reef implements NPoS for block production and PoC for Technical Council selection. It adopts a fee-burning model, including smart contract fees, while compensating Validators from a fixed rewards pool. This design discourages inefficient contract creation, mitigating network congestion.

The Governance Framework of Reef Blockchain

Unlike Bitcoin and Ethereum, Reef implements a governance system that enables direct upgrades and avoids stagnation. This model involves collaboration between two entities: the Technical Council and Validators.

  • The Technical Council, elected through the PoC consensus mechanism, oversees network updates, focusing on technical parameters like block size and throughput. Changes require majority approval from the Council.
  • Validators, chosen via NPoS, validate transactions and maintain network integrity. Rewarded from an inflation pool, they face stake penalties for misconduct. Nominators play a crucial role in selecting Validators.

Reef Staking Mechanics

In the NPoS system, both validators and nominators engage by staking REEF. Nominators accrue additional REEF by supporting competent validator candidates, sharing rewards upon successful block processing. However, misbehaving validators trigger stake penalties for nominators. Staked REEF remains locked until the nominator withdraws their validator nomination, effective after roughly 24 hours, with a subsequent 28-day waiting period for stake retrieval.

Not all nominated validators enter the active set due to algorithmic limitations, typically allowing support for one validator per era. Validators can distribute rewards to up to 64 nominators, prioritizing those with the highest stakes. Oversubscribed validators only reward the top 64 nominators, although all stakes contribute to validator selection. The validator set computation occurs off-chain, with nominators scaled according to stake size.

Exploring the Reef Ecosystem

Beyond its core blockchain, Reef boasts an array of supplementary tools and services.

Reef Web Wallet 

Reef Web Wallet functions as a multifaceted platform, serving as a crypto wallet, Decentralized Exchange (DEX), and token generator. Users can engage in token swaps, transfers, and liquidity pooling akin to ReefSwap, accessible via the Reef Browser Extension.

Understanding REEF Token

REEF is the native cryptocurrency of the Reef ecosystem. It facilitates transaction fee payments through its gas system and participates in on-chain governance, encompassing both NPoS and PoC consensus mechanisms. Initially launched as an ERC-20 token on Ethereum and a BEP-20 token on BNB Smart Chain, REEF can now be seamlessly converted at a 1:1 ratio within the Reef network.


While Reef initially gained recognition for its DeFi origins, it has since evolved into a comprehensive ecosystem and operational blockchain. With ongoing developments, including burgeoning smart contracts and DApps, Reef exhibits promising potential for further expansion and innovation.
