REI Network is a blockchain framework that strives to adapt to the evolving trends of the blockchain industry. It seeks to provide a lightweight, Ethereum-compatible platform with high performance and minimal transaction costs. The network is built on a unique design of tokenomics, which aims to lower resource consumption, providing a more user-friendly solution. REI Network also focuses on speed, with an average block time of 3 seconds and a transaction per second (TPS) rate of over 3000. This focus on speed aims to provide users a faster experience without compromising decentralization.

REI Network operates through a unique staking and replacement system for on-chain resources, which allows users to complete on-chain transactions with minimal costs. This system is designed to be efficient and economical, with no Proof of Work (PoW) but a green-based Delegated Proof of Stake (DPoS) + Byzantine Fault Tolerance (BFT) consensus mechanism. The network also features an abstract consensus module built into its cross-chain mechanism, which can be easily integrated to become a chain-making tool. Additionally, REI Network supports developers with resources and support to encourage ecosystem building.

REI Network supports a wide range of potential use cases, particularly in the areas of decentralized finance (DeFi), GameFi, and Non-Fungible Tokens (NFTs). The network's compatibility with the Ethereum Virtual Machine (EVM) and Ethereum infrastructure allows for seamless migration of Ethereum applications. Developers can build various decentralized applications (DApps) on REI Network, including decentralized exchanges, play-to-earn games, NFT marketplaces, non-custodial lending solutions, and next-generation stablecoins. The network also encourages community participation in governance and proposal submission through its Decentralized Autonomous Organization (DAO).

REI Network's history began with the release of the GXChain 2.0 developer preview version in the second quarter of 2021. The network underwent several upgrades and enhancements throughout the year, including the introduction of stacking and slashing modules for second-level block confirmation and the implementation of an economic model. In the fourth quarter of 2021, GXChain 2.0 was officially renamed REI Network, and the two networks were interconnected and cross-chained through GXC-Relay. The network's rebranding from GXChain to REI Network marked the singularity of its evolution, and it has since focused on ecosystem infrastructure construction, brand building, and the development of its stake-based economic model.
