# Welcome to REI Network

REI Network is not a new project, but an upgraded version of GXChain. REI was developed to better adapt to the development trend of the blockchain, and to achieve a lightweight, Ethereum compatible, higher performance, and no fee blockchain framework

## New Features

* Compatible with **EVM**
* Compatible with **Ethereum's RPC** and **Websocket** interfaces, and can support **GRPC** in the future
* Rewrite the network module and use **Libp2p** instead of **Devp2p** (current Ethereum client solution), because we believe that Libp2p has better standards and can achieve better versatility and scalability
* Realize lower resource consumption through the design of tokenomics ([**Gas Free**](https://docs.rei.network/rei-dao/guides/stake-for-free-gas))
* Realize [**Systems contracts**](https://docs.rei.network/developer/system-contracts) that can be soft-forked and upgraded. These contracts include: Staking/Slashing, ResourceManager and IBC contracts, etc.
* Achieve a more efficient and more random consensus: **DPoS+BFT**, to ensure decentralization and be more green power
* Realize the **abstract consensus module**, so that the code of REI Network can be easily combined and become a chain-making tool
