BNB Chain
A Binance Smart Chain client based on the go-ethereum fork
The goal of Binance Smart Chain is to bring programmability and interoperability to Binance Chain. In order to embrace the existing popular community and advanced technology, it will bring huge benefits by staying compatible with all the existing smart contracts on Ethereum and Ethereum tooling. And to achieve that, the easiest solution is to develop based on the go-Ethereum fork, as we respect the great work of Ethereum very much. Binance Smart Chain starts its development based on go-ethereum fork. So you may see many toolings, binaries and also docs are based on Ethereum ones, such as the name “geth”. But from that baseline of EVM compatible, Binance Smart Chain introduces a system of 21 validators with Proof of Staked Authority (PoSA) consensus that can support short block time and lower fees. The most bonded validator candidates of staking will become validators and produce blocks. -
