What is BNB Chain?
BNB Smart Chain is an EVM-compatible blockchain that has run since 2020. It uses Proof of Staked Authority (PoSA) with a set of 21 validators chosen from the most bonded candidates. BNB pays gas and staking, and block rewards come from transaction fees rather than inflation.
BNB Chain pros and cons
- Full EVM compatibility with Ethereum tooling
- No inflation of BNB; block rewards come from fees
- Client is a public go-ethereum fork on GitHub
- Only 21 active validators under PoSA
- Validators are the most bonded candidates, so stake size decides the set
- Finality takes around 6 seconds per BNB Chain's FAQ, slower than block time
