The metrics in this report will focus on BNB Smart Chain (BSC). BSC is an EVM-compatible, layer-1 blockchain secured by a form of Proof-of-Staked-Authority (PoSA) that combines aspects of Proof-of-Authority (PoA) and Delegated Proof-of-Stake (DPoS). In PoSA on BSC, the validator set is of fixed size and is elected by stake weight (staked plus bonded). In addition, validators must continue staking assets to secure the network, and validators chosen to produce blocks are rotated (not based on stake weight).
