It is important to have a record of attribution in storage for slashing replay protection. We also maintain a [whitelist of merkle tree hooks](`b14f997810/solidity/contracts/libs/CheckpointLib.sol (L50-L54)`) such that validators cannot simply lie about this part of the checkpoint and circumvent fraud proofs. ### Backward compatibility Yes ### Testing Unit Tests	4 months ago
