Beacon Chain Finality signifies the point at which transactions recorded on the Ethereum Beacon Chain are irreversibly confirmed and cannot be altered. This state occurs when a supermajority of validators, specifically two-thirds of the total staked Ether, attest to the same block. Achieving finality guarantees the integrity of the chain’s history and prevents malicious reorganizations. This mechanism is central to the security and reliability of Ethereum’s Proof-of-Stake consensus.
