Definition ∞ Consensus Layer Integrity describes the condition where a blockchain’s consensus mechanism operates as intended, accurately validating and ordering transactions without any unauthorized alteration or compromise. This state is fundamental for the network’s security and trustworthiness. It guarantees the reliability of the ledger.
Context ∞ Maintaining the integrity of the consensus layer is paramount for any blockchain’s credibility and security. Reports frequently highlight events that test this integrity, such as potential attacks or software defects. Protocol improvements often focus on strengthening the network’s ability to reach and sustain agreement on the correct state of the ledger.
