Consensus Layer

Definition ∞ The Consensus Layer is the foundational component of a blockchain network responsible for coordinating and validating transactions across all participating nodes. It establishes the rules and mechanisms by which network participants agree on the validity of new blocks and the accurate state of the ledger. This agreement is essential for maintaining the integrity and immutability of the distributed ledger.
Context ∞ Developments in the Consensus Layer are frequently reported in relation to upgrades or shifts in blockchain architecture, such as the transition from Proof-of-Work to Proof-of-Stake mechanisms. Its efficiency and security directly influence transaction throughput, finality times, and the overall resilience of the network against attacks.
