Definition ∞ A Pre-Consensus Mechanism is a preliminary agreement process that occurs before the final block consensus is reached on a blockchain. It involves participants agreeing on a provisional ordering or validation of transactions. This step helps streamline the subsequent main consensus algorithm.
Context ∞ This mechanism is often discussed in the context of improving blockchain performance and transaction finality. News related to new consensus protocols or scalability solutions may highlight the role of pre-consensus in accelerating transaction processing. It contributes to overall network efficiency and responsiveness.
