Block Sequencing

Definition

Block sequencing is the process of arranging blocks of transactions in a specific, agreed-upon order within a blockchain. This ordering determines the chronological progression of the ledger, establishing the definitive state of all digital assets and smart contract executions. Proper block sequencing is essential for preventing double-spending and maintaining the integrity of transaction history across all network participants. It is a core function of consensus protocols, ensuring that every node records the same chain of events.
