Sequential Operations

Definition ∞ Sequential operations refer to a series of tasks or processes that are executed in a strict, predetermined order, where each step must fully complete before the subsequent one can begin. This ensures a precise and predictable flow of execution. The outcome of one operation directly influences the input or context for the next. This ordered execution is fundamental for maintaining data consistency.
Context ∞ In blockchain transaction processing and smart contract execution, sequential operations are fundamental to maintaining the integrity and determinism of the distributed ledger. The specific order in which transactions are processed directly impacts the final state of the blockchain. Ensuring proper sequencing is critical for preventing race conditions, front-running, and other vulnerabilities that could compromise the fairness and security of decentralized applications.
