Definition ∞ Sequential composition refers to the arrangement of operations or processes in a defined order, where each step must complete before the next one begins. This design ensures predictable execution and maintains a clear flow of control within a system. It is a foundational concept in programming and system architecture.
Context ∞ In blockchain and smart contract development, sequential composition is crucial for ensuring the correct and predictable execution of transactions and programmatic logic. News often highlights the importance of precise sequencing in preventing exploits or unintended outcomes within decentralized applications. Understanding this ordered execution is essential for verifying the integrity of on-chain operations.
