Definition ∞ Sequential processing refers to the execution of computational tasks or transactions one after another in a specific, predetermined order. In many blockchain architectures, transactions are processed sequentially within a block, and blocks themselves are added sequentially to the chain. This method ensures determinism and simplifies the ordering of operations.
Context ∞ The limitations of sequential processing are a primary driver for scalability solutions in blockchain technology, with news frequently discussing parallel execution or sharding. While it ensures consistency and simplifies state management, it can limit transaction throughput and increase latency. Innovations in network architecture often aim to move beyond strict sequential models to enhance performance.
