Sequential Block Production

Definition ∞ Sequential Block Production describes a blockchain architecture where blocks are created and added to the chain one after another in a strictly ordered sequence. This ensures a clear, linear progression of transactions and prevents simultaneous block creation by multiple validators. The sequential nature simplifies consensus and provides a definitive order for all network events. It is a fundamental characteristic of many established blockchain protocols.
Context ∞ Sequential Block Production is a foundational element in many existing blockchain designs, offering strong guarantees of transaction finality and ordering. However, it can present limitations for scalability, as only one block can be added at a time. Discussions often address the trade-offs between strict sequentiality and parallel processing for higher transaction throughput. Future protocol designs may explore hybrid approaches to balance security with performance requirements.
