Execution Model

Definition ∞ An execution model specifies the rules and environment governing how operations are processed within a computational system. Within blockchain contexts, this refers to the precise framework by which transactions are validated, ordered, and applied to the global state. It dictates the virtual machine, instruction set, and state transition logic that ensure deterministic and verifiable outcomes. Understanding a platform’s execution model is fundamental to comprehending its operational mechanics and security properties.
Context ∞ The evolution of blockchain technology frequently involves innovations in execution models to enhance throughput, reduce latency, or support more complex computations. Discussions often center on the trade-offs between serial and parallel execution models, or the use of different virtual machines beyond the EVM. Monitoring changes or proposals concerning a network’s execution model offers critical insight into its performance potential and developer capabilities.
