Definition ∞ System Level Execution involves the direct operation and processing of commands and code at the core infrastructure layer of a computing system or network. This includes the underlying mechanisms that run software, manage resources, and facilitate communication between components. It represents the fundamental functional processes.
Context ∞ In blockchain and decentralized systems, system level execution refers to the precise manner in which smart contracts and protocol rules are processed by nodes. News often discusses the efficiency and security of these execution environments, particularly in the context of virtual machines and layer-2 solutions. Optimizing system level execution is critical for achieving higher transaction throughput and lower costs.
