Network Synchrony Model

Definition ∞ A network synchrony model describes the assumptions made about the timing and reliability of message delivery within a distributed system. In blockchain design, this model dictates how quickly nodes are expected to receive and process information from one another. It influences the choice of consensus mechanism and the overall security properties of the network. The model defines the degree of coordination among participants.
Context ∞ The network synchrony model is a foundational element in blockchain protocol design, directly impacting transaction confirmation times and resistance to certain attacks. Debates often compare synchronous, asynchronous, and partially synchronous models, each offering different trade-offs in terms of performance and security guarantees. Understanding this model is critical for evaluating a blockchain’s operational characteristics and resilience.
