Hybrid Synchronous Model

Definition

A hybrid synchronous model combines elements of both synchronous and asynchronous communication in a distributed system. This model for distributed systems, including certain blockchain protocols, operates with periods of synchronized communication where messages are guaranteed to arrive within a known time bound, interspersed with periods where message delivery times are uncertain. It seeks to leverage the benefits of rapid agreement during synchronous phases while tolerating network delays or temporary partitions. This approach balances performance with resilience.
