Description: Synchronous consensus is a consensus model in distributed systems where all nodes must agree on the state of the system at the same time. This approach is fundamental to ensuring data consistency and integrity in environments where multiple participants must collaborate and make decisions simultaneously. In this model, each node must receive and process the same information within a specific time interval, which implies that communication between nodes must be fast and efficient. The main characteristics of synchronous consensus include the need for a global clock or timing mechanism that allows all nodes to synchronize their actions. This contrasts with asynchronous models, where nodes can operate independently and do not require temporal agreement. The relevance of synchronous consensus lies in its ability to prevent inconsistency situations, such as those that may arise in systems where nodes have different views of the system’s state. This model is particularly useful in critical applications where accuracy and reliability are essential, such as in banking systems, telecommunications networks, and distributed databases. In summary, synchronous consensus is a cornerstone in the theory of distributed systems, providing a robust framework for coordinated decision-making among multiple nodes.
