Description: Sequential consensus is a consensus model where decisions are made sequentially, that is, in a specific and predefined order. This approach is fundamental in distributed systems, where multiple nodes must reach an agreement on the state of the system or the validity of a transaction. Unlike other consensus algorithms that may allow simultaneous or parallel decisions, sequential consensus ensures that each decision is made in a determined order, helping to avoid conflicts and ensuring system coherence. This model is especially relevant in environments where consistency is critical, such as in distributed databases and blockchain systems. The main characteristics of sequential consensus include determining the order of transactions, the ability to handle node failures, and the need for communication among participants to validate decisions. The relevance of this model lies in its ability to provide a robust and reliable framework for decision-making in systems where synchronization and coherence are essential, making it a valuable tool in the development of modern technologies that require a high degree of reliability and security.
