Multi-Valued Agreement

Definition

Multi-valued agreement is a distributed computing problem where a set of processes must agree on one value from a range of proposed values, even if some processes fail or behave maliciously. Unlike single-valued agreement, which seeks consensus on a specific binary choice, this protocol allows for a selection from a broader set of options. It is a more generalized form of consensus crucial for complex decentralized applications. This agreement type finds application in various distributed decision-making scenarios.
