Consensus Primitive

Definition

A consensus primitive is a fundamental building block or algorithm used to achieve agreement among distributed, independent computing nodes. These basic mechanisms allow a decentralized network to agree on a single, shared state or value despite potential failures or malicious actions. Examples include atomic broadcast or leader election protocols. Such primitives form the foundation for secure and consistent distributed systems like blockchains.
