Distributed Consensus Protocol

Definition ∞ A distributed consensus protocol is a set of rules that enables independent computers in a network to agree on a single data value or state. This protocol is essential for decentralized systems like blockchains, ensuring that all participating nodes maintain an identical and accurate copy of the ledger, even if some nodes fail or attempt to act maliciously. It forms the backbone of data integrity and security, allowing for trustless operation across a geographically dispersed network. Examples include Proof-of-Work and Proof-of-Stake, which coordinate agreement without a central authority.
Context ∞ Distributed consensus protocols are continuously being researched and refined, with significant news coverage on advancements in efficiency, scalability, and security. The transition of major blockchains to more resource-efficient protocols, such as Proof-of-Stake, highlights the ongoing evolution in this area. These protocols are central to the operational integrity and future development of all decentralized digital asset systems.
