IEEE 3220.01:2025

New IEEE Standard - Active - Draft.
The consensus framework used in blockchain technology to make the blockchain state data consistent within the distributed network environment is defined by this standard. The definition of the blockchain consensus mechanism, the protocol standard followed, the type of consensus algorithm, and the relevant scenarios are the primary focus. A practical approach for blockchain projects, which helps develop appropriate consensus mechanisms faster and more comprehensively, is also provided by the standard. Regulators and users are also provided with an authoritative reference source.

This standard specifies a consensus framework for a blockchain system to help enable that the state data of the blockchain is consistent in the distributed network environment. It includes the conditions that a consensus mechanism should satisfy and corresponding definitions, the protocol standards to be followed, and different environment models that give a significant impact on the design of consensus mechanisms. Furthermore, it also describes types of mainstream consensus mechanisms and various application scenarios.
