根据应用场景的不同，一般分为公有链、联盟链和私有链。由于公有链完全去中心化的性质导致其无法满足企业的需求，所以在实际应用中企业往往选择部分去中心的联盟链。共识机制是区块链的引擎与核心。目前，主流的共识机制主要针对公有链提出，难以适用于联盟链与私有链。在此背景下，论文为联盟链提出一种共识机制。该共识机制不仅解决传统共识效率低的问题，而且在一定程度上可以应对拜占庭容错。

Abstract： With the popularity of bitcoin， blockchain technology has become the mainstream of current rearch field. Block chain system is generally divided into public blockchain， consortium blockchain and private blockchain. Becau of the completely decentralized nature of public blockchain， it can not meet the needs of enterpris， so in practical applications enterpris often choo part of the decentralized consortium blockchain. Connsus mechanism is the engine and core of blockchain. At prent， the mainstream connsus mechanism is mainly for the public chain， and it is difficult to
apply to the consortium blockchain and private chain. Under this background， this paper propos a connsus mechanism for the consortium blockchain. This connsus mechanism not only solves the inefficiency of traditional connsus， but also can deal with Byzantine failures.
