PoS共识算法在多方分布式账本上的应用研究

Research on the Application of PoS Consensus Algorithm on Multi-Party Distributed Ledger

区块链是分布式数据存储、共识算法、加密算法等计算机技术的新型应用模式。区块链证明了拜占庭容错的共识算法的可行性,这对于多中心、去中心化的企业应用具有重要意义。通过对PoS共识算法的评估发现,PoS共识算法不仅决定“谁来写”的问题,并且还能确定“写的东西是不是真实”,实现多方账本数据真实、可靠、一致。鉴于多方分布式账本传统约定时间对账清算中存在效率不高、账本不一致引发信任危机等问题,以多方企业的物联网共享数据和金融行业多方交易转账为例,提出基于PoS共识算法的多方分布式账本解决方案。

Blockchain is a new application model of computer technology such as distributed data storage,consensus algorithms,and encryption algo-rithms.The blockchain proved the feasibility of byzantine fault tolerant consensus algorithm,which is of great significance for multi-centric and decentralized enterprise applications.Through the evaluation of the PoS consensus algorithm,it is found that the PoS consensus algo⁃rithm not only determines the problem of"who will write",but also determines whether"what is written is true or not",and realizes the authenticity,reliability,and consistency of multi-party ledger data.In view of the problems such as low efficiency in the traditional pre⁃scribed time reconciliation and settlement of multi-party distributed ledgers and the trust crisis caused by inconsistent ledgers,this paper proposes a multi-party distributed ledgers solution based on PoS consensus algorithm,taking the internet of things sharing data of multiparty enterprises and multi-party transaction transfer of financial industry as examples.
