摘要
针对目前联盟链共识算法存在共识效率低和主节点选举过于集中的问题,提出一种基于信誉审查与工作量证明相结合的联盟区块链共识算法PRW(Proof of Review and Work)。引入了公有链中工作量证明的思想,通过同时考虑联盟区块链共识节点当前信誉审查情况与算力化的权益实现一致化共识,平衡系统集中化趋势,从而促进联盟区块链公平可持续发展。实验结果显示,经过改进后的PRW共识算法在提高节点出块效率的同时平衡了记账权竞争。
To address the problems of low consensus efficiency and over-centralized master node election in the current consensus algorithm of the alliance blockchains, we propose a consensus algorithm PRW(Proof of Review and Work) for the alliance blockchains based on the combination of reputation review and proof of work. The idea of proof of work in public blockchains is introduced to achieve a consistent consensus by considering both the current reputation review situation of the consensus nodes of the alliance blockchains and the arithmeticized equity to balance the centralization trend of the system, thus promoting the fair and sustainable development of the alliance blockchains. The experimental results show that the improved PRW consensus algorithm balances the competition for bookkeeping rights while improving the efficiency of nodes’ block out.
