Abstract

Practical Byzantine Fault Tolerance (PBFT) for alliance chains is limited by high communication cost, which makes it unsuitable for more consensus networks. In view of the limitation of PBFT algorithm, a consensus algorithm of RPBFT is proposed. The RPBFT algorithm introduces RSA (Rivest-Shamir-Adleman) signature on the basis of PBFT algorithm, which not only increases the security, but also solves the high communication problem of PBFT algorithm and reduces the communication complexity to O(n). RPBFT also optimizes the consensus phase, shortens the consensus process and improves the efficiency of consensus. Experimental results show that RPBFT not only can effectively reduce the consensus delay, but also can improve the transaction throughput and scalability, which makes RPBFT more suitable for complex networks.
