Abstract

To address the limitations of existing asynchronous consensus algorithms, such as high communication overhead during multiple rounds and random selections due to the lack of reputation mechanism in random sampling, this paper proposed an efficient asynchronous Byzantine fault-tolerant algorithm called PenguinBFT. Firstly, this paper broadcasted transactions directly during transaction broadcasting to significantly reduce consensus communication overhead. Secondly, this paper introduced a node reputation evaluation mechanism to select a block generator from a relatively stable node set, which reduced the number of random selections required. Finally, this paper partitioned network nodes and different nodes access different partitions for transaction recovery when necessary, reducing communication overhead and improving transaction recovery efficiency. Experimental results demonstrate that when the number of nodes exceeds 64, the PenguinBFT algorithm shows more than 50% improvement in communication overhead, throughput, and transaction confirmation delay when compared to the HoneyBadgerBFT, DumboBFT, and DispersedLedger algorithms.
