摘要：SCP is a recent effort that focuses on improving the scalability of blockchains by combining PoW and BFT. However, there exist security problems and performance limitation in SCP. In this paper, an improved blockchain consensus protocol ISCP with higher security and better efficiency is presented. We adopt a decentralized multipartition consensus model to address the security problem in SCP while keeping the computational-scalable feature of the protocol. We also propose a novel intra-committee consensus algorithm which is more efficient than BFT in intra-committee consensus. We analyze and prove that ISCP has higher security and better efficiency than SCP. Experimental results show that the novel intra-committee consensus protocol can significantly reduce consensus delay and greatly increase throughput of the network. ? 2019, International Journal of Network Security.
