Blockchain technology is an emerging distributed ledger technology that has exploratory applications in many areas. The consensus algorithm, as the core module of the blockchain, has an important impact on the security, scalability, and efficiency of the blockchain network. The consensus algorithm is also a popular topic in current blockchain technology research. In existing consortium blockchains and public blockchains, the blockchain has low efficiency or poor fault tolerance because of the limitations of the consensus algorithm. To both ensure the fault tolerance of the blockchain and improve the scalability and throughput, in this paper, we propose a new type of consensus algorithm: mixed Byzantine fault tolerance (MBFT). MBFT uses sharding and layered technology. MBFT functionally partitions the nodes that participate in the consensus process and improves the scalability and efficiency without sacrificing security. MBFT also introduces a random node selection mechanism and a credit mechanism to improve security and fault tolerance. We analyze the security and experiment on transaction throughput in a real network environment. The results prove that MBFT has good security and scalability and high throughput.

一种新颖的无通信微电网经济调度方法


区块链技术是一种新兴的分布式账本技术，在多个领域都有探索性应用。共识算法作为区块链的核心模块，对区块链网络的安全性、可扩展性、高效性有着重要影响。共识算法也是当前区块链技术研究的热门话题。在现有的联盟链和公有链中，由于共识算法的限制，区块链效率较低或容错性较差。为了既保证区块链的容错性，又提高可扩展性和吞吐量，本文提出了一种新型共识算法：混合拜占庭容错（MBFT）。 MBFT使用分片和分层技术。 MBFT对参与共识过程的节点进行功能分区，在不牺牲安全性的情况下提高可扩展性和效率。 MBFT还引入了随机节点选择机制和信用机制来提高安全性和容错性。我们在真实的网络环境中分析了安全性并进行了交易吞吐量的实验。结果证明MBFT具有良好的安全性和可扩展性以及高吞吐量。
