摘要

摘要

En 中文
当前区块链需要更高的稳定性和效率。然而，leaderBFT共识和leaderlessBFT共识存在三个问题：主导副本故障、交易中断以及高通信开销和延迟。无论是leaderBFT共识还是leaderlessBFT共识，目前都没有很好的解决方案。亟需利用两种共识类型的优势来提升区块链性能。为解决这些问题，本文提出了ATBFT共识协议。ATBFT通过声誉值选举主导副本以确保更高的可靠性。此外，ATBFT具有leaderBFT共识和leaderlessBFT共识之间的自动切换机制。该协议可根据当前网络条件自动选举共识类型，有效利用视图变更的空闲时间生成更多区块。此外，它能保证整个共识过程的执行，确保tx2-交易的连续性。最后，ATBFT将区块分解：仅通过区块头进行共识，而交易的提交和执行阶段通过线性传播的区块体完成。根据实验评估，ATBFT具有更高的可用性和实用性。
