The current blockchain requires higher stability and efficiency. However, leaderBFT consensus and leaderlessBFT consensus exist three problems:dominant replica failure, transaction interruption, high communication overhead and latency.And whether leaderBFT consensus or leaderlessBFT consensus, there isn’t a very good solution. It’s urgent to leverage the advantages of both consensus to enhance blockchain performance.To solve the problems, this paper proposes the ATBFT consensus protocol. ATBFT elect the dominant replica through reputation value to ensure higher reliability. In addition, ATBFT has an automatic switching mechanism between leaderBFT consensus and leaderlessBFT consensus. The protocol can automatically elect the consensus type according to the current network conditions, effectively utilizing the idle time of the view change to generate more blocks. In addition, it can guarantee the execution of the entire consensus process to ensure that the tx1 -transactions are uninterrupted. Finally, ATBFT decomposes the blocks, the consensus is performed only through the block header, and the commitment and execution phase of a tx is performed through a linearly propagated block body. After experimental evaluation, ATBFT has higher usability and practicality.
