摘要
由于网络设备的增多和传输环境的不确定性,消息时延同样具有不确定性,异步共识协议发挥出更多优势。Miller等于2016年提出第一个异步共识协议HoneyBadgerBFT,但其在实现高吞吐量的同时传输效率依然可以再优化。针对HoneyBadgerBFT中的广播协议进行改进,减少广播过程中的消息复杂度,同时增加可选的消息请求过程,以达到快速响应和高效传输的效果。
Due to the increase of network equipments and the uncertainty of the transmission environment,the message delay is also uncertain,and the asynchronous consensus protocol possesses more advantages.Miller et al proposed the first asynchronous consensus protocol HoneyBadgerBFT in 2016,but its transmission efficiency can be optimized furthermore while achieving high throughput.The broadcast protocol in HoneyBadgerBFT was improved by reducing the message complexity in the broadcast process,and adding optional message request process to achieve rapid response and efficient transmission.
