Rapid responsive and efficient multi-valued Byzantine consensus scheme

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.
