Consensus protocol based on DPOS and aggregate signature

Consensus mechanism is the underlying technology of blockchain and the rule to maintain the normal operation of blockchain. Commonly used consensus mechanisms of blockchain public chain include POW, POS, DPOS, BFT and those mixed with many other mechanismsBy comparing the characteristics of several consensus mechanisms, the DPOS mechanism can generate more blocks with less computing power, and use BLS (Boneh-Lynn-Shacham) signatures for verification in the process of transaction verification to create a new consensus mechanism..Combined with DPOS mechanism, this paper deeply explored how to improve the efficiency of BLS signature in the process of blockchain transaction verification.
