A blockchain consensus protocol based on proof-of-stake mechanism

By using a blockchain consensus protocol based on proof-of-stake mechanism, and employing distributed random beacons to select leader nodes and adopting a tree-structured rule, the complexities of block-producing node election and low transaction throughput in blockchain consensus protocols are solved, thus achieving efficient and secure blockchain consensus.

Abstract

The application relates to a blockchain consensus protocol based on a proof-of-stake mechanism, and proposes a new distributed random beacon (DRB) to select a leader for generating a block, which can resist attacks of malicious nodes and guarantee randomness and fairness of leader election. A new longest chain rule is proposed, so that honest nodes can select the same main chain for block synchronization, improve consensus efficiency and reduce chain bifurcation rate, and support dynamic availability. Compared with some previous blockchain consensus protocols, the blockchain consensus protocol based on the proof-of-stake mechanism has higher throughput, safety and consensus efficiency.
