The Research of Consortium Blockchain Dynamic Consensus Based on Data Transaction Evaluation

Aiming at the problem that consortium blockchains cannot elect a leader peer intelligently against real-time transactions and cannot satisfy the stability requirement of the data trading platform, this paper presents a consortium blockchain dynamic leader election. Based on the consensus protocols of Hyperledger Fabric, a transaction evaluation module calculating user score for each peer is introduced into the consortium blockchain. Peers elect the leader peer of the consortium blockchain according to user score dynamically, which improves the stability and security of reaching a consensus within the data trading platform.
