PSO based Blockchain Committee Member Selection

Abstract

Implementing blockchain systems with less amount of decentralized computation power is a challenging task. One of the most essential solution in scaling the blockchain is selection of a trusted committee (TC). We intend to develop and apply a new method for selecting committee members depending on their reputation via particle swarm optimization (PSO) based update of the behavior of nodes. Indeed, this is the same concept as accumulating participants in the blockchain throughout the previous rounds of the consensus procedure.
