Linguistic Knowledge Representation in DPoS Consensus Scheme for Blockchain

Abstract

The consensus scheme is an essential component in the real blockchain environment. The Delegated Proof of Stake (DPoS) is a competitive consensus scheme that can decrease energy costs, promote decentralization, and increase eciency, respectively. However, how to study the knowledge representation of the collective voting information and then select delegates is a new open problem. To ensure the fairness and eectiveness of transactions in the blockchain, in this paper, we propose a novel
