The Research on the Incentive Method of Consortium Blockchain Based on Practical Byzantine Fault Tolerant

In this paper, we use the credit mechanism of E-commerce platform to evaluate the transaction subject as user reviews, and evaluate the credit degree of the blockchain nodes based on the consensus algorithm of the consortium blockchain as node reviews, then associate the node credit score consisting of user and node reviews with the transaction cost to substitute the incentive effect of the block reward for ledger maintenance. According to the score-pricing strategy we will introduce later, this incentive method can ameliorate the problem of too concentrated bookkeeping permissions and improve the initiative of the accounting node.
