【Abstract】Distributed ledger technology (DLT) has emerged as a key and effective technology which has caught the attention of variety of disciplines and is capable of changing lots of sciences and related industries. Selecting the transactions of members in DLT-based technologies such as blockchain, especially in finance, is essential and vital. Therefore, in this paper, we present a novel framework for selecting members' transactions through trust and reputation models called the reputation-based consensus framework (RCF), so that by combining trust and reputation models with blockchain, the target node (or verifier), which has the highest reputation based on its transactions history, is selected to create and publish the current block of blockchain. We have also provided a state machine model to accurately describe the behavior of the RCF. In addition, the RCF algorithms are presented and a prototype is developed based on it. The results of simulation and performance and security analysis proved that RCF leads to fair selection of transactions, improves scalability and throughput, and can resist against attacks such as Sybil and malicious behaviors.
