Summary:As the core of blockchain technology, the consensus mechanism determines the performance, scalability, and security of the blockchain system. In view of the current performance, scalability, and the high cost of the incentive mechanism used to maintain the security of the blockchain Question, a trust-based Dual-layer Scalable Consensus Protocol (TDSCP) is proposed. First, a dual-layer collaborative trust model and consensus algorithm are designed through a structured network. Among them, the trust model According to the trust value of the node, it is determined whether it can obtain the right to generate blocks, avoiding high mining costs; secondly, the double-layer consensus algorithm in the partition is used to improve the consensus efficiency, expand the number of nodes participating in the consensus, and avoid the problem of system centralization. ; Finally, combining verifiable random functions and multi-level graph partitioning algorithms to partition nodes can effectively prevent malicious nodes from g
