适用于海量数据处理的高吞吐量 联盟链共识算法 DMDR.

Blockchain technology can effectively solve the problem of trusted data sharing in the Internet of Things (IoT) scenario, but the main stream consensus algorithm may have a large delay, and it is difficult to process the mass heterogeneous data from multi-sources. To solve this problem, this paper proposed a dynamically multi-block double-round consensus algorithm (called DMDR). This algorithm split the two steps of transaction verification and packaging, and the way of transaction processing in advance and block generation in delay enabled the common node to take advantage of the waiting time to process the transaction and generate multiple blocks in a consensus, thus improving the data processing efficiency. This algorithm divided the nodes in the network into multiple clusters, and reduced the communication cost by the double-round consensus between each cluster and the whole system, and ensured the accuracy of the consensus results based on the mutual verification of the points in the cluster. The simulation results show that the throughput of the proposed algorithm is better than that of PoW and PBFT, and it still has a considerable transaction throughput in small delay.
