【摘要】 采用有向无环图结构的区块链共识机制能并行执行交易，但效率与稳定性较差。因此一些共识机制采用联盟链的方式处理交易。本文设计并提出基于有向无环图的并行存储结构，通过并行存储结构实现事务块认证机制（TBCM）的共识机制，由此TBCM共识机制能有效提升联盟链整体对大量交易的并行处理能力。TBCM中采用联盟链的方式组织节点，验证节点组验证网络中生成的交易块，采用并行存储结构的网络中的同步用户不必处理整个网络的交易负载，由验证节点组并行处理网络中的区块。由此结构设计的共识机制使联盟链系统具备并行处理事务的能力，以此提高交易的实时性。TBCM拥有并行性实时交易的优势，能实现更高的稳定性和交易确认效率。更多还原

【Abstract】 The blockchain consensus mechanism with directed acyclic graph structure can be executed transactions in parallel, but its efficiency and stability are poor. Therefore, some consensus mechanisms deal with transactions in the way of alliance chain. In this paper, a parallel storage structure based on directed acyclic graph is designed and proposed to realize the Transaction block confirmation mechanism(TBCM) consensus mechanism through this storage structure. Therefore, TBCM consensus mechanism can effectively improve the parallel processing ability of the alliance chain for a large number of transactions.In TBCM, the nodes are organized in the way of alliance chain, and the verification node groups verifie the transaction blocks generated in the network. The synchronous users in the network of parallel storage structure do not have to deal with the transaction load of the whole network, and the verification node group processes the blocks in the network of parallel. The consensus mechanism designed by this structure makes the alliance chain system have the ability to process transactions in parallel, so as to improve the real-time performance of transactions. TBCM has the advantage of parallel real-time transaction, and can achieve higher stability and transaction confirmation efficiency.更多还原
