matching the user real-name authentication result with the inquired current block data, checking whether repeated user information is submitted, caching the transaction information into a local memory array when the repeated user information does not exist, and calculating sequence information of all users in the current block according to intelligent reduced internal setting logic;
generating new block data according to the sequence information, and taking the current block height, HASH, the block data and newly added transaction result block data as consensus information to initiate consensus to other transaction verification nodes;
when receiving the consistent confirmation messages fed back by 2f +1 other transaction verification nodes, writing the new block data into a block for persistence;
when the consistent confirmation messages fed back by 2f +1 other transaction verification nodes are not received within the period time, performing transaction rollback on the current transaction verification node, and clearing a local memory array;
wherein the number of transaction verification nodes in the blockchain is 3f + 1; f is the fault-tolerant number of the nodes, and the minimum is 1.
