As shown in fig. 2, two nodes are transacted, and the accounting book management method comprises the following steps:
s1, establishing a block chain application system, deploying a plurality of nodes, performing point-to-point transaction among user nodes to obtain transaction data, obtaining first transaction data after the transaction of the first node, and obtaining second transaction data after the transaction of the second node;
and S2, recording the first transaction data including the first transaction big data and the first transaction small data and the second transaction data including the second transaction big data and the second transaction small data into the first node and the second node to the corresponding first node block and second node block respectively, wherein each node has an account book, the same node blocks in the same channel are provided, the capacity of each block can be configured, the blocks are timed-out blocks, the block time is generally configured for 5-10 seconds, and all transactions in the time are packed into the same block. It is not necessary to trade one block, and the first node block and the second node block refer to two node blocks respectively.
The block chain account book is maintained by the nodes, not by the sequencing service cluster, only the complete block chain information can be found on the peer nodes, and the sequencing service cluster is only responsible for sequencing the transaction and only retains a part of the block chain information in the processing process. The node in the application system is a logical concept and is not necessarily a physical device, but for a designer of a production environment, the node in the application system cannot be deployed on a machine together with the sequencing node.
The endorsement node and the validation node may be deployed on the same machine for decoupling of the system architecture, improving scalability, and improving security through host isolation. And after the transaction processing is finished, signing the transaction information and returning the signature to the client. At this time, no consensus is achieved between the two endorsement nodes of the transaction information, and the consensus between the first node and the second node adopts the pbft consensus and is inserted into the application system in a configuration mode.
