Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0030] like figure 1 As shown, the present invention provides a practical transaction broadcast solution, which mainly includes a transaction broadcast module. The transaction broadcast module includes functions such as broadcasting transactions, broadcasting transaction hashes, and requesting complete transaction information based on transaction hashes.

[0031] In the alliance chain scenario, the number of consensus nodes is often limited, and the information of consensus nodes can be queried. After...

Abstract

The invention provides a transaction broadcasting method and system, including a validity checking step: after a node receives a transaction sent by a user, it checks the validity of the transaction; a judging step: judging whether the node has the transaction, and if so, then Ignore the transaction; if it does not exist, enter the transaction source determination step; transaction source determination step: determine whether the transaction source is a user or another node, if the determination result is a user, broadcast the complete information of the transaction to other consensus nodes according to the consensus node information ; If the judgment result is other nodes, broadcast the hash of the transaction to other consensus nodes according to the consensus node information. On the premise of ensuring that the complete information of the transaction is quickly spread among the consensus nodes, the present invention makes each consensus node receive the complete information of the transaction only once as much as possible. By broadcasting transactions and transaction hashes in stages, the transmission of repeated transaction information in the network is greatly reduced, and the impact of transaction broadcasting on block consensus is reduced.

Description

technical field [0001] The present invention relates to the field of block chains, in particular to a transaction broadcasting method and system. Background technique [0002] In the case of high concurrency, the occupation of transmission bandwidth by transaction broadcasting will affect the efficiency of block consensus among nodes to a certain extent, thereby reducing the transaction processing efficiency of the entire network. By broadcasting transactions and transaction hashes in stages, the transmission of repeated transaction information in the network can be greatly reduced. The difficulties in the above schemes are: ensuring the rapid dissemination of transaction information between nodes and reducing the spread of repeated transactions in the network. [0003] The patent document CN110443610A discloses a method, system, equipment and storage medium for reducing repeated broadcasting of transaction groups, which belongs to the field of blockchain technology. Inclu...
