Embodiment Construction
[0063] In order to make the object, technical solution and beneficial effects of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0064] For the convenience of understanding, the terms involved in the embodiments of the present invention are explained below.
[0065] The technical field of financial technology (Fintech) usually involves a variety of transactions. For example, bank transactions can include card sales transactions, deposit transactions, loan transactions, insurance transactions, wealth management transactions, etc. The daily transaction volume of banks can reach thousands or even several Thousands of strokes. With the gradual development of blockchain technology, blockchain technology can also be us...

The embodiment of the invention provides a transaction broadcasting method based on a block chain system and a node, and relates to the technical field of financial science and technology. The methodcomprises the following steps that: a first node receives a to-be-agreed transaction, and then determines whether a second node connected with the first node receives the to-be-agreed transaction or not according to a transaction bit vector mapping table, wherein the transaction bit vector mapping table comprises a transaction bit vector sent by the second node, the transaction bit vector is usedfor representing the to-be-agreed transaction received by the second node; and if the to-be-agreed transaction is not received, the to-be-agreed transaction is sent to the second node, and otherwise,the to-be-agreed transaction is not sent. After the first node receives a to-be-agreed transaction, the first node determines a second node which does not receive the to-be-agreed transaction by querying the transaction bit vector mapping table, and the first node sends the to-be-agreed transaction to the second node which does not receive the to-be-agreed transaction instead of sending the to-be-agreed transaction to all second nodes, so that the bandwidth occupation is reduced, and the block chain consensus efficiency is improved.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of financial technology (Fintech), and in particular to a transaction broadcasting method and nodes based on a blockchain system. Background technique [0002] With the development of computer technology, more and more technologies are applied in the financial field. The traditional financial industry is gradually transforming into financial technology (Fintech), and blockchain technology is no exception. However, due to the security and real-time requirements of the financial industry , but also higher requirements for technology. In the blockchain system, in order to ensure the accuracy of transaction execution, nodes are usually required to broadcast transactions to other nodes in the entire network, and use multiple nodes to achieve consensus on blocks. If the number of nodes is large, there will be a large number of repeated transactions in the network. These redundant transaction...
