Problems solved by technology

[0005] Again, the system reliability is poor
The value transfer between banks relies on intermediary nodes of mutual trust to form a trust chain. If any node fails, it will lead to the re-establishment of transaction routing, and even make the transaction impossible
The extension of the transaction path increases the hidden dangers of failures and risks, and the business system has to build a backup system for transaction endorsement, w

Abstract

The invention provides a block-chain-based financial product transaction consensus method, node and system. The method comprises: a first verification node receives a transaction consensus applicationsent by a transaction node and decrypts the transaction consensus application to obtain transaction information; the transaction certificate is verified by using a transaction certificate preset in the first verification node to determine whether transaction is legal or not; if so, the transaction information is logically verified by using a smart contract preset in the first verification node and whether the transaction logic is legal is determined; if so, the smart contract corresponding to the transaction information is executed, the transaction information is broadcasted to all second verification nodes in a built-in verification node list of the first verification node and a transaction consensus decision is initiated; voting information fed back by the second verification nodes within a preset verification cycle is received and whether the proportion of the consensus of the voting information exceeds a preset threshold is determined; and if so, a transaction consensus message issent to the transaction node.

Description

technical field [0001] The present invention relates to a banking financial product transaction system and method, in particular to a blockchain-based financial product transaction consensus method, node and system. Background technique [0002] With the development of financial business, especially the rise of Internet finance, traditional banks, financial institutions, third-party payment institutions, and emerging Internet financial companies are becoming more and more closely connected. More and more; the delivery of financial assets has also extended from transfers and remittances in the traditional sense to financial asset transactions such as account precious metals, futures, and bills of exchange.
