Problems solved by technology

However, since there is no absolute authority node in the decentralized blockchain system, collective verification of each transaction is a necessary step, which makes the transactions of the transaction participants no secret at all, and an organization's account also May be tracked by institutions on other nodes, which brings the risk of infor

Abstract

The invention discloses a transaction verification method and system based on a block chain. The method comprises the following steps: when a node on the block chain processes a transaction with a transaction type and a transaction amount, decrypting an original balance of each transaction side through first decryption parameters sent through the transaction sides, obtaining new balances by calculating each original balance, obtaining encrypted new balances by encrypting the new balances through encryption parameters sent by the transaction sides, and broadcasting each encrypted new balance on each node of the block chain; when the node of the block chain receives the broadcast encrypted new balance of each transaction side, starting an intelligent contract to perform composite number verification; if the composite number verification succeeds, performing updating based on each corresponding encrypted new balance; and invoking an external negative balance verification system to perform negative balance examination on each account balance, and if the negative balance examination succeeds, determining that transaction verification succeeds. According to the invention, whether the transaction is normal can be verified, and the transaction processing speed on the block chain can also be guaranteed under the condition that the system overhead is not occupied.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a transaction verification method and system based on block chains. Background technique [0002] Due to its decentralization and non-tamperable information, blockchain technology is increasingly favored by companies in the fields of finance and insurance, especially the use of blockchain technology to achieve multi-party transactions (for example, transfer Transactions, payment transactions, etc.) are increasingly becoming the focus of attention. For example, when bank A wants to buy 100 bills to bank B, if the transaction is carried out on the blockchain, then all other nodes on the blockchain will The advantage of seeing this transaction is that other participants can participate in confirming the accuracy of the transaction and preventing information tampering. However, since there is no absolute authority node in the decentralized blockchain system, collective ...
