Problems solved by technology

However, since there is no absolute authority node in this transaction method, it is necessary to collectively verify each transaction
However, the current blockchain transactions cannot verify the user's information during the transaction, and cannot encrypt the transaction information, so there is a risk of information being stolen

Abstract

The invention relates to the technical field of block chains, in particular to a secure transaction method based on a block chain, a client sends a transaction request and a transaction key to a block chain receiving node, and the block chain receiving node sends verified information and the transaction key to each node of the block chain; each node of the block chain compares the transaction key with own predetermined public key information, and when the comparison result is consistent, the corresponding block chain node accepts the transaction request, and transaction is carried out with an account corresponding to the block chain node according to a transaction rule prepared in a contract in the block chain; when the client side transacts, the client side IP address, the user name and the login password corresponding to the client side are verified, the transaction is carried out after the transaction secret key is compared with the public key information, other irrelevant parties cannot attack maliciously, the account safety is effectively guaranteed, and the transaction processing efficiency can be improved.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a secure transaction method based on block chains. Background technique [0002] Blockchain technology has the characteristics of decentralization and non-tamperable information. Using blockchain technology can realize transaction events involving multiple parties (for example, transfer transactions, payment transactions, etc.). If the transaction is performed on the blockchain, all other nodes on the blockchain will know the transaction, and other participants can participate in confirming the accuracy of the transaction to prevent information tampering. However, since there is no absolute authority node in this transaction method, collective verification of each transaction is necessary. However, the current blockchain transactions cannot verify the user's information during the transaction, and cannot encrypt the transaction information, so there is a risk of inf...
