Problems solved by technology

However, the existing trading platform has the problem of distrust between the two parties
Due to the information asymmetry between the two parties in the transaction, it is difficult for the user to distinguish the source of the item and the authenticity of the item, and it is impossible to trace the source of the item. The security of the transaction is low, which greatly reduces the transaction efficiency.

Abstract

The embodiment of the invention discloses a transaction processing method and device, equipment and a storage medium. The method comprises the steps of obtaining user information and target article information in response to a transaction initiation request of a user for a target article, wherein the user information comprises a user public key, and the target article information comprises a current owner public key of a target article; generating a transaction contract of the target object according to the user public key, the current owner public key and a blockchain smart contract; determining whether the current owner and the user are target transaction parties of the transaction contract or not according to the current owner and a private key input by the user; and if so, replacing the current owner public key of the target article with the user public key to complete the transaction of the target article. The transaction between two transaction parties on the blockchain is realized, the transaction information is prevented from being tampered at will, and the security of the transaction is ensured.

Description
