Decentralized electronic contract attestation platform

Abstract

This application provides a decentralized electronic contract attestation platform, where the attestation platform is connected to a user client through a deposit thread and a forensic thread that are established with an existing electronic contract platform; the attestation platform includes a deposit unit and a forensic unit; the deposit unit is configured to verify transaction data of a deposit transaction initiated by the user client, and if the verification is passed, upload and store the transaction data on a chain; and the forensic unit is configured to obtain, based on a forensic request sent by the user client, transaction data that corresponds to the forensic request and is stored in a blockchain, and send the transaction data to the user client. According to this application, deposit and forensic operations of an electronic contract are correspondingly completed by using the established deposit thread and forensic thread. Managing the transaction data of a user by using the decentralized electronic contract attestation platform avoids a possibility that an existing platform may arbitrarily tamper with the transaction data of the deposit transaction of the user, and improves security of transaction information of the user.
