Electronic contract block chain structure and electronic contract signing device and method

Abstract

The invention provides an electronic contract block chain structure and an electronic contract signing device and method, and belongs to the technical field of electronic contracts. An electronic contract signing application system and an electronic contract block chain are included. The electronic contract signing application system comprises a user login authentication module, a secret key management module, an electronic signature module, a data encryption and decryption module, a contract auditing module, a contract chaining module, a contract signing module and a data acquisition module.The electronic contract block chain comprises an interface service module, a transaction construction module, an intelligent contract module, a state control engine, a block chain transaction accountbook and a large file storage engine. Trusted trusteeship is provided for the electronic contract through the block chain technology, and it is guaranteed that big file data of the electronic contractis safely stored and cannot be tampered; the signing process of the electronic contract is truly and credibly recorded based on the block chain, the whole process is traceable, the signing state of the electronic contract is intelligently changed in real time, and the credibility of the signing state is guaranteed.

Description

technical field [0001] The present disclosure relates to the technical field of electronic contracts, in particular to an electronic contract block chain structure, an electronic contract signing device and method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] Most of the current signing methods use paper contracts, in the form of signing, stamping or fingerprinting. However, with the development of modernization and the continuous enrichment of business forms, the process of signing paper contracts is cumbersome, time-consuming and labor-intensive, and contracts will be lost later. , The risk of damage, can no longer meet the requirements of the existing contract signing. With the development of Internet technology and the improvement of corresponding laws and regulations, electronic contracts have begun to be widely used. The tradi...

Problems solved by technology

[0005] The inventors of the present disclosure found that most alliance chain platforms in the industry currently do not support the storage of large files or large file data of limited size on the chain, and require the application layer to store large file data, and only the digital summary of large file data is stored in the blockchain value, disaster recovery management, high availability, encryption and decryption, and correctness verification of large files need to be implemented at the application layer, and the security of large file data is difficult to guarantee; for supervision, all participants in the public chain are anonymous, so it is difficult to Supervise the trading activities of each participant. The alliance chain or private chain is allowed to enter. By verifying the identity information of the participants, it provides convenience for supervision, but the degree of openness to the regulator is low, and effective security supervision cannot be achieved.
