Abstract

The invention provides an online contract signing system and an online contract signing method on the basis of block chain technologies. The online contract signing method includes allowing contract initiators to log in systems; creating electronic contracts; carrying out encrypting and distributing, to be more specific, encrypting the electronic contracts by network engines of clients and then distributing the electronic contracts to clients of various contract signatories; decrypting contract contents by the related contract signatories and viewing the contract contents; selecting signing modes; carrying out encrypting and distributing; storing encrypted contract secret keys by non-contract-signing related parties so that anonymous encrypted unidentifiable contract data on networks can be synchronized after each client logs in the systems. The online contract signing system and the online contract signing method have the advantages that decentralization strategies are completely adopted, all operation is locally carried out, and accordingly the possibility that data leak to third parties can be prevented; anonymous encryption strategies are adopted for contract data, accordingly,encrypted data contents cannot be identified by clients of the non-contract-signing related parties, all global clients need to be tampered by optional protocol tampering operation, no optional client has the permission for operating data of the other clients, and the tampering possibility can be completely eradicated.

Description

technical field [0001] The present invention is developed based on blockchain technology and can be applied to the technical field of online signing of various types of contracts, and specifically relates to an online contract signing system and method based on blockchain technology. Background technique [0002] In order to solve the office cost, logistics transportation cost, and time cost brought about by paper contract signing, electronic contract technology has developed a large number of electronic contract signing platforms under the premise of rapid development of computer technology. [0003] Article 11 of the "Contract Law", which was implemented by the state on October 1, 1999, stipulates that "written forms refer to forms such as contracts, letters, and data messages that can tangibly express the contents contained in them." This is the first time that Chinese law stipulates that data messages can be used as a written form to sign a contract. [0004] On August ...
