Cross-border electronic signature method based on block chain and readable storage medium

Abstract

The invention discloses a cross-border electronic signature method based on a block chain and a readable storage medium. The method comprises the steps that an electronic signature is formed after anencryption key is agreed with a second node user, the signature and the agreed encryption key are embedded into a character string to be signed and then broadcasted into a block chain, and the secondnode user obtains the character string from the block chain and then decrypts the character string through the agreed encryption key, wherein the character string can be subjected to secondary encryption operation so as to ensure the safety of information, and can also be downloaded and stored in a readable medium so as to be conveniently used in an off-chain manner. The electronic signature method further comprises a language translation system and a time compilation system. And an intra-region block chain can be constructed in each administrative region to accept supervision and authentication of the respective administrative region, so that the requirements on languages, time differences and different policies and adjustments of different administrative regions in cross-border servicesare better met, the safety of cross-border transactions or services is ensured, and the response time and efficiency of transactions or services are improved.

Description

Technical field [0001] The present invention relates to the technical field of block chains, in particular to a cross-border electronic signature method based on block chains and a readable storage medium. Background technique [0002] In recent years, with the popularization and development of the Internet, various electronic service platforms have continuously emerged and have been developed by leaps and bounds, which has promoted the economic take-off and brought great convenience to the people. With the encouragement of relevant national policies And promotion, cross-border electronic services have developed rapidly. [0003] However, the following problems exist in the implementation of traditional technology: [0004] (1) Due to the many links involved and the complicated and cumbersome procedures, there are loopholes in the process. Once the potential risk occurs, it will bring huge losses to the participating users, and the international disputes are very troublesome to reco...
