Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a blockchain-based method and device for sending and depositing certificates for electronic letters. Background technique [0002] Today, with the advancement of science and technology and the increasing economic development, the existing electronic evidence storage and verification systems mostly use centralized database systems to store electronic evidence sets, and then present the relevant information of the electronic evidence sets in the form of files. If the evidence set is consistent with the electronic evidence set in the centralized database system, it is determined that the electronic evidence set has not been tampered with and can be adopted. Traditional data storage and identification have the following disadvantages: [0003] 1. It is all carried out by a third-party organization, which leads to the owner of electronic data needing to trust the organizati...

Problems solved by technology

[0003] 1. It is all carried out by a third-party organization, which leads to the owner of electronic data needing to trust the organization unreservedly. Once the third-party organization maliciously tampers with the deposit certificate and issues false identification information, it will cause another user huge loss

[0004] 2. The files will be completely saved on the server, which is a challenge for server storage and increases the risk of data leakage
