Multi-party fair contract deposit method and system based on blockchain technology

Abstract

The present invention relates to a multi-party fair contract storage method based on block chain technology, which uses block chain technology and CA digital certificate system to realize the activation management method of digital data storage technology, and initializes, adds, updates, and Freezing and other management processes are mapped to the form of transaction orders in the blockchain network. The data stored in the certificate is written into the transaction form after being confirmed by the signatures of multiple parties. Into the blockchain global ledger data, forming a non-tamperable, undeniable, no single point of failure management method of deposit data, which solves the common problems of credit single point dependence and single point of failure in the current centralized certificate deposit technology The problem that the original data of the post-deposit certificate cannot be recovered.

Description

technical field [0001] The invention belongs to the technical fields of block chain technology and data storage certificate, and in particular relates to a data storage technology and certificate storage data management technology based on block chain technology. Background technique [0002] Commercial contracts are usually called fair contracts in the field of information technology, and their fairness is reflected in the fact that the content of the contract includes the division of interests and responsibilities of two parties (or multiple parties). Should always be in a position of balance. Today, when business contracts or business interaction information are gradually stored electronically, contracts or documents stored in the form of electronic documents are easy to delete and tamper with. Therefore, ensuring the authenticity and integrity of electronic contracts is a ubiquitous realistic demand , It is necessary to store electronic contracts or related documents in...

Problems solved by technology

[0005] 2. The current data storage technology is based on the one-way hash function and the digital signature technology of the asymmetric secret key to form a "data summary" for the integrity verification of the original data, which is a kind of "cured" data management In this way, management operations such as updating and freezing the stored evidence data cannot be implemented. After the original data is destroyed, the original data cannot be restored through the "Data Summary"
