Digital certificate system based on block chain technology

Abstract

The invention provides a digital certificate system based on a block chain technology. The digital certificate system comprises a personal digital certificate packet module, a certificate utilization department certificate packet module, a digital certificate block chain account book, and a digital certificate distribution type storage node. The digital certificate block chain account book comprises blocks, which are used to form a block chain according to a time sequence logically, and a tamper-proof block chain account book is formed, and every block is used to store certificate transaction, and mainly comprises certificate text description information and a certificate code. The digital certificate distribution type storage node comprises nodes, which are constituted by certificate issuing departments and the certificate utilization departments, and are used to store the digital certificate block chain account books and the complete original information of the certificates. According to the digital certificate system based on the block chain technology, a potential systematic risk of storage of a single centralized mechanism is prevented, and the digital certificate information is safe and credible; the certificates are maintained by various departments, and system construction and maintenance costs are reduced; the credible transfer of the certificates the departments during the use of the certificates is realized, and cooperated working among the departments is facilitated.

Description

technical field [0001] The invention relates to the field of digital certificates, in particular to a digital certificate system based on block chain technology. Background technique [0002] At present, certificates are stored and managed by a single centralized system of the issuing department. The certificate issuing unit, the certificate user, and the certificate holder are both independent and interrelated. When the system is breached, it is easy to cause problems such as information tampering and privacy leakage, and the centralized organization may even tamper with information by internal personnel. Certificates exist in the form of paper, and each person will have hundreds of certificates in his life, which is difficult to store and manage. At the same time, the certificate-using unit needs to review a large number of paper certificates, which is inefficient. The certificates produced by the existing technology cannot guarantee the authenticity of the certificates, ...

Problems solved by technology

[0006] However, there are many types of license transactions, such as real estate certificates, mortgages, transfers, etc., and the relationship between transactions is more complicated, and the verification of license transactions is also more complicated; there are many license states, and it is more difficult to maintain consistency in a distributed system; In terms of storage, certificates need to store complete original information, while currencies only need to store a value. The transaction of certificates has higher requirements on network pressure, throughput, and communication volume
