Digital asset information exchange system and method based on block chain

Abstract

The invention belongs to the technical field of block chains and internet information, and discloses a digital asset information exchange system and method based on a block chain. The digital asset information exchange system based on a block chain comprises a data provider module, a data consumer module, a block chain network module, and a smart contract module. The digital asset information exchange system provides a preset digital asset exchange mode based on the intelligent contract technology of the block chain, does not need to consider the trust problem between subjects, aiming at the problems that a traditional data exchange mechanism depends on a third-party payment mechanism, and data records are prone to being tampered and forged. Based on an exchange medium of the block chain cryptocurrency, multiple subjects jointly maintain an account book, so as to guarantee that records are real, reliable and not tampered. According to the digital asset exchange mechanism disclosed by the invention, the digital asset exchange mechanism is developed on the basis of the characteristics of confidentiality, integrity, non-repudiation and the like of the block chain, and data asset exchange and sharing are promoted.

Description

technical field [0001] The invention belongs to the field of blockchain technology and Internet information technology, and in particular relates to a blockchain-based digital asset information exchange system and method. Background technique [0002] At present, the closest existing technology: Under the influence of emerging technologies such as the Internet of Things and cloud computing, data is growing explosively at an alarming rate, and massive data marks the arrival of the era of big data. How to deal with the relationship between sharing, openness and security in the "big data dictionary" is a question worthy of our consideration in the era of shared and open big data, and it is also the only way to promote the era of real big data. [0003] In order to realize the era of real big data sharing, how to share data safely and securely is a major issue worth considering. The existing data exchange architecture centers are all centralized and centralized. In this way, d...

AI Technical Summary

Problems solved by technology

[0007] (1) The traditional data exchange system generally adopts a centralized architecture, and the server centralized deployment method has problems such as single point of failure, low reliability, and network congestion.

[0008] (2) In the traditional data exchange mechanism, there are trust problems among the transaction subjects. The transaction model often requires a lot of financial resources and time. In addition, there are also trust problems in the centralized structure

[0009] (3) Since traditional data exchange mechanisms rely on third-party payment institutions, data records are vulnerable to tampering and forgery

[0011] At present, the mainstream applications and systems are all centralized architecture models, relying on the central server to process transactions, and the log system is recorded on the central server. This model has matured and changed from a centralized architecture model to a decentralized one. The architecture is difficult, and the consensus between distributed servers also needs to overcome the difficulty of the consensus mechanism; it is difficult to achieve trust among the parties, and the central server cannot satisfy complete credibility; currently there is no third-party payment institution Other point systems can be directly bound to value, and there are certain difficulties in replacing third-party payment institutions
