Problems solved by technology

In addition, there have been frequent security incidents in the blockchain industry in recent years. Experts and scholars in the industry generally believe that there is still a long way to go before the large-scale implementation of blockchain applications on the premise that security is not fully guaranteed.
But while these studies point to problems and concerns, they do not suggest a viable alternative model and solution

Abstract

The invention discloses a weakly centralized trusted data storage system and management method with separation of writing and verification. The system includes a central storage module and a client storage module. The central storage module includes a central database and a block chain. The central database For storing complete data records, the block chain is used for storing data fingerprints corresponding to complete data records; the client storage module includes a local database and a block header hash chain, and the local database is used for storing data fingerprint hash values The copy fragment of the block header hash chain is a data chain composed of all the block headers. Centralized data storage combined with distributed, light-client data verification combines the efficiency and convenience of the centralized model with the security and transparency of the decentralized model.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a weakly centralized trusted data management method and system. Background technique [0002] In traditional data application systems, whether it is a single-center system or a distributed system in form, the data management authority is controlled in a single entity. In terms of the management subject, it is essentially a centralized storage scheme (Centralized Storage Scheme, CSS), that is, The storage, maintenance and query of data are all implemented by the center, and the consistency between all data copies is also coordinated by the center. The advantage of this model is the high efficiency of data management, but the stored data is a "black box" to the outside world, lacking transparency and supervision. Customers can only accept it passively, and it is difficult to guarantee the authenticity and correctness of the data. Social trust is essentially a kind of public cognitio...
