Background
Trusted file storage is a novel architecture in the current internet system, and the traditional file storage system cannot guarantee the file storage to be trusted.
Conventional file storage systems store files on servers of an enterprise, and the files may be modified without being discovered, and the credibility of the files cannot be guaranteed. Files can be stored in the block chain by using the block chain, so that the credibility of the files can be ensured, but the block size of the block chain is limited, and the low performance of the block chain can be caused by storing large files.
In order to solve the problem that the performance is low due to the fact that a blockchain stores large files, the blockchain does not store the large files, but stores the large files under the chain and only stores unique file identification and file description information. By adopting the micro-service architecture, the functions required by the system can be separated, each service is concentrated on the functions required to be provided, the development difficulty is reduced, the development efficiency is improved, the system stability is enhanced, and reasonable distribution is performed according to the difference of the resources required by each service.
Based on the micro-service architecture, the block chain and the file storage technology, the expansibility of the micro-service architecture and the credibility of the block chain technology can be exerted, and an extensible credible file storage system is created. Data credibility cannot be guaranteed only by using the microservice architecture, and efficient storage cannot be expanded only by using the block chain.

(1) the blockchain using service unit receives the file hash, the file description information and the signature of the user on the file hash and the file description information which need to be recorded in the blockchain;
(2) the block chain uses the service unit to check whether the signature belongs to the correct user; if not, the upload is terminated.
(3) The block chain uses the service unit to access the intelligent contract on the block chain, and uploads the file hash, the description information of the file and the user address to the block chain;
(4) and the block chain records the file hash, the file description information and the user address uploaded by the user.
Further, in the step (2), the blockchain uses the service unit to verify the signature by using an SM2 elliptic curve public key cryptography algorithm.
The invention has the following beneficial effects:
the trusted file storage system based on the micro-service architecture fully combines the credibility of the block chain, the expansibility of the micro-service architecture and the high efficiency of the traditional storage system, and improves the storage efficiency of trusted files. The file is stored on a storage system and generates a unique hash. Due to the adoption of the micro-service architecture, the expansion can be conveniently carried out, and the system performance is improved. Finally, the system stores the unique hash of the corresponding file and the file description information on the blockchain. The system greatly improves the file storage efficiency while meeting the credibility, and provides a solid foundation for credibly storing a large number of files.
