Abstract

The invention discloses a file management method and device based on a block chain and a medium. The method comprises steps of a hash value of a file being determined; writing the hash value of the file into a blockchain, and storing the file and the hash value corresponding to the file into a storage device of a node of the blockchain; receiving a request of a user for acquiring the file, and determining a node for storing the file according to the hash value of the file; and opening a communication interface of a node for storing the file to the user so that the user acquires the file through the node and verifies the file through the hash value in the blockchain; generating a hash value corresponding to the file according to the content of the file, storing the hash value on a block chain, storing the file on a plurality of nodes, and searching and downloading the file by taking the hash value as a medium. The method is advantaged in that the uplink data only has a hash value, so resources are greatly saved.

Description

Technical field [0001] This application relates to the field of blockchain technology, and in particular to a file management method, equipment, and medium based on blockchain. Background technique [0002] In the past few decades, the wave of informatization and digitization has swept the world. Mobile Internet has turned almost all businesses into online businesses. Mobile Internet has also removed the regional nature of businesses. The number of users of many systems ranges from hundreds of thousands of users. Become tens of millions or even hundreds of millions of users worldwide. [0003] Today, there are thousands of large data centers in the world, and information is stored in these large data centers. This means that the servers that store the data are controlled by one company. If there is a problem with the server storing these data, it will affect the data acquisition, and in serious cases, the data cannot be restored. Summary of the invention [0004] The embodiments ...
