Kind Code:
A1
Abstract:
A file sharing method, apparatus, and system, mainly relating to the technical field of computers. The method comprises: obtaining a file to be shared; executing a blockchain concurrent on-chain operation on shared file compression packages; forming data blocks according to a compressed package file name and a hash value thereof, wherein the data blocks comprise the hash value of a previous data block; using the hash value of a last data block as a root hash value; and according to the root hash value, obtaining a file comprised in the last data block, and then obtaining each file compression package in a blockchain indicated by the root hash value. By compressing a plurality of files into file packages, the present application partially overcomes the technical problem that the burden of a network resource is too high due to a large number of files; the file on-chain and sharing efficiency is improved by performing concurrent on-chain on each file compression package; and a one-way linked list data structure on the blockchain is used to save and share the file, thereby improving the security of the file.
