Fig. 1 is a flowchart of a storage method of a public trust file according to an embodiment of the present invention, and as shown in fig. 1, the method is applied to a block chain, where the block chain includes a plurality of node clusters, where each node cluster includes a plurality of node cluster administrators and a plurality of node administrators, each node cluster administrator is used to manage the plurality of node administrators, and each node administrator is used to manage a plurality of nodes, and includes the following steps:
step S102, after a public letter file uploaded by a user is obtained, a target node group administrator of a target node group sends a synchronization request to nodes in the target node group, wherein the synchronization request carries the data volume of the public letter file, the target node group is a node group where the user is located, and the target node group administrator is a node group administrator with the highest connection speed between the user and the plurality of node group administrators of the target node group;

step S106, after the target node sends the file synchronization certificate to other nodes and the other nodes finish verification of the file synchronization certificate, the target node is used for storing the public trust file and obtaining a reward based on the file synchronization certificate, wherein the reward comprises: and storing space and/or virtual currency, wherein the other nodes are nodes in the target node group except the target node.
In the embodiment of the present invention, after obtaining a public affair file uploaded by a user, a block chain sends a synchronization request to a node in a target node group through a target node group administrator of the target node group, where the synchronization request carries a data volume of the public affair file, the target node group is a node group where the user is located, and the target node group administrator is a node group administrator with the highest connection speed between the user and one of a plurality of node group administrators of the target node group; after a target node administrator acquires feedback information sent by a target node based on the synchronization request, the target node administrator sends a file synchronization certificate to the target node, wherein the target node is a node with a storage space larger than the data volume of the public information file in the target node group, and the target node administrator is a node administrator managing the target node; after the target node sends the file synchronization certificate to other nodes and the other nodes finish verification on the file synchronization certificate, the target node is used for storing the public trust file and obtaining a reward based on the file synchronization certificate, wherein the reward comprises: and the other nodes are nodes except the target node in the target node group, so that the aim of storing the public letter file by using a block chain technology is fulfilled, the technical problem of poor storage safety of the public letter file in the prior art is solved, and the technical effect of the storage safety of the public letter file is realized.
After the user joins the target node group, the nearest miner manager (i.e., the target node manager) is found, then the miner manager is informed that a public trust file needs to be stored, and then the miner manager sends a synchronization request to the nodes in the target node group.
Then, after the node (i.e., the target node) with enough storage space for storing the official document receives the synchronization request, the target node sends feedback information for applying to acquire the document synchronization certificate to the corresponding miner (the target node administrator).
Then, a target node administrator issues a file synchronization certificate to a target node, the target node sends the file synchronization certificate to other nodes in the node group after acquiring the file synchronization certificate, the target node acquires and stores the public letter file after determining the file synchronization certificate by other nodes in the node group, and the target node administrator corresponding to the target node issues rewards for the target node after the storage is completed.
It should be noted that the specific value of the storage space and/or virtual currency in the reward may be carried in the file synchronization voucher.
In the embodiment of the invention, the storage safety of the public letter file can be effectively improved by storing the public letter file through the block chain, and further, by issuing the reward for the node for storing the public letter file, more nodes can be prompted to store the public letter file, and the storage safety of the public letter file is further improved.

In the embodiment of the invention, firstly, the IP addresses of a plurality of node group administrators are determined.
Then, determining the connection speed between the IP addresses of the node group managers and the IP address of the user according to the IP addresses of the node group managers;
and finally, determining the node administrator corresponding to the IP address with the highest connection speed between the IP addresses of the plurality of node group administrators and the IP address of the user as the target node group administrator.
The embodiment of the invention realizes a distributed official document storage scheme by using decentralized block chain. Each stored node stores complete data according to a block chain structure, and the storage of each node is independent and equal in status, and the consistency of the storage is ensured by means of a consensus mechanism. No one node can record the stored data separately, thereby avoiding the possibility that a single trust file is controlled or modified by bribery. And the storage nodes are enough, so that the official document can not be lost unless all the nodes are damaged theoretically, and the data security is ensured. Anyone joins and synchronizes, and the nodes become block chain storage nodes; each node group is synchronized by a miner management data, and the miner groups form the whole block chain structure.
Furthermore, by utilizing the decentralized of the block chain, a distributed public letter file storage scheme is realized, the scheme can utilize the storage safety characteristic of the block chain to the maximum extent, and the technical breakthrough is realized in the aspects of tamper resistance and loss resistance of the safe storage of the public letter files; since the joining node group will receive the rewarded token (virtual currency), more and more people will join the storage node to achieve the goal of decentralization, security, tamper-proofing, and stable storage of the public letter file.
