First embodiment
Referring to fig. 2, fig. 2 is a flowchart illustrating a storage sharing method according to a first embodiment of the present invention, where the method is applied to a blockchain distributed network topology. The flow shown in fig. 2 will be described in detail below, and the method includes:
step S110: when a data storage request initiated by a client is obtained, the data storage request is recorded to an account book and stored in each full node.
When an individual or enterprise holds idle resources, the idle resources can be uploaded to the blockchain distributed network topology through a client to be stored. Optionally, the client may generate a data storage request in response to a data storage instruction of a user, and send the data storage request to the blockchain distributed network topology.
After the block chain distributed network topology acquires the data storage request, the request can be recorded into an account book, and the account book is synchronized to all the nodes for storage. The ledger is aggregated from all the transactions in the block and is used for storing a table of data.
Step S120: and determining a plurality of target storage nodes from the at least one storage node, and sending the information of the target storage nodes to the client.
Wherein the information of the target storage node comprises an address of the target storage node.
Step S130: and acquiring the resources to be stored sent by the client, and storing the fragmented resources to be stored in the target storage nodes in a manner that each target storage node stores a piece of sub-resource after the resources to be stored are fragmented.
After receiving the information of the target storage nodes, the client may upload the resource to be stored to each target storage node of the block chain distributed network topology for storage.
Optionally, the block chain distributed network topology may first segment the resource to be stored to form multiple sub-resources, and then store each sub-resource in one target storage node, so that one target storage node stores one sub-resource or multiple sub-resources.
The block chain distributed network topology may divide the resource to be stored into multiple sub-resources according to a pre-stored fragmentation threshold (for example, 8MB or 32MB), where the length of each sub-resource is equal to the fragmentation threshold, and when the length of a certain sub-resource is less than the fragmentation threshold, 0 may be used for padding.
Of course, optionally, in order to ensure the security of the data, the client may encrypt the resource to be stored and then send the encrypted resource to the blockchain distributed network topology. The encryption method is determined according to the actual situation of the client user.
Step S140: and backing up the resources to be stored to other storage nodes based on a pre-saved security policy.
The security policy defines the number of resources to be stored that need to be backed up. The backup operation is performed to ensure the security and availability of the resources to be stored.
Assuming that there are b target storage nodes in the block chain distributed network topology, the resource to be stored is fragmented into p parts, and the backup part of each data fragment is n. The probability Rs of successful data retrieval is given by:
of course, the block chain distributed network topology may further include an observation node, configured to monitor whether the number of current backup data reaches a value defined by the security policy, and if not, continue to issue the backup task until the number of backup data in the remaining storage nodes reaches the value defined by the security policy.
Step S150: and updating the storage node information for storing and backing up the resources to be stored and the state information of the resources to be stored to the account book.
The state information of the resource to be stored comprises: and if the resources to be stored are stored, storing a plurality of parts and distributing the parts at which nodes. And updating the storage node information for storing and backing up the resources to be stored and the state information of the resources to be stored to the account book so that a subsequent client can retrieve data based on the account book.
As an alternative implementation, referring to fig. 3, after step S150, the method may further include:
step S160: when a data retrieval request initiated by the client is obtained, the data retrieval request is recorded to the ledger and stored in each full node.
Step S170: and after the client is determined to retrieve the resource to be stored, updating the state of the resource to be stored.
As an optional implementation manner, before determining that the client retrieves the resource to be stored, the method further includes:
and pushing the storage node information for storing and backing up the resources to be stored to the client so that the client actively establishes contact with the storage node for storing and backing up the resources to be stored to retrieve the resources to be stored.
As another optional implementation, synchronizing the data retrieval request to a storage node storing and backing up the resource to be stored;
and the storage node for storing and backing up the resources to be stored passively pushes the resources to be stored to the client.
Of course, optionally, the client may also pay the reward after uploading the resource to be stored. After the client retrieves the resource to be stored, the client may also send a proof book to the blockchain distributed network topology to prove that the target storage node actually stores the resource to be stored.
After obtaining the certificate ledger sent by the client, the distributed network topology may issue rewards to the target storage nodes based on the certificate ledger.
Optionally, a check code randomly generated by the client or the observation node over time is stored in the certification account book, and based on the certification account book, awards are issued to the target storage nodes, where the method includes:
and sending the check code to the target storage nodes, so that the target storage nodes generate a check tree based on the check code. And the target storage node sends the check tree to the client or any one observation node for verification within preset time. When the check code is judged to be consistent with the generation path of the check tree, the representation verification is successful, and rewards can be issued to the target storage nodes.
Optionally, the observation node may further continuously adjust backup and distribution of resources to be stored, so as to ensure that the current data file is secure and has at least one accessible resource. An observation node may require other storage nodes to save a copy of the data if a storage node is unavailable. Sometimes, the old node is only temporarily disconnected from the network or is accidentally down, and when the old node is reconnected to the network, the problem arises that which node should continue to store the data backup and obtain the reward. For this case, the blockchain distributed network topology is determined according to the credit level of the node. In principle, a storage node with a high credit rating will continue to store data and receive a storage reward, and a low credit rating will require deletion of data.
The credit grade is calculated according to the total storage amount, the storage duration, the online duration, the punished amount, the maximum transaction processing amount, the block outlet degree, the bifurcation convergence degree, the online duration and the like of the current node.

the block chain distributed network topology further comprises at least one observation node, the certification account book stores a check code generated by the client, and the update module is further configured to send the check code to the target storage nodes, so that the target storage nodes generate a check tree based on the check code; sending the check tree to the client for verification within preset time, and acquiring verification information fed back by each client, or sending the check tree to any one observation node for verification within preset time, and acquiring verification information fed back by the observation node; issuing a reward to the plurality of target storage nodes upon determining that the verification information characterizes a verification pass.
7. A blockchain distributed network topology comprising at least one storage node and at least one full node, the storage node and the full node comprising a memory, a processor, a computer program stored in the memory, the computer program when executed by the processor causing the blockchain distributed network topology to perform the method of any of claims 1-5.
