Embodiment 1: The purpose of this embodiment is to provide a resource processing method based on blockchain.

Figure 2 is a schematic diagram of the execution process of this implementation. After the user stores the data resources in the blockchain, he can execute the resource processing method of this embodiment and obtain the data stored in the blockchain by sending a request to the blockchain server. Data resources in the blockchain.

User data resources stored in the blockchain also include user identification ID and encrypted text. When users store data resources in the blockchain, they also construct independent storage records based on the storage address of the data resources in the blockchain, as well as the user identification ID and encryption text in the data resources, and store the storage records in the blockchain. in the server.

As shown in Figure 1, the resource processing method includes:

S1. The blockchain server calls the corresponding data resources in the blockchain according to the resource acquisition authorization instruction sent by the user.

When a user needs to obtain data resources stored in the blockchain, he or she inputs or generates a resource authorization instruction in the client or user terminal, and the authorization instruction is sent to the blockchain server. The authorization instruction contains the user identification ID and verification key.

When the blockchain server receives the resource authorization instruction, it parses the user identification ID and verification key from the authorization instruction. Then all the data resources stored in the blockchain by the user are searched based on the user identification ID, and the corresponding data resources in the blockchain are verified and called based on the verification key.

Specifically, the blockchain server constructs a unified addressing pointer based on the user identification ID, uses the addressing pointer to find the storage record corresponding to the user identification ID in the blockchain server, and searches all the user's stored data in the blockchain based on the storage record. Data resources are pre-called. Then the blockchain server decrypts the verification key to obtain the key plaintext, decrypts the ciphertext in the pre-called data resource based on the key plaintext, and determines the matching data resource by verifying the ciphertext. The matching data resource is the data resource requested by the user this time, and the data resource is finally called.

Further, when the client or user terminal on the user side sends the authorization instruction, it initially decrypts the verification key in the authorization instruction, and the blockchain server performs a secondary decryption of the preliminary decryption verification key to obtain The final key plaintext.

S2. The blockchain server displays the preview information of the called data resource to the user, and the user confirms whether it is the requested data resource.

After calling the corresponding data resource, the blockchain server obtains the basic information of the data resource. The basic information includes the storage location of the data resource and the content summary of the data resource. Then the preview information of the data resource is generated based on the basic information, and the preview information is displayed to the user.

The user confirms whether the data resource is the requested data resource based on the preview information. If not, the user feedbacks "Preview Resource Error" to the blockchain server, and the blockchain server aborts this task and waits for the user to resubmit to obtain the resource. Execute again after authorizing the command. If so, the user feedbacks "the preview resource is correct" to the blockchain server, and the blockchain server continues to perform subsequent steps.

Furthermore, when the blockchain server displays the preview information, it also displays the authorization instruction sent by the user this time and the verification key in the authorization instruction. The user or the client or user terminal used by the user can follow the authorization instruction. and verification key to determine whether the communication content between it and the blockchain server has been tampered with to ensure information security.

S3. The blockchain server obtains the currently available blockchain computing resources based on the user identification ID in the authorization instruction.

The blockchain server obtains the corresponding resource usage rights based on the current user's identification ID, obtains the corresponding computing resources in the callable blockchain node through the resource usage rights, and then counts all computing resources, and finally obtains the currently available of blockchain computing resources.

S4. Use the obtained blockchain computing resources to calculate the called data resources, and return the calculated and processed data resources to the user.

The blockchain server uses the obtained blockchain computing resources to calculate the called data resources, and returns the calculated and processed data resources to the client or user terminal that sent the resource acquisition authorization instruction.

Furthermore, the resource acquisition authorization instruction sent by the user also contains a third-party address, and the blockchain server can also transmit the processed data resources to the third-party address.

S5: Store the entire process of processing data resources.

The blockchain server generates record data based on the entire process of processing data resources and the final destination of the data resources, and stores the record data in the called block link point and blockchain server to form redundancy storage. The entire process of data resource processing in recorded data includes the request, call, verification, calculation processing, and sending process of data resources.

Furthermore, the usage records generated by the blockchain server also include flow traces of the corresponding data resources.

Further, the processing unit 201 is also used to generate record data including the entire process of data resource processing and transmission destination, and to simultaneously store the record data in the blockchain node and the blockchain server.

The blockchain unit 202 is used to call the corresponding data resources in the blockchain based on the user identification ID and verification key, to obtain the currently available blockchain computing resources based on the user identification ID, and to utilize the blockchain computing resources. Perform calculation processing on the called data resources.

Further, the blockchain unit 202 is also used to search for all data resources stored in the blockchain by the user according to the user identification ID, to construct a unified addressing pointer through the user identification ID, and to find the corresponding address pointer according to the addressing pointer. Storage records are used to pre-call the corresponding data resources in the blockchain based on the storage records.

Further, the blockchain unit 202 is also used to verify and call the corresponding data resources in the blockchain according to the verification key, to obtain the key plaintext after decrypting the verification key, and to use the key plaintext to verify the pre-called data. The encrypted text in the resource is decrypted to determine the matching data resource, which is used to call the matching data resource from the blockchain.
