It should be noted that the structure shown in FIG. 1 is only an example, which is not limited in the embodiment of the present invention.

Based on the foregoing description, FIG. 2 exemplarily shows the flow of an electronic credential uploading method provided by an embodiment of the present invention, and the flow can be executed by an electronic credential uploading device. The process of uploading the electronic credential will be described below through the interaction between the front terminal and the blockchain node.

As shown in Figure 2, the process specifically includes:

Step 201: The front-end terminal obtains an electronic certificate, performs hash processing on the electronic certificate, and determines the hash value of the electronic certificate.

Before step 201, the front-end terminal needs to be registered on the blockchain network platform first, that is, the merchant number, terminal number and public key of the front-end terminal are registered on the blockchain network platform.

Then, the front-end terminal generates electronic vouchers. In the embodiment of the present invention, the electronic vouchers can be electronic purchase orders, electronic invoices, electronic waybills, etc. There is no restriction on this, and all electronic documents can be used as electronic vouchers in the present invention. In the embodiment.

After the front-end terminal generates the electronic voucher, the communication module can be called to send the electronic voucher to the back-end system for storage.

Then call the upload pre-processing module to hash the electronic certificate, and obtain the hash value of the electronic certificate, that is, the hash value of the electronic screen.

Step 202: The front-end terminal determines the signature information according to the front-end terminal's private key, merchant number, terminal number and the hash value of the electronic certificate.

After the blockchain node receives the hash value of the electronic certificate sent by the front terminal, the merchant number and terminal number of the front terminal, and the signature information, it can determine the front terminal according to the merchant number and terminal number of the front terminal 'S public key. The public key of the front terminal has been registered on the blockchain network platform. Therefore, the blockchain node can query from the blockchain network platform according to the merchant number and terminal number of the front terminal.

After querying the public key of the front terminal, the signature information can be verified according to the public key of the front terminal, and the hash value of the electronic certificate is registered in the blockchain after the verification is passed and the consensus of other blockchain nodes In the network. The smart contract running on each blockchain node in the blockchain website verifies the relevant information of the uploaded electronic certificate, mainly by finding the public key corresponding to the front terminal through the merchant number and terminal number, and then using the public key Check the signature information. If the verification is passed, the hash value of the electronic certificate is registered in the blockchain network.

3. The upload pre-processing module is realized by software or hardware, the communication protocol adopts other communication protocols, and encryption is performed during transmission;

4. On the chain is by calling intermediary software services;

5. The public and private key pair of the POS machine is not managed by the certificate management module, but managed by the preprocessing module itself;

6. A POS machine is not determined by the merchant number and terminal number, but by the POS logo.
