An embodiment of the present invention provides a block chain network-based computational power contract generation method, which is a flowchart of a block chain network-based computational power contract generation method according to the present invention, as shown in fig. 1, and the method includes:
and S1, receiving a calculation force request sent by a user in the block chain network, wherein the calculation force request comprises calculation force demand information, a user public key and a ciphertext.
In this embodiment, the calculation force requirement may include information such as a calculation force type, a calculation force size, and a calculation force usage time.
The calculation power types include buy calculation power and sell calculation power.
The calculation force magnitude includes T numbers of different calculation rates, for example, 110T for a high calculation rate, 65T for a medium calculation rate, and 12T for a low calculation rate, where 1T (H/s) is 1000G (H/s), and 1T (H/s) means that 1 trillion hash collisions are performed per second, and the more hash collisions are performed, the faster the calculation efficiency is.
The user public key is a public key, belongs to the user, and is input with the user public key and the ciphertext when the computing power request is sent out in the blockchain network, so that the user public key and the ciphertext are used for verifying that the request comes from the operation of the user and is not a request submitted by artificial tampering, the user directly initiates the computing power request in the blockchain network, a third party (such as an enterprise or a service provider) is not required to provide data corresponding to the computing power request of the user, the reliability of the user request is ensured, and the user experience is improved.
For example, in one embodiment, a computing power request issued by a user in a blockchain network requests to buy 110T computing power for 2 years, which includes an input user public key and a ciphertext, wherein the ciphertext is generated by a user private key and a text entered by the user through an asymmetric encryption algorithm and is a series of character strings, for example, the ciphertext is:
“MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDC7kw8r6tq43pwApYvkJ5laljaN9BZb21TAIfT/vexbobzH7Q8SUdP5uDPXEBKzOjx2L28y7Xs1d9v3tdPfKI2LR7PAzWBmDMn8riHrDDNpUpJnlAGUqJG9ooPn8j7YNpcxCa1iybOlc2kEhmJn5uwoanQq+CA6agNkqly2H4j6wIDAQAB”。

For example, the words entered by the user in the above example are decrypted by the asymmetric encryption algorithm as follows: and if the Chinese is the 'I' person, the verification is passed.
Asymmetric encryption algorithms require two keys: public key (publickey) and private key (privatekey). If the public key is used for encrypting data, the data can be decrypted only by using a corresponding private key; if the data is encrypted with a private key, it can only be decrypted with the corresponding public key. Because two different keys are used for encryption and decryption, the communication data can be effectively prevented from being tampered, and the safety of the security data is improved.

And S4, generating a calculation contract corresponding to the user request according to the acquired calculation contract template, and sending the calculation contract to a user side.
In this embodiment, a character string is extracted from the calculation demand information according to the user request; extracting fields corresponding to the character strings from the calculation force contract template corresponding to the distributed account book recorded with the calculation force demand information; and finally, filling the extracted character strings into the corresponding fields to generate a calculation force contract corresponding to the user request for user verification and signing.

a verification step: verifying the user public key and the ciphertext through an asymmetric encryption algorithm, and recording the calculation force demand information into a distributed account book if the verification is passed;
an acquisition step: acquiring an computing power contract template corresponding to the computing power demand information from a preset contract template library according to the recorded distributed account book; and
a generation step: and generating a calculation contract corresponding to the user request according to the acquired calculation contract template, and sending the calculation contract to a user side.
7. The electronic device of claim 6, wherein the asymmetric encryption algorithm decrypts a ciphertext corresponding to the user public key according to an RSA algorithm of an encryption and decryption rule.
8. The electronic device according to claim 6, wherein the generating of the computing power contract corresponding to the user request according to the obtained computing power contract template includes:
extracting a character string of the computing power demand information contained in the user request;
extracting a field corresponding to the character string according to the acquired calculation force contract template;
and filling the acquired character strings into corresponding fields to generate a calculation force contract corresponding to the user request.
9. The electronic device of claim 6, wherein the verifying step comprises:
and if the user public key and the ciphertext verified by the asymmetric encryption algorithm do not pass, generating unmatched information of the calculation force request and feeding the unmatched information back to the user side.
10. A computer-readable storage medium, wherein the computer-readable storage medium includes a contract generation program, and the contract generation program, when executed by a processor, can implement the steps of the block chain network-based computational contract generation method according to any one of claims 1 to 5.
