As shown in fig. 5, an embodiment of the present invention provides a lock control method based on a block chain, which is applied to the block chain, and the method includes:
step 501: and deploying the intelligent contracts in the blockchain according to the contract creating transaction sent by the authorization terminal.
Step 502: and transferring the resources in the contract account from the authorized user to the access user according to the transfer transaction sent by the authorized end.
Step 503: and calling an intelligent contract according to the unlocking transaction sent by the access terminal to generate an unlocking transaction identifier and an unlocking transaction result.
And the public key of the authorized user, the unlocking transaction identifier and the unlocking transaction result are correspondingly stored.
The block chain stores the key of the electronic lock in a resource form, and the authorized user transfers the key of the electronic lock by transferring the resource, so that the owner of the resource has the right to unlock. The user may initiate an unlocking transaction for the resource in the account, for example, the resource in the account of the user a represents a key of the electronic lock a, and if the user a wants to unlock the electronic lock a, the user a initiates an unlocking transaction, which is used to invoke the smart contract corresponding to the resource. In one embodiment of the invention, the transfer transaction includes: accessing a public key of a user;
the intelligent contract also comprises: an effective time period;
according to the intelligent contract of the transaction transfer of unblanking that the access terminal sent, generate unblanking transaction sign and unblanking transaction result, include:
and verifying whether the current user is the access user or not according to the public key of the access user, if so, calling an unlocking method in the intelligent contract to determine whether the current time is within an effective time period, and if so, generating an unlocking transaction identifier and an unlocking transaction result used for representing successful execution of the unlocking transaction.
The authorized user and the accessing user may have a pre-agreed validity period, e.g., 14:00-18: 00.
In the embodiment of the invention, the unlocking transaction is signed by the private key of the access user, so that the embodiment of the invention determines whether the current user sending the unlocking transaction is the access user holding resources or not by the public key signature verification of the access user. The invention verifies the unlocking transaction from two aspects of verification effective time and access user, and improves the safety of the electronic lock. In an actual application scenario, whether the current time is within the valid time period or not may be verified, and then whether the current user is an access user or not may be verified, and the two verification processes may also be verified simultaneously.
In one embodiment of the invention, the intelligent contract is an NFT (Non-homogeneous Token) intelligent contract and the resource is NFT. In a practical application scenario, the NFT may be issued on the blockchain based on ERC-721, ERC-1155 protocols, etc., and the NFT serves as a key credential to facilitate the transfer of money. If an authorized user authorizes multiple electronic locks externally, multiple intelligent contracts can be deployed in the blockchain, with each intelligent contract corresponding to an NFT.

Step 702: deploying an intelligent contract according to the contract creating transaction by the block chain; the intelligent contract comprises a public key of an authorized user.
The intelligent contract is an NFT intelligent contract, and the intelligent contract records the following information: identification of the authorized lock, effective time period, public key of the authorized user and unlocking method. And calling an unlocking method to execute: and determining whether the current time is within the effective time period, if so, judging that the unlocking transaction result is successful, and otherwise, judging that the unlocking transaction result is failed. Invoking this unlocking method must hold the signature of the NFT owner, i.e. the unlocking transaction must be signed with the private key of the access user. The public key of the authorized user and the identification of the authorized lock are not allowed to be modified, and the authorized user can modify the valid time period.
The block chain may verify whether the create contract transaction was initiated by the authorized user based on a public key of the authorized user included in the create contract transaction. And if the public key carried in the contract creating transaction is not matched with the private key used by the signature, the block chain does not respond to the contract creating transaction, so that the security of the electronic lock is prevented from being damaged by an illegal user.
After the intelligent contracts are deployed on the blockchain, an NFT is obtained from the contract accounts, and the NFT can be transferred to other users.
The authorization side and the access side can be a blockchain wallet, and can also be other applications capable of implementing the embodiment of the invention.
Step 703: the authorization end sends the transfer transaction to the blockchain.

Step 704: the blockchain transfers resources in the contract account from the authorized user to the access user according to the transfer transaction.
After the smart contract is deployed on the blockchain, the authorized user can view the held NFT through the blockchain wallet and transfer the NFT to the access user through the blockchain wallet, and after the block chain transfers the NFT to the access user from the authorized user, the access user can receive the NFT from the authorized user in the blockchain wallet.
The transfer transaction is signed by the private key of the authorized user, and the blockchain can verify whether the transfer transaction is legal or not according to the public key of the authorized user.
In a practical application scenario, the transfer transaction may further include a transfer method, and whether the transfer transaction is signed by a private key of an authorized user is determined through the transfer method. Specifically, the blockchain calls a transfer method in the intelligent contract according to the transfer transaction to determine whether the transfer transaction is signed by a private key of an authorized user, and if so, resources in the contract account are transferred to the access user from the authorized user.
The intelligent contract can also comprise the following attributes: owner, which is used to record the holder of the key of the electronic lock, i.e. the holder of the resource.
Step 705: the access terminal sends an unlock transaction to the blockchain.
And the access terminal sends unlocking transaction to the blockchain aiming at the NFT held by the access user, and the unlocking transaction is used for accessing the private key signature of the user.
Step 706: calling an intelligent contract according to the unlocking transaction by the block chain to generate an unlocking transaction identifier and an unlocking transaction result; and the public key of the authorized user, the unlocking transaction identifier and the unlocking transaction result are correspondingly stored.
And calling an unlocking method in the intelligent contract according to the unlocking transaction by the block chain to obtain an unlocking transaction result and transaction hash.
Step 707: and the access terminal acquires the unlocking transaction identifier and provides the unlocking transaction identifier for the electronic lock.
And the access terminal queries the block chain to obtain the transaction hash. The electronic lock obtains the transaction hash by scanning the two-dimensional code.
Step 708: and the electronic lock sends the unlocking transaction identification and the stored public key of the lock master to the server side.
And the electronic lock sends the pre-stored public key of the lock master and the transaction hash to the server side.
Step 709: and the server acquires the unlocking transaction result and the public key of the authorized user from the block chain according to the unlocking transaction identifier, verifies the unlocking transaction according to the unlocking transaction result, the public key of the authorized user and the public key of the lock master, and sends a verification result to the electronic lock.
Step 710: and the electronic lock determines whether to unlock according to the verification result.
For the unlocking transaction initiated by the current user, on one hand, the blockchain verifies whether the current user is an authorized user based on the intelligent contract, on the other hand, the server side or the electronic lock can determine whether the authorized user is the lock master by comparing the public key of the lock master with the public key of the authorized user, and the verification results of the two aspects are integrated to determine whether to unlock the electronic lock, so that the safety of remote control of the electronic lock can be improved. The embodiment of the invention saves the ownership of the electronic lock in the block chain in a resource form, prevents the ownership of the electronic lock from being acquired by an illegal user, and simultaneously does not transmit information such as a temporary password or a private key of an authorized user in a network, thereby further improving the safety of the electronic lock.
