It can be understood that, in other embodiments, the above-mentioned modules may also be program instructions or firmware solidified in the processor 10.

The generating module 101 is used for generating smart contracts according to bidding rules.

In this embodiment, the smart contract is a piece of code stored and running on the blockchain network. It is an activity rule and related agreement recognized by the parties involved in a certain activity, and these rules and agreements are used by The way the code is expressed, it is executed on the blockchain network. The smart contract allows for credible transactions without a third party, which are traceable and irreversible.

In this embodiment, the bidding rule is that the bidding number is greater than or equal to the bidding number, and it is determined that the user with the smallest bidding chip is the winning user. That is, the content of the smart contract includes that the bid number is greater than or equal to the bid number, and the user with the smallest bidding chip is determined to be the winning user. Wherein, the bid number is the queuing number of the user.

The receiving module 102 is used for receiving the bidding number sent by the queuing device 2 through the smart contract.

In this embodiment, when the queuing number device 2 does not respond within a preset time after calling a queuing number, the queuing number is sent to the electronic device 1. After receiving the queuing number, the receiving module 102 sets the queuing number as a bidding number, and sends the bidding number to the mobile terminal 3 of the user currently queuing.

The receiving module 102 is also used to receive bid applications sent by the mobile terminals 3 of a plurality of users through the smart contract.

In this embodiment, the bid application at least includes the user's queuing number and private key. Wherein, the private key is used to encrypt the bid application. The receiving module 102 decrypts the bid application by the public key to obtain the user's queuing number. Wherein, the public key is generated by performing an encryption algorithm based on the private key.

The calculation module 103 is used to calculate the bidding chip value of each bidding user according to the bidding number and the queuing number of each bidding user.

In this embodiment, the bidding chip value=queuing number-bidding number+1. For example, when the bidding user's queuing number is 20 and the bidding number is 12, the bidding chip value is 9.

The sending module 104 is used to send the bidding chips of each bidding user from the user account address to the smart contract address.

In this embodiment, the user account address is the network address of the user account in the blockchain, and the smart contract address is the network address of the smart contract in the blockchain.

In this embodiment, the calculation module 103 also sends the bidding chip value of each bidding user to the mobile terminal 3 of the corresponding bidding user. When the mobile terminal 3 of the bidding user receives the bidding chip value, The value of the bidding chips is converted into bidding chips according to preset rules. In this embodiment, the preset rule is that the bidding chips are equal to the value of the bidding chips. For example, when the bidding chip value is 9, the bidding chip is 9 yuan. In other implementation manners, the preset rule is that the bidding chip is equal to the member points of the same amount of the bidding chip value. For example, when the bidding chip value is 9, the bidding chip is 9 member points.

The determining module 105 is configured to execute the smart contract according to the bidding chips of each bidding user to determine the winning user of the bidding number.

In this embodiment, according to the smart contract, the determination module 105 determines that the user with the smallest bidding chip is the winning user of the bidding number. For example, when A’s bidding chip is 9 yuan and B’s bidding chip is 31 yuan, the determination module 105 determines that A is the winning user of the bidding number.

The storage module 106 is used to store the bidding information in the block and write it into the block chain through a consensus mechanism.

In this embodiment, the bidding information includes the smart contract, the bidding number, user account information participating in the bidding, the bidding chip value of each bidding user, and the bidding result.

The sending module 104 is also used to send the bidding result to the mobile terminal 3 of the winning user.

The return module 107 is used to return the bidding chips of the unsuccessful user to the account address of the unsuccessful user.

The sending module 104 is also used to send control instructions to control the queuing number calling device 2 to call number according to the bidding result.

In this embodiment, the control instruction includes the queuing number of the winning user. When the queuing number calling device 2 receives the control instruction, it calls the queuing number of the bid-winning user.

The verification module 108 is used for verifying the queuing number, blockchain address and private key of the winning user when the winning user handles the business. In this embodiment, the blockchain address is generated by encrypting the private key sent by the mobile terminal.

In this embodiment, when the queuing number is the same as the winning queuing number, the blockchain address is the same as the address of the block of the bidding transaction in the blockchain, and the private key When it is the same as the private key when sending the bid application, it is determined that the queuing number, the blockchain address, and the private key of the winning user are verified. When the queuing number is different from the winning queuing number, the When the blockchain address is different from the address of the block of the bidding transaction in the blockchain or the private key is different from the private key when sending the bid application, determine the queue of the winning user The number, blockchain address, or private key is not verified, and the user cannot handle the business.

The broadcasting module 109 is used for broadcasting the bidding information.

The broadcasting module 109 sends the bidding information to the mobile terminal 3 of each bidding user according to the blockchain, thereby broadcasting the bidding information.

Please refer to FIG. 4, which is a flowchart of the method for bidding for queuing numbers based on blockchain provided by the present invention. According to different needs, the order of the steps in the flowchart can be changed, and some steps can be omitted.
