Detailed Description
The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the invention, but are not intended to limit the invention in any way. It should be noted that it would be obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit of the invention. All falling within the scope of the present invention.
The invention discloses an auction method of a fixed quantity of targets based on a block chain, which comprises the following steps: generating an auction intelligent contract: generating an intelligent contract according to the auction rule; receiving an auction application of an auction player: receiving an auction application submitted by an auction player, and sending an auction confirmation message to the auction player submitting the auction application aiming at the auction application; accepting the bidding of the auction participants: receiving auction bids sent by the characteristic value account within a fixed time period; and sending a successful auction result certificate: after a fixed time period, executing an intelligent contract to obtain an auction result, sending the auction result to an auction user, receiving an auction result confirmation message sent by the auction user, sending a redemption voucher to a successful auction user, and receiving a redemption voucher confirmation message sent by the successful auction user; storing auction information: storing the auction information in the blocks, and writing the auction information into the block chain through a consensus mechanism. The auction method of the fixed quantity of the targets based on the block chain further includes the steps of receiving the identity registration information of the auction participants: and receiving the bidding auction registration information of the bidders, and generating a characteristic value account uniquely identifying the identity of the bidders according to the bidding auction registration information.
The auction participants handle the procedure of bidding auction registration, obtain the address of the block chain, the public key and the private key pair, log in the account, and check the balance. Preferably, in the auction method for auctioning the car credit, each account corresponds to the automobile driver license number of the auctioneer one by one. The bid auction registration procedure can employ an online or offline transaction. After the account of the auction participants is created, the node form in the block chain is formed for later storage, the block chain node point related to the auction also comprises a unit for holding the auction and a management unit for a fixed number of objects, preferably, in the auction method for auctioning the automobile quota, the management unit is a vehicle management unit.
As shown in fig. 1, a vehicle management unit creates an intelligent contract used in the auction, and publishes a bid delivery amount, an alert price, an auction flow, an auction rule, and the like of the auction. The intelligent contract comprises modules of bid range restriction, real-time bid mean value updating, final auction sequencing and the like. When the auction starts, the auction participants need to send specific information, such as effective bidding, application information for participating in the auction, etc., to the intelligent contract before the designated time point, i.e., before the auction confirmation time point. And after receiving the auction participation application information, the intelligent contract sends auction participation confirmation information to the auction participants. After a specified point in time, the smart contract will send the average of all current bids to the bidder for a fixed time interval, e.g., 1 minute, with the initial bid being the alert bid. Before the auction is finished, the auction participants can bid according to the average price, namely, the auction participants can send own quotation to the intelligent contract. The bids are subject to fixed rules, such as bidding within a fixed range around the average price. At the end of the auction, the intelligent contract will determine successful and losers of the auction according to a fixed rule, for example, a fixed number of participants closer to the average price will be considered successful. The intelligent dating sends the information of successful auction to the successful auction participants and sends the information of failed auction to the losers. After receiving the corresponding message, the auction player sends confirmation information. The intelligent contract sends a successful auction certificate, such as an encrypted key, a unique token and the like, to the successful auction user as a unique certificate of the exchange authority of the object. And the successful auction player sends confirmation information. The information of the auction, including the users participating in the auction, the results of the auction, the bids of the participants, etc., are packed into a block. The nodes on the block chain are identified according to an identification algorithm, preferably, the identification algorithm adopts popular POS and PBFT. After the consensus is completed, the block is recorded on the blockchain. Each participant needs to pay the auction commission fee to complete the auction. The successful person of auction can pay the auction gold and select the number by the voucher, and the information related to auction, such as the license number of the motor vehicle and the license plate number, will be recorded in the database of the server. After the successful auction player obtains the license plate, the blockchain account of the successful auction player is frozen.
Those skilled in the art will appreciate that, in addition to implementing the systems, apparatus, and various modules thereof provided by the present invention in purely computer readable program code, the same procedures can be implemented entirely by logically programming method steps such that the systems, apparatus, and various modules thereof are provided in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Therefore, the system, the device and the modules thereof provided by the present invention can be considered as a hardware component, and the modules included in the system, the device and the modules thereof for implementing various programs can also be considered as structures in the hardware component; modules for performing various functions may also be considered to be both software programs for performing the methods and structures within hardware components.
