Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a method for bidding an article based on a block chain according to an embodiment of the present invention, which is applicable to a situation how to bid on an article. The method can be applied to a block chain node, and can be executed by a block chain-based commodity bidding device, which can be implemented in a software and/or hardware manner, and can be integrated into an electronic device carrying a block chain-based commodity bidding function, in particular, an electronic device as a block chain node. As shown in fig. 1, the method may specifically include:
and S110, acquiring a transaction processing request which is sent by a bidding participant and comprises commodity bidding information.
In this embodiment, the bidding participant may be a bidding seller or a bidding responder. The auction seller is a party that auctions for a product, and may be, for example, a distribution store; it should be noted that the node to which the auction side of bidding belongs may be a node in the blockchain or may not be a node in the blockchain. The bid responder is a party bidding on an auction product, and may be, for example, a bidding shop; it should be noted that the node to which the bid responder belongs may be a node in the blockchain or may not be a node in the blockchain.
The product bidding information may be product bidding auction information, product bidding response information, or product bidding result information. The product bidding auction information includes, but is not limited to, auction identification information, information type, auction party identity information, auction detail information, and auction party signature. The product bid response information includes, but is not limited to, auction identification information, information type, responder identity information, bid data, and responder signature. The commodity bidding result information comprises auction identification information, information type, auction party identity information, bidding results and auction party signature.
Further, the so-called auction identification information is used to uniquely characterize the process from the initiation of an auction to the end of the auction, i.e. the process of one auction; may be represented by numbers, letters, or numbers plus letters.
The type of information may be a bid request, a bid response, or a bid result; information for bidding on the goods, wherein the bidding request is issued by a bidding auctioneer; the bidding response refers to the response information of the bidding responders who want to participate in bidding on the bidding request; the bid results are bid results that are posted.
The auctioneer identity information is used to uniquely identify the bidding auctioneer, and may include the name, business year, and business size of the bidding auctioneer. The auction house signature can be obtained by encrypting the auction identification information, information type, auction house identity information, auction detail information and the like by using the auction house private key. In order to reduce the complexity of the calculation, further, hash operation may be performed on the contents such as the auction identification information, the information type, the auction party identity information, and the auction detail information to obtain summary information, and then the summary information may be encrypted by using a private key of the bidding auctioneer to obtain an auction party signature. The private key is a private key of the bidding party, the private key corresponds to the public key one to one, and the public key is used for decrypting the signature of the bidding party.
The auction detail information may include, but is not limited to, information of an auction product, a product auction rule, and the like. The auction rule for the product may be set by the bidding auctioneer, for example, the auction responder with the highest bid price may be used as the winner, but the winner need not pay the winning bid price, but only the next highest bid price lower than the winning bid price plus the reserve price, which may be set by the auction responder. It will be appreciated that the advantage of this auction strategy is that the price paid by the winning bidder is lower than the winning bid price, but it is lost to the bidding auctioneer node (i.e., the distribution store). Thus, to reduce the loss of the bidding bidder node, a minimum bid price may be set, thus ensuring that the bid price for each bidding responder node is not less than the minimum price set by the bidding bidder node.
The responder identity information is used to uniquely identify the bidding responder, and may be the name, business year, business scale, and the like of the bidding responder. The responder signature can be obtained by encrypting the auction identification information, the information type, the responder identity information, the bid data, and the like using the responder private key. In order to reduce the complexity of calculation, further, hash operation may be performed on the auction identification information, the information type, the responder identity information, and the bid data to obtain summary information, and then encryption may be performed by using a private key of the bid responder to obtain a responder signature. The bidding data is the bid of the bidding responder for the bid item.
The bid results include the bid responders who bid the winning bid, and the bids for the auctioned item.
In this embodiment, the block link point obtains a transaction request including commodity bidding information sent by the bidding participant through the node to which the bidding participant belongs. Optionally, in the case that the node to which the bidding participant belongs is a block chain node, the block chain node implementing the present embodiment may be the node to which the bidding participant belongs, or may not be the node to which the bidding participant belongs.
Further, in order to ensure the authenticity of the identity of the bidding party, as an optional way of the embodiment of the present invention, after obtaining a transaction request including the commodity bidding information sent by the bidding party, the identity of the bidding party may be verified according to the commodity bidding information, and if the verification is passed, the following steps are continuously executed; if the verification is not passed, the following steps are not continuously executed.
For example, according to the commodity bidding information, the identity of the bidding participants can be verified according to the identity information of the auctioneer or the identity information of the responder in the commodity bidding information. For example, it is possible to recognize whether or not the business years and/or the business scales in the auction rules of the product are satisfied, such as the business years and/or the business scales in the identification information of the auctioning party and the identification of the answering party, and if so, the verification is passed.
