Embodiment 1

[0061] This embodiment provides an auction method based on hybrid blockchain architecture, such as figure 1 and figure 2 As shown, this method includes steps: S1: Obtain the registration application information of the auction institution, and review the registration application information of the auction institution. The account address of PubAddr acu Send to the auction agency; S2: Obtain the registration application information of the bidder, open a second account for the bidder on the public chain, and send the account address of the second account PubAddr bidder Sent to the bidder; S3: When the auction agency initiates an auction request, enter the information of the commodity to be auctioned, and use the account address PubAddr of the first account of the auction agency acu Create an auction smart contract on the private chain, set the end time of the auction, and generate the auction process, and upload the auction information of the auction process to the public chai...

Embodiment 2

[0080] This embodiment provides an auction system based on hybrid blockchain architecture, such as image 3 and Figure 4 As shown, the system includes: Auction agency registration module: used to obtain the registration application information of the auction agency, review the registration application information of the auction agency, and after the audit is passed, open the first account for the auction agency on the public chain, and Set the account address of the first account to PubAddr acu sent to the auctioneer;

[0081] Bidder registration module: used to obtain the registration application information of the bidder, correspondingly open a second account for the bidder on the public chain, and send the account address of the second account PubAddr bidder sent to bidders;

[0082]Auction management module: when the auction agency initiates an auction request, enter the information of the commodity to be auctioned, and use the account address PubAddr of the first acco...

Abstract

The invention relates to the technical field of block chains, and discloses an auction method and system based on a hybird block chain architecture, and the method comprises the following steps: S1, obtaining the registration application information of an auction mechanism, checking the registration application information of the auction mechanism, opening a first account for the auction mechanism on a public chain after the checking is passed, and sending an account address PubAddracu of the first account to an auction mechanism; s2, acquiring registration application information of a bidder, correspondingly opening a second account for the bidder on the public chain, and sending an account address PubAddrbidder of the second account to the bidder; and S3, when the auction mechanism initiates an auction request, inputting information of a commodity to be auctioned. According to the method, the private block chain is used for bidding, the privacy of the bidders and the auction process is protected, only the auction agencies and the bidders participating in the auction process can read the information of the whole auction process, and the invention has better privacy protection capability, lower resource requirements and higher efficiency.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to an auction method and system based on a hybrid block chain architecture. Background technique [0002] In recent years, blockchain has become a key tool for building a decentralized trust mechanism. Public chains such as Bitcoin and Ethereum are more widely used in the field of cryptocurrency. In other fields, deploying information on public chains or public smart contracts may cause sensitive information leakage and require more computing resources. [0003] Existing public blockchains and smart contracts deployed on them can leak sensitive information. While there are some ongoing works utilizing advanced cryptography to address some of these sensitive information leaks, they require significant changes to existing and popular blockchains (e.g. Ethereum) and often require significant computational very big. On the other hand, private blockchains have been propo...
