Abstract
With the development of blockchain technology, the existing online auction technology is developing from the trusted third party as auction intermediary to the disintermediation to the third party. Aiming at the problems existing in the existing sealed bid auction scheme based on blockchain, such as the leakage of bidders' privacy information, illegal acquisition or tampering of bidders' bids in sealed auction, etc. Based on blockchain as the bottom layer, an auction scheme with decentralization, bid privacy, anonymous verifiability, tamper-proof and collusion-proof is constructed. ASVChain uses encryption mechanism to encrypt each bidder's offer to ensure the privacy of the bid, and uses ring signature technology to sign the encrypted offer, providing safe and verifiable steps while ensuring that each bidder's personal information is not leaked, and preventing illegal tampering while resisting collusion. The security analysis shows the advantages of this scheme compared with the existing scheme. The experiment analyzes and tests the influence of the number of bidders on the bidding time, and the results show that the time consumption of the proposed auction scheme meets the daily auction demand.
