Background

Auction is an ancient bidding game in human history, which evolves to today in three main forms, the first is an english auction, bidding from low to high, and the highest bidder; the second is a dutch auction, with bids going from high to low, obtained by the first bidder; the third is a secret quotation mode, wherein the participant only reports one price and the highest bidder gets. In the first auction, when the auction is a valuable and rare object, the auction participants may block the auction information or delay the spread of the auction information; as society becomes more and more digital, more digital assets become photos, such as electronic art pictures, technical patents, etc., which often require higher cost to verify right ownership in traditional auctions; when informatization becomes a common base for the entire society, the network auction also gradually becomes a new auction form, but in this form, more problems will arise, such as how the participants know in the third secret bid how do the organizing party not reveal everyone's secret bid to others? And how does the participant know that the other's bids he sees are not mouse-set by the back-end administrator in the first auction? In the second auction, how does he know that others are really bidding before himself when the participant has not taken a auction? At present, no good solution exists other than by introducing a supervising authority and adding credit endorsements, and nevertheless, the participants still cannot fully trust the organizing party because the organizing party still has the ability to do joint cheating with the supervising party. Therefore, how to effectively solve the problem that the auction process is trusted by participants, the auction organizer can not cheat any more, and the auction process can be well promoted by the auction organizer, which becomes an urgent problem to be solved.
