Abstract: M + 1st-price auction, also called Vickrey auction, is a type of sealed-bid auction to sell M identical goods. B bidders secretly choose a price from P bidding points as their bid. The top M bidders can buy the goods at the M + 1st bidding price. A trusted manager is commonly used to compare these sealed-bids. In our research, trusted manager and trusted mix servers used by mix and match are removed. Instead of cooperating all managers or bidders to find out the winning bidders, winning bidders prove that they are a winner by themself. By further adopt a greedy strategy on searching the M+ 1st-price, the time complexity of each bidder can be reduced to O(P), which is the same as most previous researches. Thus, we construct a scheme that removed the manager without increasing bidders’ time complexity. The implementation shows that the gas usage reduced 87% from a manager architecture in a 3 bidder and 6 bidding price setting. The cost to participate in this auction is 12, 000, 000P gas or 600P US dollars at this moment, which is enough practical.
