| Abstract(in English) | The second-price auction is an auction method that participants submit their bids all at once and the bidder who bid the highest price makes the purchase a good with the second highest bid amount. In previous scheme, however, there is a problem that information is leaked to the auction manager. We propose an expanded protocol which can be publicly verifiable and keep information secret from the auction manager while ensuring financial fairness using smart contracts. |
