Second-Price Auction Model

Mechanism

The second-price auction model, also known as a Vickrey auction, dictates that the highest bidder wins the auction but pays a price equal to the second-highest bid. In the context of blockchain transaction fees, this mechanism aims to encourage participants to bid their true valuation for blockspace, as bidding higher than their true value offers no additional benefit and bidding lower risks losing the auction. This model is designed to improve bidding efficiency.
