Inverse Generalized Second Price

Definition

Inverse Generalized Second Price is an auction mechanism where bidders pay the second-highest price for their winning positions. This is a specific type of auction theory mechanism, often applied in digital advertising or blockchain transaction fee markets, where winning participants pay a price determined by the second-highest bid among their competitors, rather than their own bid. The “inverse” aspect typically refers to scenarios where the auction seeks to allocate resources (like block space) to those who offer the lowest acceptable price. This design aims to encourage truthful bidding and efficient resource allocation in competitive environments.
