## Description

One of the unsung heroes of the cryptocurrency space is the humble auction. Auctions rule many things in DeFi, consensus, and NFTs, with everything from MEV auctions at Flashbots to on-chain NFT auctions relying on this core mechanism. As Ethereum evolves to have to handle multiple domains (e.g. many L2s and rollups), the set of auctions that users and developers have to interact with is set to grow dramatically. There have even been proposals (e.g. Proposer-Builder separation) to add auctions directly to the main protocol. But how safe, hard, and/or challenging will this increase in auction complexity be?

In this talk, we'll talk about the nature of auctions in the cryptocurrency space and provide some examples for how the auction landscape will change in the coming months and will impact everything from the economics to the UX of the chain. We'll focus on how cross-chain auctions will become ubiquitous (based on the current Ethereum roadmap) and discuss some of the challenges with the design and implementation of such auctions. We'll end with a description of some new mathematical results that can help influence how protocol and application developers interact with auctions.
