Comparing Auction Methods in DeFi: Dutch Auctions vs Batch Auctions
Comparing Auction Methods in DeFi: Dutch Auctions vs Batch Auctions
🔑 Auction Showdown: Dutch vs Batch
The article examines the shortcomings of automated market makers (AMMs) in decentralized finance (DeFi), such as exposure to miner extractable value (MEV) attacks. It then discusses the benefits of auction mechanisms like Dutch auctions and batch auctions as alternatives to AMMs. Dutch auctions offer solver competition, MEV protection, but are centralized. Batch auctions group multiple orders, enable cross-asset swaps, and incentivize better execution while retaining MEV protection. The article highlights CoW Swap as a major implementation of batch auctions, detailing its approach of collecting order intents, conducting auctions for solvers, and executing winning orders on-chain. It suggests batch auctions aligning with Ethereum's block auction mechanism make them well-suited for DeFi trading.
