Private, Anonymous, Collateralizable Commitments vs. MEV
arxiv(2023)
摘要
In this work, we introduce the private, anonymous, collateralizable
commitments (PACCs) framework. PACCs allow any smart contract wallet holder to
collateralize a claim, request, or commitment in general, in a private and
anonymous manner. PACCs can prove arbitrarily much or little about the wallet
generating the commitment, and/or the transaction which is being committed. We
demonstrate that PACCs can be applied to effectively eliminate
maximal-extractable value (MEV) in DeFi where it currently occurs, shifting MEV
instead to censorship. After describing our protocol with detail, we provide an
implementation using the Ethereum blockchain, and whose benchmarks prove how
PACCs are completely feasible.
