Analysis of equivocation attacks in Ethereum's mev-boost and ePBS systems
Summary
This article analyzes "equivocation attacks" in the context of mev-boost and ePBS (execution payload building separation) within Ethereum's proof-of-stake consensus mechanism. The authors, Francesco D'Amato and Mike Neuder, examine how validators can equivocate (submit conflicting messages) to exploit the MEV-Boost infrastructure and proposed ePBS designs. The research identifies specific attack vectors where relayers and proposers might face risks from equivocation, and discusses implications for Ethereum's block construction and proposer-builder separation models.
