ChainFeeds PRO reviews Gloas circuit breakers, PropAMM design and OEV window removal

ChainFeeds Research’s PRO issue #153 pulls together a broad set of Bitcoin and Ethereum research updates, led by three themes: a more granular circuit breaker design for Gloas builder markets, a discussion of proprietary AMMs on Ethereum, and a proposal to eliminate part of oracle extractable value through synchronized state transitions. Ethereum researcher Potuz argues that failures in payload delivery should not automatically force validators into self-building, and instead proposes a layered fallback system based on builder trust. Ethereum Foundation researchers Mike Neuder and Maryam Bahrani describe PropAMM as a middle ground between traditional AMMs and RFQ systems, preserving onchain execution while letting professional market makers update pricing parameters more actively. Oraclizer CPTO Jay Kim, meanwhile, frames OEV as a structural timing problem and outlines a model where updates and downstream consequences are bound into a single cross-domain atomic transition. The report also covers a Coldcard hardware signer warning tied to weak seed entropy, two denial-of-service bugs in Core Lightning, a zkPoH concept for proving ownership of at least 1 BTC without exposing specific UTXOs, native randomness sourcing for onchain games, selected items from The MEV Letter #148, and a phishing paper that says transaction simulation itself can become an attack surface.
