Impossibility within Dynamically Available Protocols by Yash Saraswat | Devcon SEA

Thu, Oct 2, 2025, 12:00 AM

This talk will be about dynamically available protocols and their properties. LMD-GHOST which is the fork choice rule for Ethereum consensus currently can face ex-ante and re-org attacks. GoldFish and other protocols aim to fix this but they themselves then face problems with asynchrony resilience and subcommittees. I also want to present possible solutions to these issues and establish some impossibility results that might be useful in consensus research for path towards single slot finality.
