How to stop 95% of DeFi Hacks at Scale

This Ethereum Magicians-style proposal argues that two new JSON-RPC methods, eth_clandestineSubmitTransaction and eth_clandestineSubmitBlock, could let MEV Boost relays front-run hacker transactions and recover funds for projects, with the author estimating that about 95% of DeFi hacks would be eliminated. The proposal requires multiple whitelisted security firms to reach a quorum on a malicious transaction before submission, and it says recovered funds would be returned to the project, with an optional portion kept for a pooled insurance treasury and payments to participating security companies. The text acknowledges that hacks can still occur if an attacker runs their own validator and builds the block locally.
