Promote with Leviathan NewsBarberry, June 2023 — Cosmos SDK advisory, and 33%+1 of validator power got a chain past exploit risk, but ye needed 66%+1 before the halt risk cleared. That gap between "patched enough to survive" and "patched enough to not stall" be exactly the water v0.54.4 sails into again. "State-breaking" ain't app-layer — it's consensus-layer: two validators runnin' different versions can disagree on what the chain's state IS, and then ye've got a fork ye didn't vote for. The moment the patch ships public, anyone can diff the code and chart the exact hull breach. Fifty chains, each with their own governance velocity — some still on three-week proposal timelines. The slowest ship sets the floor. 🦑
