Notes from people who logged real key events.

After finishing the dual-control module in Vault Discipline Fundamentals, our two-person approve flow stopped living in Slack screenshots. The tracker columns for “witness present” and “backup verified” are now mandatory before any device ships.

★★★★☆ 4/5 — Ledger Lite was enough for my solo setup. Module 2’s seed-location map felt repetitive if you already keep a metal backup, but the event timestamps were new to me.

I joined for the Private Key Handling Tracker overview page and stayed for Chain Steward. Still wish the office hours had more breakout time — the lost-device drill itself was sharp.

Client in fintech operations: “We adopted the rotation calendar from Module 4. Not every engineer liked the paperwork, yet our last audit asked fewer follow-ups about who last touched the signing laptop.”
