Most security systems ask the same question: who should we trust with the keys?
I used to ask it too.
Then I remembered how early nuclear launch protocols were designed. No single person held complete authority. One carried a code, another verified a separate condition, a third could only act under strict constraints. The system was not built to find the most trustworthy individuals. It was built to ensure no single participant could ever complete the critical action alone.
That shift returned when I studied Babylon’s Trustless Bitcoin Vaults (TBV).
At first the model looks like a list of who controls the vault. The clearer picture is who is not allowed to control the Bitcoin. The depositor keeps ownership and signs every spend. The Vault Provider can only submit redemption proofs. Universal Challengers can dispute invalid claims. Vault Keepers act only during liquidation. Even the Security Council can pause payouts in an emergency but cannot redirect the BTC.
The Bitcoin remains locked inside the vault and can only move through pre signed paths. Those paths are fixed in advance. No participant is given the flexibility to invent a new one later.
The more I understood the design, the more it felt like a system organized around limiting what every party is allowed to do, rather than asking users to trust them with broader power.
That is a different security model. It does not try to choose better custodians. It tries to make custody itself less necessary.

Do you think limiting every participant’s authority is stronger than relying on trusted custodians?
