My phone can update overnight. A signed mortgage cannot quietly rewrite itself.
That difference kept coming back to me while looking at how Babylon TBV handles protocol upgrades.
Several Ethereum-side contracts can evolve through governance, with changes passing through a Timelock Controller before taking effect. But a live Bitcoin vault is not treated like an app account that automatically inherits every new setting.
Its Bitcoin spending paths were agreed and pre-signed at creation. Challenge-related timings are also versioned, and an existing vault keeps the values assigned when it was created.
At first, that looked like an obvious advantage.
Imagine governance later changes the challenge window to improve efficiency. New vaults may use the updated version, while an older vault continues under the window its depositor originally accepted. The rules protecting already-locked BTC do not quietly move beneath the user.
But predictability creates another problem: version fragmentation.
As the protocol evolves, Vault Providers, challengers, recovery tools, and interfaces may need to recognize several generations of vaults at once. A newer version could contain better parameters or stronger safeguards, yet an existing vault would not automatically receive them.
Migrating may require exiting the old vault and creating a new one, rather than changing the Bitcoin transaction graph already committed onchain.
So an old vault is not necessarily outdated by accident. It may be preserving a promise.
That changed how I think about upgradeability. The protocol needs enough flexibility to fix tomorrow’s problems, but not so much that governance can silently alter yesterday’s commitments.
For long-lived native Bitcoin collateral, what matters more: automatically receiving the newest protocol rules, or knowing that the safety conditions you entered under will remain unchanged??
