I thought losing control of Bitcoin meant losing the private key.

Babylon revealed a quieter possibility:

The key survives, but the recovery path does not.

A Trustless Bitcoin Vault may depend on more than one secret. Protocol artifacts created when the vault begins can later matter during a self-claim or when challenging an invalid claim.

That turns self-custody into something users rarely prepare for.

Not only key custody.

Long-term evidence custody.

The BTC can remain securely locked. The cryptography can remain correct. No custodian has to betray anyone.

Yet the user may still face a practical failure if a critical file is deleted, corrupted, left on an old device, or never recognized as essential in the first place.
Nothing breaks on-chain.

But ownership becomes harder to exercise.

This matters because time changes the burden. A seed phrase is widely understood as permanent. Protocol artifacts may look temporary, technical, or replaceable—even when the future exit depends on them.

Babylon can design a permissionless recovery path.

It cannot assume every depositor will preserve the tools required to use that path months or years later.

That is the hidden difference between owning an asset and remaining operationally capable of recovering it.

Self-custody should not mean discovering the backup requirements during a crisis.

Because a trustless exit is only truly trustless when the user can still activate it.

Babylon may protect the Bitcoin perfectly.

The harder challenge is protecting the user from forgetting what else must survive.
