Why Existing Custody Evaluation Fails

Most custody analysis focuses on components: hardware wallets, multisignature setups, service providers, or isolated security features. This is necessary but incomplete.

It does not adequately evaluate:

Structural failure
How custody systems degrade over time without any adversarial event.
Coordination breakdown
Whether participants can reliably execute recovery across time and turnover.
Entropy-driven degradation
The accumulation of undocumented changes, knowledge loss, and procedural drift.
Dependency concentration
Reliance on single devices, providers, or individuals as unacknowledged failure points.
Jurisdictional constraints
Legal, regulatory, or geographic conditions that restrict access or compel disclosure.
Long-horizon recoverability
Whether the system remains recoverable years or decades after initial setup.

As a result, systems that appear secure at deployment may still fail under real-world conditions. The Bitcoin Custody Standard addresses this gap by evaluating custody as a structural system.
