# Identity Bridge

> Identity Bridge is an obligation-first access architecture that converts anonymous traffic into scoped, revocable authority — without accounts, profiles, or persistent identity. It is created and authored by Zach Shallbetter (https://zachshallbetter.com).

Identity Bridge treats identity not as a gate, but as an optional outcome of a high-value interaction. It optimizes simultaneously for privacy compliance and conversion speed by keeping strangers anonymous until a real obligation appears, then enforcing privacy with the same discipline it enforces access.

## Core concepts

- **Boundary-Native Architecture:** Systems are designed around enforceable separation boundaries first, composing later — rather than centralizing and protecting after the fact.
- **Scoped Authority:** Authority is context-bound, temporary, conditional, and revocable. The system asks "what capability is allowed right now?" instead of "who is this user?"
- **Collapse Resistance:** The system structurally prevents independent data planes from being reconstructed into a unified identity graph.
- **Sealed Envelope Architecture:** Systems cooperate only through signed, minimal, purpose-bound exchanges — bounded visibility, tamper evidence, contextual authority.
- **Temporal Containment:** Authority and correlation decay over time by design, via expiring capabilities, rotating HMACs, and bounded retention.
- **Referential Minimalism:** Systems exchange the minimum reference needed to complete an action, avoiding global user IDs or shared correlation keys.

## Slogans

- Traditional systems ask who someone is. Boundary-native systems ask what is allowed right now.
- Privacy is not a policy when correlation is structurally impossible.
- Systems should compose through capabilities, not accumulate through profiles.
