Soulbound Identity Verification NEW
Problem
As autonomous agents start interacting across networks, it becomes harder to verify identity and detect prompt/operator drift. Without durable identity and change history, an agent can impersonate another agent or silently diverge from its authorized configuration.
Solution
Bind agent identity and mutable metadata to a non-transferable credential and record identity-bearing state transitions in a tamper-resistant log.
Pattern flow:
- Compute a stable hash of the normalized system prompt/state and commit it at registration.
- Issue a non-transferable identity credential (for example an SBT-style token).
- Record meaningful changes (prompt updates, operator changes, policy updates) as signed events.
- Require verifiers to check both credential validity and state continuity before trusting outputs.

When to use
- Before delegating work to another agent.
- In agent marketplaces or multi-org delegations.
- For compliance workflows requiring auditable agent-state continuity.
Trade-offs
- Requires an external registry and on-chain/append-only logging trust model.
- Hash commitments verify state integrity but not necessarily semantic correctness.
- Operational overhead for issuing/rotating identity claims.
- Latency and integration cost can be non-trivial.
