About Null Halo — verifiable receipts for AI agent actions
Null Halo is Ryan York's security and AI-infrastructure
practice. SSX360 is our public demonstration that every agent
action can produce a hash-linked, signature-bound,
independently-verifiable receipt — with no backend call.
What we believe
- Every autonomous action should leave a receipt.
- Receipts should be verifiable without the issuer.
- The receipt format should be stable, versioned, and reproducible across runtimes.
- The audit trail is the product, not a feature.
