Trust infrastructure for the agent economy

AI agents operate on unverified context. We provide the cryptographic provenance layer—C2PA credentials, DIDs, verifiable capabilities, and runtime policy enforcement.

Noosphere trust network

When Agent A tells Agent B something, how does Agent B know where it came from, who authored it, or if it's been tampered with?

Inferred context

Agents guess where data comes from based on retrieval paths, not cryptographic proof.

Implicit trust

No mechanism to verify capabilities or authorization across organizational boundaries.

No runtime enforcement

Policies exist in docs, not in cryptographically-enforced attestations.

The provenance layer for AI agent context

01

Sign under policy

Content and context get C2PA credentials with Cedar policy attestations. Every artifact carries proof of origin, authorization, and constraints.

02

Build the trust graph

Organizations declare trust relationships that form a crawlable web. No central authority—trust emerges from the network.

03

Validate at runtime

Before acting on context, agents verify credentials, check trust paths, and evaluate policies. Deterministic, auditable decisions.
