The dependency, and how Signura removes it
As AI agents begin to act across organisational boundaries, they hit the same dependency each time: to proceed, an agent must rely on a counterparty's claim — that a licence is valid, a policy is in force, a certification holds, or a permission has been granted. Re-verifying each claim from source, pairwise, is slow and often impossible, and it scales combinatorially as more parties interoperate. That leaves an agent with two poor options: trust the claim blindly, or refuse to act. Neither is acceptable when a human carries fiduciary duty for what the agent does.
Signura closes the gap with transferable reliance backed by an accountable party. An issuer signs a claim and names who stands behind it, with scope and liability defined in advance. When a relying agent needs to act, it fetches the cryptographic proof, verifies it at the moment of decision, checks freshness and revocation status, and keeps the proof as evidence. The checking work is done once and signed for, so reliance costs a fraction of a fresh verification.
The exchange is deliberately neutral: it sits between issuers and relying agents and takes neither side's part. Humans remain in the accountable role. Issuers decide what they will stand behind; relying-party governors decide which issuers and attestation types their agents may depend on, and within what limits. Every reliance event is logged, so a governor can later show precisely which attestations were verified and that they were unaltered.
