Grantex – Delegated authorization protocol for AI agents
OAuth-equivalent for agents: cryptographic identity, scoped grants, audit trail.

Revocable AI signatures solve version drift, but 'no key management' contradicts security basics.

OAuth-equivalent for agents: cryptographic identity, scoped grants, audit trail.
Schnorr signatures + ZK proofs let you verify agent claims without trusting anyone.
TLS for MCP agents with ECDSA passports and L0-L4 trust levels, zero dependencies.
ML-encoded signatures with revocation—clever research primitive, but not cryptographically proven.
Standard crypto signatures on carbon estimates—auditors still can't verify the measurements themselves.
Offline artifact verification with signed governance, but what threat model does this solve?
