The Prove-Transform-Verify (PTV) Protocol for Attested Agent Identity

This document specifies the Prove-Transform-Verify (PTV) protocol for hardware-anchored, zero-knowledge attested agent identity in federated environments. PTV addresses the data gravity problem in centralized security models by enabling cross-domain agent authorization without raw data exposure. The specification includes: TPM 2.0/secure enclave roots of trust; Groth16 zero-knowledge proofs (<200ms generation on commodity edge hardware); HotStuff Byzantine Fault Tolerant consensus for immutable audit trails; and Sovereign Bound metadata for jurisdiction-aware attestation chains. Use cases include healthcare clinical decision support systems (CDSS), critical infrastructure industrial control systems (ICS/OT), and cross-border regulatory compliance scenarios under GDPR/HIPAA frameworks.
