Sovereign Verification & Trust Protocol (SVTP) v1.0

This document specifies the Sovereign Verification & Trust Protocol (SVTP), a foundational framework for establishing verifiable identity, attribution, and governance for autonomous machines. SVTP provides a non-repudiable "Root of Trust" for both digital AI agents and physical autonomous systems (e.g., industrial robotics, autonomous vehicles). By defining the SVTP-DID (did:svtp) and the Protocol Seal mechanism, this standard enables secure machine-to-machine (M2M) interaction, automated compliance with NIST-800-218, and institutional-grade liability containment in the machine economy.
