            Sovereign Autonomous Trust Protocol (SATP) v1.0
                        draft-sovereign-satp-00

Abstract

   This document specifies the Sovereign Autonomous Trust Protocol
   (SATP), a foundational framework for establishing verifiable
   identity, attribution, and governance for autonomous machines.  SATP
   provides a non-repudiable "Root of Trust" for both digital AI agents
   and physical autonomous systems.

1.  Introduction

   The proliferation of autonomous systems has created a "Trust Gap."
   SATP addresses this by establishing a decentralized,
   cryptographically anchored identity standard.

2.  Terminology

   SATP  Sovereign Autonomous Trust Protocol.

   Root of Trust (RoT)  The foundational cryptographic anchor.

   Autonomous Machine (AM)  Any software or hardware entity capable of
      independent decision-making.

   Controller Entity  The legal organization responsible for the
      machine.

3.  The Three Pillars of Trust

3.1.  Pillar I: Decentralized Machine Identity (DID)

   Every autonomous unit is issued a permanent did:satp identifier
   anchored to a verified institutional controller.

3.2.  Pillar II: Just-In-Time (JIT) Authorization

   SATP enforces a "Zero-Trust" model, issuing JIT authorization for
   specific tool-calls or mechanical operations.

3.3.  Pillar III: Immutable Audit Chain

   Every action is recorded to an NDJSON-based Usage Ledger, hashed and
   chained for tamper-proof auditing.

4.  Technical Architecture

4.1.  Cryptographic Primitives

   Utilizes Ed25519 for signatures and SHA-384 for ledger integrity.

4.2.  High-Velocity Anchoring (6.42us)

   Achieves a mean Anchoring speed of 6.42 microseconds for mass-scale
   industrial deployment.

4.3.  Autonomous Self-Healing

   Initiates autonomous recovery and rollback to the last verified
   anchor in the event of a breach.

5.  Implementation Accessibility

   Designed for transparent integration via a cryptographic proxy,
   enabling one-line standard implementation.

6.  Conclusion

   SATP is the definitive standard for the machine economy, enabling
   safe deployment at a multi-trillion dollar scale.
