SSI Protocol
Sovereign Synthetic Intelligence
An open governance protocol for autonomous AI systems.
SSI v1.0 defines cryptographic audit trails, layered policy enforcement, and deterministic safety boundaries — implementation-agnostic and open to all.
Protocol architecture
SSI is a layered protocol. Agents MUST NOT execute high-impact actions without a prior Decision from a Kernel. That is the foundational invariant.
Implementations MAY colocate components — the logical separation MUST be preserved.
Protocol primitives
Four normative components defined in the SSI v1.0 specification. Any conformant implementation provides all four.
Versioned, signed policy documents that wrap AI systems with constitutional constraints, operational rules, and escalation paths. The primary mechanism for encoding governance into SSI.
The atomic unit of the audit trail. Every permission evaluation produces exactly one RPX record capturing the request, the decision, the reasoning trace, and the execution result — cryptographically signed.
The normative evaluation core. Loads applicable Governance Envelopes, evaluates requests through a deterministic pipeline, computes a Decision with a full reasoning trace, and emits a signed RPX record.
Normalizes incoming requests from AI agents in any supported protocol format, routes them to Kernel instances, and returns Decisions. Supports HTTP/REST; gRPC and WebSocket optional.
Conformance levels
Any system satisfying the MUST requirements in SSI v1.0 may claim conformance.
Development, research, proof-of-concept
