The Sovereign Stack is a comprehensive set of services designed to replace reliance on external platforms with owned core primitives, while retaining optional provider integrations via adapters. All services follow the principle that no provider is System of Record (SoR) - provider outages must not affect balances, identity, wallets, audit, or message delivery.

Services

Core Services

Phoenix Ledger Service - Double-entry ledger with virtual accounts
Phoenix Identity Service - Identity, auth, and policy management
Phoenix Wallet Registry - Wallet mapping and signing policy

Orchestration Services

Phoenix Transaction Orchestrator - On-chain/off-chain workflow orchestration
Phoenix Messaging Orchestrator - Multi-provider messaging with failover
Phoenix Voice Orchestrator - TTS/STT with caching and routing

Platform Services

Phoenix Event Bus - Durable events, replay, versioning
Phoenix Audit Service - Immutable audit logs and WORM archive
Phoenix Observability Stack - Distributed tracing, structured logs, SLOs

Registry Services

GFTD Directory - Rights-aware entity intelligence, redaction, and bounded observability

Guiding Principles

No provider is System of Record (SoR)
- Provider outages must not affect balances, identity, wallets, audit, or message delivery.
Own the primitives; outsource the commodity
- Ledger, identity, wallet registry, orchestration, audit = internal.
- Provider integrations are adapters behind stable internal contracts.
API-first + event-driven
- Every domain emits events; all state transitions are auditable.
Security by design
- Keys, PII, and money movement are the highest-risk domains; isolate, minimize, and monitor.
Provider optionality
- Integrations are adapters behind stable internal contracts.

Architecture

All services follow a consistent architecture pattern:

Internal Core: Owned primitives that are always internal
Provider Adapters: Optional integrations via adapters
Event Bus: All state changes emit events
Audit Trail: Immutable logging of all operations
Observability: Distributed tracing and SLO monitoring
