Anchoring & Execution Roadmap
Transparent phased evolution of receipt verification and anchoring layers.
Current State (Live)
Phase 1, Deterministic Receipts
LIVE- Deterministic policy engine
- Canonical receipt structure (v1)
- SHA-256 receipt_hash
- Public recompute verification
Phase 2, Signed Receipts
LIVE- Ed25519 signature over receipt_hash
- Public key discovery endpoint
- Signature verification API
- Verification Kit UX
Preview State (Not Yet Enabled)
Phase 3, Anchor Preview
PREVIEW- Anchor status model
- Structured anchor_status field
- No on-chain writes
- Roadmap intent only
Planned Extensions (No Guarantees)
Phase 4, Devnet Anchoring
Planned- Anchor receipt_hash to Solana devnet
- Include anchor_tx signature
- Add anchor verification API
Phase 5, Mainnet Anchoring
FUTURE- Mainnet anchoring option
- Batch anchoring support
- Independent third-party verification surface
Phase 6, External Verifier SDK
FUTURE- Standalone verifier package
- Receipt verification without server dependency
- Independent auditor compatibility
Design Principles
- Deterministic first
- Signature before chain
- Chain anchoring is additive, not foundational
- No custody, no asset control
- Verification must remain portable
