Implement ADR-004 Phase 1 - the Ancora (Latin for "anchor") contract
provides Merkle root anchoring for off-chain data with proof verification:
Core Features:
- Data root management: Track Merkle roots per VitaID and DataType
(Medical, Education, Investment, Documents, Custom)
- Provider registry: Committee-managed authorization for data providers
with rate limiting and cooldown periods
- Proof verification: Verify Merkle proofs against anchored roots
supporting SHA256, Keccak256, and Poseidon algorithms
- GDPR erasure: Right-to-be-forgotten workflow with pending/confirmed/denied
status and configurable grace periods
- Data portability: Generate attestations for cross-system data transfer
Contract Methods:
- registerProvider/revokeProvider: Committee authorization for providers
- updateDataRoot: Anchor new Merkle root with version tracking
- verifyProof: Validate leaf inclusion against anchored root
- requestErasure/confirmErasure/denyErasure: GDPR erasure workflow
- generatePortabilityAttestation: Data portability support
Cross-Contract Integration:
- Vita: Identity verification via ExistsInternal/OwnerOfInternal
- Tutus: Committee authority for provider management
State Types (pkg/core/state/state_anchors.go):
- RootInfo: Merkle root metadata with version and algorithm
- ErasureInfo: GDPR erasure request tracking
- ProviderConfig: Authorized provider configuration
- StateAnchorsConfig: Global contract settings
- Enums: DataType, TreeAlgorithm, ErasureStatus
Contract ID: -27
Tests (15 test cases):
- Configuration and query tests
- Provider registration/revocation tests
- Authorization and error handling tests
- Data type and algorithm validation tests
