Completa la capa de contratos: los 4 templates buildables migrados a ink! 6.0.0-beta.1 (17 tests verde). El 5º (mdk-reconciliation) es design-only (DESIGN.md, sin código Rust — nada que migrar). origin-credential-mint: migración ink! v6 (Address/U256/StorageLayout). Su issue() ya era CEI-correcto (muta estado antes del transfer) — es el template que el roadmap cita como referencia. 4 tests verde (+ guard test). NOTA: FIX-4 (verify de issuer_signature on-chain) sigue pendiente — necesita el payload canónico de credencial + precompile Ed25519 (Phase 3.x), no es parte de la migración. FIX-1 V1-H7 (escrow): enforce Σ milestone.amount <= total_amount en add_milestone (previene sobre-liberación) + completion vía milestone_total + sweep terminal del residual no-asignado al depositor (deposited − milestone_total). 5 tests verde (+ test del invariante con set_caller). El sweep (transfer) se valida E2E en nodo — node-gated. 17 tests verde totales (escrow 5 + staking 4 + nft 4 + credential 4). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
origin-credential-mint — Cryptographic Credentials Template (Slice 3.4)
Third foundational template del Origin Contract Atelier. Ed25519 + BLAKE3 academic/professional/KYB credentials. Sussi Ethos schema integration.
Use cases
| Use case | Issuer | Holder |
|---|---|---|
| Diploma universitario | UCLA / Universidad | Estudiante |
| Professional cert (PMP, AWS) | Certification body | Profesional |
| Sussi Ethos KYB Nivel 3+ | Oracle Pillar 6 | Institución |
| Atelier skill mastery | Marihan Atelier | Originner student |
| Origin Wallet identity | Foundation Oracle | Originner ciudadano |
CredentialType enum (5 variants)
- Academic: diplomas, transcripts, university credentials
- Professional: industry certifications (PMP, AWS, Microsoft, etc.)
- Kyb: Sussi Ethos Oracle KYB institutional verification
- Skill: Marihan Atelier skill mastery post-Meta Entorno completion
- Custom: user-defined schema extension
Schema canonical (Sussi Ethos integration pending)
Each credential = (issuer + holder + schema_type + data_hash + signature + dates):
- data_hash: BLAKE3 del JSON-LD credential data (off-chain Hypercore storage)
- issuer_signature: Ed25519 sobre
(holder + schema_type + data_hash + issued_at + expires_at) - expires_at: Optional canonical (None = perpetua, Some(N) = expires at block N)
On-chain verification de Ed25519 signature pending Phase 3.x — currently signature stored para off-chain verification via sp_io::crypto::ed25519_verify host function precompile.
