KryptoOS Integration

Ouranoos uses KryptoOS for user and provider device identity without exposing PII on-chain.

SDK

kryptoos_ssi_dart from projects/KryptoOS/sdks/dart:

• DID method: did:kryptoos:empoorio:sr25519:*
• OuranoosUserCredential — ecosystem user identity commitment
• OuranoosProviderDeviceCredential — provider device attestation
• Sr25519Signature2026 proofs

Ouranoos service

lib/core/services/kryptoos_service.dart:

• Emits and verifies VCs locally
• getSsiStatus() returns:
  • SSI verificada — valid signed VC
  • Identidad local · fallback dev — local key without VC
  • Sin SSI · fallback dev — no SSI configured
• Device identifiers stored hashed, not in cleartext

On-chain identity commitment

pallet-storage-market stores ProviderIdentityCommitments — hash derived from DID + device VC + salt. No DID, email, or device ID in cleartext on-chain.

Status

Capability	State
Local VC issue/verify	REAL
UI distinction verified vs fallback	REAL
Remote KryptoOS issuance	PENDING
