Architecture

Ouranoos is the decentralized cloud layer of the Empoorio ecosystem — an alternative to Google Drive and AWS S3 where users buy cheap storage or sell device capacity under DMS/DUSD payments.

Production flow

archivo → cifrado local → chunking → provider descentralizado
       → deal on-chain → pago Eoonia → proof → retrieval → descifrado local

Client stack

Layer	Implementation
UI	Flutter (tabs: Inicio, Archivos, Mercado, Nodo, Base)
State	flutter_bloc — FilesCubit, NodeCubit, AuthCubit
Encryption	ClientEncryptionService, SecureFilePipelineService, MetadataEncryptionService
Storage	FileStorageService, DecentralizedStorageService, OuranoosProviderStorageService
Chain	EmpoorioChainService → empoorio_chain_sdk OuranoosService
Wallet	DeepLinkService ↔ Eoonia (eoonia://, ouranoos://)
Identity	KryptoosService → kryptoos_ssi_dart
Pricing	OuranoosPricingEngine, DracmaPricingService
AI	AiloosService — metadata-only by default, content opt-in

EmpoorioChain pallets

Cloud pallets in projects/EmpoorioChain/crates/emp-cloud:

• pallet-storage-market — providers, deals, reputation, SLA tiers
• pallet-storage-proof — periodic proofs, penalties
• pallet-file-contracts — file contracts
• pallet-cloud-allowance — DMS allowance and spend
• pallet-cloud-cdn — CDN tier providers

Replication policy

Initial policy: full-replica — encrypted packages pinned to N provider peers. CloudFile persists replicaProviderIds, requiredReplicas, availabilityScore, and estimatedMonthlyCostUsd.

State legend (walkthrough)

Status	Meaning
REAL	Implemented and covered by tests
BETA/LOCAL	Works on local/testnet, not public production network
PENDING	Requires integration before public beta

Quality gates

• flutter analyze — exit code 0
• flutter test — 26 tests including encryption, deep links, billing, SSI, observability
• No PII in structured logs (OuranoosLogger)

Pending before public beta

• Public IPFS/libp2p retrieval from external peers
• Full historical indexer for cloud and billing events
• Complete cryptographic proof validation on Base tab
• Android/iOS smoke with real Eoonia callbacks
