# Nubila Oracle Architecture

####  Collection Layer

* Marco Stations – Compact, solar-powered weather & environmental devices deployed globally.
* Signals Captured – Temperature, humidity, wind speed, air quality, solar radiation, and more.
* Geo-Grids & CIDs – Data is structured into geo-grids and packaged into content identifiers for traceability.

#### Validation Layer

* Validator Nodes – Recompute CIDs, check device signatures, and run anomaly detection.
* Consensus – Quorum-based validation ensures no single actor can alter results.
* Anchoring – Verified signals are anchored on-chain (via Monad) for settlement-grade performance.

#### Storage Layer

* Hot Storage – Low-latency access for live oracle feeds.
* Cold Storage – Long-term archives for AI model training, compliance, and auditing.
* Distributed Systems – NilDB for encrypted, privacy-preserving storage; IPFS/Arweave for redundancy and immutability.

#### Application & Oracle Layer

* APIs & Dashboards – Provide real-time and historical access for developers and enterprises.
* Programmable Feeds – Tokenized RWA data streams usable across DeFi and AI ecosystems.
* Cross-Chain Oracles – Interoperable feeds for multi-chain financial protocols.

####  Integration & Functionality

* Enterprise-Grade Reliability – SLAs for data latency and uptime.
* AI Readiness – Pre-structured data formats for ML pipelines.
* Web2 ↔ Web3 Bridge – Seamless integration into both enterprise and decentralized systems.<br>
