# NOVA Use Cases Demos

* **Healthcare: Verifiable Federated Learning Datasets** (<https://phala.com/success-stories/healthcare-research>), hospitals share encrypted records for federated learning without exposure. Hospital A uploads encrypted data to NOVA, Hospital B retrieves and process the data through Phala's TEE, it uploads the output data to NOVA. Hospital A retrieves Hospital B's output data, process it, and uploads the final output to NOVA.
* **Finance: Secure Portfolio Sharing Before TEE Risk Analysis** (<https://phala.com/success-stories/financial-services>): NOVA's group-keyed vaults store encrypted portfolios; TEE loads for private risk modeling (e.g., fraud detection), outputs back without leaks—ensures data sovereignty in multi-bank collaborations.
* **Law: Confidential Document Vaults Before TEE Review** (<https://phala.com/posts/confidential-ai-for-law-firms>): Upload sensitive legal docs to NOVA; TEE processes (e.g., AI contract analysis) without visibility; revoke access post-review—complements Phala's privacy for e-discovery.
* **Decentralized AI: Persistent Agent State for Multi-Chain Agents** (<https://phala.com/success-stories/decentralized-ai>): NOVA persists encrypted agent states/models between TEE sessions; enables multi-chain autonomy (e.g., cross-NEAR/Solana inference) with attestation chaining.
