NOVA for Decentralized AI: Persistent Agent State for Multi-Chain Agents

NOVA persists encrypted agent states/models between TEE sessions; enables multi-chain autonomy (e.g., cross-NEAR/Solana inference) with attestation chaining.

Use Case

In AI training (e.g., Phala's success story: (https://phala.com/success-stories/decentralized-ai))

How NOVA Complements Private ML SDK

Phala focuses on runtime privacy ("no storage, no logs"); NOVA adds decentralized persistence: encrypt/upload via composite_upload, retrieve into TEE, output back. Focus: Data pipeline security without reinventing Phala's compute. NOVA handles pre-enclave sourcing (group auth) and post-enclave auditing (on-chain hashes/CIDs), extending Phala's quotes for full-lifecycle verifiability.

Running the Demos

• Set .env (NEAR_PRIVATE_KEY, etc.).

• Rust: cargo run --bin tee_federated_learning.

• JS: ts-node demos/tee_federated_learning.ts.
