# Main Actors and Their Roles

**Orby** AI is built around a decentralized architecture of actors who interact through cryptographically verifiable logic on Ethereum. Each actor plays a distinct role in ensuring secure, scalable, and economically aligned AI execution — especially when models are tokenized as Real World Assets (RWAs).

**🧠 Inference Nodes (Executors)**

These nodes perform off-chain AI inference jobs using zk-compatible models. They are responsible for:

* Running the zk-circuit of a registered model.
* Generating zero-knowledge proofs for each inference.
* Submitting results + proofs for on-chain verification.

**RWA Link:** Executors power the usage metrics that trigger royalty distributions to RWA token holders. More executions = more revenue = higher yield.

**🧾 Validators**

Validators manage task coordination and proof verification logic:

* Dispatch inference jobs to available executors.
* Verify zk-proofs and enforce model authenticity.
* Submit validated results to Ethereum smart contracts.

**RWA Link:** Validators act as guardians of verifiability — their role ensures that only genuine, audited activity is used in RWA-related revenue contracts.

**📦 Ethereum Smart Contracts**

These are the on-chain programs that anchor **Orby** AI’s trust layer:

* Manage model registration, proof validation, scoring logic.
* Record logs, usage stats, performance scores immutably.
* Trigger payouts, slashing, or governance actions.

**RWA Link:** All smart contracts involved in inference, scoring, and payout are RWA-compatible — enabling models or agents to be financialized as income-bearing digital assets.

Each actor contributes to the decentralized intelligence fabric of **Orby** AI, ensuring that AI outputs are not only trustworthy but also economically meaningful — particularly in the emerging category of **AI-backed RWAs**.
