# Rewards & Settlement

Once an inference is successfully verified on-chain, the **Settlement Contract** is triggered. It performs **deterministic, on-chain payment distribution** to all involved parties — model owner, executor, and verifier — using the original inference fee submitted by the user.

This step guarantees that only **cryptographically proven computation is paid**, forming the economic foundation of both Orby AI and any tokenized RWA model.

***

**💰 Default Distribution Breakdown (Per Inference):**

| Role        | Share   | Notes                                        |
| ----------- | ------- | -------------------------------------------- |
| Model Owner | **60%** | Can be a wallet or RWA token contract        |
| Executor    | **20%** | Paid for zk-inference and proof generation   |
| Verifier    | **20%** | Paid for validating the zk-proof on Ethereum |

**⚙️ Settlement Logic Flow:**

1. Verifier contract emits a `VerifiedInference` event.
2. Settlement contract reads the associated payment data from the original request.
3. It distributes the $ORBY (or USDC/ETH if multi-token enabled) to:
   * Registered model owner address
   * Executor wallet
   * Verifier node
4. Emits `InferenceSettled` log with all payment receipts.

***

**🧾 Example Payout (Job = 100 $ORBY):**

* `60 $ORBY` → model owner (or RWA smart contract)
* `20 $ORBY` → executor
* `20 $ORBY` → verifier

All payments are atomic and final.

***

**⛓ On-Chain Record:**

Every settlement is stored immutably and indexed by:

* `request_id`
* `model_hash`
* `payer`
* `timestamp`
* payout recipients + values

This ensures compatibility with reputation scoring, DAO transparency, and RWA audit/reporting layers.

**🌍 RWA Integration:**

* **Auto-Streaming to RWA Holders:** Model owners can register an ERC-20 or ERC-721 payout contract that distributes revenue to token holders (e.g., via Superfluid or streaming vaults).
* **Performance-Linked Yield:** RWA dashboards can show real-time yield generated by model usage and task volume.
* **Composable Revenue Sharing:** Smart contracts can split model owner fees across DAOs, LPs, dev teams, or token holders.

> Settlement turns AI into an income-generating asset — where math, not trust, guarantees payment.
