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 Hubic 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 HUB (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 HUB):

• 60 HUB → model owner (or RWA smart contract)

• 20 HUB → executor

• 20 HUB → 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.
