# Orby AI Hub – Model Registry

The **Orby AI Hub** is a permissionless registry of zk-compatible AI models. Deployed fully on-chain via Ethereum smart contracts, it serves as the trust anchor for all inference activity and monetization across the network.

Each registered model is:

* Identified by a unique zk-circuit hash.
* Associated with metadata (version, type, zk format, usage fee).
* Linked to a public verification key and on-chain logic.

This registry enables transparent usage tracking, RWA tokenization, and composability across Ethereum-based DAOs, DeFi protocols, and dApps.

**📄 Sample Fields:**

| Field           | Description                                       |
| --------------- | ------------------------------------------------- |
| `Name`          | Human-readable label (e.g., “Yield Optimizer v1”) |
| `Type`          | Model classification: Strategy, Agent, Scoring    |
| `zk Hash`       | SHA-256 hash of the compiled zk-circuit           |
| `Version`       | Compatible inference versioning (e.g., v1.1)      |
| `zk Format`     | Halo2, Risc0, zkWASM, etc.                        |
| `Fee`           | Execution cost per inference                      |
| `Verifier ID`   | Linked verification contract address              |
| `Royalty Split` | On-chain percentage flow to model stakeholders    |
| `RWA Token ID`  | (optional) ERC-20/NFT representing model shares   |

| **Orby**-KYC  | Identity Agent  | ✅           | v0.9    | `0xdef456` | zk-KYC for RWA access control |
| **Orby**-RWAx | Revenue Model   | ✅           | v1.0    | `0x0f0f0f` | Tokenized AI inference engine |
| **Orby**-Gov  | DAO Coordinator | ✅           | v2.1    | `0xghi789` | Governance Proposal Generator |

**🌍 RWA Integration:**

Models registered in the **Orby** AI Hub can:

* Be fractionalized and represented as ERC-20/NFT tokens.
* Distribute yield from verified usage to token holders.
* Maintain public audit trails for inference history and royalty claims.
* Enable DAO-managed model ownership, upgrades, or retirement through governance.

This registry is the **foundation for real-world assetization of AI compute**, transforming inference models into trackable, monetizable primitives on Ethereum.
