Monetize Open-Weight AI Models: A Protocol for Automated Royalty Payments
A proposed blockchain-based system tracks API usage of open-source models to split revenue between creators, fine-tuners, and data providers, enabling a new monetization layer.
Practical Summary
For AI developers and infrastructure providers, this outlines a workflow to generate ongoing revenue from open-weight models by cryptographically tracking and billing for each API inference, with automated daily settlements.
Why It Matters
Open-weight models are often freely distributed, leaving creators with no direct revenue from downstream commercial use. This protocol offers a viable, enforceable method to capture value from inference, turning a one-time release into a sustainable income stream aligned with usage.
How the Open-Weight Royalty Protocol Works
The system is designed to automatically track and pay royalties when commercial APIs use your open-weight model. Here is the proposed workflow:
Step 1: License and Anchor Your Model Weights
The process begins by creating a unique hash of your model's weights. This hash is anchored on a blockchain (like an L2 network) along with a smart contract that defines the revenue split percentages—for example, 60% to the original creator, 25% to a fine-tuner, and 15% to data donors.
Step 2: Track Inference with Cryptographic Receipts
When a service provider runs inference using your model, both the client and the provider sign a digital receipt. This receipt contains the weight hash, endpoint ID, a unique nonce, timestamp, and the number of compute units used. This creates a verifiable proof of service delivery.
Step 3: Ensure Trust with Secure Hardware
To prevent fraud, the system prioritizes using Trusted Execution Environments (TEEs) like Intel SGX or AMD SEV-SNP. Inside this secure hardware, the request and response data are hashed and signed, binding the inference to the specific model and preventing tampering.
