Omron represents a significant stride in enhancing the Bittensor network, aiming to create the world's largest peer-to-peer Verified Intelligence network, by building a Proof-of-Inference system for the Bittensor network. This initiative aligns with the Opentensor foundation's criteria for innovative subnet solutions. zk-ML allows AI models to be converted into a unique 'fingerprint,' a circuit that can be used to verify that a model's prediction was generated by a specific AI model, thereby providing what we term as Proof-of-Inference.

Omron incentivizes miners and validators on Subnet 2 to contribute to the generation and validation of high-quality, secure, and efficient verified AI predictions using a specialized reward mechanism that aligns with the unique aspects of zero-knowledge machine learning (zk-ML) and decentralized AI. Currently Zero-knowledge proofs are generally more CPU computationally intensive and opens the opportunity for non-GPU miners to participate however the end goal is to further incentivize the development of proving systems optimized for GPU based operations. The incentives are based around Miners creating succinct and efficient models which can be circuitized with a zero-knowledge proving system.

The reward mechanism for Subnet 2 scores the initial AI predictions based on the cryptographic integrity and time to generate zk-proofs along with the outputs, rather than solely on end results. This approach reduces the computational burden on validators as zk-proofs confirm the source model and integrity of AI predictions efficiently.

• Receive input data from validators on the subnet.
• Generate predictions using custom, verifiable AI models that have been converted into zero knowledge circuits
• Return the generated content to the requesting validator for validation and distribution.

• Produce input data and distribute requests for verified inference throughout miners participating on the subnet
• Confirm that miners are acting faithfully, by verifying the authenticity of the miner's returned zero knowledge proof
• Score results from miners based on performance metrics such as proof size and response time

Miners contribute to this subnet by providing compute to generate output from, and prove AI model inferences. Miners receive workloads from validators in the form of input data, perform verified inferences on those inputs and respond with output along with a zero knowledge proof of inference.

Validators are responsible for verifying model outputs as provided by miners, and updating that miner's score based on the verification results.
