Why Trust When You Can Verify?
Omron Subnet (SN2) pioneers decentralized AI, hosting a leading zkML (Zero-Knowledge Machine Learning) proving cluster for scalable, verifiable computing. Built on decentralized value creation and aligned incentives within Bittensor, SN2 exemplifies the transformative potential of zkML. This report explores its significance and technological foundations.
Zero-Knowledge Proofs (ZKPs) Demystified
Analogous Example:
Imagine playing "Where’s Waldo?" where Bob proves he knows Waldo’s location without revealing it. He uses a cardboard sheet with a small hole to isolate Waldo, demonstrating knowledge without disclosure.
Technical Underpinnings:
ZKPs leverage elliptic curve cryptography, polynomial commitments, and arithmetic circuits. These circuits break computations into simple operations (e.g., addition/multiplication). Provers encode secrets into the circuit, generating proofs verifiable without exposing raw data. This ensures both privacy and computational efficiency.
zkRollups: Blockchain Scalability Unleashed
ZKPs enable rollups (e.g., StarkNet, zkSync) to validate transactions off-chain, submitting only proofs to the blockchain. This reduces Ethereum’s 15 TPS limit to 2,000+ TPS, slashing costs by 100x. Key benefits:
- Speed: Near-instant verification.
- Cost: Fractional transaction fees.
- Security: Cryptographic guarantees.

zkML: The Holy Grail of Decentralized AI
Combining ZKPs with machine learning (zkML) enables:
- Verifiable AI: Users confirm model integrity without accessing proprietary data.
- Privacy-Preserving Inference: Service providers run models locally while proving correctness via zk proofs.
- On-Chain Feasibility: Offloads heavy ML computations to zk proofs, bypassing blockchain constraints.
State-of-the-Art Progress:
Recent advancements reduced MNIST dataset proofs from 100GB/30min to <1GB/2sec, even for models with hundreds of millions of parameters. Projections suggest zkML could match traditional ML performance by 2025.
SN2’s Role in Advancing zkML
Bittensor’s Omron Subnet (SN2) incentivizes miners to optimize zk proof generation. Innovations include:
- Hardware Tuning: Miners refine CPUs and FPGAs to cut proof times (e.g., LSTM proofs from 15sec → 5sec).
Use Cases:
- Training Proofs: Verify model training adherence.
- Inference Proofs: Ensure correct model usage during service requests.
Cross-Chain Compatibility:
SN2 proofs verify on EVM-compatible blockchains, enabling secure on-chain inference bridging. Example: Ethereum proof-of-concept verification.
Future Roadmap: Version 2 Updates
- zk Circuit Competitions: Miners compete to optimize proof speed, size, and model accuracy.
- Enterprise Integration: Validators host custom zkML challenges for external clients.
Proof of Weights: Enhancing Bittensor’s Ecosystem
Omron introduces Proof of Weights (PoW), a ZK-based mechanism to ensure validator transparency. Features:
- zk Circuits for Scoring: Validator weights calculated via ZKPs (using Circom/JOLT zkVM).
- Network-Wide Adoption: Open-source SDKs facilitate PoW integration across Bittensor subnets.
- BIT Initiative: Aims to embed PoW into Bittensor’s core for decentralized governance.
