Train AI. Earn Crypto. Save Costs A decentralized AI training network that uses idle GPUs from personal devices to train models in parallel. Devices process small training and merge them in a server.
The problem TrainChain solves
- Millions of GPUs in laptops, PCs, and phones are idle most of the time.
- There is a growing demand for faster, cheaper, and greener AI training solutions.
- High AI training costs limit access for small developers and startups.
- Centralized AI training requires expensive infrastructure and consumes significant energy.
- Users currently have no easy way to earn from their device’s unused computing power.
Challenges we ran into
🧩 Task Distribution & Coordination
- Splitting large models and datasets across multiple GPUs efficiently was complex.
- Ensuring synchronization and consistency in training results was a major challenge.
✅ Trust & Verification
- Verifying that participants actually performed the assigned computation (and did it correctly) required designing a lightweight yet reliable proof system.
🔒 Security & Data Privacy
- Training AI on sensitive data required us to consider privacy-preserving methods like federated learning and secure aggregation.
🌐 Network Latency & Fault Tolerance
- Since we're working with distributed nodes over the internet, managing delays and handling node failures without interrupting training was a tricky part.
🎯 Incentive Mechanism
- Designing a fair and motivating reward system that balances contribution with quality was a challenge, especially without a full blockchain integration.
⏳ Limited Time & Resources
- Being a hackathon project, implementing the complete system in a short timeframe with limited infrastructure was tough, so we prioritized building a functional MVP.
