CrunchDAO

CrunchDAO is a decentralized AI research community that connects data scientists with institutions through prediction competitions (Crunches). Institutions publish real-world problems, and over 11,000 ML engineers and 1,200 PhDs worldwide build models. The system automatically evaluates submissions and distributes USDC rewards.

Its core competitiveness lies in lowering participation barriers: researchers can submit models without blockchain knowledge, data remains private through Trusted Execution Environments (TEE), and model aggregation improves accuracy. The platform runs on Bittensor subnets and uses the CFI index to help researchers choose suitable competitions, addressing issues like data silos, limited perspectives of internal teams, and lack of resources for independent researchers.

In the past six months (March to September 2026), the platform iterated continuously: fixed submission issues for users in China, added a GPU request mechanism (submissions not requiring GPU must request access), and now displays real-time metrics and durations. New competitions like broad-obesity-3 and numinous were launched, with numinous rewarding only the signal track. Additionally, the CFI index was introduced on Bittensor, combining task fit, profitability, competition density, etc., to help researchers efficiently select subnets. These updates improved usability and transparency, but GPU resource limits and adjustments to some competition rewards also sparked discussions.
