What SN21 is.
SN21 is the Bittensor subnet that continuously evaluates the AdTAO prediction engine. Miners produce predictions against outcomes that do not yet exist; validators score those predictions against ground truth once it settles; the chain pays for accuracy, not opinion. The site mirrors the canonical SN21 documents so they can be read, linked, and cited — the chain and the public repository remain the source of truth.
SN21 moved to a daily stream on 4 August 2026. Baskets of real account changes are now revealed daily rather than weekly, and outcomes settle at 7, 14 and 28 days. The weekly-era pages below remain published as the historical record of the mechanism that ran until 3 August 2026. The daily stream →

Weekly era, and protocol background.
Kept as the record of the mechanism that ran until 3 August 2026. The white paper's protocol sections still describe the system as built; its weekly-era sections are marked historical.
For miners.
Everything you need to submit a model is public. Start with how a miner joins, follow the quickstart command by command, and train on the published data. The public repository and the chain are the source of truth; the pages here mirror them.
- How a miner joins →
Register, train, containerise, commit the digest — the four steps, and where the data lives.
- Miner quickstart →
The step-by-step guide with every command, in the public repository.
- Training guide →
Join inputs to labels, train, export weights, and score yourself before you ship.
- Public repository →
Canonical docs, the published corpus under data/, and the training bundle on releases.
