# Data Fabrication Challenge

> Miner-facing guide for Data Fabrication: submit dataset-generation harnesses, quality over volume.

Data Fabrication is a secondary challenge on BASE that rewards miners who generate useful **agentic coding conversation datasets**. You submit a complete dataset-generation harness. The challenge executes and reviews it, then rewards hotkeys that produce high-quality, diverse, verifiable, and original examples.

**Status:** Secondary / experimental relative to Agent Challenge and PRISM. Confirm live registry entry and emission share before large spends.

## What it is

| Item           | Detail                                                         |
| -------------- | -------------------------------------------------------------- |
| Slug (typical) | `data-fabrication`                                             |
| Artifact       | Dataset-generation harness (challenge-defined package)         |
| Success signal | Quality, diversity, verifiability, originality over raw volume |
| Evaluation     | Challenge-owned execution and review pipeline                  |

## Miner path

<Steps>
  <Step title="Register on BASE">
    Hotkey on netuid 100. See [Wallet and registration](/miners/wallet-registration).
  </Step>

  <Step title="Read the harness contract">
    Clone [`BaseIntelligence/data-fabrication`](https://github.com/BaseIntelligence/data-fabrication) and follow its miner README for entrypoints, allowed deps, and packaging.
  </Step>

  <Step title="Build for quality">
    Prefer verifiable and diverse conversation traces. Avoid trivial duplication and ungrounded synthetic soup.
  </Step>

  <Step title="Submit through the challenge">
    Use signed routes under `/challenges/data-fabrication/...` (or bridge upload if the live proxy documents it). Signing patterns: [Authentication](/miners/authentication).
  </Step>

  <Step title="Monitor review">
    Track challenge status and leaderboard. Accepted raw weights flow through BASE normalization like every other challenge.
  </Step>
</Steps>

## Costs and TEE

This challenge does **not** use the Agent Challenge Phala TDX self-deploy path. Cost model (CPU, storage, any external APIs the harness needs) is defined by the challenge and your harness; keep API secrets out of the public artifact when the contract forbids them.
