ProofData Market

ProofData Market is a multilingual marketplace for publishing, discovering, licensing, and retrieving verifiable AI datasets on ShelbyNet.

Live application: proofdatamarket.vercel.app

Why ProofData

AI teams need more than a download link. They need to understand where data came from, what they may do with it, whether the published bytes are authentic, and how software agents can access it.

ProofData combines:

• Shelby-backed dataset publishing and cryptographic integrity
• Petra wallet connection on ShelbyNet
• ShelbyUSD pricing and license payments
• AES-256-GCM encrypted file delivery
• seller controls for price, metadata, and delisting
• provenance, collection dates, geography, language, and usage rights
• format-aware previews for images, text, CSV/TSV, JSON, audio, video, PDF, and archives
• reviews, reports, disputes, favorites, notifications, and activity history
• an agent-ready API for programmatic discovery and access
• nine interface languages, including Turkish, English, Spanish, Portuguese, Chinese, Korean, Japanese, Russian, and Arabic

Marketplace flow

1. A seller connects a Petra wallet configured for ShelbyNet.
2. The seller uploads a dataset, defines its price and license terms, and signs the publication.
3. ProofData encrypts the source file and publishes its Shelby commitment.
4. Buyers inspect a safe preview, provenance, rights, and integrity information.
5. A buyer pays the listed ShelbyUSD price and receives authorized access to the encrypted dataset.
6. The marketplace records verifiable activity without exposing the original file publicly.
