DataMinder DeSci Platform

Context: Masterz Solana Bootcamp

Developed as the Final Capstone Project for the Masterz Blockchain Bootcamp. The project was built by a team of 3 developers to solve the issue of data centralization in scientific research.

Project Mission

DataMinder is a Decentralized Science (DeSci) platform that aims to return data ownership to individuals[cite: 506]. In the current landscape, research institutions hoard sensitive data in silos. DataMinder allows users (e.g., patients) to store their data securely and grant access to researchers only upon payment and consent[cite: 510].

How it Works: The “Encrypted NFT” Logic

The core innovation lies in how data is handled on the Solana blockchain:

1. Encryption: Sensitive data is encrypted client-side using the user’s keys.
2. NFT Minting: The encrypted data is stored as metadata within an NFT[cite: 522].
3. Access Control: When a researcher purchases access, the data is re-encrypted using their public key (Asymmetric Encryption), allowing them—and only them—to read it[cite: 524, 528].

MVP Features

The platform demonstrates a complete user flow:

• Wallet Connection: Authentication via Solana wallets[cite: 583].
• Data Upload: Users upload documents which are minted as private NFTs[cite: 586].
• Marketplace: An “Explore” page where researchers can browse available (but encrypted) datasets[cite: 587].
• Request System: Researchers send access requests, and users approve them to release the decryption keys[cite: 588].
