Project: Proof-of-Peer – Learning Credentials via Soulbound NFTs

Category: Identity / Education / Reputation

Difficulty: Beginner – Intermediate

🧠 Core Idea:

Design a platform that issues soulbound NFTs (non-transferable tokens) to learners for completing online courses, tutorials, workshops, or contributing to open source. Allow peer endorsements and skill ratings directly on-chain. Could also link to GitHub repos or Gitcoin badges.

🛠️ Tech Stack Ideas:

• Smart Contracts: ERC-721 + ERC-5484 (soulbound spec)
• Frontend: React + Ethers.js or Wagmi
• Storage: Arweave or IPFS for badge metadata
• Infra: Linea, Zora, or Base for NFT minting at low cost

🗃️ Data Sources:

• Simulated course completion data (from MOOCs, workshops)
• Open certification providers (Coursera, edX) APIs (if used off-chain)
• GitHub profile stats, pull request logs

🧩 Bonus Ideas:

• Skill trees that evolve: NFTs level up based on streaks
• Indian twist: “Certified ChaiCoder,” “React Rani,” “SQL Shera” etc.
• DAO voting for peer-review based endorsements
