[Auth & Identity] Implement GitHub & Discord OAuth Proof Binding to Stellar Public Keys

[ayomideadeniran]

🚀 Feature Overview

Allow students to link verified Web2 social identities to their on-chain Stellar public keys for hackathon team verification and leaderboards.

🛠️ Implementation Requirements

* Implement OAuth 2.0 PKCE flow for GitHub and Discord with secure Redis state nonces.
* Generate cryptographic link attestation signed by both OAuth identity and Stellar keypair.
* Store public identity mappings in decentralized DID registry contract.
* Expose verified social badge components across student profiles and forum discussions.

🔧 Technical Specifications

* TypeScript, Stellar SDK, SEP-0010, WebCrypto, Redis, JWT

✅ Acceptance Criteria

* Student profiles display cryptographically verified GitHub and Discord identity badges.
* OAuth state nonce validation strictly prevents CSRF and code injection exploits.
* Decentralized DID registry resolves linked social handles on-chain.

🎓 Difficulty Level

* Hard - Stellar transaction envelopes, cryptographic signature verification, and session state

⏱️ Timeline

* ETA: 4-5 days
