Web3 Student Lab 🎓⛓️

Web3 Student Lab is an open-source educational platform that helps students learn blockchain, smart contracts, open-source collaboration, and hackathon project development in one place.

The platform provides interactive tools, coding environments, and guided learning paths designed for beginners and university students.

🟢 Live Deployment

The application is fully deployed and accessible online:

• Frontend Application: https://web3-student-lab.vercel.app/
• Backend Infrastructure: Hosted securely on Render using PostgreSQL, Redis, and integrated with the Stellar/Soroban Testnet.
• Smart Contracts: My contract is deployed!

🚀 Core Modules

1. Blockchain Learning Simulator: Visually learn how blockchains work (create transactions, mine blocks, view hashes, and see how blocks connect).
2. Smart Contract Playground: Write, run, and test smart contracts directly in your browser. Focuses on Soroban contracts written in Rust.
3. Web3 Learning Roadmap: A guided path spanning programming fundamentals, cryptography, blockchain architecture, smart contracts, and full Web3 applications.
4. Hackathon Project Idea Generator: Overcome coder's block by generating ideas based on technology and sector preferences.
5. Open Source Contribution Trainer: Get hands-on with Git, simulated GitHub issues, PR exercises, and decentralized identity verification that attaches DID-backed contributor proof to saved training submissions.

👥 Local Development

Prerequisites

• Node.js (v18+)
• Docker and Docker Compose (for PostgreSQL/Redis)
• Rust toolchain (for smart contracts)
• Stellar CLI

Infrastructure (Docker Compose)

Most day-to-day work only needs PostgreSQL + standalone Redis. Prefer the development override so Sentinel and Cluster nodes are not started:

# Recommended for development (PostgreSQL + standalone Redis only)
docker compose -f docker-compose.yml -f docker-compose.dev.yml up -d

Other compose profiles:

# Full stack (PostgreSQL, Redis, Sentinels, Cluster, backend) — production-like testing
docker compose -f docker-compose.yml up -d

# High-availability Redis testing (Sentinel / Cluster wired for the backend)
docker compose -f docker-compose.yml -f docker-compose.prod.yml up -d

File	Purpose
docker-compose.yml	Full stack: Postgres, Redis, Sentinels, Cluster, backend
docker-compose.dev.yml	Dev override: Postgres + standalone Redis only
docker-compose.prod.yml	HA override: Sentinel/Cluster-oriented backend config

Stop services with docker compose down (pass the same -f flags you used to start).

🔐 MVP Update: Decentralized Identity Verification

The Open Source Contribution Trainer now includes decentralized identity verification for contributor workflows in frontend/src/app/version-control/page.tsx.

• Contributors link a DID, Stellar wallet address, and GitHub handle before saving a verified trainer version.
• Verified saves persist proof metadata in the version history engine at frontend/src/lib/version-control/engine.ts.
• Core attestation creation and verification logic lives in frontend/src/lib/open-source-trainer/identity.ts.
