Decentralized Education DAO

What it does:
Enables students, educators, institutions, and contributors to participate in governance and decision-making for educational initiatives on-chain.

Why it matters:
Promotes transparency, community-driven decision-making, fair resource allocation, and decentralized control over scholarships, courses, and educational funding.

How it works:

DAO issues governance tokens to students, educators, and contributors
Members propose initiatives such as course approvals, scholarship allocations, or platform upgrades
Token-weighted voting determines outcomes of proposals
Approved proposals automatically trigger on-chain actions (e.g., funding release, course creation)
Voting, proposal creation, and execution are recorded immutably
DAO can upgrade rules, treasury allocations, and membership criteria
Integrates with scholarship, micro-credential, and learn-to-earn contracts for seamless on-chain coordination
