Governance token voting is a blockchain-based system where token holders vote on protocol changes, funding decisions, and strategic direction. Each proposal is submitted (change fee prevents spam), debated, voted on (usually 3-7 day voting period), and executed if passed (majority or supermajority required). Key concepts: (1) Token = voting power, (2) Proposals = changes to protocol/treasury, (3) Voting contracts = Solidity code enforcing voting rules, (4) Delegation = token holders delegate voting power to trusted entities, (5) Snapshots = historical block to measure voting power (prevents flash loan attacks).
