TL;DR
A DAO is an organization governed by token holders through on-chain voting, where proposals and decisions are executed by smart contracts instead of a traditional management hierarchy.
Token holders submit proposals (e.g., change a protocol parameter, fund a grant, hire a contributor) and vote using their governance tokens. If the vote passes quorum and approval thresholds, the proposal is executed — often automatically through on-chain governance programs. This creates transparent, democratic decision-making where every vote is publicly verifiable on the blockchain.
Realms is Solana’s primary governance platform (built by Solana Labs). Major Solana DAOs include Jupiter DAO (JUP governance), Marinade DAO (mSOL staking decisions), and various protocol treasuries. SPL Governance is the underlying program that handles proposal creation, voting, and execution. Some DAOs use token-weighted voting; others use conviction voting or quadratic voting for fairness.
Hold the governance token, connect to the DAO’s voting platform (usually Realms), and vote on active proposals. Some DAOs require staking or locking tokens to vote, giving more weight to committed holders. Active governance participation can earn rewards in some protocols. Even if you don’t vote, understanding a project’s governance structure tells you who controls it and how it can change.
