DAO
A DAO (decentralized autonomous organization) is a form of organization in which decisions are coordinated by members or token holders, with rules and funds managed partly or fully by smart contracts instead of a traditional management hierarchy.
How a DAO works
A DAO usually has three parts. A membership or voting system, often based on governance tokens or NFTs. A set of smart contracts that hold funds and enforce certain rules. And a process for proposals, discussion and votes. When a proposal passes, contracts may execute it automatically, or a group of signers holding a multisig wallet carries it out.
In practice, few DAOs are fully autonomous. Most combine on-chain votes with forums, core teams, legal entities and trusted signers.
What DAOs are used for
The most common use is governing DeFi protocols, where token holders vote on parameters and treasury spending. Others pool money to fund grants, invest together, buy collectibles, or run communities and media projects. The appeal is transparent rules and a treasury anyone can inspect on-chain.
A famous lesson: The DAO
In 2016, a project called The DAO raised a large amount of ether to act as a community-run investment fund. In June 2016, an attacker exploited a flaw in its smart contract and drained about 3.6 million ETH. The Ethereum community responded with a hard fork that returned the funds; those who rejected the fork kept the original chain, which became Ethereum Classic. The episode showed that code can contain costly bugs and that decentralized governance can face hard choices.
Risks and limits
Smart contract bugs can expose the treasury. Voting power is often concentrated, and turnout is low. Governance attacks, for instance borrowing tokens to swing a vote, are possible without safeguards. Legal status is unclear in many countries; in some cases, members of a DAO without a legal wrapper may face personal liability. Decisions can also be slow compared with a company.

Frequently asked questions
Is a DAO a company?
Not necessarily. Some DAOs set up legal entities such as foundations or LLCs; others have no legal form, which can create liability questions for members.
How do I join a DAO?
Usually by acquiring its governance token or membership NFT, then taking part in forums and votes. Rules differ for each DAO.
Who controls a DAO's money?
Funds sit in smart contracts or multisig wallets. Who can actually move them depends on the contract design and the signers.
