Introduction
You've probably seen the word “DAO” go by in an article or on social media, usually wrapped in jargon. Behind the acronym sits a simple, powerful idea: letting people who don't know each other, scattered across the world, manage a project and a budget together — no boss, no headquarters, and no need to trust one another. How? By replacing bylaws and signatures with code that runs on its own. It's one of Ethereum's most original use cases, and you need to understand it to see where Web3 is heading.
The problem: collaborating with strangers
The internet lets you talk to anyone on the planet, but not manage money in common with just anyone. For that, you normally need a structure: an association, a company, bylaws, a joint account, signatories. And above all, you need to trust a few people who hold the keys. If the treasurer disappears with the cash box, all you have left is the courts.
A DAO — short for “decentralized autonomous organization” — attacks the problem differently: the organization's rules (who can propose, who can vote, how the money can be spent) are written in a smart contract on a blockchain. No more trusting a treasurer: nobody can spend the treasury without the group's approval, because the code quite simply forbids it.
An association whose bylaws enforce themselves
Imagine an association whose bylaws weren't a PDF tucked away in a drawer but a program: if 60% of members vote yes, the transfer goes out automatically; if not, it's impossible — even for the president. That's exactly the idea of a DAO: the bylaws AND their enforcement, fused into code.
A DAO is an organization with no rules — total anarchy.
Actually : It's the opposite. A DAO often has more rules than a traditional organization — and above all they're public, verifiable by anyone, and enforced automatically. What disappears isn't the rule: it's the need to trust the people who enforce it.
How it works: smart contract, treasury, voting
In practice, a DAO rests on three building blocks. First a smart contract (you can brush up on the concept in the Ethereum in depth module) that encodes the rules: once deployed, that code can no longer be quietly changed, not even by its creators. Then a treasury: a shared wallet, visible to everyone on the blockchain, that only a vote can unlock. Finally a voting mechanism: members make proposals, the group votes, and if the quorum is reached, the decision executes automatically — no trusted middleman.
That transparency changes the nature of the game: in a traditional organization, you discover the accounts once a year, summarized by the people who keep them. In a DAO, every expense, every vote and every rule is public, at all times, from day one. That's what lets strangers cooperate: they don't trust each other — they trust code they can all read.
- The smart contract encodes the rules: impossible to change them without a vote.
- The treasury is on-chain: nobody can spend it alone, everybody can audit it.
- Votes trigger execution: decision passed = action carried out, automatically.
Who decides? The three membership models
Not all DAOs govern themselves the same way. Three main membership models exist, each with its own logic and its own flaws. Knowing them lets you work out in seconds who really holds a given DAO.
- Token-based: holding the governance token gives you voting weight (often 1 token = 1 vote). Open to everyone, but whoever buys a lot of tokens carries a lot of weight.
- Share-based: you apply, you bring a contribution, and the group votes on your admission. More closed, closer to a cooperative.
- Reputation-based: voting weight is earned by participating; it can be neither bought nor transferred. More resistant to money, but slower to build.
Delegation, or Web3's representative democracy
In big DAOs, voting on everything becomes a full-time job. Many therefore adopt delegation: you entrust your voting power to an active member whose vision you share, and you can take it back at any time. It's the model chosen by ENS, Ethereum's name service.
Real-world examples
DAOs aren't a theory: some have been managing treasuries worth hundreds of millions of euros for years. MakerDAO governs the decentralized stablecoin DAI: holders of the MKR token vote on the protocol's risk parameters. ENS, Ethereum's “directory service”, is governed by its community through vote delegation. Nouns funds creative projects with one NFT sale per day, whose proceeds feed a shared treasury. And CityDAO even used a law in the state of Wyoming, which legally recognizes DAOs, to buy a very real plot of land.
What these examples show: a DAO can govern a financial protocol, an infrastructure service, an art project or a real-estate purchase. The common thread isn't the field — it's the method: collective, transparent decisions, executed by code.
The limits (because there are some)
Be clear-eyed: governance by code hasn't abolished power dynamics. In token-based DAOs, a handful of large holders — the famous whales — can outweigh thousands of small voters. Participation is often low: many holders never vote, which makes it easier for an organized minority to take control. And genuine governance attacks exist: borrowing a voting token massively just long enough to push through a proposal that drains the treasury has already happened.
Add two structural weaknesses: if the smart contract has a bug, the buggy rules apply anyway (code has no conscience), and the legal status of DAOs remains murky in most countries — in a dispute, you're flying blind. In short: a badly designed or badly governed DAO can lose its members' money, exactly like a badly run traditional organization.
Before joining or voting: DYOR
Who holds the governance tokens? What's the actual voter turnout? Has the code been audited? Is the treasury diversified? Those are the questions from the DYOR: doing your own research module — and they apply to DAOs word for word.
The governance token of a well-known DAO is bound to gain value.
Actually : A governance token is a voting right, not a promise of gains. Its price depends on supply and demand, and it can fall even if the DAO is doing well. Never confuse “interesting project” with “guaranteed investment”.
What it changes for you
Even if you never join a DAO, this model concerns you: some of the protocols you'll come across in DeFi (decentralized exchanges, lending protocols like the ones in the Yield, staking & DeFi module) are governed by DAOs. Understanding who votes and how means understanding who really controls the tools you use — and that's a core skill of an independent investor.
And the next time someone mentions a “governance token”, you'll know which questions to ask: governance of what, held by whom, with what participation? That's exactly the kind of clear-headedness that separates a considered purchase from an impulsive one.

- 01A DAO is an organization whose rules, treasury and votes live in a smart contract: collective decisions, automatic execution.
- 02You don't trust the leaders — you trust public code that anyone can verify.
- 03Three membership models: token-based (open but whale-sensitive), share-based (cooperative-style), reputation-based (can't be bought).
- 04The limits are real: concentrated voting power, low participation, governance attacks, legal grey areas.
- 05A governance token is a voting right, not a promise of gains.
