What is a DAO, and how does it work?

A plain English guide to decentralised autonomous organisations: how DAOs work, how decisions get made, and what the risks are for UK investors.

An organisation with no CEO, no office, and no employees making decisions. Instead, a set of rules written into code and a community of token holders with a vote. That is the promise of a DAO, and it sounds straightforward enough until you look at how it actually plays out in practice.

The Short Version

A DAO (decentralised autonomous organisation) is an organisation governed by rules encoded in smart contracts on a blockchain, rather than by a board of directors or management team. Members hold governance tokens that give them voting rights on decisions, from how to spend a shared treasury to what parameters the protocol should run on.

There is no CEO or central authority. Rules are written into code.
Governance token holders vote on proposals. More tokens generally means more voting power.
Approved decisions are executed automatically by smart contracts, without human sign-off.
DAOs exist in a legal grey area in the UK and most other jurisdictions.
The largest DAOs collectively control tens of billions of dollars in assets.

Where the Idea Came From

The concept of a DAO emerged from the same community that built Ethereum. The logic was straightforward: if you can write financial contracts in code, why not write the rules of an entire organisation in code too? If those rules live on a blockchain, no single person can secretly change them, override them, or be bribed into ignoring them. The organisation would simply run, automatically, according to its own bylaws.

The term DAO first entered the mainstream in 2016 when a project called “The DAO” raised around $150 million in ether on Ethereum. Within months, a hacker exploited a flaw in the smart contract code and drained roughly $60 million, forcing the network to conduct a controversial hard fork to recover the funds. The lesson was stark: if the code is the law, a flaw in the code is a flaw in the legal system, with no court to appeal to.

Despite that beginning, the concept survived and matured. Today, major DeFi protocols including MakerDAO, Uniswap, and Compound operate under DAO governance.

How a DAO Makes Decisions

The mechanics follow a broadly similar pattern across most protocols, though the details vary considerably.

A community member holding enough governance tokens submits a proposal, for example: “Allocate 500,000 USDC from the treasury to fund a security audit.” That proposal goes live on the DAO’s governance platform, either on Snapshot (off-chain, no gas fees) or directly on-chain through the protocol’s voting contracts.

Token holders then vote. In the most common model, each token is one vote, giving larger holders proportionally more weight. Some DAOs use modified systems, such as quadratic voting (reducing the power of very large holders) or delegated voting, where token holders assign their vote to a trusted representative.

If the vote crosses a set threshold, often a simple majority, sometimes a supermajority, the decision is executed automatically through a smart contract. No board needs to convene. No executive needs to countersign. The outcome is written to the blockchain and takes effect.

Governance Tokens: What They Are and Why They Matter

Governance tokens are what transform an ordinary holder into a participant. They are blockchain tokens, typically ERC-20 tokens on Ethereum, that carry voting rights within a specific protocol or organisation.

MKR is the governance token of MakerDAO: holders vote on interest rates, collateral types, and the risk parameters that keep the system solvent. UNI governs Uniswap, giving holders a say on fee structures, protocol upgrades, and treasury spending. COMP governs Compound, one of the earliest DeFi lending protocols.

The value of a governance token is partly speculative and partly linked to the health of the underlying protocol. If MakerDAO’s decisions lead to DAI growing in usage and trust, MKR may increase in value. But the relationship is loose. Governance tokens have consistently been among the most volatile assets in the crypto market, and many have lost the majority of their value even as the protocols they govern have continued to function normally.

Governance tokens are often distributed to early users through airdrops, or earned by participating in the protocol, such as by providing liquidity. This has made some early users substantial sums and attracted regulatory scrutiny in several jurisdictions.

The Problems DAOs Have Struggled With

The theory of decentralised governance sounds elegant. The practice has been considerably messier.

Voter apathy is the most persistent problem. Only a small fraction of token holders ever vote on proposals across most protocols. The majority sit in wallets whose owners have no intention of participating. Despite the decentralisation rhetoric, decisions are effectively made by a small group of engaged participants and the largest token holders.

Plutocracy follows directly from the one-token-one-vote model. The wealthiest holders have the most influence. Many DAOs launched with the promise of being more democratic and community-led, but the reality, when venture capital funds with large token allocations cast decisive votes on protocol parameters, has often looked quite different.

Smart contract risk remains serious. If the code governing a DAO has a vulnerability, it can be exploited, as the 2016 DAO hack demonstrated. There is no insurance and no regulator to intervene. Users have lost significant sums to governance exploits and smart contract failures.

Legal ambiguity is an unresolved problem in most countries, including the UK. If a DAO causes financial harm, there is no clear framework for liability or redress. In Wyoming, DAOs can formally register as LLCs, but no equivalent framework exists in the UK. Participants could, in theory, find themselves personally liable for the DAO’s actions, though this has not been tested extensively in British courts.

A Worked Example

MakerDAO provides the clearest illustration of how governance works under pressure.

MakerDAO oversees DAI, a stablecoin designed to hold a $1 value by being backed by collateral locked in smart contracts. MKR holders vote on the parameters that keep this system stable: which assets can be used as collateral, how much collateral is required relative to the amount of DAI issued, and what interest rate borrowers pay.

In March 2020, the pandemic triggered a sharp collapse in crypto prices. ETH fell so fast that some collateral positions became undercollateralised before the system’s liquidation mechanisms could act. MakerDAO ended up with a deficit of around $4 million between its collateral value and the DAI issued.

The response ran entirely through governance. MKR holders voted to issue new MKR tokens and sell them at auction to cover the shortfall. This diluted existing MKR holders but preserved the integrity of DAI. The decision was debated, voted on, and executed in days. There was no board meeting and no government bail-out. The community decided, and the code executed the outcome.

What This Means For You

If you hold governance tokens, you hold a vote. Votes only have value if you use them, and most retail holders do not, which means the direction of major protocols is largely set by a small number of engaged participants and large institutional holders. Understanding this reality matters before you treat governance token ownership as equivalent to democratic participation.

If you are considering buying governance tokens as an investment, be aware that their value is not straightforwardly tied to a protocol’s growth. Many governance tokens have fallen sharply in price even as the underlying protocol continued to expand. They are speculative assets, and they carry an additional risk that a governance attack, where a large holder or coordinated group pushes through a self-serving proposal, could damage both the protocol and the token’s value simultaneously.

For UK investors, the absence of a legal framework means there is no consumer protection if a DAO you participate in suffers a hack, a governance failure, or simply makes decisions that harm its users. That is a material difference from the protections of a UK-regulated investment fund.

In Plain English

A DAO is an organisation that runs on code instead of managers. Governance token holders vote on decisions, from how money is spent to what rules the organisation follows. No single person is in charge, at least in principle. In practice, DAOs are often heavily influenced by their largest token holders, and carry real risks: smart contract vulnerabilities, legal uncertainty, voter apathy, and governance attacks. Understanding how they work matters whether you are evaluating a governance token as an investment, using DeFi protocols, or making sense of how a growing part of the crypto economy operates.
