A decentralized autonomous organization is, at its core, an organization whose rules are enforced by software rather than by a manager or a board. Ethereum's own educational documentation describes DAOs as communities that coordinate through smart contracts—self-executing code that holds funds and carries out decisions—so that no single party can act unilaterally. What distinguishes one DAO from another is not the blockchain underneath but the governance model layered on top: who votes, how votes translate into action, and who ultimately presses the button that moves the treasury. Three patterns dominate—delegation, automatic transaction execution, and multisig signing—and each embodies a different trade-off between participation, speed, and trust.

How DAO Governance Models Work

The first question any DAO must answer is how proposals become decisions. Ethereum's documentation frames the choice as a set of considerations around "how voting and proposals work," and the models that emerge resolve those considerations in visibly different ways. The distinction matters in practice because it determines whether a DAO behaves like a direct democracy, a representative one, or something closer to a board-controlled trust.

Delegation is, in Ethereum's framing, "the DAO version of representative democracy." Token holders who do not want to follow every proposal can delegate their votes to members who nominate themselves and commit to stewarding the protocol and staying informed. The ENS DAO is the canonical example: ENS token holders can delegate their votes to engaged community members who represent them. The model buys informed decision-making at the price of concentrating influence in a professional class of delegates.

Automatic transaction governance removes the human execution step entirely. In many DAOs, transactions execute automatically once a quorum of members votes affirmative. Nouns DAO illustrates the pattern with a twist: a transaction is automatically executed if a quorum is met and a majority votes affirmative—as long as it is not vetoed by the founders. That veto clause is the tell. Pure automation maximizes trustlessness, but Nouns retains a founder check, showing how hybrid designs hedge against automated outcomes the founding team considers harmful.

Multisig governance takes the opposite approach to trust. Even a DAO with thousands of voting members may keep its funds in a shared wallet controlled by five to twenty active, trusted community members—typically people whose public identities are known to the community. After a community vote, these signers execute the will of the members. The model does not eliminate trust; it localizes it in a small, accountable group. Notably, the multisig pattern is primarily a mechanism for fund custody and execution rather than a complete governance system, and the available descriptions of it do not attach it to a single named DAO the way delegation attaches to ENS or automation to Nouns.
