Decentralized Autonomous Organizations (DAOs) are digital entities governed by smart contracts and decentralized decision-making processes, enabling autonomous operations and community governance without centralized control. DAOs allow participants to propose, vote on, and fund projects, manage resources, and govern decentralized networks transparently and democratically. DAOs are used in various sectors, including decentralized finance (DeFi), governance tokens, and community-driven initiatives, promoting innovation, transparency, and participatory decision-making in the blockchain ecosystem. Projects like DAOstack and Aragon are advancing DAO infrastructure and governance models for scalable and inclusive decentralized organizations.
