What is the biggest DAO?

Might I inquire about the largest Decentralized Autonomous Organization, or DAO, that currently exists? I'm keen on understanding its scale, its influence, and how it compares to other players in the cryptosphere. Could you please elaborate on its core features, membership, and perhaps even its impact on the broader cryptocurrency and finance landscape? I'm particularly interested in how it functions, its governance structure, and any notable achievements it may have made. Your insights would be greatly appreciated.
