Tokens in a DAO, often referred to as governance tokens, serve multiple purposes. Primarily, they represent a member's voting rights within the DAO. The number of tokens a member holds often determines the weight of their vote on matters concerning the DAO's governance. Secondly, they can also provide financial incentives for token holders, either through rewards or through the appreciation of the token's value. However, the specific functionality of tokens can vary significantly between different DAOs.
