Circles run in Epochs: periods in which constituent contributors can send each other GIVE tokens, representing that Circle's total budget allocation. We envision Epochs as monthly events where contributors can consider each other's collaboration, mutual enablement, and furthering of the DAO's mission over that period. Each member is allocated a fixed amount of GIVE (100 by default) and can freely send any number of these tokens to other Circle members during the Epoch. Members can also opt-out if they receive funding elsewhere, allowing them to send GIVE but not receive it.
