This document discusses Circles, a proposed universal basic income system implemented on the Ethereum blockchain. It would provide each person with a basic income by generating a small amount of currency each week for every account. Accounts can trust each other to share in reserve funds. Groups can also be formed where members convert their private currencies to group currencies. The value of the currency depends on economic factors like growth rate and how widely it is used in networks and groups. Circles aims to provide basic income without debt obligations and in a decentralized peer-to-peer manner on the blockchain.
