Abstract: We present Carbon, an asynchronous payment system. To the best of our knowledge, Carbon is the first asynchronous payment system designed specifically for a client-server architecture. Namely, besides being able to make payments, clients of Carbon are capable of changing the set of running servers using a novel voting mechanism -- asynchronous, balance-based voting.
