Abstract

The goal of this paper is to propose an open platform for secure and interoperable virtual community currencies. We follow the established information systems design-science approach to develop a prototype that aims to combine best practices for building mutual-credit community currencies with the unique features of blockchain technology. The result is a specification of an open Internet platform that enables users to join and to host customized community currencies. The hosted currencies can be classified as credit-based future type of money with decentralized issuance. Furthermore, we describe how the transparency, security and interoperability properties of blockchain technology offer a solution to the inherent problems of existing, centrally operated community currency software. The characteristics of the prototype and its ability to fulfil the design-objectives are examined by a relative evaluation against existing payment and currency systems like Bitcoin, LETS and M-Pesa.
