Abstract

The Pay-with-a-Group-Selfie (PGS) project, funded by the Melinda & Bill Gates Foundation, has developed a micro-payment system that supports everyday small transactions by extending the reach of, rather than substituting, existing payment frameworks. PGS is designed to work with devices with limited computational power and when connectivity is patchy or not always available. Once the concept of PGS has been accepted as demonstrated by the experimentation, we move to integrating elements and tools intended to ease federation or incorporation of the large spectrum of stakeholders. Embedding a digital wallet is one step in that vision. We analysed the system architecture that will be needed and the requirements drive us to opting for blockchain based architecture. We are then presenting the applicability of a blockchain as platform.
