GSMA Blockchain for Wholesale Roaming MVP Report
On the direction of the GSMA board, the Blockchain for Wholesale Roaming (BWR) initiative was created to develop a reference industry implementation and common standardised building blocks for future industry blockchain implementations. The remit of BWR is to understand operator business requirements and evaluate how blockchain technology can meet these and to assess the benefits of using blockchain technology in the context of end-to-end wholesale roaming clearing and settlement business. The first Minimal Viable Product (MVP) focused on creating common modular architectural components and developing an application for discounting settlement process. This document sets out the outcome of the first MVP and the benefits of using blockchain technology. The purpose is to inform future MVPs and commercial wholesale roaming solutions.
