Cryptocurrency and the blockchain has somewhat of a murky reputation, clouded in hype and fear of dodgy dealings – but looking past the negatives, could Bitcoin's underlying technology actually be a new secret weapon for the charity and social impact sector? In this episode Adah Parris is joined by Raphaël Mazet to explore the potential of the blockchain for social good. He explains how his company, Alice.si, is harnessing the tech to build trust, transparency and impact into projects with partners such as St Mungos. Plus we meet Niall Dennehy, whose company AID:Tech is on a mission to bring digital identity to the underserved and underrepresented communities across the world.
