07 Oct 2019 --- The UN Development Programme (UNDP) is launching a chocolate bar as part of a social experiment. The Other Bar uses blockchain technology to give consumers the choice to donate directly back to cocoa farmers or to get a discount on their next purchase. The FairChain Foundation – who conceived the idea and developed the technology behind the bar – highlights that global brands spend over £500 billion (US$615 billion) a year on marketing, while only £140 billion (US$171.8 billion) is needed to end global poverty.
