Kaini Industries has developed the digital social currency HullCoin. HullCoin is generated by positive social action taking place within communities aligned with the work undertaken by community based organisations. People undertaking activities that benefit themselves or the lives of others can be issued with HullCoin as recognition for this action. HullCoin then accepted as a form of discount with participating retailers. HullCoin is also using pioneering blockchain technology that underpins bitcoin to facilitate this ecosystem.
