What’s the future? Addressing the Global Plastic Pollution Problem through Blockchain Technology

You may have first heard about blockchain technology over this past year as the price of different cryptocurrencies swung wildly and made news. OpenLitterMap aims to tackle the global plastic pollution problem through their reward system utilizing blockchain technology called Littercoin. Littercoin rewards people for contributing open data about litter they come across in their cities, reporting information such as litter location, type, and even brand information. Global plastic pollution is a massive problem that requires large scale solutions to solve. And through its efforts to tackle plastic pollution OpenLitterMap aims to to prevent plastics from entering landfills and the oceans.
