The OpenLitterMap Foundation has created a blockchain reward system for anyone who wants to help map plastic pollution. Littercoin is a Citizen Science Open Data Litter-Mapping Game that allows users anywhere to receive recognition for mapping and producing open data on plastic pollution. Users can choose to receive a weekly payment in Littercoin, which is mined through the production of open data. The data produced is then verified, before being made accessible for anyone to download and reuse for any purpose.
