GreenCoin - a BlackCoin's clone that has a specific modification on awards.GreenCoin is fully aware that the constant climate change is a severe problem. This is why it decides to give rewards to individuals that are part of this problem's solution. When a person does something that helps the environment, such as using a solar power system and replace part of the electricity usage, they can go to validate this power system quickly on the official GreenCoin website. It's free. Afterward, the site can be used for tracking carbon savings, which are rewarded with GreenCoins.GreenCoin is entirely free and voluntary. It is designed to empower people and help them understand that we have to care more. The goal is to form a caring community to grow and therefore improve the global environment. The idea is for people to share this platform with each other or use the open-source model to improve it even further.
