When you cut a tree and sell the wood, you will earn money. When you plant a tree, you are creating value, but you won’t get paid. Ecological value is not well articulated in our economy. The ECO coin aims to fix this. It is a new cryptocurrency that positively rewards people with ECOs for their sustainable actions. It is also the first cryptocurrency to be backed by sustainable assets; every ECO coin is backed by one tree. As more ecological assets are added to the system, more ECO coins become available. This also makes the ECO coin a living currency. Just as our ecology cycles through growth and decay, so too do ECO coins. ECOs coins are born, live and decay over time. The currency is governed by a Decentralised Autonomous Charity (DAC) so that not one organisation, but all those who use it have a voice in its development. Sustainable actions are verified by the crowd, through smart IOT integration and by certified vendors.
