GREEN

GreenAir is a decentralized ecosystem that solves two problems: the current energy expenditure in the process of mining cryptocurrencies and derivatives and the adverse effects of climate change. All this through its different devices powered by solar energy. It will also feature other areas such as a pollutant swap, tokenized carbon credits and more applications along the roadmap.
