LC Coin is a coin that is the first to achieve environmental protection and carbon neutrality, and uses blockchain technology to record waste history and support the development of environmentally friendly products. A sustainable ecosystem centered on the environment and people. To create it, transform the existing fossil energy-oriented paradigm into new and renewable energy, trying to establish a virtuous circle environment that solves climate change and environmental problems. In response to human destruction of nature and the resulting climate change crisis, we provide solutions for human life co-existing with the post-COVID-19 environment, look at environmental pollution issues from multiple perspectives, and develop projects that address them.
