Energy chain is an international blockchain team, committed to building a decentralized energy trading and management system integrating blockchain, Internet of things and Microgrid (such as decentralized energy trading between people; or automatic supply and marketing between things, such as new energy vehicles and charging piles). The team uses the characteristics of blockchain (based on qtum quantum chain) to build a distributed energy architecture and a new energy trading market, so as to improve the utilization rate of clean energy, enable residents to obtain more economical clean energy, and integrate the real-time physical flow, information flow and value flow between consumers and consumers in a decentralized manner. The energy chain will become an important link bridging the physical layer, information layer and value layer in the smart grid in the future, helping to achieve a truly decentralized and autonomous energy network.
