The project team's FEC project (Domain Chain) based on blockchain technology will become a celebrity IP main platform. The FEC business is positioned to integrate value-added service resources into the supply chain, based on the supply chain's productization (using the main body name Mailbox, domain name, IP address, etc.) to assist users in the transformation of their economic value. On this basis, FEC will be applied to global consumption, finance, tourism, community and other fields of payment, relying on the technical characteristics of the blockchain to provide fast and convenient settlement payment and related services for merchants and consumers around the world.
