Dofi is a trust society cornerstone operating system developed by the anonymous community of origin, which was spontaneously established by dooer community for one year. It is not a DAPP in the traditional sense, but a multi-dimensional technology aggregate of the fourth generation blockchain technology group with Tron blockchain as the bottom layer and can combine AI, big data and other technologies.
