Fundamental obstacles to the full globalization of the digital economy are being identified. The reasons of their occurrence are analyzed both at the level of deep properties of information environments in which run economic processes, and at the level of logical bases of computer-networking architectures of the Global Computer Environment (GCE), used now for digitalization of the economy. The ways of elimination of the revealed reasons on the base of the general model of universally programmable and cyber-secure distributed computing are shown. In the growth of this theme the architectural principles of the new class of mass universal network computers with non-microprocessor architecture are offered, which open possibilities of formation in aggregate resources of the current GCE of the universal algorithmic space of the digital economy.
