Dfinity seeks to create an intelligent, decentralized cloud, an enormous blockchain that will support corporate IT systems. Dfiniti is expected to be less expensive than centralized services. This will be achieved through cheaper system maintenance and R&D spending. Dfinity expects up to 80% savings. As for technological solutions, the whole Dfinity system and all processes, including economic ones, are managed by the Blockchain Nervous System (BNS). No public ICO is planned, but a huge community airdrop of 1.25% of the tokens instead, coupled with a pre-sale round (which is active right now).
