Ontology represents a new class of blockchain based, decentralized networks that aim to solve problems currently plaguing established platforms and providing significant enhancements from recent technological developments. In particular, the implementation of fully homomorphic encryption, a recent development in cryptography, enables the data exchange of the Ontology platform to provide limited access control for private data as specified by a company or organization. This is a substantial improvement over existing models and gives the data exchange an added layer of useful functionality.
