The purpose of the Ontology framework is that it is not intended to operate as a single blockchain. Instead, the technology will allow businesses to make full use of both a private and public blockchain. Let me explain this in more detail. A financial institution will not want to put all of their data on a public blockchain as it will allow their competitors to access all of their information. In this sense, they will install the Ontology blockchain, which is a private blockchain only accessible by the financial institution, or anyone else that they choose to share permission with.
