What is Private Blockchain?

A private blockchain system is a distributed network that operates with key differences to an open public blockchain protocol like Ethereum or Bitcoin. Private blockchains are often governed by a single entity and used by large organizations — enterprises and government, for example — that require access management, censorship rights, and privileged privacy models. While private blockchains are built with speed and scalability in mind to serve the needs of the client organization, they are not decentralized or secured by a distributed network.
