The opposite of a public blockchain is a private blockchain, such as Hyperledger Fabric. In a private blockchain, also called a permissioned blockchain, the entity that owns and controls the blockchain grants and revokes access to the blockchain data. Because most enterprises manage sensitive or private data, private blockchains are commonly used because they can limit access to that data.

The blockchain data is still transparent and readily available but is subject to the owning entity’s access requirements. Some have argued that private blockchains violate data transparency, the original intent of blockchain technology. Although private blockchains can limit data access (and go against the philosophy of the original blockchain in Bitcoin), limited transparency also allows enterprises to consider blockchain technology for new apps in a private environment. Without the private blockchain option, the technology likely would never be considered for most enterprise applications.
