What is a Permissioned Blockchain?

A permissioned blockchain is a type of blockchain network where access and participation are controlled by a central authority or consortium of trusted entities. Unlike public blockchains, which are open and permissionless, permissioned blockchains require users to be authenticated and authorized before they can interact with the network. Permissioned blockchains are often used in enterprise and government applications where privacy, security, and regulatory compliance are essential.
