Private blockchains are distributed ledger networks where access and participation are restricted to a select group of authorized entities. Unlike public blockchains, which are open to anyone, private versions require permission to read, write, or validate transactions. They typically offer higher transaction speeds and more granular control over data visibility. These systems are often deployed by consortia or individual enterprises.
