Private Blockchain vs Public Blockchain

A private blockchain is a restricted, permissioned distributed ledger controlled by a specific organization or consortium where participation requires authorization. Unlike public blockchains, access to view and validate transactions is limited to approved participants only.

A public blockchain is an open, permissionless distributed ledger that anyone can join, view, and participate in without requiring approval from a central authority. Transactions are transparent and validated by a decentralized network of participants.
