Private Permissioned Blockchain

Definition ∞ A private permissioned blockchain is a distributed ledger technology where participation is restricted and controlled by a central authority or consortium. Only authorized nodes can join the network, validate transactions, or access certain data. This contrasts with public, permissionless blockchains.
Context ∞ Private permissioned blockchains are frequently adopted by enterprises and consortia for specific business applications requiring enhanced privacy, control, and efficiency. They offer advantages in regulated industries by allowing for controlled access and faster transaction finality, though they operate with a different trust model compared to public chains.
