Private Blockchain

Definition ∞ A private blockchain is a distributed ledger network where access and transaction validation are restricted to authorized participants. Unlike public blockchains, it operates under the control of a single entity or a consortium, determining who can join and participate. This setup offers enhanced privacy, faster transaction speeds, and greater control over governance, making it suitable for enterprise applications. While still utilizing cryptographic security, its centralized control differs significantly from open, permissionless networks.
Context ∞ The discussion surrounding private blockchains often centers on their applicability for specific business needs requiring confidentiality and controlled access, contrasting with public blockchain ideals. A key debate involves the degree of decentralization and transparency these networks truly offer, given their permissioned nature. Future developments will likely see increased interoperability between private and public blockchains, facilitating data exchange while preserving privacy where needed.
