A private blockchain is a restricted, permissioned version of blockchain technology that is controlled by a single organization or a consortium. Unlike public blockchains, where anyone can participate, private blockchains require permission to access and contribute to the network. They offer enhanced privacy, security, and scalability, making them ideal for businesses that need to manage sensitive data or transactions within a closed ecosystem. Private blockchains are widely used in industries like finance, healthcare, and supply chain management, where confidentiality and control are critical. Features like faster transaction processing, customizable governance models, and better energy efficiency are some of the advantages of private blockchains. They enable businesses to benefit from blockchain technology while maintaining tighter control over data and access.
