A
permissioned blockchain is a type of blockchain where access and participation are controlled by a centralized authority. It requires permission or approval to join the network, make changes, or validate transactions. Only authorized entities or individuals can be part of this blockchain, ensuring higher security and privacy control compared to public blockchains like Bitcoin.
