Private blockchains are more similar to traditional shared databases than public blockchains. Private blockchains, like public blockchains, store records as pre-assembled ledgers on peer-to-peer nodes. Private blockchains, which are more centralised and often rely on third parties to carry out tasks, are more centralized, with organizations or individuals monitoring the network. Private blockchains are not available to the general public, and nodes are frequently non-anonymous entities known to one another, such as manufacturers and suppliers. Powers are delegated to organizations or individuals by an operator or a protocol.
