What is Public Blockchain

Public blockchains are permissionless databases that are frequently utilised for cryptocurrency. Because anybody may put up a node on this form of blockchain, networks are frequently large. The data is available for the whole public to access. Nodes and users stay anonymous to safeguard people's identities. On public blockchains, consensus procedures are required to verify that all data added to a network is unified and legitimate. Many nodes serve as miners and validators, and many keep append-only copies of data. Public blockchains include Ethereum and Bitcoin.
