Difference Between Public Blockchain and Private Blockchain

Public blockchains are open to anyone to join and participate in the network, while private blockchains are restricted to a certain group of participants. Public blockchains are decentralized, transparent, and secure, with no central authority controlling the network. On the other hand, private blockchains are centralized and controlled by a single entity or organization.

In a public blockchain, transactions are verified and recorded by a network of nodes, whereas in a private blockchain, transaction validation is controlled by pre-selected nodes or validators. Public blockchains are typically used for cryptocurrencies and other public applications, while private blockchains are often used for enterprise applications where data privacy and control are essential.

Overall, the key difference between public and private blockchains lies in their accessibility, governance, and level of decentralization. Public blockchains offer greater transparency and immutability, while private blockchains provide more control and privacy to the participants.
