A public blockchain is a decentralized and open network where anyone can participate in the consensus process and access the transaction data. These blockchains are completely transparent, secure, and immutable, with no central authority controlling the network. Public blockchains, such as Bitcoin and Ethereum, enable peer-to-peer transactions and support the development of decentralized applications (dApps). They are ideal for cryptocurrencies, decentralized finance (DeFi), and applications where transparency, security, and trustless interactions are paramount. Public blockchains allow anyone to contribute to the network’s growth and validation.
