Public Blockchains

Public blockchains are open and decentralized blockchain networks where anyone can participate, transact, and validate transactions without permission. They are accessible to anyone with an internet connection and offer transparency, security, and censorship resistance. Public blockchains, like Bitcoin and Ethereum, rely on distributed consensus mechanisms and incentivize participation from a large number of nodes to maintain security and integrity. They provide a trustless environment where participants can interact and transact directly, without relying on intermediaries or central authorities.
