A public node is a computer that participates in a blockchain network by maintaining a copy of the entire blockchain and validating transactions. Anyone can connect to a public node and access the information it holds, making these nodes integral for transparency and decentralization.Public nodes facilitate the network’s operation by verifying the legitimacy of transactions and blocks. They communicate with other nodes to ensure that all copies of the blockchain remain consistent and accurate. This helps prevent fraud and other malicious activities.Users can run their own public nodes if they have the necessary hardware and bandwidth. By doing so, they contribute to the network’s security and stability, while also gaining more control over their transactions and privacy. Public nodes are essential for users who want to engage with the network without relying on third-party services.
