A front-end node is a user-facing application that allows individuals to interact with a blockchain network. These nodes typically handle the graphical interface and provide users with access to various functionalities, such as viewing account balances, sending transactions, and interacting with decentralized applications (dApps).Front-end nodes communicate with back-end nodes, often called full nodes or validators, which maintain the blockchain’s integrity by processing transactions and keeping a complete history of the ledger. While back-end nodes do the heavy lifting, front-end nodes focus on user experience and ease of use.Many wallets and dApp browsers serve as front-end nodes. They often include features like portfolio tracking, transaction history, and support for multiple cryptocurrencies. Security is crucial, as users interact with their assets through these interfaces. Thus, front-end nodes aim to provide a seamless and secure way for users to engage with blockchain networks without needing to understand the underlying technical complexities.
