The Lightning Network is a second-layer solution designed to improve the scalability of the Bitcoin blockchain. It allows users to create off-chain payment channels, enabling faster and cheaper transactions without congesting the main blockchain. This technology helps facilitate microtransactions and enhances the overall efficiency of the network. By using the Lightning Network, users can conduct multiple transactions without needing to record each one on the Bitcoin blockchain immediately. Instead, only the final balance is settled on-chain, reducing fees and transaction times. This innovation aims to make Bitcoin more practical for everyday use and broader adoption.
