The Lightning Network is a second-layer protocol built on top of Bitcoin that enables fast and low-cost transactions by creating off-chain payment channels between users. It allows multiple transactions to occur instantly and securely without needing to record every transaction on the Bitcoin blockchain, reducing congestion and fees. By settling only the final balance on-chain, the Lightning Network enhances Bitcoin’s scalability and usability for everyday microtransactions.
The Lightning Network offers blockchain users significantly faster transaction speeds and drastically lower fees compared to on-chain Bitcoin transfers. It enhances privacy by keeping most transactions off the public blockchain while maintaining Bitcoin’s security. Additionally, it enables microtransactions and greater scalability, making Bitcoin more practical for everyday use.
