The Lightning Network is a second-layer solution designed to enable faster and cheaper transactions on a blockchain. It allows users to create payment channels between them, which can be used to conduct multiple transactions off the main blockchain.These payment channels work by locking a certain amount of cryptocurrency in a multi-signature wallet. Once the channel is established, users can make transactions between themselves without needing to record each one on the blockchain. This significantly reduces the time and fees associated with transactions.When the users are done transacting, they can close the channel, and the final balance will be recorded on the blockchain. This method enhances scalability, as it alleviates congestion on the main network by handling many smaller transactions off-chain.The Lightning Network aims to improve user experience by allowing instant payments, making microtransactions feasible, and lowering fees. It is particularly useful for everyday transactions where speed and cost efficiency are essential.
