The Lightning Network is a "Layer 2" payment protocol that operates on top of a blockchain-based cryptocurrency (like Bitcoin). It enables fast and instant transactions between participating nodes and has been touted as a solution to the Bitcoin scalability problem. It features a peer-to-peer system for making micropayments of cryptocurrency through a network of bidirectional payment channels without delegating custody of funds.
Now you could use it for real payments and stay in control of your funds with the ability to pay
anywhere instantly, but to do so you need to have a lightning wallet setup.
