It is designed to enable fast, low-cost, and scalable transactions by allowing users to open payment channels between each other, through which they can conduct multiple transactions without the need to record each one on the blockchain. The Lightning Network is seen as a potential solution to the scalability problems faced by many blockchain-based systems, and it is seen as a key enabler of the widespread adoption of cryptocurrencies. ## Notes - The Lightning Network is a "layer 2" payment protocol layered on top of Bitcoin. It is intended to enable fast transactions among participating nodes and has been proposed as a solution to the bitcoin scalability problem.
