The Lightning network has been designed to facilitate payments and attract more users. This system can completely change the game for Bitcoin. At the moment, most users consider Bitcoin as a store of value, but not as a means of payment, because of possible high fees and processing times in high-usage times. With the Lightning Network, Bitcoin will be able to become cheaper and more efficient, which will be a clear competitive advantage over some altcoins. Lightning Network is a set of rules that rely on the Bitcoin blockchain and are specifically designed to facilitate micropayments. All transactions will be based on smart contracts and the system itself will control the processes. So, if Bitcoin is layer 1, the Lightning network is considered a Layer 2 solution. This is made possible by creating payment channels between two users. Payments can also be made between users indirectly connected via network channels.
