What is a bitcoin L2 network?
Can you please explain what a Bitcoin L2 network is? I've heard it mentioned in discussions about scalability and improving transaction speeds on the Bitcoin blockchain, but I'm not entirely clear on its specifics. How does it work? Are there any benefits or drawbacks to using a Bitcoin L2 network? And what are some examples of popular Bitcoin L2 networks that are currently in use? I'm interested in learning more about this topic and how it could potentially impact the future of Bitcoin and other cryptocurrencies.
