What is layer 2 bitcoin scaling?
Could you please elaborate on the concept of layer 2 bitcoin scaling? I've heard about the need to scale Bitcoin's capabilities to handle increased transaction volumes, but I'm not entirely clear on the specifics of layer 2 solutions. Could you explain in a concise manner how layer 2 scaling works? What are some of the key benefits it offers? And how does it differ from layer 1 scaling solutions? Thank you for clarifying this important topic in the cryptocurrency space.
