Are lightning invoices based on bitcoin addresses?
Could you elaborate on whether lightning invoices are inherently tied to Bitcoin addresses? I've heard that the Lightning Network, as a second-layer solution to Bitcoin's scalability issues, introduces a new payment system. Does this mean that lightning invoices operate independently from traditional Bitcoin addresses, or are they still rooted in the core Bitcoin infrastructure? I'm curious to understand how these invoices work and if they rely on the same addressing system as the Bitcoin blockchain.
