Bitcoin is the court. Lightning is the cash register.
In this episode of the Bitlemmas Podcast, Watson, B. Sovereign, and Drew review Mastering the Lightning Network by Andreas Antonopoulos. If you've ever asked whether Bitcoin can actually compete with Visa for everyday payments, this is the episode that answers it.
Lightning is not a new coin or a new chain. It's a contract system built on top of real Bitcoin, designed to handle fast, cheap, private payments without giving up self-custody. We break down exactly how it works, what can go wrong, and what you should do if you want to start using it safely.
