A book explaining how the monetary system has historically evolved into a layered structure
Here's a question that trips up even experienced Bitcoiners: if Bitcoin can only handle a handful of transactions per second, how can it ever be global money? Nik Bhatia's answer is that you're asking the wrong question. Money has always worked in layers. And once you see that, everything clicks.
Gold didn't process transactions either. It sat in vaults. Paper notes circulated above it as a second layer. Bank deposits sat above those as a third. The entire history of money is a story of layered systems, each layer trading off some trust for more speed and convenience, all anchored to something solid at the base.
Bhatia walks through this evolution with remarkable clarity - from the classical gold standard through Bretton Woods to today's fiat system, where central bank reserves replaced gold at the base and government bonds became the critical scaffolding. Central banks aren't just money printers in this framework. They're layer managers, maintaining the relationships between different tiers of money and credit.
Then comes the punchline. Bitcoin is the new base layer - incorruptible, globally accessible, and not controlled by any government. The Lightning Network is its second layer, handling fast, cheap transactions the same way banknotes once handled everyday commerce on top of gold. Building payment layers above sound money isn't a hack or a compromise. It's how money has always worked. Bitcoin is just doing it better.
Anyone who has ever said "Bitcoin is too slow to be money" needs to read this. It's also the single best book for understanding why the Lightning Network matters and where it fits in the bigger picture.
