Layered Money — Nik Bhatia

Overview

Layered Money by Nik Bhatia offers a clean mental model for understanding money: think of it as a system of layers. Gold sat at the base, with paper notes and bank deposits as higher layers that promised redemption for the metal below; modern money stacks central-bank reserves, commercial-bank money and other claims in a similar hierarchy. Bhatia applies this framework across monetary history and then to the future, positioning Bitcoin as a new base layer with the Lightning Network as a faster second layer.

The strength is clarity and concision. At roughly 200 pages, it's short and readable, and the "layers" lens is a genuinely useful way to organise how banks, central banks and settlement actually relate. The honest caveats follow from that brevity: it's more of a lucid primer than a deep analysis, so readers wanting rigorous argument or heavy sourcing may find it thin, and its treatment of Bitcoin and Lightning is more framework-fitting than exhaustive.

Buy it if you want a concise, clarifying framework for how monetary systems are structured and where Bitcoin and Lightning fit in. If you want depth and rigour, treat it as a fast on-ramp and follow it with something more substantial like Broken Money.
