On Money

Explores the four functions of money, from barter to commodity, fiat, and cryptocurrency, building a complete taxonomy of currency from first principles.

Explores the international monetary system: exchange rates, currency regimes, the dollar's dominance, pegs and crises, and how money became a geopolitical weapon.

Explores central banking, monetary policy, and the payment rails that settle every dollar, examining the central bank's balance sheet, policy tools, transmission mechanisms, and the dual mandate of stable prices and maximum employment.

Explores debt, bonds, the yield curve, and the cost of borrowing, building from time value and present value through bond mechanics, yield curves, credit cycles, and sovereign debt.

Explores the cryptographic machinery of trustless systems—hashing, consensus, smart contracts, DeFi, and blockchain scaling—showing how mathematics and incentives replace institutional trust.

Explores the design space of money through four independent dimensions—issuer, backing, ledger, and privacy—and maps how these choices recombine to shape the future of currency and control.
