Fundamentals¶
Core monetary concepts — what money is, why it exists, and what makes it work. From the problem of barter and the double coincidence of wants to the five properties of good money.
Forms of Money¶
The currencies that have served as money throughout history — from cattle and cowrie shells to the Lydian stater, gold, the dollar, and Bitcoin.
Debasement¶
The recurring pattern of monetary destruction. How governments have debased money through coin clipping, inflation, and hyperinflation — and the economic law that explains why: Gresham's Law.
Institutions¶
The organizations and systems that control money — from the Federal Reserve and Bretton Woods to Japan's Kabunakama merchant guilds.
People¶
The figures who shaped monetary history — from Copernicus and Gresham to David Chaum, Nick Szabo, Hal Finney, and Satoshi Nakamoto.
Precursors¶
The cryptographic and technological innovations that made digital money possible — cryptography, public key cryptography, hash functions, proof of work, and early digital currencies like DigiCash, E-Gold, B-Money, and Bit Gold.
Digital Money¶
Money in the digital age — Bitcoin, blockchain, mining, Metcalfe's Law, and the network effect.
Satoshi's Writings¶
The words of Bitcoin's creator — from the whitepaper that started it all to Satoshi's views on sound money, trust, mining, Bitcoin's design, and key correspondence.
Research¶
Peer-reviewed and original research on Bitcoin — including Metcalfe's Law valuation, viral adoption, price manipulation, and more.
