Cryptoeconomics

Eric Voskuil's axiomatic treatment of Bitcoin as money. Not a book about price or technology, but about the economic principles that have to hold for a money to survive contact with hostile states and rival currencies.

Cryptoeconomics works the problem from first principles. Each chapter takes an axiom or a property and pressure-tests it: censorship resistance, divisibility, fungibility, the structure of the mining market. Read it once and Bitcoin stops looking like a payments system and starts looking like a result.
