The Genesis Book

Bitcoin did not appear out of nowhere. For decades before Satoshi, a scattered community of cryptographers, cypherpunks and free-market economists was chasing the same dream: money you can hold and send without trusting a bank, a company or a government. Aaron van Wirdum traces that lineage in careful detail — David Chaum's DigiCash, Adam Back's Hashcash, Wei Dai's b-money, Nick Szabo's bit gold, Hal Finney's reusable proof-of-work — alongside the Austrian economics of Hayek and Mises that told these builders why a fixed, apolitical money was worth fighting for. Each attempt solved a piece of the puzzle and stumbled on the same wall. By the final chapters you can see exactly which ideas Satoshi inherited and the one problem he finally cracked.

Most people meet Bitcoin as a finished product and never learn why it is built the way it is. This book gives you the backstory, so the design choices — a fixed 21-million supply, proof-of-work, no central issuer — stop feeling arbitrary and start feeling inevitable. Read it once you have the basics down and want the deeper 'how did we get here' that makes the whole system click.
