Nathaniel Popper opens by tracing Bitcoin's origins to a specific intersection of cryptographic technical innovation and libertarian ideological motivation, embodied in the mysterious pseudonymous figure Satoshi Nakamoto.

Why this dual origin matters for understanding Bitcoin's development:

• Bitcoin's underlying technology solved a genuine technical problem (achieving decentralized digital trust without a central authority) that had stumped cryptographers for years
• Simultaneously, its early adopters were substantially motivated by libertarian and anti-establishment ideological commitments, not purely technical interest
• This combination of genuine technical innovation and strong ideological motivation shaped Bitcoin's subsequent, often turbulent development trajectory

This opening establishes the book's dual technical-and-ideological narrative lens, necessary for understanding Bitcoin's unusual early community and subsequent development.
