Bitcoin: A Peer-to-Peer Electronic Cash System

What they found
The nine-page paper that started crypto. Nakamoto proposed a system for electronic payments that does not rely on a trusted third party: transactions are broadcast to a network, grouped into blocks, and chained together using proof-of-work, so that rewriting history would require redoing more computation than the honest network can produce. The paper describes the incentive structure (block rewards and fees) that pays miners to secure the network and analyzes the probability that an attacker could reverse a payment.
What you can use
- Understanding what Bitcoin actually is (a settlement system secured by computation) is a prerequisite for evaluating any claim about its value.
- The security model depends on honest miners controlling the majority of hash power; that is an economic assumption, not a mathematical guarantee.
- Nothing in the paper concerns price, scarcity narratives, or investment; those are later additions.
Caveats
A design document, not empirical research. Later protocol changes and the actual behavior of the network differ from the paper in places.
