Bitcoin's threat model mapped end-to-end: what the protocol trusts, what it defends against, how each attack is countered, and where open risks remain.
How Bitcoin nodes agree on a single chain: SHA-256d proof of work, the difficulty adjustment algorithm, block validation rules, fork resolution, and probabilistic finality.
