The Proof-of-Work section details Bitcoin's revolutionary consensus mechanism that secures the network without a central authority.

This page explains: • How proof-of-work uses computational puzzles (SHA-256 hashing) • The role of the "nonce" in mining • Why proof-of-work makes the blockchain immutable • How it solves the majority decision problem • The "one-CPU-one-vote" principle

This is one of the most important sections of the whitepaper, introducing the mining concept that secures Bitcoin to this day.

Key Concepts Covered: • Proof-of-Work Mechanism • Mining & Nonce • Longest Chain Rule • One-CPU-One-Vote • Exponential Difficulty
