Proof of Work (PoW) - Bitcoin's Security Model
Proof of Work (PoW) is the original consensus mechanism that powers Bitcoin. Miners compete to solve complex mathematical puzzles, and the winner gets to add the next block to the blockchain and earn rewards. Learn why PoW is considered highly secure, why it uses significant energy, and how Bitcoin mining actually works.
