Ever wondered why Bitcoin burns energy while Ethereum moves to proof‑of‑stake? Proof‑of‑Work forces miners to solve math puzzles, locking in security but wasting power. Proof‑of‑Stake lets validators lock coins to vote on blocks, cutting energy use and slashing inflation. New ideas—proof‑of‑authority, proof‑of‑history—blend speed, decentralization, and eco‑factors. Understanding these layers helps you pick projects that fit your values and yield.
