Ever wondered how blockchains stay secure? Proof‑of‑Work (PoW) pushes miners to solve puzzles, while Proof‑of‑Stake (PoS) lets validators lock coins to vote on blocks. New hybrids—Proof‑of‑Authority, Delegated‑PoS, and even eco‑friendly consensus—blend speed, decentralization, and energy efficiency. Understanding these layers unlocks the trade‑off between security, speed, and sustainability.
