Think of consensus as the blockchain’s decision engine. Proof‑of‑Work burns electricity to reach agreement, making it secure but costly. Proof‑of‑Stake uses validators’ holdings as a stake, slashing misbehavior and cutting power use. Next‑gen models—Authority, Delegated PoS, hybrids—aim to balance speed, security, and sustainability. Understanding these basics lets you spot the next big shift.
