Ever wondered how blockchains lock in truth? Proof‑of‑Work (PoW) powers Bitcoin with massive hashing power, but at a high energy cost. Proof‑of‑Stake (PoS) lets validators lock coins to secure the chain, cutting energy use while keeping security. New hybrids—PoS + PoW, Delegated‑PoS, Proof‑of‑History, and even Proof‑of‑Authority—blend speed, decentralization, and efficiency. Understanding these models is key to navigating crypto’s future.
