Ever wondered how blockchains stay secure? It all boils down to consensus mechanisms. Proof‑of‑Work (PoW) powers Bitcoin, burning energy to solve puzzles. Proof‑of‑Stake (PoS) lets validators lock crypto and vote on blocks, cutting power use. New hybrids and sharding aim to boost speed, reduce costs, and keep decentralization. Stay curious!
