Want to know what keeps blockchains running? Proof‑of‑Work (PoW) forces miners to solve math puzzles, burning huge energy to secure the network. Proof‑of‑Stake (PoS) swaps that for coin‑holding power, letting validators lock up assets to propose blocks, cutting energy costs. Then hybrids like DPoS, PoC and sharding blend speed, security and decentralization. Understanding these tools helps you spot the next big shift in crypto.
