Ever wondered how blockchains stay honest? The classic answer is proof‑of‑work (PoW) – miners race to solve math puzzles, securing the chain but burning energy. Proof‑of‑stake (PoS) flips the script: validators lock up coins and are chosen to forge blocks, slashing power use and speeding up confirmations. New hybrids—DPoS, PoA, BFT—mix speed, security and decentralization. Pick the right model for the right purpose.
