Consensus keeps blockchains honest. Proof‑of‑Work (PoW) burns massive energy to solve puzzles, giving security at the cost of power. Proof‑of‑Stake (PoS) lets holders lock coins to validate blocks, cutting energy use and speeding up transactions. New hybrids—DPoS, PoA, or Proof‑of‑Space—merge speed, scalability, and decentralization, shaping the next era of crypto.
