Proof of Work (PoW) requires miners to solve complex cryptographic puzzles to validate transactions and add new blocks. It’s secure but energy-intensive (used by Bitcoin). Proof of Stake (PoS) selects validators based on the number of tokens they stake and their reputation. It’s faster, more energy-efficient, and less costly to operate (used by Ethereum 2.0). |

Key point: PoW secures the network with computation, PoS secures it with economic stake.
