Proof-of-Work — consensus mechanism where validators (miners) expend computational work to add blocks. Bitcoin uses PoW; Ethereum used PoW until September 2022. PoW provides high security but consumes substantial energy. Critics focus on the energy use; defenders argue it is the price of decentralized, settlement-grade security.
