A consensus mechanism used in some blockchain networks, including Bitcoin, that requires participants, known as “miners”, to use computing power to solve complex mathematical puzzles. The process validates transactions and adds new blocks to the chain. The first miner to solve each puzzle earns newly issued cryptocurrency, called a “block reward.” See Proof of Stake
