A » Proof of Work (PoW) is a consensus mechanism used in blockchain networks to validate transactions and create new blocks. It requires participants, known as miners, to solve complex mathematical puzzles. This process ensures network security by making it costly and time-consuming to alter any transaction history, thus preventing fraud and double-spending. Bitcoin is the most prominent example utilizing PoW, where miners are rewarded with cryptocurrency for their efforts.
