What is PoW?

Proof of Work (PoW) is a consensus mechanism used in many blockchain networks to verify transactions and maintain the integrity of the blockchain. In PoW, miners compete to solve a complex math problem to add the next block to the blockchain. The first miner to solve the problem receives a reward in the form of cryptocurrency. The miners must use powerful computers to solve the math problems and secure the network. PoW requires a significant amount of computing power and energy. Bitcoin is the best known example of a cryptocurrency that uses PoW.
