Proof Of Work(POW)

Proof of work is the mechanism used in cryptocurrency mining for validating transactions and mining new tokens.

It requires network members to expend effort solving a mathematical puzzle to prevent anybody from gaming the system.

To process these puzzles requires huge amounts of energy, which only increases as more miners join the network.

POW is used in Bitcoin and other cryptocurrencies to process peer-to-peer transactions securely without a third party.

To hack a blockchain network in proof of work; one needs to gain access to more than 50% of computing power, making it almost impossible to hack.
