Crypto Terms: POW

Proof of Work (PoW) is a consensus mechanism used in blockchain networks to validate and confirm transactions.

In a PoW system, miners compete to solve complex mathematical puzzles, with the first miner to find the solution being rewarded with newly minted cryptocurrency and transaction fees. This process requires significant computational power, making it costly and time-consuming.

However, it ensures network security and prevents double-spending. Bitcoin, the first cryptocurrency, uses PoW as its consensus mechanism.
