Proof-of-work (PoW)

What is Proof-of-Work (PoW)?

The proof-of-work consensus is the original mining consensus used in the Bitcoin network. Mining with a proof-of-work consensus means that a miner must have hardware equipment that is able to solve complex mathematical functions. So in this type of consensus, miners’ computing power will define their mining power.

Proof-of-work consensus requires massive amounts of energy to work. This is one of the main flaws of PoW..
