More technology that requires miners to solve computationally difficult math problems in order to add new blocks onto the blockchain. These functions produce data that is used to validate that a substantial amount of work has been carried out, thus the name “proof of work.” Solving these equations will typically result in the winning A miner is an individual or organization that "mines" crypto...

Proving these functions are often time-consuming and computationally expensive, sometimes this cost of mining can even outweigh the price of the reward, though this is not common.
