Bitcoin mining difficulty is a metric designed to reflect how difficult it is to mine a Bitcoin block, with a higher level of difficulty requiring more computing power to verify transactions and mine new coins.

With the continued growth in BTC mining difficulty comes a significant increase in the Bitcoin hashrate, the total combined computing power used to mine and process BTC transactions.
