Difficulty

What is "Difficulty"?

Difficulty is the current estimate of the number of hashes required to find a new block on the Bitcoin network. In Bitcoin, difficulty is traditionally expressed as a relative value versus the genesis block, for which approximately 2³² hashes were required. In this metric, the value is presented in absolute terms - as the number of hashes.

Why is "Difficulty" important?

Difficulty reflects the amount of computational work required to find a block and therefore characterizes the level of competition among miners. Increasing difficulty typically accompanies a higher network hash rate, while decreasing difficulty can indicate reduced computational power. The metric enables analysis of mining dynamics and the cost level of block production.
