Mining Difficulty
Bitcoin
Mining Difficulty measures how hard it is to find a valid block, adjusting to keep block times near 10 minutes.
Why it matters
It reflects the total competitive hash power securing the network.
How it is built
The protocol recalibrates difficulty every 2016 blocks based on recent block times.
What to watch
Rising difficulty signals growing security and miner competition; sharp drops signal miner capitulation.
