Bitcoin Difficulty Retarget Estimation

Bitcoin Difficulty Retarget Explained

This chart shows the estimated next difficulty adjustment based on the current mining pace. The difficulty adjusts every 2016 blocks (approximately every 2 weeks) to maintain a 10-minute average block time.

The current pace is calculated by comparing the actual time taken to mine recent blocks against the expected 10-minute interval. A pace of 100% means blocks are being mined exactly on schedule, while values above 100% indicate faster mining and values below 100% indicate slower mining.

The adjustment ratio is capped between 0.25x and 4x to prevent extreme difficulty changes. The actual timespan is measured over the last 2016 blocks, and the expected timespan is 20160 minutes (14 days).
