B Block Odds Lab

Live difficulty tracker

Bitcoin difficulty changed? Your solo-mining odds changed too.

Bitcoin difficulty adjusts every 2,016 blocks. When it moves, Bitaxe, NerdMiner, USB stick miner, and solo pool odds all need fresh math. This page watches the next retarget and routes you back into the calculator when the odds change.

Why this can bring in new readers

Difficulty adjustment searches happen on a schedule. People look up the next retarget, see a percent move, then wonder what it means for their miner. Block Odds Lab should be waiting there with the practical answer: rerun the odds with current difficulty before buying, tuning, or posting old screenshots.
