Difficulty Epoch

Data updated All times UTC

The current difficulty epoch day by day, what each retarget does to the hashprice, and the last closed epoch, from BMM's own Bitcoin node.

Difficulty → hashprice

Each retarget changes PPS by 1 ÷ (1 + Δ) − 1 at a stroke, so the size of the next difficulty adjustment translates directly into the hashprice outlook.

Current epoch

The difficulty epoch in progress, filled through the day from BMM's own Bitcoin node. Kept here until it closes; then it moves to the prior epoch review below.

Current epoch

Every figure from BMM's own Bitcoin node, updated through the day. Daily ranges count full UTC days only: the first day of an epoch and today are partial.

Blocks per UTC day in the current epoch

Red: 144 blocks or more in the day (faster than 10 minutes: difficulty heads up, PPS down). Blue: fewer than 144 (difficulty heads down, PPS up). Pale: partial days. Empty slots: days still to come at the 10-minute target.

Prior epoch review

The last closed difficulty epoch, kept here until the next one closes, and the epochs before it.

Blocks per UTC day in the prior epoch

Past epochs

Days and blocks per day from the difficulty ratio at each retarget (consensus rule: 2,015 block intervals against 1,209,600 seconds). Implied hashrate = difficulty × 2^32 × blocks per day ÷ 86,400. PPS = 3.125 BTC × 86,400 × 10^15 ÷ (difficulty × 2^32). Fees as % of the block subsidy; ≈ = BMM estimate from daily node data.Source: BMM node
