BTC: Observed Hash Rate — 90-Day Mean

Bitcoin Observed Hash Rate — 90-Day Mean was 969.1 EH/s on 7 Nov 2026 (latest daily value).

Mean of the latest 90 UTC daily difficulty-derived observed hash-rate estimates, including the plotted day.

Why use it. Compare the estimated network work rate over a stated daily window while reducing short-term block-arrival noise. How to read it. This is a statistical estimate, not measured miner hardware capacity. Each day has equal weight. At least 90 daily observations are needed; missing inputs leave a gap, and partial daily input makes the result partial. A proved empty day contributes zero estimated work rather than a carried hash-rate value.

Calculation. For each UTC day, sum canonical block difficulty × 2^32, divide by the full 86,400 seconds, and divide by 10^18 for EH/s. Apply sma(a,90) to those daily observations with 40-digit Decimal rounding. An open day's denominator remains the full day and its label remains partial. Use published source coverage, history and finality rather than the window name as completion evidence.
