BTC: Daily Estimated Proof-of-Work Hashes

Bitcoin Daily Estimated Proof-of-Work Hashes was 85,387,605,611,198,993,277,753,753.6 estimated hashes on 7 Nov 2026 (latest daily value).

Estimated double-SHA256 hashes behind each UTC day's blocks, derived from their difficulty.

Why use it. Express each day's mining work as a hash count implied by block difficulty. How to read it. Higher values mean more estimated work went into the day's blocks. This is a conventional difficulty-based estimate, not measured physical hashes, exact target-based expected attempts or Bitcoin Core chainwork, and no hash-rate-times-block-count formula is used. A negative parent value is undefined. Only complete UTC days are defined; missing inputs are gaps, and provisional labels remain.

Calculation. Multiply the accepted daily hash rate estimate in EH/s by 86,400 seconds and 10^18 hashes per exahash. That parent divides the sum of retained floating-point relative block difficulty times 2^32 by 86,400 and 10^18, so the result restates that difficulty sum; its 40-significant-digit rounding is kept and lost source precision is not recovered.
