The observation window
This report covers 2026-10-07 21:34:13 UTC to 2026-10-08 19:00:00 UTC (end exclusive). Only observations inside this window contribute to the report. A partial-day window is not a full daily or monthly summary, and no earlier network history is inferred.

What the recorded values show
Individual hashrate estimates ranged from 38.23 PH/s to 52.62 PH/s. These are estimates from the node’s rolling window of up to 120 blocks. Neighboring readings share many of the same blocks; the range is not a direct measurement of mining equipment joining or leaving the network.
The first difficulty reading was 2.1846E19 and the last was 2.1846E19 (0.00% change between those readings). This is BLAKE2b difficulty. The raw export retains the numeric readings; the chart displays five-minute arithmetic means.
The 161 included headers were canonical when this snapshot was captured. The average block interval uses the elapsed timestamp between the lowest and highest included consecutive heights, divided by their height difference. Block timestamps come from miners and can be irregular. Future reorganizations may change the live canonical chain; this archive preserves the records used for this report.
