Yes I know... 'hashrate' is just an estimate of the current rate.
But according to
https://mempool.space/graphs/mining/hashrate-difficulty#1y
The network today just took a massive leap up in hash to a total 897 EH.
The previous high was 811 on October 30th (according to mempool.space)
897 - 811 = 86
86 / 811 x 100 % = 10.6%
So an increase of over 10% above its previous high of about 3 weeks ago.
That's a 10% increase in just a few weeks. Did a large-scale mining facility just come online?
It 'looks' significant on the 1 year chart... and even on the 2 and 3 year charts it looks obscene...
