As a result of yet another recalculation of Bitcoin mining difficulty, the metric rose by 3.6%, to 17.55 trillion hashes.
The previous all-time high for difficulty was observed in mid-July.
The rise in difficulty occurred amid a decline in the network hash rate. A week ago this metric rose to a new all-time high, but by Sunday, August 23, it had fallen to a monthly low of 119.4 EH/s.
Earlier reports indicated that the decline in hash rate of leading Bitcoin mining pools was driven by floods caused by heavy rains in China’s Sichuan province.
