According to him, shortly before the block was mined, the participant’s rate surged to 259 PH/s. Kolivas noted that only one worker was connected to the pool. Typically, this account showed a significantly lower hash rate.
He also highlighted that this was the 300th block mined by a solo miner through CKpool.
As of June 5, the total computational power of the network stood at 796 EH/s. Under such conditions, the chance of success for an individual miner was 0.03%, or approximately 1 in 3,050.
Back in March, a solo miner mined block #887,212 and earned ~$250,000. This was achieved using a $299 device.
