On Wednesday a solo Bitcoin miner successfully mined block 975427 on the Bitcoin blockchain. The block was found through CKPool Solo, which reported the discovery as the pool’s 321st block since it began operating.
Solo mining activity in 2026
This is the 38th block mined by an independent operator in 2026. The miner used a hash rate of about 161 terahash per second (TH/s). CKPool Solo’s maintainer noted that a miner with this capacity has roughly a one‑in‑126 chance of finding a block over a year.
Comparison of odds
Large mining pools such as Foundry and Antpool dominate block production, yet solo miners still obtain a chance in each 10‑minute interval. The 1‑in‑126 annual probability for a 161 TH/s miner is far higher than the odds of winning major lotteries, which are measured in hundreds of millions to one.
Financial impact
At the time of the find, the block reward of 3.125 BTC plus transaction fees was valued at approximately $230,000, based on Bitcoin trading just above $73,500.
Industry context
The recent solo discoveries highlight ongoing interest in independent mining despite the dominance of large pools. New mining pools and compact ASIC devices continue to emerge, keeping solo mining a viable option for some participants.
