A solo miner operating simply 6 terahashes per second of computing energy has overcome odds of about 1 in 180 million to mine a full Bitcoin block by way of the CKpool pool. In accordance with CoinDesk, the miner secured 3.146 BTC plus transaction charges — a payout value round US$270,000 at present charges, regardless of commanding solely about 0.0000007% of the community’s estimated 855.7 exahashes/sec of hash‑price.
The determine was confirmed by CKpool creator Con Kolivas, who mentioned that the miner solely had “a one in 180 million likelihood” of fixing a block on any given day. The miner employed an older‑era ASIC able to roughly 6 TH/s, submitted shares to CKpool’s solo‑mining infrastructure, and retained the total block reward minus CKpool’s 2% pool payment.
Congratulations to extraordinarily fortunate miner 3K99~Ct8M with solely SIX TH for fixing the 308th solo block at https://t.co/UWgBvLkDqc. A miner of this measurement has solely a a in 180 million likelihood of fixing a block every day! https://t.co/Jx3fTUlaIe pic.twitter.com/F5CKVrEfYtNovember 21, 2025
Headline‑grabbing payout apart, the miner’s win exhibits how uncommon solo mining has grow to be for small operators. With community issue and mixture hash‑energy climbing steadily, the possibility of a tiny miner fixing a block with out important scale is vanishingly small. In sensible phrases, working at 6 TH/s in a sea of a whole lot of exahashes is akin to purchasing one lottery ticket in a contest the place billions of tickets are already in play.
CKpool’s mannequin permits hobbyists to aim solo mining whereas routing their work by way of the pool’s infrastructure. It gives a light-weight setup that connects miners to the Bitcoin community with out requiring them to run a full node or handle their very own backend. Meaning they protect solo‑reward possession relatively than sharing a reward throughout many contributors as occurs in commonplace pooled mining.
For this miner, the selection paid off. That mentioned, the economics of solo mining stay difficult. Working ASIC {hardware} and paying for electrical energy and cooling make solo success a extremely speculative endeavour or, finally, of venture.
This newest win marks the 308th block mined by way of CKpool for the reason that software program’s launch in 2014, and the primary in a number of months. Moments like this can grow to be all of the extra uncommon because the Bitcoin community’s complete hash price continues to climb. They are going to all the time be mathematically potential, nevertheless, and for some, that’ll probably be purpose sufficient to proceed hashing away.
