A solo Bitcoin miner has secured a payout worth $244,920 after discovering a block against hugely demanding odds.
The miner, operating through Braiins Solo, found block 966351 on Thursday and received the full block reward and transaction fees. The payment amounted to 3.147 BTC, ending a wait of almost 40 days since the previous solo-mining success.
Braiins CEO Eli Nagar congratulated the miner on X, writing: “Somewhere, someone’s having a very good day. Congratulations to the miner who just found block 966351 on Braiins Solo. Glad we could be part of it.”
The result highlights the extreme challenge facing individuals trying to mine Bitcoin alone. The network is dominated by major mining pools that deploy vast amounts of computing power continuously.
Foundry, Antpool, F2pool, ViaBTC and Spiderpool regularly find blocks, and the five pools together control 78.31% of Bitcoin’s hashrate. All other participants account for a bit more than 20%.
Solo mining differs from conventional pool mining because the miner does not share the eventual reward with a wider group of contributors. Finding a block means taking the entire payout, but failing to do so brings no partial return.
Members of large pools instead contribute their computing power to a shared operation. When the pool discovers a block, its proceeds are distributed among participants, generally according to the amount of hashrate each supplied. That system offers smaller but more predictable payments instead of the possibility of one substantial prize.
There are two main ways to mine solo. A miner can operate a Bitcoin node, create their own block templates and manage the required infrastructure. In the 2026 mining environment, that represents a significant technical and operational challenge, although it remains possible.
Alternatively, miners can use a specialist service such as Solo CKPool or Braiins Solo. Those services provide much of the supporting infrastructure, including the Stratum server, block-template construction and chain-tip tracking. The miner still supplies their own hashrate and attempts to find a block independently.
The previous solo block was discovered on Aug. 2 at block 960804. That miner received 3.1569 BTC after finding the block through Solo CKPool.
As a result, the last two successful solo-mining attempts have come through different services. For industrial-scale mining businesses, discovering another Bitcoin block is part of their normal operation. For an individual miner, however, a successful find can represent a reward that may take years to arrive.
Block 966351 shows that, despite the scale of the competition and the long periods without success, solo miners can still occasionally claim the full Bitcoin mining payout.
