  • Speculation flared after two Bitcoin blocks appeared untagged, but NiceHash later confirmed the blocks were mined during internal testing.
  • Claims of a solo Bitcoin mining jackpot faded after NiceHash said block metadata display issues caused the confusion.
  • The brief “Bitcoin lottery” buzz showed how rare solo mining wins continue to spark speculation amid rising network hashrate.

Speculation briefly surged this week after two Bitcoin blocks appeared without visible mining pool identifiers, prompting claims that a solo miner had secured a rare full block reward. The blocks, numbered 932129 and 932167, initially showed no clear attribution on mempool explorers, reigniting the long-standing “Bitcoin lottery” narrative within crypto circles.

The reaction reflected how assumptions can quickly form when block metadata appears incomplete, particularly in an industry where solo mining wins are statistically rare but not impossible. Bitcoin’s network operates as a probability-based system, where individual block discoveries occur independently of prior outcomes.

How the Mix-Up Happened

Attention later shifted when NiceHash was identified as the miner behind both blocks, contradicting early claims of an anonymous solo success. Unlike traditional pools, NiceHash functions as a hashrate marketplace, which can complicate attribution when block data is viewed through public explorers.

The company confirmed that the blocks were produced during internal testing for a forthcoming product, rather than through independent solo mining activity. Because the blocks initially appeared untagged, observers assumed no large operator was involved.

NiceHash Chief Executive Sasa Coh told Cointelegraph that the confusion stemmed from how metadata was displayed rather than any attempt to obscure authorship.

The misconception here is only that the blocks were not labeled by mempool, though they were tagged with NiceHashMining… We did not want to stir up any speculation.

Solo mining remains statistically viable but extremely unlikely on an individual basis, with odds worsening as network hashrate increases. Despite this, verified solo blocks continue to appear periodically due to probability across a large global miner base.
