NiceHash debunks ‘Bitcoin lottery’ speculation over untagged blocks

Speculation flared this week after Bitcoin blocks 932129 and 932167 appeared without pool tags, fuelling claims that a solo miner had hit a rare jackpot.

The excitement centred on assumptions about missing metadata rather than evidence of independent mining activity.

NiceHash later confirmed it mined both blocks during internal testing for a forthcoming product.

The company said it operates as a hashrate marketplace rather than a traditional mining pool, contributing to confusion over attribution.

“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,”

Sasa Coh said.

Coh said the blocks were part of internal testing and declined to share technical details ahead of launch.

“We are working on a new set of products that are going to provide a full suite of functionalities on top of the existing marketplace,”

Sasa Coh said.

Observers noted that block tags are metadata rather than protocol guarantees, leaving room for misinterpretation.
