One unknown Bitcoin miner found 4 blocks in ~20 hours — solo miner or something else?

Hi guys,

I noticed something pretty unusual while looking through Bitcoin block data.

The same Bitcoin address received the coinbase rewards from four blocks mined within roughly 20 hours and 9 minutes:

• 2026-10-23 05:12:20
• 2026-10-23 10:53:46
• 2026-10-23 11:43:51
• 2026-10-24 01:21:17

All four coinbase transactions paid to the same address:

The rewards were approximately 3.13 BTC each, totaling approximately ~12 BTC.

I also noticed an earlier block reward paid to the same address on October 22, at 02:10:14, bringing the total to five block rewards associated with this address in roughly 47 hours.

The blocks were labeled as mined by an unknown miner. Obviously, that label alone doesn't prove that this was a solo miner, and the address itself doesn't establish who actually mined the blocks.

Still, the timing caught my attention. Finding multiple blocks in such a short period seems like an interesting statistical event, especially if this really was an independent miner rather than a mining pool or shared infrastructure.

Here is the link to the address on mempool.space:

Here are my questions:

• Does anyone recognize this address or know whether it is associated with a known mining pool?
• Could someone do some on-chain analysis of this address please?
• Given the Bitcoin network's total hashrate around those dates, how statistically unlikely would this pattern be for a genuine solo miner?
• Is there a way to establish whether these blocks were mined by the same physical machine or operator?

Thanks for answers!
