Block 913,272 — solo-mined on 5 Sep 2025
OCEAN (DATUM) · 3.1341 BTC
Bitcoin block 913,272 was solo-mined on 5 September 2025 on OCEAN (DATUM), for a block reward of 3.1341 BTC. It is one of the 40 blocks in the Solo Block Record, every one verified on the chain itself.
The first block ever found by NerdQAxe++ hardware, hashing through OCEAN's DATUM. Because OCEAN is not a pure solo pool, the finder received a proportional payout rather than the whole coinbase — the silicon still did the thing.
Included for the hardware milestone; the payout followed OCEAN's reward model, not finders-keepers.

The odds
At that day's difficulty, a rig this size expected one block every 3,900 years — about 1 in 1,400,000 on any given day.
That is the one formula behind every odds line in the record: the network difficulty at that height, times 2³², divided by the reported hashrate — the expected time between blocks for that rig. Odds like these are why solo mining is a lottery, not a paycheck. Run the same math for your own hardware on the odds calculator.
