Two Solo Bitcoin Blocks Paid About $476,000 in Seven Hours

By Elena Vasquez

Two solo Bitcoin miners collected an estimated $476,000 in gross block rewards for finding blocks roughly seven hours apart, a development shared by Bitcoin developer Mononaut on X. Mempool records attributed both blocks to “Solo CK,” while one paid 3.1335 BTC in rewards, valued at more than $237,000.

How much did the miners receive?

The report described the two-block reward, including fees, as “approximately 6,276 BTC” and about $476,000. Those figures do not reconcile literally: 6,276 BTC is 1,000 times 6.276 BTC. The first block alone paid 3.1335 BTC, making 6.276 BTC the coherent reading despite the unexplained comma.

On that basis, the $476,000 total was about twice the first block’s value; an even split averages $238,000 per miner. The source gave no second-block breakdown or operating costs, so this remains a gross reward rather than a verified net profit. In plain terms, the headline figure was paid out, not earned after expenses.

The arithmetic also narrows the second block’s likely payout. If the first produced more than $237,000 and the pair brought $476,000, the other reward would sit near $239,000. That figure is a residual calculation, however, rather than a payout the source directly reports.

What did the first block show?

Block number 974,893 appeared at 07:51 Turkish time and contained 3,955 transactions. Its 3.125 BTC base reward plus approximately 0.0085 BTC in transaction fees produced 3.1335 BTC, which the report valued at more than $237,000.

The fee component represented about 0.27% of the first block’s total, calculated from the reported figures. That leaves nearly all of the payment tied to the base reward rather than transaction fees. For readers, fees added only a fraction of a percent to the first payout.

The block number and transaction count provide concrete identifiers for checking the first discovery. The source did not provide hash-rate estimates, so it cannot establish how unusual either discovery was or what computational effort produced it. The verified point is narrow: the first block paid 3.1335 BTC, including about 0.0085 BTC in fees.

What does Solo CK attribution establish?

Mononaut, a Bitcoin developer, surfaced the event on X. The report described the finds as solo CKPool activity, while Mempool records identified the generator on both blocks as “Solo CK.”

The available account did not reproduce Mononaut’s post, so it supplied no verbatim quotation or additional technical context to verify. The recorded label establishes block-generation attribution, not the miners’ identities, locations or control arrangements.

The source treats them as two solo miners but provides no ownership data, so readers should not equate the shared label with common ownership. For readers, “Solo CK” identifies the recorded source, not the people behind it.

What remains unverified?

The source provides detailed figures only for the first block. It omits the second block’s number, exact time, transaction count, fee amount and standalone payout, which prevents a full reconciliation of the combined reward.

It also gives no mining hardware, electricity arrangements or evidence that the two miners acted independently. The phrase “today” appears without a calendar date, further limiting independent timing checks.

For miners, a block reward is not the same as recurring monthly revenue. Without hash rate, uptime and cost data, no reliable earning rate can be inferred. For readers, $476,000 is the reported gross payout, not an audited profit figure.

What comes next?

The episode establishes two confirmed Solo CK blocks and roughly $476,000 in gross payouts, not a demonstrated durable shift in Bitcoin’s mining structure. When Solo CK next appears in a block, that attribution will provide the near-term test of whether the seven-hour pair was repeatable discovery or an isolated concentration of rewards.
