Bitcoin solo mining produced a remarkable cluster of wins this week: three blocks attributed to NiceHash EasyMining landed within roughly 22 hours on September 25 and 26, delivering a combined 9.4474 BTC in block rewards and fees.

Three Bitcoin blocks in less than a day

On-chain tracking records block 968,495 at 04:12 UTC on September 25 with a 3.1336 BTC reward. Block 968,528 followed at 08:47 UTC with 3.1587 BTC. Then block 968,621 arrived at 02:18 UTC on September 26 with 3.1551 BTC.

The three rewards total 9.4474 BTC. The block records identify NiceHash EasyMining through coinbase tagging and independently point readers to public block explorers for verification.

This was industrial-scale solo hashing, not a desktop miner

The word “solo” can be misleading. Solo mining describes the payout structure, not necessarily the physical size of the mining operation. The tracked hashrate associated with these finds was around 4 EH/s, an industrial quantity of SHA-256 compute rather than a single Bitaxe or home ASIC.

At that scale, the tracker estimates a block interval of roughly two days over the longer sample. Getting three blocks so close together is still a vivid demonstration of Bitcoin mining variance: even with enormous hashrate, block discovery is probabilistic rather than scheduled.

That distinction matters as BitcoinVersus.tech follows both ends of mining hardware, from open-source Bitaxe hardware to 600 TH/s industrial ASICs.

Difficulty makes the streak more notable

These blocks were mined at a Bitcoin network difficulty of approximately 132.76 trillion. BitcoinVersus.tech recently examined why 132.76T difficulty makes ASIC efficiency increasingly important and how public miners account for a substantial share of network hashrate.

Higher difficulty means more expected hashing work per valid block. It does not prevent a miner from finding several blocks rapidly; it changes the probability distribution around how much work is expected before a qualifying SHA-256 hash appears.

Solo mining keeps the entire block reward

Traditional pool mining smooths variance by combining many miners’ hashrate and distributing earnings according to contributed work. A solo-style product instead exposes the participant to much larger variance: long periods can produce nothing, but a successful block can deliver the block subsidy and transaction fees according to the service’s terms.

That lottery-like distribution is one reason home solo mining has remained culturally important even while industrial mining has scaled into hundreds of megawatts. BitcoinVersus.tech has covered NerdMiner education, the open-source Zyber 8 Bitaxe, and changes in mining-pool infrastructure.

The blockchain is the final proof

Unlike an estimated profitability screenshot, a valid Bitcoin block is publicly auditable. Its header, proof of work, transactions, coinbase data and reward can be checked independently. The tracker links each win to multiple explorers, allowing the block records to be cross-checked rather than accepted as a marketing claim.

The September streak therefore offers a useful mining lesson beyond the headline number: hashrate buys probability, not certainty. Difficulty sets the network-wide target, ASICs perform the attempts, and eventually one hash lands below that target.

BitcoinVersus.Tech Editor’s Note: “Solo” here refers to the block-reward model associated with NiceHash EasyMining. The observed hashrate is industrial scale and should not be interpreted as evidence that a single consumer ASIC found all three blocks.
