Short Answer: Yes. As of November 2025, open-source home mining hardware has mined at least five confirmed Bitcoin blocks. Three of those blocks were solved by Bitaxe devices and two by NerdQaxe++ miners. Combined payouts exceed $1 million in BTC rewards. This article documents every confirmed block find with exact dates, block heights, hardware specs, mining pools, and payout values. Read on to learn how tiny home miners keep defying billion-to-one odds and how you can start mining today.
Every Confirmed Open-Source Home Miner Block Find
The table below summarizes every confirmed Bitcoin block mined by open-source home mining hardware through November 2025. Each entry represents a moment where a device small enough to sit on a desk competed against warehouses full of industrial ASICs and won. The hardware column lists the device that submitted the winning hash, while the hashrate column reflects the total setup used by the operator.
| Block Height | Date | Hardware | Total Setup Hashrate | Pool | Reward |
|---|---|---|---|---|---|
| #853,742 | July 24, 2024 | Bitaxe Supra | ~500 GH/s | Solo CKPool | ~3.15 BTC (~$200K) |
| #887,212 | March 10, 2025 | Bitaxe Ultra (6-unit cluster) | ~3.3 TH/s | Solo CKPool | ~3.15 BTC (~$250K) |
| #913,272 | September 5, 2025 | NerdQaxe++ | ~4.8 TH/s | Ocean Mining (DATUM) | Proportional pool payout |
| #920,440 | October 27, 2025 | NerdQaxe++ Rev 6 (cluster) | ~130 TH/s | Self-hosted Public Pool (Umbrel) | ~3.15 BTC (~$342K) |
| #924,569 | November 21, 2025 | Bitaxe Gamma 602 (6-unit cluster) | ~5.4 TH/s | Solo CKPool | ~3.08 BTC (~$266K) |
Five blocks in under eighteen months is remarkable. Several of these wins came from setups hashing at single-digit terahashes per second against a Bitcoin network exceeding 1 Zetahash (1,000,000 TH/s). The statistical odds of any individual win were measured in the billions-to-one, yet the growing global fleet of open-source home miners keeps beating them.
Block #853,742 – July 24, 2024 (Bitaxe Supra)
The open-source mining community’s first major victory came on July 24, 2024. A solo miner running a single Bitaxe Supra at approximately 500 GH/s mined Bitcoin block #853,742 through Solo CKPool. This was the first-ever Bitcoin block solved by a Bitaxe home miner, and the news spread across social media within minutes.
The block was mined at roughly 11:43 AM UTC and yielded the full block subsidy of 3.125 BTC plus approximately 0.025 BTC in transaction fees, totaling about 3.15 BTC. At Bitcoin’s price on that date, the payout was worth over $200,000. For a device that costs roughly $130, the return was extraordinary.
To understand the scale of this achievement, consider the math. The total Bitcoin network hash rate in mid-2024 was on the order of 600 EH/s (6 × 10^20 hashes per second). The Bitaxe Supra contributed roughly 500 GH/s (5 × 10^11 hashes per second). That gave the miner approximately a 1-in-1.1-billion chance of solving any given block, which translates to an expected wait of thousands of years.
Analogy: Finding a block with a single Bitaxe is like holding one ticket in a raffle drum containing over a billion entries and having your number called. The first Bitaxe block proved that lottery mining with home hardware was not just theoretical. It was real, documented, and recorded on the Bitcoin blockchain permanently.

Block #887,212 – March 10, 2025 (Bitaxe Ultra Cluster)
Lightning struck again on March 10, 2025. Another solo miner using Bitaxe hardware solved Bitcoin block #887,212 through Solo CKPool. The winning hash was submitted by a Bitaxe Ultra contributing around 480 GH/s of individual hashrate, but the operator’s full setup was more sophisticated than a single device.
The miner was running a cluster of six Bitaxe devices with a combined hashrate of approximately 3.3 TH/s. This DIY approach of stacking multiple open-source miners linearly increased the operator’s odds. As Solo CKPool administrator Con Kolivas confirmed at the time, total hashpower is what matters for your odds and running more devices linearly increases your chances.
The block reward totaled approximately 3.15 BTC (3.125 BTC subsidy plus ~0.025 BTC in fees), worth roughly $250,000 at the time. Even with 3.3 TH/s, Kolivas estimated the miner’s probability at less than 1 in a million per day, translating to an expected wait of approximately 3,500 years. The fact that it happened just 229 days after the first Bitaxe block proved the initial win was no statistical anomaly.
Block #913,272 – September 5, 2025 (NerdQaxe++ on Ocean Pool)
A NerdQaxe++ submitted the winning hash for Bitcoin block #913,272 on September 5, 2025. This was the first confirmed block find by a NerdQaxe++ miner. However, because the operator was mining through Ocean Mining’s pool rather than solo mining, the block reward was split proportionally among all pool participants. The miner did not receive the full 3.125 BTC subsidy.
The operator was using Ocean’s DATUM protocol paired with a Start9 home server running a full Bitcoin node. DATUM lets miners construct their own block templates and select which transactions to include, which is a meaningful step toward decentralization even within a pool setting. Network difficulty at block 913,272 stood at approximately 136.04 T, and at the NerdQaxe++ default hashrate of 4.8 TH/s the expected time to find a block solo would be about 4,145 years.
The block was recorded and confirmed on-chain, and key OSMU developers including Bitaxe creator Skot amplified the news across social media. While the payout was only a fraction of the full block reward, the win proved the NerdQaxe++ platform could compete on the Bitcoin network. Read the full NerdQaxe++ block 913,272 coverage.
Block #920,440 – October 27, 2025 (NerdQaxe++ Rev 6, $342K Solo Win)
A Solo Satoshi customer solved Bitcoin block #920,440 on October 27, 2025, earning approximately $342,000 in BTC, the largest confirmed payout to a home miner using open-source hardware. The customer (who wishes to remain anonymous) reached out to Solo Satoshi directly after the win and shared that the reward would be used to pay off his home. The NerdQaxe++ Revision 6 units used in the winning setup were purchased from Solo Satoshi.
The operator was running a cluster of six NerdQaxe++ units alongside one Canaan Avalon miner, producing a combined hashrate of approximately 130 TH/s. The entire stack pointed at a self-hosted Public Pool instance running on an Umbrel home server. The block’s scriptsig confirmed the setup, reading “Public Pool on Umbrel.” The winning miner submitted a best share near 2.08 petadifficulty during its session.
This block stands out because the operator ran a completely sovereign mining stack. Open-source hardware handled the hashing, a self-hosted pool managed the stratum connection, and a local Bitcoin node validated the block. No third-party pool operator touched the reward. Multiple community posts on Reddit (r/Bitcoin and r/BitAxe) and X confirmed the details, and OSMU developers including Skot amplified the news. Read the full block 920,440 coverage.
Block #924,569 – November 21, 2025 (Bitaxe Gamma Cluster, $266K)
The most recent open-source block find came on November 21, 2025, when a cluster of Bitaxe Gamma miners solved Bitcoin block #924,569 through Solo CKPool. The @solosatoshi account on X broke the news with a post that reached tens of thousands of views, confirming the winning device appeared to be a Bitaxe Gamma hashing at 1.0 to 1.2 TH/s.
CKPool statistics for the winning address (3K99ATGytaz1Ns2xNiJfjQbECz5ewnCt8M) revealed the operator was running six workers, each hashing at 1.0 to 1.2 TH/s, consistent with Bitaxe Gamma 602 hardware. The combined setup hashrate was approximately 5.4 TH/s. The lucky worker achieved a best-ever difficulty of 221.39 T, exceeding the network difficulty at the time of approximately 152 T. The block reward of 3.08349744 BTC was paid directly to the miner’s address, worth approximately $266,000 at Bitcoin’s price that day.
This third Bitaxe block is particularly noteworthy because it was mined by Bitaxe Gamma 602 devices, Solo Satoshi’s current best-selling model. The Gamma runs a single BM1370 ASIC chip at 1.2 TH/s with an efficiency of 15 J/TH, costs approximately $2 per month in electricity, and retails for under $130. Six units represent a total hardware investment of under $800 and a combined electricity cost of roughly $12 per month. Against a network exceeding 1 ZH/s, the odds of this 5.4 TH/s cluster finding a block on any given day were less than 0.001%, yet it happened.
What These Blocks Mean for Home Mining
Five confirmed blocks in eighteen months establishes a clear pattern: open-source home miners are not just participating in Bitcoin’s proof-of-work, they are winning. The acceleration is driven by three compounding factors that will only strengthen over time.
The installed base of Bitaxe and NerdQaxe++ devices is growing rapidly. More than 100,000 Bitaxe units are estimated to be hashing globally as of late 2025, and every additional unit increases the collective probability of finding the next block. Hardware efficiency continues to improve with each new release. The Bitaxe Gamma Duo 650 delivers 1.63 TH/s from two BM1370 chips, and the Bitaxe GT (Gamma Turbo) 801 reaches 2.15 TH/s. Each new model puts more hashrate on more desks around the world.
Miners are also getting more sophisticated in their setups. The block 920,440 win demonstrated a fully sovereign mining stack: open-source hardware, a self-hosted pool, and a local Bitcoin node. The block 913,272 win showed DATUM-based template construction on a Start9 home server. These are Bitcoiners running their own infrastructure and making their own choices about transaction selection, which strengthens the decentralization of the entire network.
The interval between confirmed blocks has shortened noticeably: 229 days between block 1 and block 2, 179 days to block 3, 52 days to block 4, and just 25 days to block 5. This trend reflects the compounding effect of more devices, higher per-unit hashrate, and operators running clusters rather than single units. The home mining flywheel is spinning faster with each win.
How to Improve Your Solo Mining Odds
Every block find listed above shares common elements that improve a home miner’s probability. The first and most impactful strategy is running multiple devices. Four of the five confirmed blocks were mined by operators running clusters of two or more units. Running six Bitaxe Gamma devices instead of one multiplies your odds by six, because total hashrate is the only variable that matters in solo mining probability.
Uptime is the second critical factor. Bitcoin produces a new block approximately every ten minutes, which means 144 opportunities per day. Every minute your miner is offline is a chance you miss. Proper cooling is essential for sustained 24/7 operation. Solo Satoshi publishes a detailed guide on choosing the best cooling solution for your Bitaxe that covers fan upgrades, heatsink options, and ambient temperature management.
Overclocking provides the third edge. Pushing a Bitaxe Gamma from its stock 1.2 TH/s closer to 1.4 or 1.5 TH/s increases your probability proportionally without adding another device. The NerdQaxe++ Rev 6 can exceed 6 TH/s with proper voltage and frequency tuning. Solo Satoshi’s overclocking guide walks through every adjustment step by step.
