Bitaxe Block Wins Tracker: Every Solo Block Found

The Improbable Phenomenon: Bitaxe Solo Block Wins

On July 24, 2024, something happened that the probability calculators said should take thousands of years. A single Bitaxe Ultra — a hand-sized, open-source Bitcoin miner producing roughly 500 GH/s — solved Bitcoin block #853,742 on Solo CKPool and claimed the full block reward of 3.15 BTC, worth approximately $206,000 at the time.

The odds? Approximately 1 in 1.1 billion per block interval. The network hashrate at the time exceeded 550 EH/s. That Bitaxe Ultra represented roughly 0.0000000009% of the total network hashrate. And yet, the Bitcoin protocol does not care how large or small you are. One hash is all it takes.

That moment electrified the entire Bitcoin mining community. It proved what solo miners had always believed: that on this network, the rules are the same for everyone. Since then, multiple Bitaxe and open-source mining devices have found blocks, and every single one has been celebrated as a victory for decentralization itself.

This article tracks every known Bitaxe and open-source miner solo block win. We will keep it updated as new blocks are found — because the next one could be yours.

How a Tiny Miner Can Find a Bitcoin Block

To understand why these block wins matter, you need to understand how Bitcoin mining actually works at the protocol level.

The Hash Lottery

Every 10 minutes (on average), the Bitcoin network produces a new block. To produce that block, miners must find a hash — a SHA-256 output — that falls below a target difficulty threshold. This is pure brute-force computation: try a nonce, hash the block header, check if the result meets the target. If not, increment the nonce and try again. Trillions of times per second, across millions of mining machines worldwide.

The critical insight: every single hash attempt has an equal, independent probability of being the winning hash. It does not matter whether that hash comes from a 500 EH/s mining farm or a single Bitaxe on your desk. Each hash is a fresh lottery ticket. The farm just buys more tickets per second.

The Math of Solo Mining

With a Bitaxe Supra running at approximately 500 GH/s (0.0005 TH/s) against a network hashrate of 700 EH/s (700,000,000 TH/s), your share of the total network hashpower is:

0.0005 / 700,000,000 = 0.000000000000714 (roughly 1 in 1.4 trillion)

With about 144 blocks mined per day, your expected time to find a block solo is measured in tens of thousands of years. But “expected time” is an average — it is a statistical distribution with a long tail. Some miners will wait forever. Some will find a block on their first day. The probability of finding a block within any given year with a single Bitaxe Supra is approximately 0.005% — tiny, but definitively not zero.

More powerful Bitaxe models improve these odds proportionally. A Bitaxe Gamma at 1.2 TH/s doubles the probability compared to a 600 GH/s Supra. A Bitaxe GT at 2.15 TH/s roughly quadruples it. And miners running clusters of multiple Bitaxe units multiply their chances further. But even the most optimized Bitaxe setup is still playing a long-odds game — which is precisely what makes every block win extraordinary.

Every Known Bitaxe and Open-Source Miner Solo Block Win

The following table documents every confirmed solo block win by a Bitaxe or comparable open-source mining device. All of these miners were connected to Solo CKPool or Public Pool, which are solo mining pools that route work to individual miners without splitting rewards.

* Block #913,272 was mined through Ocean Mining pool, so the reward was distributed proportionally among pool participants rather than as a full solo reward. It is included here because the submitting device was a NerdQAxe++ open-source miner.

This table is updated as new block wins are confirmed. If you have documentation of a Bitaxe or open-source miner block win not listed here, contact us.

Notable Additional Solo Miner Wins

Beyond Bitaxe-specific wins, the broader solo mining community using small-scale hardware has also seen remarkable successes:

Solo CKPool data shows approximately 22 verified solo blocks mined over a rolling 12-month period by small-scale miners, with an average interval of about 15.6 days between wins. The phenomenon is not a fluke — it is a statistical certainty that some fraction of small miners will hit blocks, and the open-source mining movement is ensuring more of those miners are running hardware they built, configured, and control themselves.

Block #853,742: The One That Started It All

The first Bitaxe block deserves its own section because of the magnitude of what it represented.

At 11:43 AM UTC on July 24, 2024, a Bitaxe Ultra mining through Solo CKPool submitted a valid proof-of-work for block #853,742. The block contained 4,353 transactions moving a total of 2,652 BTC (worth roughly $177 million at the time). The miner received the full post-halving block subsidy of 3.125 BTC plus approximately 0.025 BTC in transaction fees.

The device that found this block was roughly the size of a human hand. It was consuming approximately 12 watts of power — less than a household LED bulb. The Bitcoin network’s total hashrate at the time was approximately 551 EH/s, making the Bitaxe Ultra’s 500 GH/s contribution about one billionth of the total network power.

The news spread across Reddit, X (formerly Twitter), BitcoinTalk, and every mining community within hours. It was covered by mainstream crypto media outlets worldwide. Not because the block itself was unusual — but because of who found it and what they were using.

The message was unmistakable: Bitcoin mining is still permissionless. You do not need a data center. You do not need an institutional mining contract. You need a Bitaxe, an internet connection, and the belief that your next hash might be the one.

Block #887,212: The Cluster Win

On March 10, 2025, a solo miner running a cluster of six Bitaxe devices with a combined hashrate of approximately 3.3 TH/s solved block #887,212 through Solo CKPool. The reward was 3.15 BTC, worth roughly $258,000.

This win demonstrated an important strategy: running multiple Bitaxe units in parallel linearly multiplies your odds. Six units producing 550 GH/s each give you six times the probability of a single unit — still infinitesimal against the network, but measurably better. This miner took the DIY approach to its logical conclusion: a small fleet of open-source miners, each costing a fraction of a commercial ASIC, collectively buying more lottery tickets per second.

The block contained over 3,500 transactions and was validated by the network without issue. The mining community celebrated it as the “David vs. Goliath” moment — a title that news outlets literally used in their coverage.

Block #889,975: The Stock Gamma Win

Just two weeks after block #887,212, on March 23, 2025, a stock Bitaxe Gamma running at 1.2 TH/s with 18W power draw captured block #889,975 and earned 3.149 BTC. The block was relatively light — 1,610 transactions — making it the fourth solo win confirmed in March 2025 across all solo mining pools.

What made this win particularly notable was that the Bitaxe Gamma was running completely stock. No overclock, no cluster, no tricks. A single unit out of the box, doing exactly what it was designed to do: hash and hope. March 2025 became a watershed month for solo mining, with multiple small-scale miners finding blocks in rapid succession.

What Happens When You Find a Block

For anyone running a Bitaxe connected to Solo CKPool or a similar solo mining pool, here is exactly what happens when lightning strikes:

The Technical Process

1. Your Bitaxe computes a valid hash: The ASIC chip generates a SHA-256 hash of the block header that falls below the current difficulty target
2. The hash is submitted to the pool: Solo CKPool receives your valid share and recognizes it as a block solution
3. The pool broadcasts the block: Solo CKPool (or your chosen pool) broadcasts the solved block to the Bitcoin network
4. Network validation: Other nodes verify the block and add it to their copy of the blockchain
5. Coinbase reward assigned: The block subsidy (currently 3.125 BTC) plus all transaction fees in the block are assigned to the Bitcoin address you configured in your mining pool settings
6. 100-block maturation: The coinbase reward requires 100 confirmations (approximately 16.7 hours) before it can be spent — this is a Bitcoin protocol rule to handle chain reorganizations

The Community Celebration

When a Bitaxe or open-source miner finds a block, the community response is immediate and euphoric. Screenshots of AxeOS dashboards, Solo CKPool confirmations, and mempool.space block explorers get shared across every platform. The miner (often anonymous) receives congratulations from thousands of strangers who see the win as a win for all of them.

This is not just sentimentality. Every block found by a small, independent miner is a concrete demonstration that Bitcoin’s proof-of-work consensus is functioning as designed — that the network is not solely the domain of industrial operations. It is evidence that the hash lottery is fair, and that decentralization is not just a talking point but a measurable reality.

Tax Implications

A block reward is generally treated as income in most jurisdictions, valued at the fair market price of Bitcoin at the time the block is found. In Canada and the US, this means the reward is taxable income. Consult a tax professional familiar with cryptocurrency mining — the specific treatment varies by jurisdiction. The important point: if you find a block, plan for the tax liability alongside the celebration.

Probability Analysis: Your Realistic Odds

Let us put real numbers on the odds. The following table shows the probability of finding at least one block in various time periods, assuming a constant network hashrate of 700 EH/s and 144 blocks per day.

These numbers are humbling. Even running a fleet of Bitaxe devices 24/7 for a year, your probability of finding a block remains a fraction of a percent. But here is the thing: these are non-zero probabilities operating over an infinite time horizon. Bitcoin will keep producing blocks every 10 minutes, and every single one of those blocks has a winner. With enough small miners in the global pool of hashers, some of them — against all mathematical expectations for any individual — will win.

As the confirmed block wins above demonstrate, reality does not always follow the expected average. Probability does not promise when; it only promises that the chance exists.

Why Solo Block Wins Matter for Decentralization

Every Bitaxe block win carries significance far beyond the individual miner’s reward. Here is why these events matter at the network level:

Proof That Mining Remains Permissionless

Bitcoin’s entire security model depends on the assumption that anyone can mine. When only industrial operations find blocks, that assumption weakens — not technically, but perceptually. Every solo block win is proof that the protocol’s promise holds: one hash, one chance, no permission required.

Geographic Hash Rate Distribution

Industrial mining tends to concentrate in regions with the cheapest electricity — often a handful of countries or states. Solo miners with Bitaxe devices are distributed across the globe: in Canadian basements, American garages, European apartments, and everywhere in between. Every hash they produce adds to the geographic diversity of the network, making Bitcoin more resilient to regional disruptions, regulations, or attacks.

Reducing Pool Concentration

When solo miners connect to Solo CKPool or run their own nodes, they are not contributing hashrate to the major mining pools (Foundry, AntPool, F2Pool) that already control the majority of blocks. This directly reduces mining pool concentration — one of the most discussed centralization vectors in Bitcoin today.

The Cultural Signal

Perhaps most importantly, solo block wins sustain the narrative that Bitcoin belongs to individuals, not institutions. They inspire new miners to set up their first Bitaxe. They remind the community why decentralization matters. They are the stories that get shared, celebrated, and remembered — because they embody the original spirit of Bitcoin: a system where anyone can participate on equal terms.

Getting Started with Solo Mining

If these block wins have inspired you to try solo mining, here is the path:

1. Choose your Bitaxe model: Review our Bitaxe Buying Guide to find the right model for your budget and goals. Higher hashrate models like the Bitaxe GT or Bitaxe Hex increase your probability proportionally.
2. Set up your device: Follow the model-specific setup guide — Supra, Gamma, GT, or Hex.
3. Configure for solo mining: Point your Bitaxe to Solo CKPool (solo.ckpool.org) or Public Pool (public-pool.io) with your Bitcoin address. This ensures that if you find a block, the full reward goes to you.
4. Optimize your setup: Upgrade your cooling with a D-Central heatsink and Mesh Stand, then consider a careful overclock using our Overclocking Manual. Every extra hash per second improves your odds.
5. Let it run: Solo mining is a patience game. Set it, monitor it, maintain it, and let probability do its work. Your Bitaxe does not need to be fast — it needs to be running.

The Economics of Solo Mining vs. Pool Mining

A natural question: should you solo mine or join a pool?

Pool Mining

In a mining pool, your Bitaxe contributes shares alongside thousands of other miners. When the pool finds a block, the reward is split proportionally by contribution. With a Bitaxe, your share of each block is microscopic — fractions of a satoshi — but you receive consistent, predictable payouts. Over time, your earnings converge on your proportional share of network rewards.

Solo Mining

Solo mining is all-or-nothing. You either find a block and receive the full 3.125+ BTC reward, or you receive nothing. Mathematically, over an infinite timeframe, the expected value is the same as pool mining. But the variance is extreme: you could mine for 100 years and never find a block, or you could find one tomorrow.

The Bitaxe Philosophy

Most Bitaxe miners choose solo mining not for the expected return but for the principle and the possibility. A Bitaxe running at stock settings consumes 12-18W of power — roughly $15-30 per year in electricity. At that cost, solo mining is less an investment strategy and more a statement: you are contributing to network decentralization, running your own lottery ticket, and participating in Bitcoin at the most fundamental level.

The miners who found the blocks listed in our tracker above were not running profitability spreadsheets. They were running Bitaxe devices because they believe in what Bitcoin represents. The block rewards were life-changing bonuses on top of that conviction.

Building a Solo Mining Strategy: Maximizing Your Odds

While solo mining with a Bitaxe is inherently a long-odds proposition, there are ways to tilt the probability in your favor:

Run More Units

Probability scales linearly with hashrate. Three Bitaxe Gamma units give you three times the odds of one. If budget allows, a small fleet of Bitaxe devices running on individual Mesh Stands is the most accessible way to multiply your chances.

Overclock Responsibly

A well-cooled, properly overclocked Bitaxe Gamma can push from 1.2 TH/s to 1.6-1.8 TH/s, significantly improving your odds at the cost of additional power consumption. See our Overclocking Manual and invest in proper cooling accessories first.

Maximize Uptime

Every minute your Bitaxe is offline is a minute you cannot find a block. Use a UPS (uninterruptible power supply) for protection against power outages. Configure AxeOS to auto-restart after power restoration. Monitor your device remotely and address issues quickly.

Choose the Right Pool

For true solo mining, use Solo CKPool (solo.ckpool.org) — it routes block templates to your miner and pays the full reward if your miner finds the solution. Public Pool (public-pool.io) is another option that is popular in the Bitaxe community. Both are designed specifically for solo miners and do not split rewards across participants.

Frequently Asked Questions

Every Hash Counts

The block wins documented on this page are not anomalies to be dismissed. They are evidence of a fundamental truth about Bitcoin: that the protocol treats every hash equally, regardless of who produced it or what hardware generated it.

Every Bitaxe running in a Canadian basement, every NerdAxe humming on a desk in Texas, every open-source miner plugged into a solar panel in Germany — they are all participants in the most decentralized, permissionless monetary network ever created. Most will never find a block. But every single one contributes to the security, distribution, and resilience of that network.

D-Central has been a pioneer in the Bitaxe ecosystem since the very beginning. We stock every Bitaxe model, manufacture the accessories that keep them running at peak performance, and build the guides that help miners succeed. Because we believe that decentralization is not just a feature of Bitcoin — it is the feature. And every hash contributes to it.

The next block could be found by anyone. Including you.
