Solo mining sounds like a fantasy until a 15-watt board on someone’s bookshelf finds an entire Bitcoin block. Then it stops being a fantasy and starts being a documented event with a block height you can look up. This page exists to keep that record: every confirmed solo block found by a Bitaxe or comparable open-source miner, the math behind why it’s possible, and what your own odds actually look like. No hype, no rounding in our favor — just the running tally and the probability that makes it real.
Last updated: May 2026. This is a living reference — block wins are added as they’re confirmed with verifiable on-chain proof.
What a Bitaxe actually is — and why a block win is even possible
Get the hardware right first, because the entire story depends on it. A Bitaxe is a fully open-source, single-board Bitcoin ASIC miner. It draws around 15 watts — less than a household lightbulb — and it is not a space heater, not a refurbished industrial unit, and not a hobby toy that “kind of” mines. It runs a real SHA-256 ASIC, connects to a pool over WiFi via an ESP32-S3 microcontroller, and is managed through the web-based AxeOS firmware (see our AxeOS complete guide).
The board generations run Max → Ultra → Supra → Gamma, each adopting a newer Bitmain ASIC. D-Central tracks the real specs in our miner database:
| Model | Chip | Hashrate | Power | Notes |
|---|---|---|---|---|
| Bitaxe Ultra | BM1366 (single) | ~500 GH/s | ~15 W | The original open-source solo miner. Quiet enough for a bookshelf. |
| Bitaxe Supra | BM1368 (single) | ~600 GH/s | ~15 W | Uses the S21-generation chip. 5 V barrel-jack power. |
| Bitaxe Gamma | BM1370 (single) | ~1.2 TH/s | ~15 W | Latest single-chip board — roughly double the older models’ hashrate. |
| Bitaxe Hex | BM1366 ×6 | ~3 TH/s | ~90 W | Six-chip board for serious solo miners, still home-friendly. |
| Bitaxe GT | BM1370 ×2 | ~2.15 TH/s | ~35-43 W | Dual-chip board (Gamma Turbo) — best hashrate-per-watt in the Bitaxe lineup, ~18 J/TH. |
Here’s why a block win is mathematically possible at all: Bitcoin doesn’t award blocks to “big miners.” It awards them to whoever finds a valid hash first. Every hash your Bitaxe computes is a lottery ticket against the same target every machine on Earth is racing. Your probability of finding any given block is simply your hashrate ÷ total network hashrate. That number is tiny. It is not zero. And “not zero” is the whole point.
D-Central is a pioneer manufacturer in this ecosystem — we built the original Bitaxe Mesh Stand and developed the heatsinks for the Bitaxe and Bitaxe Hex. We have a stake in this story being told accurately.
Confirmed Bitaxe solo block wins
The running record. Every entry below is a solo block reported as found by a Bitaxe or comparable single-board open-source miner. Block heights are verifiable on any block explorer.
| Date | Block height | Miner | Approx. hashrate | Pool | Notes |
|---|---|---|---|---|---|
| July 24, 2024 | 853,742 | Bitaxe Ultra (BM1366) | ~480 GH/s | Public Pool | The first widely-reported Bitaxe solo block — the event that turned solo mining from theory into a movement. |
| October 2024 | 868,790 | Bitaxe Gamma (BM1370) | ~1.2 TH/s | Public Pool | Second confirmed Bitaxe block win, on a single-chip Gamma board. |
Know of a Bitaxe block win we haven’t logged — with a verifiable block height and pool record? Contact D-Central and we’ll verify and add it. We’d rather this list be short and accurate than long and wrong.

The probability math — your real odds, model by model
This is the part most coverage skips, because the honest numbers are humbling. They’re also the most important thing on this page. The figures below assume a global network hashrate of roughly 800 EH/s (early 2026). Solo mining is memoryless — finding a block doesn’t make the next one likelier, and a long dry spell doesn’t make you “due.” Every block is an independent roll.
| Miner | Hashrate | Share of network | Average time to find a block* | Probability in 1 year |
|---|---|---|---|---|
| Bitaxe Ultra | 500 GH/s | ~0.0000000625% | ~1,600 years | ~0.06% |
| Bitaxe Supra | 600 GH/s | ~0.000000075% | ~1,330 years | ~0.075% |
| Bitaxe Gamma | 1.2 TH/s | ~0.00000015% | ~665 years | ~0.15% |
| Bitaxe Hex | 3 TH/s | ~0.000000375% | ~265 years | ~0.38% |
| Bitaxe GT | 2.15 TH/s | ~0.000000269% | ~370 years | ~0.27% |
*Average — not a countdown. “1,600 years on average” means a Bitaxe Ultra could find a block tomorrow or never. Both confirmed wins above came from miners whose “average” was centuries away. That’s not a contradiction; that’s exactly how a lottery works.

The swarm effect: why every Bitaxe matters even if yours never wins
Here’s the reframe that makes individual odds beside the point. There are tens of thousands of Bitaxe miners running worldwide. Each one is a tiny independent lottery ticket — but collectively, the Bitaxe “swarm” represents a real, growing slice of hashrate that is not controlled by the handful of large pools that dominate the network. Every Bitaxe pointed at a solo pool is a node of hashrate that chooses its own destiny.
When one of those tickets hits, the entire block reward goes to one person — not split, not pooled. But the deeper win is structural: more Bitaxe units means hashrate distribution gets less concentrated, and a less concentrated network is a harder network to coerce. That’s the actual product here. The block win is the headline; decentralization is the story. Our piece on why solo mining matters goes deeper on that.
How to take your own shot
- Pick a model. More hashrate buys better odds, but all of them are valid lottery tickets. The Bitaxe Buying Guide walks through Ultra vs. Supra vs. Gamma vs. the multi-chip Hex and GT.
- Order from a pioneer. Get your Bitaxe, Bitaxe GT, or Bitaxe Hex from D-Central, plus a proper stand and heatsink.
- Set it up. Follow the Bitaxe setup guide for your model — note the power detail from our database: single-board Bitaxe units run on a 5 V barrel jack, and USB-C is for firmware only.
- Point it at a solo pool. Public Pool and solo.ckpool.org are the common choices. Solo means you’re racing for the whole block, not a payout share.
- Let it run. Solo mining is set-and-forget. Your board hashes 24/7 in the background, drawing about as much power as a nightlight.
- Optionally, tune it. The Bitaxe overclocking guide covers squeezing out extra hashrate — and the heat and stability trade-offs that come with it.
Frequently asked questions
Has a Bitaxe really mined a full Bitcoin block?
Yes. The table above lists confirmed solo blocks found by single-board Bitaxe miners, each with a verifiable block height. The first widely-reported one was block 853,742 in July 2024, found by a Bitaxe Ultra hashing around 480 GH/s on Public Pool.
What are my odds of finding a block with a Bitaxe?
Very small — a Bitaxe Ultra averages roughly one block every 1,600 years against the current network. But “average” is not “guaranteed,” and both confirmed wins so far came from miners whose statistical average was centuries out. Use the solo mining calculator for live numbers on your specific model.
Is a Bitaxe a space heater?
No. A Bitaxe draws about 15 watts — it produces a negligible amount of heat. It’s a solo lottery miner, not a heating appliance. D-Central’s actual heating products are full-ASIC builds like the Bitcoin Space Heater Editions and the BitChimney. Don’t confuse the two — they’re different machines for different jobs.
Which Bitaxe gives the best chance of a block win?
More hashrate means better odds, so the dual-chip Bitaxe GT (~2.15 TH/s) leads, followed by the six-chip Bitaxe Hex (~3 TH/s aggregate). Among single-chip boards, the Bitaxe Gamma (~1.2 TH/s) is the strongest. But every model is a real ticket — both confirmed wins came from boards in the sub-1.5 TH/s range.
Your board could be the next entry on this page
The math doesn’t care how small your miner is — it only cares that it’s hashing. Two confirmed wins are already on the record, and the swarm keeps growing. Start with the Bitaxe Hub for the complete resource center, dig into the strategy in Solo Mining: The Complete Guide, or just pick up a Bitaxe and take your shot. Every hash counts. Every miner matters.
