Your live odds — Avalon Nano 3S
At about 6 TH/s and the current network difficulty of 148.36T, the statistical mean time for a single Avalon Nano 3S to solve a block solo is:
“Avg” is the statistical mean — real luck swings wildly either way, which is the whole point of solo. The numbers move with the network; run your own on the odds calculator.

The short answer
Has an Avalon Nano 3S ever found a block? Yes, once on public record: Bitcoin block 951,771, mined on Braiins Solo at 00:27 UTC on 31 May 2026. The chain confirms the block and its reward, and the pool's own statistics trace the winning share to a worker its owner named as a Nano 3S, running at about 6.7 TH/s. That Nano 3S was reportedly one of 14 Avalon machines mining to the same address, so it is a Nano 3S block on the evidence, but not a lone box beating the odds.
Below: what the block itself records, how the pool's data points to the machine, what is only reported, the Avalon blocks that were not a Nano 3S, and the odds one Nano 3S faces today. Everything here was checked on 8 November 2026.
What the block itself shows
Open block 951,771 on mempool.space and you can check each of these yourself:
- When: 00:27 UTC on 31 May 2026. Some reports say 30 May: in the Americas it was still the evening of the 30th.
- Which pool: the coinbase carries the tag
ckpool/braiinssolo/, and mempool.space labels the block Braiins Solo. - Reward: 3.1404 BTC, the 3.125 BTC subsidy plus 0.0154 BTC in fees.
- Who was paid: 3.1247 BTC, 99.5% of the reward, went to the miner's address. The other 0.5% went to a second address. Braiins says its solo pool keeps 0.5% to credit the authors of the ckpool software it runs, which is why its blocks have two outputs.
What the block cannot tell you is the hardware. Its coinbase holds the pool's tag and the payout addresses, and nothing about the machine that found it. For that you need the pool's own data. The same block is entry 951,771 in our Solo Block Record.
Which machine found it
Braiins Solo publishes statistics for each mining address, including every worker's best share ever. Every share has a difficulty, a measure of how small its hash came out, and a share that reaches the network's difficulty is a block. On the address that block 951,771 paid, one worker's best share is 467,758,285,742,953. That is exactly the difficulty of block 951,771's own hash, so that worker solved the block.
Its owner named it Nano3sC, and it averages about 6.7 TH/s today, close to the 6 TH/s that Canaan rates the Nano 3S at. Keep one limit in mind: a pool stores whatever name a miner types, not the model. So “Nano 3S” rests on that name, that hashrate and the reports below. We found no announcement of the find from Canaan or from Braiins.
A Nano 3S, but not a lone one
The winning share came from one machine, but its owner was mining with many on the same address. GN Crypto (1 June 2026) and DigitalToday (2 June 2026, citing CoinPost) reported 12 Nano 3S and 2 Avalon Mini 3, about 147 TH/s in all. Altair Technology, a Canaan distributor, gave the same mix and 157 TH/s. The pool's statistics for that address still list 13 workers named as a Nano 3S and 2 named as a Mini 3.
That changes the story. Every machine on an address draws in the same lottery, so the whole setup had more than 20 times the chance of a single Nano 3S. The “one in 149 million” in the reports is one 6.68 TH/s device's chance on one block; the address as a whole was nearer 1 in 7 million. So the honest takeaway is not that one box beat impossible odds. It is that a Nano 3S can solve a block, and one did, as part of a bigger home setup.
Avalon blocks that were not a Nano 3S
Canaan makes several Avalon home miners, and a report about one is not a report about another. This is what is on record for each, as of 8 November 2026:
| Model | Blocks credited to it |
|---|---|
| Avalon Nano 3S | One: block 951,771, 31 May 2026, Braiins Solo. |
| Avalon Nano 3 | None that we could find. It is the older model: Canaan launched the Nano 3S in January 2025 as its upgrade. |
| Avalon Mini 3 | One: block 913,593, 7 September 2025, Solo CKPool, credited to a Mini 3 at about 37.2 TH/s by a retailer's timeline (DTV Electronics). Canaan rates the Mini 3 at 37.5 TH/s, about six Nano 3S. |
| Avalon Q | None in our Solo Block Record. |
Be careful with “6 TH/s” headlines too. In November 2025 Tom's Hardware reported a Solo CKPool block won with about 6 TH/s, from what it called an older-generation ASIC. DTV Electronics lists the same block, the 308th solo block through ckpool, as a likely group of five or six Bitaxe Gammas at 5.4 TH/s. Nobody named a Nano 3S, and a hashrate on its own does not identify a model.
Specs, power and live odds for each Avalon model are on the Avalon hardware page; every verified small-miner block is in the Solo Block Record.
The odds for one Nano 3S today
Canaan rates the Nano 3S at 6 TH/s. At the network difficulty of 148.36 T, in force since block 973,728 on 29 October 2026, here is what that gives you, next to the setup that won block 951,771:
| Setup | Chance in a day | Chance in a year | Average wait |
|---|---|---|---|
| One Nano 3S, 6 TH/s | about 1 in 1.2 million | about 1 in 3,400 | about 3,400 years |
| The winning address, about 147 TH/s as reported | about 1 in 50,000 | about 1 in 140 | about 140 years |
Run one Nano 3S for ten years and your chance of a block is about 0.3%. An average wait is not a countdown: each hash is a fresh draw, so a block can come in the first week or never. The odds are the same on every pool. The next difficulty change is due at block 975,744, around 13 November 2026, so use the live calculator at 6 TH/s for today's figures.
Mine for it on SoloLuck
To take the same shot here, set Pool 1 on your Nano 3S to stratum+tcp://stratum.sololuck.io:3333, the worker to your own Bitcoin address (a dot and a name after it, such as .nano3s, is optional) and the password to x. Port 3333 is the Lite tier, the one /setup lists for Avalon Nano miners, and a block found here pays its full reward to your address with a 0% fee. The app and web-panel steps are in solo mine with an Avalon Nano 3S.
FAQ
Has an Avalon Nano 3S ever found a Bitcoin block?
Yes, once on public record as of 8 November 2026: block 951,771, mined on Braiins Solo at 00:27 UTC on 31 May 2026. The pool's public statistics trace the winning share to a worker its owner named Nano3sC, running at about 6.7 TH/s. Many solo blocks never have their hardware published, so other Nano 3S finds may exist, but we found no other report of one.
Was it one Nano 3S on its own?
No. The winning share came from one Nano 3S, but its owner was reported to run 12 Nano 3S and 2 Avalon Mini 3 on the same address, about 147 TH/s in all (a Canaan distributor said 157 TH/s). Every machine on an address shares the same draw, so the setup had more than 20 times the chance of one Nano 3S.
Was the “6 TH/s ASIC” block of November 2025 a Nano 3S?
Nothing says so. Tom's Hardware described that Solo CKPool block's miner only as an older-generation ASIC of about 6 TH/s, and DTV Electronics lists the same block as a likely group of Bitaxe Gammas at 5.4 TH/s. A hashrate on its own does not identify a model.
Has an Avalon Nano 3, without the S, found a block?
Not that we could find as of 8 November 2026. Canaan launched the Nano 3S in January 2025 as an upgrade of the Nano 3, so a report about one is not a report about the other.
What are the odds for one Nano 3S today?
At the network difficulty of 148.36 T in force since 29 October 2026, one Nano 3S at 6 TH/s has about a 1 in 1.2 million chance per day and 1 in 3,400 per year: an average wait of about 3,400 years. The odds are the same on every pool, and the live card on this page follows the difficulty.
Has a Nano 3S found a block on SoloLuck?
No. SoloLuck has not found a Bitcoin block. If you mine here, use port 3333 with your own Bitcoin address as the username; a block found here pays its full reward to that address, with a 0% fee.
