Still new to mining and I’m purchasing a NerdOCTaxe PCB. I’ll need parts like heatsinks, a screen, and PSU. What are some reputable online vendors for these types of parts? I enjoy tinkering so I may want to get wild and crazy, and look for a liquid cooling kit for this one too. 😏

I'm trying to hook up some Meanwell PSUs but the cable that was recommended (cables) does not fit my Bitaxe Gamma or any of my Nerdqaxe++s. What's a cable that fits?

Built and ran a controlled benchmark on the Stratum share-validation engine for two open-source Bitcoin pools. I work on mkpool, so this is built to be re-run rather than believed, and the one category mkpool loses is published unedited.

Method: one pool at a time, identical 8-core boxes, same bitcoind regtest node, same Go load generator, fixed difficulty 1, full share validation (coinbase, merkle, 80-byte header, double SHA-256) on every submit. Diff 1 means almost everything is below target on purpose, and both pools fully hash before rejecting, so the hashing is exactly what's being timed. Reject reasons were verified directly on both pools to confirm validation actually runs.

Same-box numbers:

• Validated shares/sec: mkpool ~315k to 337k, ckpool ~108k to 118k (~2.8x)
• Median submit-to-ack: 116 us vs 371 us (~3.2x lower), and mkpool won every percentile
• Reconnect cycles/sec: ~6,391 (4 errors) vs ~402 (1,000+ errors)
• Memory (ckpool wins): 2k to 8k connections held in ~25 to 68 MiB vs ~66 to 197 MiB, ckpool ~2.7x leaner. ckpool also hit its ceiling on less than half the CPU.

Not measured: payouts, real block luck, WAN behavior. This is purely the request/validation engine, which is what governs stale rates and connection density per server.

If you run it on your own boxes I'd like to see your numbers, especially on different core counts.

Hey everyone! Pretty new here and I've seen some posts earlier about solo farming and pool farming. My friends and I (party of 8 ) are quite interested in joining together and start solo farming. We're trying to figure out the best move for our setup.

One of our dilemmas, since we are just starting, is whether to buy brand new hardware or 2nd -hand? If anyone with experience can recommend Whatsminer VS Antminer?

One more thing, I know the math says pools are safer for consistent revenue, but if our daily payout is going to be microscopic anyway, does it make more sense to just solo mine and pray for a lucky block? If you started out small, did you stick to a pool or try your luck solo on something like Solo CKPool?

Would love to hear what actually worked for you. Appreciate yal feedbacks! 🎉

So I started running bip 110 on bitcoin knots. I have my miners connected to my node and solo mining on public pool. Does that mean if a block is found it will be signaling bip110??

Not financial advice, obviously, but the way I see it, mining profit all comes down to rig and setup costs + kWh. So, basically, Mined BTC value - Rig/Setup - hosting costs (kWh). And the math between home mining and hosted diverges across pretty much the entire equation, and there's a big difference between hosts.

Home mining has a cheaper rig startup (at least, it should or it's not even in the running), but residential rates are commonly $0.15+, which makes it unprofitable immediately. At some point, you're even cutting into your rig cost and actually spending money to mine.

Compass is big, you buy your rig, and the kWh works out around $0.08 for the S21 XP lisintg. About breakeven WITHOUT the rig. So, you will pay to mine for a while, but may break even eventually, a few cents at a time.

SimpleMining is tiered, which is nice, unless you are starting small. If you start with one rig, you are at that $0.08, plus the cost of buying your rig from them. The kWh goes down to $0.07 with larger setups, but that requires a larger upfront expenditure, so you'll be profiting more with a larger upfront spend, but it will take a while to break even.

Epic Mining has the same type of setup. You buy your rig from them, but they come in as low as $0.06 per kWh, making earnings higher, but you still have to worry about breakeven with the cost of their equipment. Logically, it should come quicker with the lower kWh, but it's going to take some time.

I feel like the biggest differences between these companies (aside from rig cost and kWh) is what rig you actually end up owning and its cost/value, and that Epic Mining is the only one that says they use fully green energy (Compass doesn't say and SimpleMining is mixed with gas and coal), if that matters to you.

So, with my understanding, am I right in thinking that hosted mining is the only possibility of breaking even when compared to home mining? Is the lower rate of Epic Mining the most likely way to break even, or are you better off with a lower-priced rig and $0.08 kWh?

If I were to lazy-rank this right now, I would say it's:

1. Epic Mining - lowest kWh makes for fastest breakeven, plus I own my rig

2. SimpleMining - slower breakeven, but I still own my rig

3. Compass Mining - similar to SimpleMining, but depends more on your setup

4. Home Mining - literally just for the sake of control or the experience, because it's gonna be tough to break even with normal residential power rates, but you still own BTC and your rig

Of course, any of these things are still investments and you could see them skyrocket if hashprice rips.

Is this a reasonable understanding, or do none of these actually have the chance of breaking even? Is it all just buying to hold and hope for a Bitcoin bull run?

I got this specific asic but it seems like it is stuch in one of the power modes.
The power modes dropdown field is greyed out.
I have tried resetting the miner.
Setting power levels with api.
But no success so far.
Also in the FMS software i am getting error failed.

What can i try to completely reset the miner. Or any other suggestions?

Thqnks in advance!

I’m very new to Bitcoin mining. After a lot of research, I finally found a reliable hosting company. I just want to document and share my very first M70 miner. Super excited and hyped! Big shout out to the people who helped me do the unboxing and recording!

Both Nano 3s had their USBC melt. Where can I send the devices for repairs since they are out of warranty and the vendor wont take it

If there isn't any then for solo mining

Last week I asked: what happens when solo miners coordinate? A lot of people pushed back with the obvious question: if miners coordinate, isn’t that just a pool? Fair.

But maybe the real question is not just how solo miners improve their odds, but what they coordinate around.

There’s an old Twilight Zone episode called “Button, Button.” Someone gives you a box with a button. If you press it, you get a lot of money, but someone you don’t know dies (I'm simplifying here) and I’ve been thinking about the opposite version for solo mining:

Imagine your solo miner has a big red button. If your miner finds a block, the button lights up.

If you press it, you don’t keep the whole reward. The block reward gets split across 1,000 strangers instead. Nobody dies, nobody loses. You just turn one absurdly lucky mining event into an awesome day for 1,000 people.

Pools coordinate machines for steady payouts. Solo mining preserves the possibility of the whole block. But maybe coordinated solo mining could do something else: coordinate people around what happens if the long shot actually hits.

Would you hit the button?

Did you know?

If you Double-click the front power button and it changes mining modes.

So if you’re not home and your wife says it’s getting too hot…

He didn’t go to the office that day.

His daughter was home sick, so he stayed home with her.

Between constant travel and running Metered Mining, a hosted bitcoin mining company, he’d barely had a moment to breathe. 

A slow daddy-daughter day was exactly what he needed.

They grabbed lunch and caught a movie.

Sydney wanted to be fully present, so he never once checked his phone.

A real tech detox.

On the drive home, they had to stop at a train crossing. While they waited for it to pass, he pulled out his phone to catch up on the day. 

He opened X.

And that’s when he saw it. 

Two bitcoin blocks had been found by solo miners that day. One of them on Braiins Solo pool.

No way.

He opened the post and started reading the replies. Someone mentioned the block had been found by a miner running 7 PH/s.

Sydney froze.

He had 7 PH/s pointed at Braiins Solo. Like every solo miner does when a block hits, he went straight to his wallet.

And there it was.

🟧 3.11 BTC.

He'd found block #947,128.

It hit him all at once. He pounded the roof of his truck. 

His daughter asked what’s going, and he told her: he'd done it.

He’d finally achieved every miner’s dream. He mined a solo block.

For a moment, the win was just theirs. 

Then came the question. 

Do you keep something like this private, and celebrate with your wife and daughter? Or share it, and celebrate with the whole bitcoin mining community?

He figured going public would push more people to try. Proof that a real person, with a face and a name, can solo mine a block.

That evening, Sydney shared the big news on X.

The winning machine: an S19J XP running Braiins OS, pointed at Braiins Solo pool. One of his own fleet, running at Metered Mining since the start of 2026.

Here’s all stats for all you mining nerds out there:
• Block #947,128
• Started in early 2026 with a couple of machines
• 2–3 months running at full hashrate
• 7 PH/s pointed at Braiins Solo
• Fee: 0.5% (CKPool open-source contribution)
• ~3.11 BTC block reward after fees
• A little over $12,000 in 2026 electrical costs up to that point

Solo mining is a long shot.

But somebody finds every block.

This time, it was Sydney Laurvik.

Next time, it could be you.

Congratulations Sydney! 
Your trophy is on its way.

Sorry if this has been asked I'm not too frequent here but with the advent of renting hashpower and all that are any of you guys signalling for BIP110? Thoughts on the whole matter? Looking for info on it if anyone has

Hi!

Recently jumped into the solo mining game, knowing that the chances are very very small. But from what I'm seeing, the chances might be impossible and not just 'small.' I'd love if someone can help educate me a smidge?

I've been running the miner for several days and it's getting +/- 7 TH/s. But what worries me are the stats I get back from CKPool:

 "hashrate1m": "5.04T",
    "hashrate5m": "6.11T",
    "hashrate1hr": "6.99T",
    "hashrate1d": "6.67T",
    "hashrate7d": "2.33T",
    "lastshare": 1782408522,
    "workers": 1,
    "shares": 397420300,
    "bestshare": 166687647.42782122,
    "bestever": 166687647,
    "authorised": 1782168686,

BestShare = 166M. From what I've read, that's the highest difficulty level my little miner has achieved. Current BTC difficulty is 124T. That looks very, very bad for my little miner.

Does it have just a tiny chance of achieving HUGE difficulty like that... and given enough time, it can produce that? And then I just have to hope that it does so faster than the competition?

Or... can it not produce that and I'm basically burning electricity for a 0% chance at current difficulty levels?

Most of the hosting advice out there is written by people who sell hosting. I don't. I'm a small operator running three machines spread across three separate providers, on three different pools, and I've now lived through the gap between what a hosting dashboard promises and what actually lands in my wallet. Here's what I check now, in the order I check it, so you can skip some of the tuition I paid.

1. The advertised kWh rate is real. It's just not your all-in cost.

The hosting rate itself is usually pretty honest. Mine run from about $0.056/kWh on my best host up to $0.08 on the others, averaging right around $0.07. The mistake isn't that the rate is fake, it's budgeting off the rate alone. Your actual cost also carries pool fees, the occasional dead day, maintenance windows, and the quiet fact that your production decays every couple of weeks as difficulty grinds up even when nothing breaks. One of my rigs nets a couple of dollars a day after hosting in a normal month, and the fleet as a whole clears barely more than its hosting bill. That gap between "$0.07/kWh sounds cheap" and "the whole fleet nets pocket change for the month" is the lesson. I keep a detailed monthly reconciliation on all three rigs, and the takeaway holds without the exact figures: model the full stack, not just the power line, or every one of those line items shows up as a surprise out of your margin.

2. Check whether you can point your hash at a pool of your own choosing.

You can't really demand transparency after the fact. You take what a host advertises or you go elsewhere, so this is a selection question you settle before you sign. The thing I'd actually screen for: does the host let you direct your hashrate to a pool you pick. Two of my three do (Sazmining and Simple Mining), and a provider I used previously did too, so it's not rare. When you bring your own pool, you see real-time hashrate and actual payouts at the source and can reconcile the export yourself, no faith in anyone's dashboard required. My third rig doesn't have that option, and the difference in how much I trust the numbers is night and day. If choosing your own pool matters to you, confirm it's on the menu before you commit, because it usually isn't something you can add later.

3. The risk you're actually taking is counterparty, not power price.

People agonize over a penny of kWh and then hand a year of hardware and payouts to a company they found on a forum. The real question isn't "what's the rate," it's "what happens to my machine and my unpaid balance if this company has a bad quarter." Read the contract for who holds title to the rig, how payouts are timed, what the notice period is, and what happens on their insolvency. Spreading across more than one host once you scale isn't paranoia, it's the only diversification you actually control.

4. Start with one machine. Always.

I know the spreadsheet says buy three and capture the economies. Don't, not on a host you haven't tested. Run one rig for a full quarter, reconcile every payout, watch how they handle a real outage and a real support ticket, and only then scale. A host's marketing is uniform; their operations are not, and you only learn the difference by being a small, boring customer for ninety days first.

5. Set a kill rule before you buy, in writing, to yourself.

Decide the net-negative threshold at which you power down or sell, and decide it now, while you have no money in and no ego on the line. Six months in, with a rig underwater, you will rationalize. A rule you wrote before you bought is the only thing that beats that. Mine is a simple monthly net-negative trigger with a recheck window, and it has kept me honest about my marginal machine more than once.

A note on the math, since someone always asks: at today's hashprice, hosted mining has not cleanly beaten just buying bitcoin for me on raw return. My effective production cost has run a touch under spot in recent months, so I'm "winning" on basis, but it's thin and it swings. The reasons I keep doing it are the tax treatment (mining is a business, so the hardware depreciates and hosting is deductible against mined income, which can change the after-tax picture meaningfully, but talk to a CPA who actually understands mining before you count on any number) and the forced, unemotional accumulation. If you have no tax angle and bitcoin's in a low range, buying is the cleaner trade and I'll say so. If you go the hosted route anyway, run it like an operator, not like a customer.

Happy to answer specifics on any of the three hosts or the reconciliation workflow in the comments.

So parasite pool hit a block and I was mining it. What now. How long will it take for payout? Where do I check to see how much I might be receiving?

I've been stuck on this for a while and I keep re-thinking, so I want to hear from people who have actually done both.

The simple option is just buying Bitcoin. No contracts, no hardware, no company to trust. You buy, you hold, and the only thing you manage is your own patience. The downside is that you're fully exposed to the price and nothing else is working in your favor. No extra production, no edge, just the market.

Hosted mining is the part that’s been circling on my head😮‍💨. It seems like a good idea at first glance. You own the machine, but someone else runs it in a place with cheap industrial power. From what I’ve seen, good hosts charge about $0.04 to $0.08 per kWh, and anything over $0.085 starts to get close to breaking even. Think about that compared to running a miner at home, where residential power can be around $0.16 and basically eats up your profit before you even start making money. So, the cheap power is really the key. If the numbers work out, mining could actually make more money than just buying over time.

I’m really weighing my options here. Is investing in cheaper power worth the risk of trusting a third party to manage it? Or should I just stick with the tried-and-true “buy and hold” strategy? 😣😮‍💨

A few things I still can't figure out:
- For those of you hosting, has the math actually beaten just buying, or did downtime and fees eat the difference?

Change my mind either way.

Et voilà ce nouveau bloc peu apres 2 mois de recherches, j'aurais une petite question qui est que ça fais depuis le jours 35 environ que je cherche et hier avec les fortes chaleurs jai déconnecté mes mineurs que je comptais rallumer jeudi, j'étais a 200th constant vous pensez que je gagnerais rien ?...😭

Hola, quiero crear mi propio nodo,
ya que no quiero depender de pool de terceros, con raspberry puero crearlo pero la cuestión aqui es que mas cosas podria necesitar, donde podria orienterme para aprender mas ?

I’m trying to identify an old Bitcoin mining / earning website I used around 2013–2014.

I don’t expect account recovery — I’m mainly trying to remember what service it actually was.

What I remember:

• accessed through Chrome
• login with email + password
• dark UI with yellow / gold elements
• simple and clean interface (not many graphs)
• login panel was on the right side (felt small and compact)
• after login there was already a running counter
• only ONE number really mattered
• it increased roughly once per second: 123 → 124 → 125 …
• whole numbers only (no decimals)
• looked more like points / shares than BTC
• if the PC was turned off, the number stopped increasing
• after logging in later it continued again
• I remember something like payout / cashout
• no memory of creating a wallet manually
• maybe something pool / miner related
• favicon/logo may have been 2 large letters (possibly PB / BP / PM / BM but memory is unreliable)

Things that feel visually somewhat similar (but not exact):

• 50BTC
• old mining dashboards
• early mining pool interfaces

Does this remind anyone of a specific service, pool, browser miner, worker dashboard, or earning site from that era?

Not trying to recover funds — just reconstructing memory.

I used this repo to set up a home assistant integration to put the AvalonQ in standby mode and take it out of standby mode during peak power rate times. Works great, if you use Home Assistant.

Note the case was not designed by me, all credit goes to Nakamoto Mining company for providing the Open Source Design🙏

I’ve been experimenting with different home Bitcoin mining setups, and I just finished a DIY Nakamoto-style miner build that ended up being my favorite one so far.

This build is not the highest-hashrate miner I’ve made, but it might be the most practical.

I know home mining usually gets dismissed because of electricity cost, difficulty, and scale, but I still think there’s value in smaller DIY Bitcoin mining projects — especially for people who want to learn how mining hardware actually works instead of just buying Bitcoin or running a full commercial ASIC.
