Hey cygan, thanks for the shout out! It's true the new Bitaxe is called the bitaxeSupra and it features the BM1368, the ASIC from the S21.

As some people have mentioned, it's hard to get the chips right now, because it's so new. I'm sure that will change soon enough. This is exactly how things went for the BM1366 from the S19XP.

The bitaxeHex development continues with the BM1366 for now, because of chip availability and the fact that some work still remains on the BM1368 protocol.

As always, check out the OSMU Discord for more! Invite link at bitaxe.org

Is that a politically biased opinion or there exists a valid technical reason behind it? Cheesy

Lol, the hundreds of thousands of Russian coming to Europe with the same stories of corruption and government taking their chunk of business, with agencies demanding they would hire people that would no nothing just stay there and monitor how much you have to pay, with the whole weaponizing of every trade, with the takeovers of business on a wimp, you think this is political bias? 
My company traded with russian companies before, you know how funny is to give full paid vacations to people that don't work for you?  Grin Grin

But regardless of what you think about said country, I doubt you think they are worse than China, do you? the Chinese had control over bitcoin mining, and nothing happened, personally, I don't believe "evil" would exist in the mining business regardless of the government views of BTC,

Well nothing happened at all for years, and suddenly they wanted miners out! Could anyone have done something against it? No!
The fact that something worse didn't happen doesn't mean it won't , it simply means they didn't felt like doing it!

I highly believe that rich people are stronger than all governments, if there exists a country where a few rich people own 20-30% of the total hashrate, it means they are strong enough for any government to screw them over, I know what some legacy media might tell you about countries that are ruled by a single man -- they say the same thing about my country, but I know such things don't exists, power resides where money resides, the government (or otherwise a single handed man) is only strong enough to control the average citizens, the rich -- will always operate as they please and will always do what's best for their investment.

Jack Ma probably would have a story to tell about that! So would the dozens of Russians businessmen that jumped from a window, or the Lukoil chiefs that decided to kill themselves with their families the same day in different countries on vacation!  I don't know exactly what county you talk about but there are levels of corruption and distribution of power, your country could jail people for 25 years for insulting the head of state and still not be as rotten as those.  It was the same here under the previous CP, eveything was fine till it wasn't and declared a threat and my relatives ended up for years in jail because of suspicious "roots"! They too might have a story to tell you but unfortunately I can't arrange even a spiritual session, cause even now we don't know where they got buried! If...
It's the same thing that happens to some in quite freely run states, one tiny abuse and they think they are as worse as NK, but they've never actually experienced even 1% of what's there! Trust me, you've never actually experienced true dictatorship, or at least you haven't been on the wrong side at the wrong time!

Back to the miner, don't get me depressed on Saturday night!

Ya but that is a lot of "ifs" which we all know isn't going to happen, there are not enough people (millions) who can afford and care about "mining decentralization" without caring about the cost/profit, also given that we talking $100-200 per th, it just not going to happen, even if you had millions, speaking of the device in the this very topic, it does 0.7th per device?

Wait, let's not go for zeus price but for prepackaged chips!
So not $40 but 5000/324 so that would be $15.
Again, I don't know shit about the rest and the prices for it , Skot was still active lately here so he might throw around a number and I think we could drop the above quota to 4 or 5 if we talk massive manufacturing and not 100 orders!

so you are going to need 1.4M of them to obtain 1EH which is not even 0.2% of the total hashrate, so what are the numbers we talking about? we want these small miners to gain 25% of the network hashrate? great then we need 210,000,000 of them.

1) I was aiming at things a bit higher, that would be 40-50W so 4-5 times higher and shaving 20% at least after the halving.
2) How long would the reward be able to keep that massive hashrate online? The price won't double forever, at some point all the extra things (land,rent,wages) will take their toll
I won't say it's doable now or even remotely in the next few years but I would rule out the word impossible!

in BTC, it's different, if you are not finding blocks -- you are just burning electcity for no good reason.

I don't understand why you're fixed on solo mining and why those couldn't be part of a p2pool?
But ok, let's drop the torrent and switch to fold@home example!

I believe the opposite will be true, the more times goes buy, the less eleciticty BTC would use, of course, we are not there yet, but I think of it as climbing a mountain, we would get to the top of it and then start going down, the only reason why the market still allowes electcity growth is because we have not hit the effiecny wall and the rewards are still huge, eventually, when there is a little room left for hardware improvement, and the block rewards are next to nothing, there bitcoin ecosystem won't have a room large for everyone.

Which brings us to point 2 in my above reply!  Grin
I think that after another halving the ratio of what % of the hashrate you can buy for $100 will change dramatically, of course counting inflation.

But as much as I know thousands could use this in the USA I doubt I will be able to more than a few hundred of them.

The moment a heater cost $50 at walmart and the miner heater cost $500 and recoups only $10 a month probably not even 1% would.
30th is 2-3 a day or 60-90 a month.

if you need a space heater and run it six months a year you get back 360 to 540 a year.

if you do not need a space heater you do not need the modded miner.

1 million bitaxe is over a 0.5 EH/s. If they’re solo mining (to a decentralized node, as they should be) then a Bitaxe will solve a block every 7 days, on average. We’ll get there, I have no doubts. Home mining unlocks _a lot_ of potential miners that would never touch a 3kW Antminer.

So it is within your vision that these miners would only be used for solo mining? Not that it affects their chances of hitting a block but is it how you imagine them to be treated?

You can see in this very thread that my view on them is the same, they are too small for regular PPLNS or PPS, but good for the individuals who want to take a gamble on hitting a full block.

My questions however, (which have been addressed here but you may have not read them) is the cost of these miners if done at large scale, or at least the consumer price.

Also, have these miners found any blocks yet? Doing so on the testnet isn't quite all convincing to some people,and that includes one of the solo pools operators in this forum.

Nonetheless, you doing a great work.

People obviously can use them however they want. I do think solo mining makes the most sense though. Pooled mining guarantees you will only ever get a small payout.

As with all electronics, the cost comes down substantially in volume. This includes the ASICs.  When we start manufacturing in the 10s or 100s of thousands you’ll see the retail price come down a lot.

Quote
Also, have these miners found any blocks yet? Doing so on the testnet isn't quite all convincing to some people, and that includes one of the solo pools operators in this forum.

Not that I’m aware. That said, nobody knows how many bitaxe have been made, much less if one has solved a block or not. That’s the beauty of decentralization.

My rough rough guess how many bitaxe built is around 3000. Even if they were all solo mining, statistically it’s not surprising a bitaxe hasn’t solved a block yet.

I think these for-profit solo pool operators are incentivized to spread FUD about competitors. Fine, whatever — all the source is out there for you to verify.

Thanks! It’s not all me. There is a solid crew at OSMU working very hard to bring open source back to Bitcoin mining.

hmm, the person in question wrote a truckload of code for the community including Cgminer, you probably use/used some of his work before, he is not spreading fud, and he has a valid reason to deny firmware/hardware that was not proven to solve blocks, as that would have a negative effect on the other PPLNS pool participants, obviously, he seem to be the only person doing so because almost every other pool I tried had no issue with anything that found shares that meet the pool difficulty.

But ya, hopefully, soon somebody will post some screenshots of a block they found using one of these little toys, good luck Skot.

I dunno, claiming that the bitaxe or public-pool can't solve blocks on mainnet (even though they have on testnet) sounds like FUD to me. Maybe you can point me to that discussion? Happy to talk about specific concerns if there are any..

I don't get the solo mining thing.

If you think of millions of device you smut simply cut out the hobbyist scenario, there won't be that many eager to run this thing and a node and always look after their configuration and so on. If you want to make it mass produced to put a dent in the hashrate and the large farms share you need people that plug the stuff and press on, and they check on their app how many nanocents they have made per day.
I believe in a future potential for those, probably after the mining business is no longer receiving funds like a novelty and investors start questioning the billions they threw at, so bye bye running on credit, but in a future with those device dominating and solo finding blocks and propagating them, no, this one I is a too much of a far fetched scenario right now.

If you want to pool mine and get nanocents a day, that's totally your option. If you want to solo lottery mine with odds (and prizes) better than state lotteries 24/7, that's also an option. Either way, open source home miners will be quiet, cool, affordable and anonymous. The future is coming right up.

You should check out the people making miners with single Antminer hashboards. They're called "Loki Rigs" and are right about at the specs you mention.

yeah I have a source altairtech.com

I purchased this case.

https://altairtech.io/product/bitchimney/


but I have a different way to build it with much less parts.

I think I will use an xp board and try to keep it under 40th using 840 watts.

If the build works I will do some sales of the build.

I am waiting on parts.

I want to run it with 4 nuctua fans.

my version will be 900 watt max not 1200 max like the Loki as it is cheaper to make my way.

Altair is awesome. I've got a bitchimney running here with a S19k Pro hashboard and it's been great.

I built an antminer control board replacement called the Bitcrane that a couple people have been using with Loki rigs; https://github.com/skot/bitcrane
The Bitcrane requires a separate computer like a raspberry pi to run the firmware. The fix for that is a version with a raspberry pi compute module on board called the Bitcart; https://github.com/skot/bitcart but that is less far along.

The coolest thing about these control boards, IMO is you can use WiFi and whatever fans you feel like.

Interesting and waiting for the Hex

Meanwhile we shot with a lot of small miner to the solo pool her

https://bitcointalk.org/index.php?topic=5478927.0

Please have a look if you have also a small miner and try it in a group, to find a block or compare your bestshare in our solo mining race… post nice photos from the home Mining Equipment

Best regards,
Willi

No, the Bitaxe is wifi-only without significant modifications to the hardware and firmware.
