FWIW this bug only affected the best difficulty being stored to the non-volatile memory. Nothing to do with shares
The display didn't match up with the pool data on best share which is what I was referring to. If you only look at the display for best share or the UI then you really wouldn't have accurate best share info. I am glad to see this fixed! we could use your good luck to test this fix out! |

And all of us are lucky that Avalon / Canaan is shipping slowly if they were fast it would kill off all of the units above.
That’s a good point! You have to wonder why they are half-assing the sales. Is production just not ready yet? Is this a temporary, loss-leader product? Maybe a limited supply of chips? I guess we’ll find out. Margins have got to be razor thin with 10 chips in there. I can assure you that none of the projects you listed are getting “killed off”. More like “super motivated” now. |

Only selling the Avalon Nano 3 on a crowdfunding website is bullshit. I’m still waiting for my “February Delivery” unit to ship btw.
Full Disclosure: I’m the Bitaxe project instigator.

I bet some companies are looking into it, you might see one used in coming next generation ASICs
No you wont. Mining is simply: generate a header, then run the nonce from 0 to 2^32-1 Changing that nonce order will have no effect at all on luck - zero - none - absolutely no reason to do it. You also cannot selectively choose nonces that will give better results - since you have to hash the nonce to find out - which is what a miner does. Anything more complicated than simply incrementing the nonce would slow down mining, and decrease efficiency. Each chip is changing the nonce around 500 billion times a second. There is no time to mess around -- especially when, as Kano says, there is no benefit. (Modern ASICs also roll bits in other fields, but same idea) |

I've got two Bitaxe 201 boards. One of them is happily hashing away after applying esp-miner-factory-205-v2.1.3.bin directly to it over USB. I was unable to connect via USB to the other one, so I updated the firmware to 2.1.3 (successfully) via the web interface. However, when I tried to update www.bin, it hung for about 10 minutes. After power cycling it, there's no display and I still cannot see it via USB. Any ideas on how to get this working again? Thanks! It's not a good idea to apply the v205 factory firmware to a v201. I'm glad to hear it's still working though! As for your other unit; Did USB ever work? Make sure you are powering the Bitaxe with the 5V main power and not just USB. If that doesn't work it sounds like faulty hardware. |

It’s unlikely that’s the sustained hashrate. In fact, D-Central the company that made this unit says the following; Beautiful shot! Give it time, it will normalize the hashrate haha, but some of them can maintain 800GH/s. Very impressed with the BM1368 chips so far.

Also be aware that the metal top of the BM1397 chip in the S17 series is somewhat electrically connected to the chip VSS.. And VSS is not the same voltage across domains.

Is there a ethernet slot?
Can i use it via wired mode? What about typc C slot?
No, the Bitaxe is wifi-only without significant modifications to the hardware and firmware. |

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/bitcraneThe 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. |

I think a 600-900 watt 120volt miner 20-28 watt per th miner would have more traction for buyers then a 1 or 2 chip miner.
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. |

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. |

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..

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.
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. 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.
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. 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. Nonetheless, you doing a great work.
Thanks! It’s not all me. There is a solid crew at OSMU working very hard to bring open source back to Bitcoin mining. |

It is now possible to run your own mining pool on Umbrel with the software from Public pool. That's really fun to be able to do. If someone ever finds a block this way, how can we make sure it doesn't become an orphan block? How can we ensure that the luck of ever finding a block isn't spoiled by an orphan block.
We should have Public pool broadcast its block fast to important distribution points. These would then quickly broadcast the block across the network. The Bitcoin node is, of course, also connected to its own peers, but we don't know if they are fast enough.
My question is what can we do to ensure that the chance of an orphan block is as small as possible.
Make sure your home internet is reliable. Finding a golden nonce and having your internet get all Comcast on you is going to kill your chances no matter what solo pool you mine with. Shaving a few 10s of ms off your latency by using Ethernet isn’t worth it for a small operation |

Just wondering how would I go about hosting my own solo mining pool? Is there any tutorials?
Thanks in advance to anyone that can offer some more information on the subject!
Get an old PC, put a 2TB SSD in it, and maybe some RAM. Look for some tutorials on installing Umbrel. Once you have Umbrel up and running, and the initial blockchain download has finished, install Public-pool from the Umbrel App Store. It’s pretty chill! You can point whatever miners you want at it. |

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.

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
