Bullshit.
Your statement would only be valid if China had a national grid system like North America (excluding Texas) and most of the EU have. A national grid lets a country generate power in one area for use in another, if one area has too much generating capacity power can be sent to regions where there is not enough generating capacity.

China does not have a national grid so during the rainy seasons the hydroelectric dams are now running far below capacity because there are no miners to take up the excess power. With no grid system that potential power production is now wasted and water is just being dumped downstream vs going through a dam's turbines/generators. That is why officials in Sichuan tried to get the CCP to allow mining to continue until the rainy season is over.

Yes it does. The question is a non-existent case that will never occur.

The pool will NOT send the same work... If it does then there is something seriously wrong with their software...

It is not a hardware ID. It is an ID generated by the pool when a miner connects to it.

As far as I know, Slush begat the Braiins team to develop Stratum V2 and BoS to work with it. The Braiins group recently bought/rebranded the original Slush company.

The key point folks here are getting to is that running a miner much less several requires setting up significant power circuits and is not something most folks can, much less should attempt, to do by themselves. It requires working with a licensed electrician to safely spec and install the needed circuit breakers, wiring, and sockets.

Odds are Kano will be piping in eventually but suing Bitmain in China back then was a non-starter. He did do some work for them regarding the S1 but shelved it after BM refused to address the terrible performance of their FPGA driver. Beyond that, for a time both he and -ck did bug BM enough that as they released new miners Bitmain eventually (several months after release) *would* publish their source code for miners up to the early S9's.

I might add that Kano does have better performing versions of firmware for the S1 & S3's on his dl site. Also of course has the full source code for them there as well.

Yes, Braiins is 'Kano Approved' as an original work. Don't know how much is just a re-write of cgminer using a different language (Rust) and how much is new 'clean' code but the key point is that Braiins published the source code.

Well, he is doing all that he can. He and -ck are not about to give cgminer to the FSF who are the only ones with the resources to go after violators. All he can do is 'shame' them. In the past already has made mention in their respective support threads of Bitmain, Inno, MicroBt and others violating the license but that is beating a dead horse especially since the other major (and Primary) developer (-ck) could care less. Canaan has been the one exception in that they DO (or least, did) publish their modified source code. That leaves nagging programmers who should know better and support the ideals of what Open Source is supposed to stand for.

How would they feel if someone decompiled or just repackaged  their code after adding a few tweaks to it and then proceeded to make money off of it? Pretty safe bet that said programmers would be highly miffed...

Mining software?
ASIC-based Bitcoin miners are stand-alone devices that do not use 'mining software', they are not crapcoin miners based on using a PC and GPU's. The only software (such as AwesomeMiner) used is for monitoring. All you do is open the miner web GUI, enter pool & user information, save/apply and run them.

100% verifiable code yes. It's already available. Hardware is another story because there are VERY few Foundries in the world that are capable of making decent speed CPU's and at least one of them will be making the actual chips (and support chips).

That means the Foundries must be trusted to not fiddle with the chip designs and put in backdoors at the request of governments. So far, that is NOT an issue with Intel (edit: being a separate stand-alone bit of logic on the same dies as the CPU, ME *can/is* one but can also be disabled), TSMC, Samsung and Global. btw: that is the whole point about the US and EU blocking/restricting Huawei and other China-owned makers of network and other communications gear being sold/used in their jurisdictions - the chips and gear are pretty much wholly produced in China so major concerns about backdoors there.

edit: found that Intel's ME *can* be disabled. More explicit description courtesy of bleeping computer is here.

Since you are so against Intel's ME, just use a PC based on the ARM or AMD or other non-Intel CPU's... Problem sort of solved.

Only catch is that the CPU's require compilers to translate the OS code into the CPU-specific microcode which is doing the actual data manipulations in a CPU. Those compilers are based on code libraries that come from the CPU makers. So... in many ways there is still proprietary closed-source code being ran.

That said, yes there *are* "Open Source" CPU architectures out there. A quick article about is here. Also just do a search for "open source CPU" to find a lot more about it.

Only 1 problem with that -- considering that miners get paid for processing blocks, changing the algo to make it 'CPU friendly' would mean that gazillions more miners would be cheaply brought online and difficulty would still skyrocket as a way to keep to the existing rewards schedule. If the algo is changed to keep diff low the network could easily be swamped with miners vying to get the finder reward or more likely and worse yet, bad actors easily DOSing the pools/nodes or applying 51% attacks..

The existing POW format prevents all of that by making it exceeding difficult & expensive to attack the network..

Have you contacted the distributor or Canaan?
What is the line voltage feeding the miner? It must be between 208 -240VAC.
The Avalons are very easy to work on and odds are that if a replacement part is needed it will be sent for you to replace vs sending the miner in for warranty repair.

The main things to keep in mind is that:
a) for all intents and purposes the spaces between the sound baffles are air ducts and air flow through them must be calculated. Those 90-deg bends will introduce considerable resistance to the airflow so include that.

b) remember that you are calculating the airflow rate as in CFM or M³/min. The air velocity should be kept very low as velocity is what drastically increases airflow resistance through ducts and around corners.

There should be scads of calculators found online. Just search for "calculating HVAC duct airflow"

The explanation is not weird: If one is running a pool then one must allow the OEM firmware because that is what the vast majority of miners use. It is tilting at windmills to do otherwise. Sure it bugs the hell out of him but it is what it is. A few years back even -ck bitched about Bitmain using cgminer but later backed off after a certain someone reminded him that he (-ck) led Bitmain down that path by refusing to do any work for the s1 even after BM sent him a miner to test on.

Now regarding,
"Them" of course is referring to miners using 3rd party firmware and yes he DOES prevent its usage on KanoPool. Part of the data exchanged between a miner and pool identifies what the firmware is and his pool software automatically disconnects any miner that is not running OEM firmware. The only exception is BoS because the sourcecode is published and that only works on the Solo pool until it is proven that BoS finds blocks. Once someone finds a BTC block with BoS and can prove it (preferably by mining it on the Solo pool) then BoS will also be allowed on the main pool.

The graphic shows an exhaust fan that pulls in cool air while exhausting the hot air. Just no true indication of the size which of course all depends on the heat load.

Probably an exchange moving BTC between different internal accounts eg, cold storage to hot wallet or visa-versa?
Or, someone cashed out a very nice long-held stash for their retirement =

Yes it does but -- in confined space forced air systems the layout shown is correct. What they are doing by feeding the cooler air upwards at one end of the enclosure is sweeping the hot air from above and forcing it downwards at the end to give a more or less circular airflow inside the enclosure to avoid creating dead spots. They are also relying on the motor fan to provide horizontal airflow towards the inlet side of the box where it hits the wall and moves up to mix with the cooler inlet airflow.

Note that the design is only for small(ish) enclosed layouts - not large layouts with aisles of server/miner racks. Once you dealing with rooms full of gear the airflow's are radically different.

Most folks here will tell you that getting a loan to purchase miners is a very bad idea because it is exceeding risky. Nothing about mining is certain and there is always a good chance that things will not go as you planned. If things go wrong the last thing you will want is a loan hanging over your head.

Now, if you already have some miners and they are providing stable income - and assuming your bank is good with using that income as an asset - you could use that record of income to aid in getting a business loan for other things but I would still be wary about it.

And my point is that using your favorite search engine to look for say "bitcoin mining pools" will turn up a lot more information about what pools are out there. Plus, you will have to decide between a PPLNS pool that pays when they find a block or a PPS pool that pays at a constant rate that depends on what you hash rate is. All have pluses and minuses and wildly varying fees that you have to look at and because everyone has different priorities, decide which they like.
