Exchanges and mining pools are not the blockchain itself, anyone can ban anyone from using thier services, in fact, Marathon (a large U.S miner) has been censoring transactions from U.S sanctioned addresses for a long time.

Of course they are free to do so, the protocol allows them, what worries me more is if every U.S based node bans those addresses, that will be an on-chain censorship which could potentially cripple crypto use case.

@Phill, no Putin is not under any induced stroke, he took Crimea long before covid started, he is fully aware.

So you think he needs to be removed from office? I hope you had the same thoughts about every U.S leader who bombed or invaded another country and killed millions of innocent souls.

It is funny that many of my westren friends think it is ok for NATO and the U.S to invade other countries and drop thier "democratic" bombs on innocent souls, but Putin can not do it because his bombs are not so democratic or/and the vicitms are white people.

Russia has been bombing Syria for years, killing civilians everyday, I do not recall anyone called for Russia ban, I am most certainly against this invasion and all sort of wars, unlike many I witnessed war and lost many dear souls, but It is either we as crypto miners stand against all wars or shut our eyes on all of them, cherry picking what type of victims you want to be sad about is far from logical.

Using VPN could be somehow a safer option, but that does not increase anonymity by much, he says he wants to donate to a "country", anyone who follows the news knows that it's Ukraine, and the fact that he wants to keep anonymity at high level suggests that he probably from Russia!! and if he is caught doing so, the consequences can be deadly, I surely won't trust a VPN with my life for that matter.

It's not easy to track you, but you are not 100% safe, and here is why, once you establish a connection with the pool, your ISP might perform an Eavesdrop attack on you, the worker/account name will be in those packets which you exchange with the pool, it's not like the Stratum protocol will send all these info in plain text, but there is no guarantee that nobody can see what's happening.

These kinds of attacks are not so easy to perform, and chances are, they will usually be targeted to actually work, but I don't know how much effort and money your ISP is spending to look at things like that.

I think it's a lot safer if you just mine to your own address or use a new address which you own, withdraw the coins to a solid mixer, use the mixed tokens to directly donate to that "country that is in need of help".

Not sure I would call that "nice", there is no reason to hold the Russian citizens responsible for an action that was taken by a single man, it's not like Putin cares about the suffering of his own people, so by doing so, you are only making life harder for people who are already suffering, the folks in charge will not be affected by all of that.



All the mining gears manufacturers are owned by the Chinese, China is siding Russia,  it is extremely unlikely that they would do anything that could remotely piss the Chinese government off (of course, this assumes the unlikely fact that Bitmain and the likes of it are willing to lose a single client of theirs in the first place).

It might make more sense to boycott Chinese products "including mining gears" and somehow put pressure on China rather than doing the opposite, but again, will any of us or the large U.S players stop mining to a Chines pool or stop buying Chinese products for the sake of Ukraine?

I believe the best thing miners can do is use crypto to donate to whichever side they support (I hope we all agree that not all of us are against this invasion in the first place).

Lastly, may God protect the innocent people of Ukraine and every other nation.

Asic.to is a distributor for Vnish, just like AwesomeMiner, they all are legit and they all use the same firmware, you just get extra added benefits using them like more support from Asic.to or a great monitoring tool for AwesomeMiner.




The mod does not really solve the issue by any means, in most cases the issue is below the chip and not above it (bad pcb to chip solder, not chip to heatsink solder), however, using one block of heatsink on top of the chips makes "fixing" those miners a lot easier since it's pretty hard to troubleshoot the miner with all those heatsinks on, I see some people take out a dozen heatsinks just to find that one bad chip, so without a doubt, unscrewing 4 or 6 screws to get a perfect vision on all the chips is a smart idea nonetheless.

202MW is about 150,000 S9s, I know most folks there use S9s so it's safe to assume the majority of those operations were indeed S9s, so it totals to about 2.1EH, that is a whopping amount of hashrate for the average joe like most of us, but it's nothing as far as the total hashrate is concerned, 202MW in Kazakhstan is A LOT of power given that the total the generate is below 20,000MW,  in the U.S for an example, 202MW is just peanuts.

Price did recover a bit, however, this invasion is likely going to be bad for difficulty and here is my logic.

When Abkhazia claimed its "independence" from Gorgia and only Russia declared it as an such, the central goverment of Gorgia could not stop supplying electcity to Abkhazia because that will mean that they recognize it as an independent state.

Mean while, they could not collect any power bills because well, you guessed it, the Russians are controling that part of the country, so that led to free power which was and still is used by many crypto mining operations.

The new separatist states in Ukraine will likey have the same faith since Ukraine said "our boarders have not changed", the new "goverments" will not have the tools to control electcity, those rich folks backed by the Russian troops can easly steal electcity and run thousends of miners for free.

2022 is not over yet, but I am sure as hell that this is the funniest statement I will ever read this year.

In fact, I am certain it will work just fine, how do I know? I tried it before (I forgot that I had it in the previous post).

I do not want to advertise any custom firmware, but just so you know, the "overclocking" on the stock firmware isn't all that great when it comes to power consumption/temps, so if you are in a cold place and pay no power bills then the stock firmware is your best option because of the no-fee.

OP, thierry4wd is a trusted fellow miner here, you can use his modified version as well.

Merit given for reporting back after the problem was solved.

The electromagnetic disturbance caused by that afternoon lightning strike probably did have an effect on your miner, it could have burned it but it seems to have fixed your issue, my guess is that your PSU caused the problem and not the hashboard itself, so just in case the problem comes back, check the PSU.

That same feature is found "hidden" on the S9i firmware version, just look for the same version/release date and it will be there.

Another option would be using the mutli-option version which can give you an extra 2 terahash.

And just so you know, the original s9 firmware works just fine on both the s9i and s9j, that is not true for s9k and s9se.

It will be highly unlikely for a second-hand S9 to be running just fine in 2 years anyway, those gears are pretty old and I wouldn't recommend them to anyone who pays anything above zero for power, if you have free power then ROI on S9 is usually 3-5 months, which is somehow pretty safe for an old gear like that, but if you count on it to run for a year or more, you will probably regret it.

With your power rate I wouldn't go above 40w/th, I wouldn't touch any of the Antminer 17 series, so that leaves you a few options, one which I can highly recommend would be M20s, it's in the 40w/th - 50$/th range, which isn't great by any means, but at least not as bad as the other newer gears.

There is no sign of any pic corruption in the kernel log, nor in the OP's brief explanation, I would leave such troubleshooting as last in almost all cases.

---

OP, you don't say if the miner runs fine and then stops or it just doesn't run at all, I can't find anything in the kernel log, and thus I expect the miner to be running just fine at least at the time of the kernel capture.

If it doesn't run at all, I would check the pool settings, if not, then please describe your problem in more detail so we can guide you.

Not sure if the odds are any better than Vegas, you need to factor in a few more variables that will somehow reduce the odds، it will not be exactly 1 in 2.

But hey i say this because i do not have an extra 100k to play with, value is subjective, since your friend gamles with 6 digits then why not.

Time is irrelevant in your question, it does not matter if you spend the 100k in 2 minutes or 2 weeks, it is the number of shares or attempts.

So an easy way to answer your question is to look at the average daily profit per th, which now about 173 dollars, so your 100k can get you 578 ph for 24 hours straight ( ignoring all the other variables which i can tell you about in a different post).


That amount of hashrate needs on average 2 days + a few hours to hit a block, so your 24h chance is 1 in 2.xx.

**Need to be on my pc to give you exact figures, but these rough figures should be good enough to answer your question.

Another different way is to look at it is in fiat value, the current block value is about 250k, if you invest 250k in hashrate your chance is 1 in 1, if you invest 25k it is 1 in 10.

Of course this is all just theory and luck will be all that matters, but IMO it is very unwise to gamble with half a block worth just to hit a block, the risk to reward ratio is just terrible, you may hit 2 blocks and you may hit zero blocks.

The way most of us do this is risk almost nothing in hopes to win everything, it makes a lot of sense that way.

You seem to be underestimating the current difficulty value, 5ph is just close to nothing, it has a chance of 1 in 41,396 at every block, should difficulty remain flat (which it won't), it should take on average 287 days for 5PH to hit a block, so not hitting a block with 5ph that ran for 1 or 2 days is just pretty normal, you should be surprised if it DID hit a block.

It's very unlikely that OP is related to Vnish/Asic.to, he is just sharing his experience and maybe "possibly" promoting his Youtube channel, Asic.to has an official account here and I highly doubt marc would create a newbie account just to promote his "already famous" firmware, he would do it his main account. I also highly doubt that OP has the slightest clue that this is a modified version of Cgminer, 99.99% of people don't know.

Of course, I am not commenting on any "license violation" aspect, I am just saying that the majority of folks don't care about it, and that includes the main developer of Cgminer Con Kolivas, heck, not even Jeff Garzik who wrote Cpuminer (which the former forked) seems to give a fudge about people using his code to make money out of it.

It is unethical and illegal in some countries, but not everyone is willing to provide for free so this isn't a black or white situation, the original devs stopped working on the code, Bitmain uses Cgminer without providing the source code for all MOST of their firmware versions, and their firmware sucks, Vnish and the other guys took advantage of this and created a better version (of course, while violating the license), people are happy to pay fees to enjoy all the extra benefits they get, if Cgminer as is, or Bitmain's "improved version" was as good - nobody would use these custom firmware, but people paid tens of thousands of dollars for mining gears that came with a stupid firmware, you can't blame them for using custom firmware.

You want to hear the funnier part? The PSU itself is not under warranty, if you send only a PSU to bitmain they will not fix it.

NFW, i am pretty sure it's mainly poor quality aka cheap components, also a lot of it has to do with the bad cooling design since some folks started to get a lower failure rate when they improved the PSU cooling.

I see many people now replace these apw12 PSUs with another brand like the one made by Alpha, it is 4kw and seems pretty solid, problem is it only runs at 277v which is not an option for many of us.

You are right, someone recently reported a 25% failure rate on s19s PSUs, they seem to have fixed the heatsink/chip solder issues they had with the 17 series and now started to screw with the PSUs.

Line of sight is everything, good luck getting anything close to that range if you won't be cherry-picking your two points, the nature of earth is just "not so flat", we did manage to get connections close to 80km with Ubiquity but one of the antennas was placed on top of a very, very tall tower.

OP I mined for 2-3 years without internet on site, but the farm was connected to the internet via a P2P setup, latency wasn't that bad and I hardly got any rejected/stale shares, your idea should work " at least in theory".

See Blockstream satellite ground stations are connected to the internet, you buy your own base station/dish and you connect to one of the satellites and those satellites keep your node synced with Blockstream ground stations that "are connected to the internet".


What you want to do here is actually have your own satellite ground station and not just a base station, and then once you hit a block, you want to transmit that to the satellites in space for them to re-transmit that block back to the earth so the block can be broadcasted to every mining node for them to stop working on that block.

Latency aside, this isn't a DIY project that can be done with no funding, if you can rent a satellite space and build/buy an uplink transmitter that can transmit blocks to the space -- then half the problem is solved.



BlockStream satellites do receive blocks from their own ground stations, you can't send them your blocks even if you had the means to do it.
