Привет!

Я ведущий разработчик форка вот этой штуковины: https://github.com/stratum-mining/stratum

Что-то у нас в проекте с финансированием получилось не так, как ожидалось поэтому я в поиске новых релевантных проектов.

Обладаю всеми необходимыми знаниями и навыками.

Is it true that there's absolutely no documentation available anywhere for the Antminer S19 API?

Hey guys! I've encountered an incredibly strange situation:

it seems that there's no public documentation for the API of Antminer S19 with stock firmware - I'm shocked and refuse to believe it.

Tell me, is this true or not?

Native firmware, I think.

We dont change firmware.

Is it possible to do with native firmware? It's critical for my case?

That is our Antminer models:

Antminer E9       
Antminer K7       
Antminer KA3       
Antminer KS5       
Antminer KS5 Pro       
Antminer L7       
Antminer L9       
Antminer S19       
Antminer S19 Pro       
Antminer S19 XP       
Antminer S19j       
Antminer S19j Pro       
Antminer S19k Pro       
Antminer S21       
Antminer S21 Pro       
Antminer T19       
Antminer T21       
Antminer Z15 Pro

(list is'nt complete)

Парни, а топику-то уже более 10 лет! 

Я так понимаю, он вполне сможет пережить всех нас 

Кстати, я помнится тоже сюда что-то писал году в 18-19, только не помню уже что именно ))

С годами становится откровенно все равно на всю эту чушь - главное чтобы не бомбили

Ведь если посмотреть беспристрастно - какая разница простому человеку кому платить налоги: Москве или Киеву?

В том же Крыму за эти 10 лет ничего по сути не изменилось. Ну так, по мелочи: там дорогу подлатали, здесь больничку отремонтировали, но в целом-то - как жили так и живут. Кто регулярно мотается в Крым - прекрасно об этом знает.

Ну а коли так:

- В чем суть споров-то?

Guys, hello!

We have a zoo of miners in our project, but we've only managed to find API documentation for WhatsMiner models.

We also have various Antminer models: L9, S19, T21, etc.

And, surprisingly, I haven't been able to find documentation for controlling them via API.

Our goal is to establish centralized management and monitoring.

Whoever gives good advice is a star!

Hi everyone! Is there an updated version of this guide available? For BC 28. Thanks.

Вопрос снят, там нужно в тему целиком влезать, без вариантов 

We are currently developing a pool based on SRI (Stratum v2) (I'm the tech lead).

We also want to support Fractal Bitcoin, but the documentation on docs.fractalbitcoin.io is clearly insufficient for developers. It's more like a marketing brochure than documentation like Grin's.

Could you please suggest a more comprehensive source of information on Fractal Bitcoin?

Perhaps you could share a contact who is knowledgeable on the subject?

Even just a good, up-to-date piece of advice would be helpful. Grin

Thank you.

Мы сейчас ведем разработку пула на SRI (Stratum v2) (я техлид)

Тоже хотим поддержать у себя Fractal Bitcoin, но документации на docs.fractalbitcoin.io явно недостаточно для разработчика. Она больше напоминает рекламный проспект, чем документацию 

Подскажите, существует ли более внятный источник знаний по теме Fractal Bitcoin?

Может поделитесь контактом, кто в теме?

Даже просто хороший актуальный совет сгодится 

Спасибо.

I'm currently developing a mining pool implementing Stratum 2 in Rust (SRI), and during development, the question arose of calculating a miner's hashrate based on the difficulty of the shares they submit. I conducted a small experimental study and found that the following algorithm provides the best accuracy:

1. I take the shares submitted by the miner over a period of time, say 10 minutes.

2. I calculate the difficulty (share_diff = max_target / hash) for each.

3. I find the share corresponding to the (1 - 1/e) percentile (this is approximately the 63rd percentile) in terms of difficulty.

4. I multiply the difficulty of the share found in step 3 by the total number of shares.

5. I multiply the result obtained in step 4 by 1/e (approximately 0.37).

6. I multiply by 2^32 and get the number of hashes that needed to be iterated through to find all these shares.

7. I divide by the number of seconds (for 10 minutes, this is 600 seconds) and get the hashes per second.

If someone understands code better (I don't vouch for the accuracy, it was generated by AI based on my description


I have questions:

1) Is this technique commonly known? And what are the alternatives?

2) Why does this even work? I have a lot of work on the project right now, and I don't have time to delve into theoretical mathematics, but I'm very interested in this story with the number "e" - why does this particular number work? Can this algorithm be written in any other way?

Thank you.

We are working with an engine based on https://github.com/stratum-mining/stratum - you are probably right, it's worth basing calculations on the target rather than the average hash_diff.

A real-world example: during local testing with CPUMiner, 50% of the shares come in with a difficulty between 0.05 and 0.15 at a rate of 10 shares per minute. However, episodically, CPUMiner calculates shares with a difficulty of 10.0 and even 40.0 - and this completely skews the hashrate calculation over 10-minute intervals. I've tried trimming extreme values in the calculations, but I still can't achieve acceptable accuracy between the hashrate reported by CPUMiner in its logs and the hashrate we calculate. I'm currently experimenting with different normalization schemes, but haven't found a suitable solution yet. So I thought - maybe someone has a ready-made solution.

We are developing a mining pool, and it would be beneficial for us to know the hashrate statistics of each worker over a 10-minute period to distribute rewards fairly. Essentially, we need the hashrate displayed by the miner's device to match the hashrate we calculate based on the difficulty of the shares (hashes) it submits.

Greetings!

During testing and calculating the hashrate of workers (in some bitcoin-app), we've encountered a challenge:

- The calculated hashrate of miners, based on the difficulty of the shares they submit, differs significantly (by several times) from the actual hashrate of the workers – both for ASICs and CPUMiner.

We calculate the hashrate as follows (this is pseudocode for simplicity):

```
diff = max_target / hash
total_hashes = sum(difficulty * pow(2, 32))
hash_rate = total_hashes / sec
```

Essentially, we determine the number of hashes required to find a hash of the required difficulty (`difficulty * pow(2, 32)`), and then we do this for all hashes found in the last 10 minutes, sum them up, and divide the sum by 600 seconds.

It seems like it should work.

However, in practice, CPUMiner, for example, finds shares with difficulties ranging from 0.01 to 10.0 within a 10-minute period. As a result, our formula leads to a hashrate that fluctuates wildly (by several times), deviating significantly from the actual hashrate.

Have you encountered anything similar? Could you suggest a solution or at least point us in the right direction for further investigation?

Thanks in advance to everyone who participates in this discussion.

Hi! I'm currently participating in a project developing a mining pool based on Stratum v2 in Rust. In 3-4 months we'll complete the project, and I'll likely be looking for a similar one. Could you tell me how much demand there is for this in the current English-speaking job market? How many available specialists are there in this field?

Hi!

When I try to connect CPUMiner with https://github.com/stratum-mining/stratum - its OK.

But if I try to work with WhatsMiner M30S+_VH20 then:


in WhatsMiner log, and


in Translator Crate log.

And in tcpdump:


What is going wrong?

How can I fix it?

Tnx!

Проблема. Две биржи сегодня отфутболили уже, включая bybit

Давно не имел дела с криптой как таковой, понадобилось оплатить один сервис.

Нужны USDT (немножко) на MetaMask, есть фиатные рубли в банках РФ.

Bingx отклонила KYC - "регион не тот".

На Binance вообще рублей не нашел.

Есть возможность прикупить USDT в телеге на @wallet но непонятно что с ними делать дальше.

В общем, вопрос из сабжа:

-- Как обменять рубли с карты любого рос.банка на USDT в MetaMask? --

Мерси-мерси если кто знает и поделится опытом.

Do you also work for free at work? Are you given food for free at the store? Or do we live in different universes?

We need bitcoins to withstand this onslaught of misinformation.

We need money to order the creation of videos. We need money to buy advertising sites. We need a lot of money.

But you're right - we also need volunteers who will spread the truth about coronavirus for free. You're right.
