3322  Bitcoin / Development & Technical Discussion / Re: Bitcoin Block Halving on: October 25, 2020, 10:38:13 PM
There are no circumstances to reach them in just a short period of time. As long as difficulty changes every 2016 blocks, it means that even if the total mining power gets doubled, the difficulty will get doubled as well.

But difficulty adjustment alone can't maintain the 4 years halving theory, it's only meant to get it as close to that as possible to maintain a known inflation rate, correct me if I am wrong on the following:

Theoretically speaking we can have a bitcoin halving every day (or even an hour)

Difficulty adjustment is limited by a factor of 4 in this code, so this can only slow miners by a factor of 4 in the best-case scenario

Code:
 // Limit adjustment step
    int64 nActualTimespan = pindexLast->GetBlockTime() - pindexFirst->GetBlockTime();
    printf("  nActualTimespan = %"PRI64d"  before bounds\n", nActualTimespan);
    if (nActualTimespan < nTargetTimespan/4)
        nActualTimespan = nTargetTimespan/4;
    if (nActualTimespan > nTargetTimespan*4)
        nActualTimespan = nTargetTimespan*4;

So it can't be more than 400% of the previous epoch and not less than 25%, which means if hypothetically the hashrate keeps going real fast ( 40 times higher constantly with every adjustment) we will be able to mine 210,000 blocks as fast as our hard drives can handle.

Imagine the following:

Diff = 1
hashrate = 10
2016 blocks were mined in 1 minute ( I mean all of the 2016 blocks)
Diff can only be 4x so:
Diff = 4
hashrate = 400
2016 blocks were mined in 1 minute

And so on, so forth! I can't find anything in the code that will stop miners from mining all bitcoins in no time, I believe Satoshi knew this wasn't going to happen because of the nature of people, money, and technology limitation, not because of the code itself.


Now for something like this to happen, we will need a new technology outside of this universe because the current 130Exahash hashrate is impossible to double in the course of a few months, let alone do 40x.

You will notice that the further we go, the closer we get to that 4 years mark because the larger the hashrate the less impact we can have on it, eventually we should be able to hit a very close period to that 4 years plan.

I wanted to confirm the theory of the ending of the rainy season in China from a different point, and I can now tell you with confidence that we have thousands of S9s going offline, the price of those used miners in China has dropped quite a bit since the past week, which means a good number of mining gears "suddenly" got into the supply circulation of used miners in China.

The good news: Price is still at the 13k level, this epoch will most likely be negative. The bad news: Many S19s and S19 pros will be delivered soon (need more information regarding this.
3325  Bitcoin / Mining support / Re: APMinerTool Compatability with 19 series on: October 25, 2020, 07:11:39 PM
I've tested on my S19-Pro and no it doesn't work. Just shows as Status: None

I wonder what has changed in the S19 series as far as the firmware/software/API level is concerned, I mean it's not like they upgrade the tool after every generation, also other software like AwesomeMiner do work on S19 as far as I can tell, also the BTCtool you mentioned above, I highly doubt any upgrade was needed by these tools, it must be something wrong with the APminer tool itself, someone should send them an email and see what they have to say.

Jokes aside, this has nothing to do with "where" you try to post s-t-r-a--t-u-m-+-t-c-p, Kaspersky will still flag it, even if you send it through a PM,  mprep has explained the issue in a perfect manner, please refer to his post
3327  Bitcoin / Mining support / Re: Knc miner data cable on: October 24, 2020, 07:38:23 PM
Why not take a picture of the miner and post it here?

Anyway, the majority of Asic miners use 18 pin ribbon cable for data transfer, and this is how they look like:



Image source: https://www.ebay.com/p/14012711023 , it's a bit overpriced tho, you can find it for a lot cheaper, if we were in the same country with no international shipping required I would give them to you for free, I have a ton of them from my dead miners.

Thank you for your response. The miner does show alive. I do have another question. I noticed the frequency per card is lower when mining on Ckpool. Is that because Nicehash overclocks even when genuine Bitmain firmware is installed?

I highly doubt that Nicehash has any control over the frequency of your miner's hash board, you are probably aren't running a fixed-frequency firmware and this is why the frequency would fluctuate from time to time, I know (without any rational explanation) that mining to Nicehash seems to cause a much higher failure rate than the ordinary pools with fixed difficulty, but I don't think that has anything to do with the frequency unless I am missing something.
3329  Local / التعدين / Re: مشروع ماينق بول يخدم المجتمع العربي on: October 23, 2020, 10:45:41 PM
بالاضافة الى ماسبق ذكره اود ان اضيف امر مهم جدا جدا وهدا الامر غائب على معظم الناس وهوا امر يجب ان يعرفه مالك حوض التعدين والمعدنين نفسهم.

مبدئيا يجب ان نعرف ان زمن احواض PPLNS قد انتهى وان احواض PPS تسيطر على نصيب الاسد من التعدين, مما يعني ان اي حوض تعدين جديد يجب ان يكون PPS لكي يكون له فرصة في البقاء, ولفهم الفرق بين الطريقتين يمكن قراءة هدا الموضوع https://bitcointalk.org/index.php?topic=5260949.0

طبعا ان قمت بقراءة الموضوع اعتقد انك فهمت ان حوض PPS يدفع كل share حتى وان لم يجد اي بلوك, يعني صاحب الحوض قد يدفع من جيبه, ونظرا لان تعدين البتكوين مبني على الحظ يمكن ان لا تحصل على بلوك لفترة طويلة ولكن محتاج لدفع البتكوين لكل المعدنين, مما يعني انه يجب ان يكون لديك رصيد يغطي هده التكلفة, قيمة الرصيد طبعا ليست عشؤائية ابدا.

قام عالم الرياضيات والخبير في مجال الكريبتو والتعدين Meni Rosenfeld بكتابة ورقة بحثية يشرح فيها كل التفاصيل المالية المتعلقة بالاموال وهدا رابط الورقة https://arxiv.org/pdf/1112.4980.pdf

لالخص عليك الجزء المهم الذي يخصك فهوا هده المعادلة R =B ln 1δ2f (يوجد صعوبة في نسخ ولصق المعادلة الموجودة في الصفحة 38 ولكن ساكتبها بطريقة مبسطة في الاسفل)

(6.25  *ln 1000) / (2*0.025) = 863.46 BTC

الاحطياتي اللازم = ( مكفاءة البلوك * فرصة الافلاس التي تحددها انت) \ ( 2 * عمولة التعدين التي تأخدها من المعدنين)

لنقم بتطبيق المعادلة المعطيات:

مكفاءة البلوك = 6.25 بتكوين
فرصة الافلاس = المتفق عليه انها يجب ان تكون 0.1% وهي 1 في 1000  (يمكن ان تكون 50% فرصة افلاس ولكن وقتها حظا سعيدا بأن تجد اي شخص مستعد ان يخاطر معك)
عمولة التعدين = 2.5% (هده اقل عمولة موجودة الان ولكي تنافسها يجب ان تكون مثلها او اقل)

المعادلة = ( 6.25*1in1000)  قسمة (2 * 0.025) = 863.46 بتكوين

بعض الاحواض قد تدهب الى احتمالية 1% للافلاس اي 1 في 100, وبتطبيق المعادلة تكون محتاج 575.64 بتكوين فقط ( حلوة فقط هدي  Grin).

يعني بالملخص ان كنت لاتملك هدا المبلغ من البتكوين لن تتمكن من انشاء حوض تعدين "امن" لك وللمستخدمين" وخيارك سيكون PPLNS وها غير "جداب" ولكن طبعا لايحتاج الى احتياطي, فقط احتياطي بسيط لتشغيل السيرفرات وغيرها.



على العموم يمكنك استخدام CKpool  فهو Open-Source ولكنه يحتاج لبعض التعديلات https://github.com/rsksmart/ckpool

والكود هدا قام بكتابه Ck عضو موجود معنا في المنتدى ويقدم خدمات انشاء احواض التعدين يمكنك التواصل معه https://bitcointalk.org/index.php?action=profile;u=19971
يوجد اي شخص اخر محترف "شريكه السابق" وهوا Kano https://bitcointalk.org/index.php?action=profile;u=36044

ملاحظة : بالنسبة ل Kano فهوا شخص ذو اسلوب فض قليلا ونحن دائما نتشاجر ولا نحب بعضنا البعض  Grin ولكنه من وجهة نظري على الاقل يمكن تصنيفه في قائمة افضل 5 مبرمجين لاحواض التعدين في العالم بأسره.
3330  Bitcoin / Mining speculation / Re: Get Miners from China while avoiding the Tariff? on: October 23, 2020, 10:18:40 PM
Are there high import tariffs from the EU to US?

Someone mentioned that as long as the miners are made in China, it doesn't matter where do they ship from, the tariff will still have to be paid, so unless the gears are made in Malaysia nothing "legal" can be done to avoid the tariff, not sure if that applies to both new and used mining gears.

You might find a facility in Iceland or somewhere also with cheap electricity?

I think better deals are found in China, the electricity cost in China is cheaper and you don't actually have to pay any import tax or even international shipping, finding the right facility that can be trusted isn't easy at all, but there are plenty of them.
3331  Bitcoin / Pools / Re: [∞ YH] solo.ckpool.org 2% fee solo mining 256 blocks solved! on: October 23, 2020, 06:38:00 PM
You got the wrong port and location for the last one, it's actually

stratum+tcp://rfpool.org:3333 (Germany)


This is a passthrough service provided by o_solo_miner, not sure if Ck has anything to do with it, but I have tried it and it works flawlessly, this is great for those countries who piss off the U.S government and are banned from accessing U.S based servers, sort of a mining VPN.

This pool is also great to diagnose issues some people have with less reliable pools out there, and the fact you don't need an account to mine and verify hash is a huge plus.

Exactly, I have Cksolo pool as a back-up pool on hundreds of miners, it's a great way to tell if your miner or internet is having issues or it's the primary pool, it's easy to test and it's one of the few (very rare) mining pools that allow you to mine and see your mining status without having to go through the registration and creating worker names process.

3332  Other / Meta / Re: Kaspersky blocks access to certain topics on Bitcointalk.org on: October 23, 2020, 06:16:19 PM
What browser are you using and do you have any other relevant/active plugins? Based on what the site says it could be an autoredirection tool from cloudflare (but I'm not sure if that'd be considered a risk).

No plugins whatsoever, the issue only appeared a few moments ago, nothing has been updated/changed, I am using Chrome.

I think I know how the problem happens, I just don't how Kaspersky is considering it a risk.

I was trying to reply to this https://bitcointalk.org/index.php?topic=5237323.msg55438812#msg55438812

I quoted the part which contains URLs from Artemis3's post, and the block-message appeared, when I posted this topic it went through without an issue, so I figured out it had to be something with the content of my post, I removed the URLs quotation and it worked



Never had an issue with Norton & Malwarebytes both of which I find give the most false positives.

Dave can you try to quote Artemis3's post and see if your security software will block you.

Edit:

It's actually the "stratum+tcp" part that sets the alarm off, basically, I had to turn off Kaspersky to be able to post the following line.

من المستحيل التكهن بالسعر بنسبة 100% وهدا مايجعل نقطة انني انصح شخص بالبيع او الشراء شي شبه مستحيل, النقطة الاخرى التي يجب فهمها هوا الهدف من شراء البتكوين, انا كان السؤال هل من الجيد الشراء الان للبيع بعد 3 سنوات؟ ستكون اجابتي نعم, اما ان كنا نتكلم عن الايام او الاسابيع القادمة فالامر بكل تأكيد سيختلف.

شخصيا لا احب الحاق بالقطار بعد ان يبدا بالتحرك, الشراء كان يجب ان يكون من المستويات المنخفضة وهده المستويات هي مستويات بيع وحجز ربح للمتداولين, طبعا هدا لايعني انني متاكد بنسبة 100% ان السعر سينخفض في الساعات القادمة ولكن لاني اشتريت من مستويات منخفضة فبدأت بالبيع التدريجي.

3335  Other / Beginners & Help / Re: CryptoCurrency Without Blockchain on: October 22, 2020, 11:59:43 PM
OP is talking about Avalanche protocol, a very interesting idea which was introduced by a "random" person/team, something similar to how Bitcoin started, the protocol "looks" like it's all sunshine and rainbow but this isn't the case at all, its largest obstacle is Sybil attack, which means it has to "validate" or "whitelist" all nodes that want to participate, now in order to do that, you will need to use some POS or POW features to ensure that no Sybil attacks are easily performed.

BCH implemented Avalanche protocol as a pre consensus protocol which runs alongside POW (that's why you can't double spend on BCH anymore), but this is way too early to judge if that will succeed, it could as a side-chain solution, but most certainly it can't replace POW and blockchain.

Thanks for sharing the video, was fun to watch, found this video as well https://www.youtube.com/watch?v=zY8CjwGQFrA , he got 2.3g of gold ($140) out of 1KG worth of chips,  I think unless that is done on a very large scale it isn't really worth doing.

That's super cheap if china is not too far maybe I'm going to buy some.

Not sure how $15-20 for a scrap miner is cheap, for how much do you think you will be able to sell it for? don't forget that extracting whatever usable materials will cost you money as well.
3337  Bitcoin / Mining speculation / Bitcoin ASIC miner scrap value. on: October 22, 2020, 09:27:48 PM
A friend of mine sent me this video > https://streamable.com/jkhctx   (didn't find a better website to upload the video, not sure about the ads in there, could be NSFW). He said the scrap value for Antminer S9 is between about $15 and $20 in China, how feasible does that sound where you live? I am curious to know.

Here is a post by DaveF:

Grab a hammer and knock off the aluminum heatsinks, you can probably get $0.25/ pound for them.
The boards with chips will probably get you $1.00 / pound.

based on this, I hardly think the miner is worth $10 in the best-case scenario,  two fans are probably worth $1.5 each, what else can be sold? do these miners have any form of gold? I know cell phones have like 0.03grams of gold on average which is about $2 worth but not sure about these gears.

Hey everyone. I'm new. My miners keep hitting blocks in Nicehash so, I had to put at least one on here.

They keep hitting blocks on NiceHash because they mine Altcoins with very low difficulty, there is no "keep hitting blocks" when you start mining BTC only, so don't set your hopes too high.

I just want to make 100% sure I'm doing the "mining address" correctly. I put it as the bitcoin wallet on my Ledger Nano X. I've noticed some posts in here and the address doesn't start with bc1. Should I use a different address than the wallet address I am using? I also put .worker# after my wallet address. That will work, correct?

Addresses that start with bc1 bech32 (native Segwit) addresses, as far as I know, Ckpool allows that kind of address, as long as your miner status shows "alive" next to cksolo pool and you see your miners getting accepted shares on the pool status page, then you are good to go.

So far a very solid drop. 12% this is nice.

Even though we went up about 15% in price, the difficulty is still dropping, which suggest that those thousands of S9s that were running on hydropower in China have actually left (at least a large portion of them), I am pretty confident that we will have a drop in difficulty for this epoch even if the price was to shoot to $15,000, what happens in the following epoch will, of course, be different depending on the price.

the 55-60 watt gear like the A1066 look okay.

I wouldn't really worry about 55-60 wat/the gears, they are a drop in the ocean, the big player is "S9", the moment they become profitable at 4-6 cents again, a huge chunk of them will come back online to boost the difficulty.
