90% if a Profesional with the right tools and spare parts fixes it, slim to nothing if a regular person like myself does.


It can run with any number of working hashboards.


not the most power-hungry, some miners consume up to 6000w, the second part however is somehow correct, this needs 220-240v, but 15A not 10A.


The PSU can't be used on other miners, not even other miners from the 17 series itself.


Can you sell it for $20? this is the only question I would be asking.

Do you see the rewards in your pool balance? the minimum payout is 0.005BTC are you sure you have that much? because that needs like 1.8PH for 24H, also, if you have just updated the payout address, your funds will be frozen for 3 days for some security purposes, and after 3 days if your payout => 0.005 btc it will be sent out.

"The devil is in the detail", the title says "is paying" so they were probably referring to that exact time of when they posted the topic, otherwise, it makes no sense, they have also made such a claim long ago when they were paying some crazy high number like 7x or so, and they were not lying about it, it did last for a while and I personally made some good profit on those days.

Whattomine.com keeps a good track of NH payments, the 3-day average for their Asicboost was 103%, and for non-ASICboost it was 163%, not sure why those folks pay that much to rent non-Asicboost, probably someone mining/attacking some small coin, but I have also witnessed many periods where Nicehash paid lower than 100% PPS, so it's a game of luck unless you are going to chase profitability, besides, you can't really connect to NH using a mining proxy (I have tried several before), so only small miners can actually use it.

لست على دراية تامة بطريقة عمل UST ولكن اعتقد الفرق الاهم هوا كمية الضمان مقارنة بالمعروض, عمله DAI تطلب 150% من قيمة العملة لانشاءها يعني انه هناك مجال ووقت كافي لبيع العملات الضامنة مثل الايثيريوم والبتكوين, على عكس ماحدث لعملة لونا.



الامر يعتمد بالدرجة الاولى على كمية الاحتياط وجودة الكود وسرعة تصرفه في حال انهيار احد الاصول, عملة داي اتبت جودتها لسنوات ولم تفقد اترباطها بالدولار حتى عند هبوط الاصول 20-30% في يوم واحد, طبعا هدا لايعني انه لايمكن ان تنهار, خصوصا وانه وللاسف حوالي 40% من اصول عمله DAI مبنية على USDC وهدا شي سيء نسبيا لانه في حال انهاير USDC سيكون من الاستحال حفاظ DAI على قيمتها 1:1, ربما تحتفظ بقيمة 1:2 نظرا لوجود عملات اخرى في الارصدة مثل البتكوين والايثيريوم, ولكن تبقا هناك خطورة على اي حال.



لا احد يمتلك العقد, من يتملك القدرة على تغير العقد هم من يملكون Maker , كلمة لامركزية لا تعني عدم القدرة غلى تغير اي شي, بل تعني ان قرار التغير لايكون في يد شخص واحد او كيان واحد, والا فنفس المنطق ينطبق على البتكوين, ماذا يمنع المعدنين واصحاب العقد من غير اجمالي المعروض من البتكوين من 21 مليون الى 50 مليون مثلا؟ لا احد يمنعهم, ولكن التغير يتطلب موافقة الاغلبية, ونظرا لان كل شخص يمتلك قرار التصويت سوف يصوت للافضل بالنسبة له, فاحتمال ان يقوم معظم الناس بزيادة عرض البتكوين هوا ضعيف جدا فكلهم يريدون ان يحافظو على قيمة اموالهم, نفس الشي ينطبق على من يمتلك القرار في عملة DAI.

الفرق المهم هنا هوا انه لايوجد شخص او شركة تمتلك القرار النهائي فيما يحدث للعملة, فمثلا يمكن للحكومة الامريكية ان تطلب من Centre وكوينبيز ان تجمد ارصدة معينة لاشخاص معنين, ونظرا لان تلك الجهات هي كيانات موجودة ومعروفة فعليها تطبيق القانون, ولكن لايمكن للحكومة الامريكية ان تطلب من ملاك Maker بعمل شي مماثل لانه الاف او ملاين الاشخاص يتحكمون في تلك العملة, طبعا في حال استحود شخص ما على كمية ضخمة من العملة سوف تكون قدرته على تغير الامور اكبر, ولكن يمكنه الاستمرار في اخفاء هويته وليس محتاج لتطبيق اوامر اي احد.

بالمجمل عملة DAI اامن بكثير من العملات الاخرى, ولكن وجود كمية كبيرة من USDC في خزينة تلك العملة هي امر سيء للغاية, طبعا يوجد ميزات عديدة لوجود عملة مستقرة داخل سلة العملات, ففي حال انهيار اسعار الايثيريوم والبتكوين ستكون نصف قيمة العملة مؤمنة من ال USDC والنصف الاخر يمكن تداركها بسهولة نظرا لوجود كميات اكبر من USDC والعملات الاخرى, ولكن ان حدث مكروه لعملة USDC نفسها فبكل تأكيد لن تكون DAI في مأمن تام الا ان تمكن بروتوكول العملة من التصرف بصورة صحيحة والتخلص من من USDC بشكل سريع جدا.

The new signature design fits better on phone screen, but still the last part is missing, it shows (ChipMix) and no logo on the right side of the screen, can we make the font size for "reinvented" smaller to fix that?

Since the miners are now almost all mine whiting a pool, the pool needs to generate a new block template and send new work to the miners that are already working on an empty block template, so it is likely to delay that for a while ( probably a few seconds) to allow shares coming from those miners before sending the new work.

Also since there is nothing in the protocol that governs this process, each pool is likely handling it a bit differently


When I made my analysis on the subject, I found that all pools mined empty blocks except for Kano.is, kano publicly stated that his pool code won't send an empty block template to miners unless his mempool is empty which is more like 'never'

Agreed, I think he meant it this way, but unfortunately, even with that meaning it's pretty much false, your chances of hitting a block mining solo are exactly the same as your chances of mining the equivalent of a whole block while mining to a pool.


With everything being equal, if your miner with 100% luck is supposed to hit a block in 10 years, if you mine to a pool for 10 years and combine your payouts, you will end up with a whole block reward.

LoyceV's notification bot notified me about the post by Don Pedro Dinero, so I used google translator to read the topic and found some interesting stuff, the last portion of your post which translates to the following (of course, assuming google translator is accurate)


You simply can't guarantee, it's just wild guesses unless you are the person himself, however, it's not really "deliberately to try to gain time" it's more like "trying not to waste time and hash power".

See, there is nothing in the protocol that prohibits users from mining empty blocks, it's just the fees incentives that ensure transactions are included in blocks, it makes no sense for any rational miner to leave money on the table "intentionally" unless they want to prove something (like the debate/war over block size when IMO bitmain was mining empty blocks on purpose just to prove a point), aside from that, empty blocks are just a part of the game, I don't think it's wrong or even unethical to mine empty blocks.

The only way you can avoid empty blocks (assuming there are pending transactions which is the case 99.99% of the time) is to intentionally waste money, pulling out the last block header and the details you need to start mining the next block takes less than downloading the whole block, checking the old transactions and creating a new block template that has transactions.

Kano ( a pool operator) said it takes less than 200ms to do that, you can find other sources who would claim 1 second or any other number, it actually doesn't matter because time = money, even going with the assumption that its 200ms, and as a pool, I am supposed to mine 20 blocks a day, by ensuring that I don't mine empty blocks it means I will be wasting 200ms*20 every day, there is no need to translate that to the actual BTC earnings or $, we know for certain it's >0.

so despite it being a few seconds/minutes of "otherwise wasted hash power/time" what do I gain by not mining empty blocks? this is the question that needs to be addressed while keeping in mind that just because I mined an empty block, it has no effect on the time it takes to include your transaction, if I somehow hit a block during the first 200ms of receiving the previous block header, it doesn't mean I could have waited 300ms to include your transaction, it also doesn't mean that I or any other miner can't find a block 2 seconds later and include your transactions.

When all these things are put together, it seems very irrational not to mine empty blocks, not by actually doing it intentionally, but just as a result of not wasting a single hash you have.

Of course, the counterargument is that if you don't actually check all the transactions in the block, you could very well be mining on top of an invalid block (one transaction could be invalid and that block is invalid and so is yours), that's a great argument, but we need to keep in mind that me trying to solve am empty block while downloading and checking the previous blocks at the same time, so two scenarios:

1- The previous block is valid > I started and have not wasted time.
2- The previous block is invalid> I started and have not wasted time but if I hit a block it's useless.

Notice how it makes no difference in regards to wasting time because the other option is simply wasting time checking the block whether it was valid or not, I rather risk mining on top of an invalid block than seeing my hash power wasted doing nothing, also, it does make sense to trust the previous block for 200ms since it's for their best interest not to include an invalid transaction in their block or else they lose the whole block.

Of course, some people think this is unethical and everyone must check every transaction before mining the next block, to me, the theories and explanations just don't add up, but that is just me.

ساقوم بشرح مختصر وبسيط لاعطيكم فكرة جيدة عن الموضوع وتم نتوجه للاسئلة الدقيقة.

عملة داي تعمل بطريقة بسيطة ومعقدة في نفس الوقت, لنبسط الشرح, دعنا نقول ان (صلاح) هوا من يقوم بانشاء عملة DAI, صلاح يمتلك smart contract على شبكة الاثيريوم, حيت يقوم هدا العقد بأنشاء 1 DAI لكل 1$ من الايثيريوم يصل الى عنوان العقد, ويقوم بارسال 1 DAI لعنوان الشخص الذي ارسل الايثريوم.

يعني, ان قام (جلال) بارسال 6 ايثيريوم, وكان سعر الايثريوم الواحدة 100$ في ذلك الوقت, سيقوم العقد الذكي بانشاء 600 عملة DAI وارسالها لعنوان جلال, اذا الان العقد يتملك 6 ايثير والتي بدروها تساوي 600$ في مقابل 600 عملة DAI يمتلكها جلال, اذا بكل بساطة 1 DAI = USD لانه في اي وقت يمكن لجلال ارسال 600 DAI للعقد الذكي والحصول على 600$ في هيئة 6 ايثير.

طبعا فعليا لايقوم العقد الذكي بانشاء 600 DAI بل يقوم بابقاء التلث تقريبا من قيمة الايثير (تحوطا من هبوط سعرها), يعني جلال الذي ارسل 6 ايثير بقيمة 600$ سوف يحصل فقط على 400 DAI , مما يعني ان عملة DAI سوف تضل محافظة على قيمتها بالدولار حتى تنحفظ قيمة الايثيريوم الى مادون ال 400$.

حسنا ماذا سيحدث في حال انخفض سعر الايثيريوم من 100$ الى 90$؟ هنا سوف يحدث شي من اتنين

1- يقوم جلال باضافة 10$ من الايثيريوم وارسالها الى العقد للمحافظة على قاعدة الثلثين
2- او ان يقوم (محمد) ببيع 0.11 ايثير (قيمتها 10$ بسعر 90) مقابل عملة DAI

ماايحدث في الخطوتين هوا محاولة ابقاء 1.5 دولار من عملة الايثيرم في حساب (صلاح) مقابل كل 1 داي, وفي حال انهيار سعر الايثيريوم من المفترض انه سيتم ضخ عملة ايثيريوم او حرق عملة داي للمحافظة على الكفة.

طبعا لايوجد (صلاح) في هدا الموضوع, صلاح في مثالنا هدا هم من يمتلكون عملة MakerDAO هم من يقومون بتحديد نسبة الضمان والرسوم.

Exactly, even at current gear prices ROI is close to 1 year with free power, with 7 cents even with the latest gears, it still is more than 2 years, so it will go beyond the halving and the 2 years could very well be 3 or 4 years, or never.

Still however safer to buy now than when we are in the middle of the bull cycle or closer to the end.

$5348 is M50 (no S), the S version is more expensive,  $3180 for the 130th delivered, so for your set up it's 6k+ too risky for a test phase of your project, and IMO, it's not worth the price difference, it's just 1-2w/th.

Anyway, the prices they quote you are pretty accurate, for 25 pcs I can do lower than those prices, for MOQ of 2 pcs, I can probably do the same prices above, or slightly lower, the thing is, BTC went up 8% in the last 24 hours, so tomorrow prices are probably going to be higher, it's insane how fast gears react to price increase, but pretty slow to respond to the opposite.


Back to diff.



Too early to judge, but things are looking ugly, seems like the news/rumors that Russia (as a state) is building some large mining farms is real.

شكرا ع انشاء الموضوع, في الواقع الغرض من تعليقي في الموضوع الاخر هوا توضيح بعض الامور بخصوص طريقة عمل DAI وليس كتابة شرح مفصل حولها, للاسف لا امتلك الوقت الكافي لصياغة الموضوع بالطريقة التي تليق به, لذلك اتمنى منك او من احد الاعضاء كتابة الموضوع وسأكتفي بالاجابة عن بعض الاسئلة المعينة التي يصعب ايجادها عن طريق البحت في محركات البحث, وربما في الفترة القادمة عندما اتفرغ اكثر للمنتدى يمكنني كتابة شرح مفصل عن العملة.

عملة DAI لايوجد لها اي غطاء حقيقي من الدولار, العملة تكتسب قيمتها من قيمة العملات المحوزة في MakerDAO's, وهده العملات على سبيل المثال لاالحصر هي ايثيريوم , بتكوين, USDC وغيرها.

لايتم طباعة اي عملة DAI الا بارسال قيمة اعلى من القيمة المطلوب طباعتها لل smart contract باحد العملات المطلوبة, قيمة تلك العملات ضد الدولار هوا مايهم, ولا حاجة لوجود غطاء بالدولار مباشر.

يمكن القراءة عن طريقة عمل هده العملة الرائعة, وفي حال وجود اي اسئلة بخصوصها يمكننا انشاء موضوع خاص بها لاقوم بالاجابة عن تسائلتكم.

This is not true, the m50s ranging between 25-26w cost 6-7$ more per terahash compared to the m30s+, the 50 series (without the s) ranging between 27-28w cost 3-4$ more per terahash.

Nop, it is a fake website, the real one is http://whatsminer.com

What is the size of the cable you used in Germany, if it's below 2mm2 that might not be a good idea to run it on 120V and draw 1000w or so, also the socket type is different, Germany uses type C, and type F sockets, so you will likely have to buy a new cable that fits U.S sockets and can deliver 1000-1200w on 110v, but keep in mind that the PSU can only run the miner at full speed when plugged into 220v.

You can either use the multi-option firmware to underclock the miner, or simply unplug one of the there hashboards to fall below 1000w and you should be good to go.

That is good news then, you will be limited by the PSU's max limit which I believe is 3800W, so for your two M30s+ you should get anywhere between 110th to 115th without going past 3700W on each, so that be a total of 7400w which is slightly above 50% of the tank, and 220th-230th.

For a medium sized house, with the correct engineering, those 25k BTU hour should keep the house warm in the winter, while generating nearly 500$ monthly, not sure how much folks there spend on heat during the winter, you are going to have to run a lot of maths.

You can't, it just happens when it does, in theory, lower power mode should increase the lifespan of the miner, but is it going to be 6 months instead of 3, or 13 days instead of 12, you simply can't tell.


I don't own any of those, but I can assure you the low power mode works and does improve efficiency, in fact, most custom firmware do the same long before the release of the stock firmware, every gear should gain some efficiency when underclocked, the manufacturer tunes the gears to get the perfect match between a few factors (total hashrate, temps, warranty, and efficiency) they want the most hashrate at the best efficiency that can reasonably run safe thought the period of warranty and a few more months/years.

They can tune a 30w/th gear to do 25w/th but that will mean a lot less hashrate, which means they probably can't sell it for the same price despite the 5w improvements, they can also turn a 100th gear into 120th gear, but that means an extra 5w/th or a higher power need than their PSUs or what most clients want, so this "balancing" of things isn't always the best for everyone.

It's actually a pity that they announced the firmware as a Christmas gift, as if they invented the wheel when some other folks have already been running at the same efficiency or better using custom firmware long before Christmas, the clock settings should be open by default, at least the ones that are lower than the default, in many places temps get pretty high on 20-40 days a year, gears can't run stock, it makes no sense to invest in cooling just too cool the miner for 20-40 days, also makes no sense to let it toast, a perfect solution would be to underclock it, even better, doing so on the stock firmware without having to pay dev fees.

هل يمكن ات تشرح قليلا ؟ الهجوم على باكسوس يعني الهجوم على عملة BUSD و USDP, الهجوم على تيثر مستمر منذ سنوات, وفقط لهجومهم على عملة دون اخرى ليس دليلا على شي, في حال كان الهجوم على عملة مستقرة اخرى هل كنا سنقول ان الاستهداف كان يجب ان يكون لعملة BUSD؟



الهجوم على USDT مستمر منذ سنوات, هدا لايعني انه لايمكنهم الهجوم على العملات الاخرى, اما بخصوص تجميد الارصدة في المنصات فهدا لا علاقة له بالعملات المستقرة, يمكن للدولة تجميد ارصدة المنصات حتى ان كانت بالبتكوين ان كانت المنصة خاضعة لسلطات تلك الدولة.

ايضا عندنا نقوم بربط الاحداث, في الاسبوع الماضي توقفت باينانس عن قبول طلبات الايداع والسحب بالدولار, وتحليلي الشخصي لما يحدث هوا محاولة من الحكومة الامريكية لفصل ارتباط العملات المستقرة بالبنوك باي شكل من الاشكال لان هدا الارتباط يعطيها طابع قانوني ويزيد من قيمتها كعملات مسيلة بطريقة جيدة, العملات المستقرة تستعمل الدولار كغطاء لقميتها, وعند تداولها على البلوكتشين بدون مراقبة مباشرة من الفدرالي يسبب قلق لدى الحكومة الامريكية, تخيل انه بالرغم من كل العقوبات على روسيا, اتضح ان العديد من الشركات الامريكية لازالت تتعامل مع شركات روسية بكل سهولة وكل هدا عبر البنوك النظامية, اذا مايحدث من تحويلات بالعملات المستقرة المغطاء بالدولار قد يكون كارثي بالنسبة لهم.
