1  Alternate cryptocurrencies / Announcements (Altcoins) / Re: 📱[ANN][ZCore - Official Release] [🔥UPDATE🔥][ PoW ] [ Lyra2z ] [ CPU/GPU ] on: November 28, 2018, 01:08:14 PM
Would there be any good reason that my wallet show me 4.69 zcr and only 4 transactions, while on the pool i mined 17 zcr and the pool shows around 16 transactions to my wallet ?

im using score-qt on linux. looks like synced with network, tried a rescan of blockchain without any success.
Looks like 13zcc are in the wild but not in my wallet.

Score-Qt or ZCore-qt?

Score is an different coin.

Solved my issue, went on discord, got support.

Of course i was talking about zcore-qt, typo at hand in this case.

So, after almost 2 weeks since keccak bitstream release, does anyone succeed to mine keccak with whitefire's work and Xilinx card ?

Any physical evidences that this is possible, working as expected ?

Well time to learn linux i guess. For all those windows beggars.

Is it still possible to enter the first batch or from your website everything is sold out ?

Attention, je pense qu'il y a confusion entre un FPGA et un ASIC.

Il n'existe pas 100 000 fondeurs de circuit dans le monde, et ils sont tous asiatiques.

Voir apparaitre des prototypes, fait a quelques exemplaires, pourquoi pas. Graver industriellement en 14nano voir 7 nano c'est une technologie qui est tres restreinte et je ne pense pas que cela existe en France ou en Europe. (prouvez moi le contraire).

Le plus interressant dans le FPGA, ce n'est pas le hardware, qui est dans les mains de quelques concepteurs et fondeurs, mais l'aspect logiciel. Oui j'imagine qu'il y a de tres bons programmeurs de FPGA en Europe et en France. Les FPGA sont utilisés dans l'industrie militaire et la haute finance en particulier. Deux domaines de pointes, ou les programmeurs sont grasscement payés pour bien faire leurs boulots.

Et oui il semblerait que Bitmain soit en mesure de faire pression sur les fondeurs chinois. Tel que rapporté par plusieurs entrepreneurs qui voulaient faire fabriquer des ASIC en Chine et qui se sont vu fermer les portes au cours de leurs projets.

J'ai lu un article dernierement qui justement illustrait la pression que Bitmain exerce sur les fondeurs chinois pour empecher toute emergence d'une concurrence.
Ce qui induit que la fabrication d'ASIC en dehors de Chine etant plus couteux, les chances que des ASICS soient produits en dehors de Chine est tres faible.

Effectivement, il est sage d'attendre un peu.

Cependant, un gpu, c'est un peu comme un asic. Des puces dédiées de traitement sur des nombres. Malheureusement ce ne sont pas des puces dédiées a du calcul de hash ce qui explique que le mining gpu soit moins éfficace qu'avec des asics dédiés.

Concernant les fpga, se sont des circuits electroniques qui ont la particularité d'etre programmés pour "simuler" un circuit électronique. Ce sont des matrices de "portes" dont la logique de connexion est programmable par un langage descriptif. En teneur, verilog ou vhdl sont des langages qui decrivent formellement la logique booleene d'un circuit electronique, et le bitstream (sorte de firmware) va implémenter cette logique dans cette matrice de porte.
Les FPGA servent au prototypage et a la conception de circuits electronique comme des asics sans en atteindre la performance. Cependant, le fait que le FPGA "simule" un circuit electronique fait que ses performances vont être supérieures a celui d'un CPU ou GPU qui sont beaucoup plus généralistes.
Par exemple, sur un cpu l'execution d'une instruction se decompose en plusieurs étapes, car le CPU est obligé de comprendre la tache qu'on lui demande (programme). Un FPGA une fois programmé ne comprend que le signal electrique et n'a pas d'intelligence embarquée.

Ce qui va différencier un FPGA d'un autre, c'est en particulier la taille de sa matrice de porte. Plus la taille est importante plus il peut simuler de gros circuits.
Ensuite la mémoire interne a disposition va aussi faire une différence sur la complexité des calculs. Ensuite ses entrées/sorties et son horloge interne qui vont lui servir a s'interfacer avec le monde exterieur et conditionner la frequence d'execution.

Le principale interet du FPGA est le fait qu'il est programmable. Donc il peut sans soucis s'adapter aux changements d'algorithme de POW, contrairement aux ASICs qui eux deviennent obseletes en tel cas. L'autre avantage est que le ratio hash/w est plus grand que sur cpu/gpu. On peut lire si et la sur cnv7 du 65kh/s pour 300w, 65kh c'est environ 30 rx vega 64, soit 30*200w de conso electrique. Le principale interet est là : consommer moins pour calculer plus.

Cependant le gros point noir du FPGA: la rareté des developpeurs. C'est une minuscule niche dans l'industrie. Et les bons developpeurs se comptent sur les doigts d'une main. Il faudra faire confiance a un petit nombre de developpeurs pour sortir des nouveaux algo a miner.
Et si tu comptes devenir developpeur, la courbe d'apprentissage est tres ardue. Donc ne pas s'attendre a sortir un truc convenable avec 1 ou 2 ans de travail acharné, en commencant de rien.

Wonder what this means for bittwares fpga mining offerings....

https://www.molex.com/molex/news/new_display_news.jsp?channel=New&channelId=-8&oid=2376&pageTitle=Molex+Announces+Acquisition+of+BittWare

Code:
Molex Announces Acquisition of BittWare

That is certainly interesting. In my experience such acquisitions usually kill little projects like this, but I would be happy to be surprised.

I more prone to think this crypto mining announcement was more oriented to inflate company value with more expected sells revenue ! a good move to move to make buyer thinks his investment has some good potential of profit.

Due diligence on company financials, product pipeline, customer base, etc would have been completed long before the start of this thread. Molex would be looking at proven sales/revenue streams for BittWare. That comes from industrial customers and not crypto.

Well, OP started to talk about fpga and mining in january. This thread is just the result of increased interested of reader from others threads.
I understand your point, i dont mean mining market was crucial in this transaction, but it can add a little sugar in the process.

45% -- Would have been lower but I lost a LOT in Jan 2018 when shitsmartcash got hacked

Oh yes, that was me. I was controlling the market as much as I could. Most FPGA i ever had at a single time was around 800.


Well, I am jealous and I knew something was up when the prices kept climbing.  Wink

Don't be, I wasted all my profits flying all over the world trying to raise $5M to build out a huge FPGA mine. All the investors thought it was too good to be true and did not believe that I was mining on AWS. They kept saying "why isn't anyone else doing this", "I love the idea! come see me!", "I want to introduce you to my friend! They're ready to invest! You just need to go see them!".  Roll Eyes -- Hey, at least I got to see india, china, hong kong, switzerland, germany, france Cheesy. Definitely never going to fly anywhere to meet an investor again though.

I contacted Bittware and they are delaying the release of the crypto version of the XUPP3R.
Looks like I may have missed out.

Sorry, I've been meaning to make a post related to this.  We have been working with the OP to determine the optimal configuration and board for this application, as we have a few to choose from.  The XUPP3R may not be the optimal one, we have other boards, including one with larger core power supplies and even the VU13P instead of the VU9P.  The OP is working to determine the combination of FPGA size, clocks, logic, memory and power use that maximizes ROI.  We do not want to sell you boards that may not be the best fit, that is in no one's best interest.

So you have not missed out, you perhaps have saved yourself from buying a non-optimal board (we actually have not yet taken any orders or shipped any boards to miners so no one is in that camp).  You can still contact us and we will get back to you as soon as we have enough details to let you place an order.

Interesting, so on what hardware OP was first developping ? I mean, in the first post, there is two devices listed. I hope OP didn't push your board without some effective experiments.
This delay and those explanations are quite suspicious. Either OP has working bitsream with real number on the VU9p, either he has nothing today.

My opinion is that you are quite surprised by the community huge demand, and you don't know how to face it, also in regards with your regular customers who are going to push price down once you sell similar card cheaper to miner. lack of preparation and fear of unknown Smiley

...
the lack of developers in this arena and the lesser utility/other uses of FPGA (in general population) makes me think twice in investing more in this kind of stuff...unless i knew a guy in person that i can work with, not just some random guy in the internet..

As far as im not leaving on american continent, i called my local Bittware reseller several time last week. He is well introduced into this FPGA field, selling and developping on those kind of board and technology since more than 10 years.
Therefore, he has knowledge and skills, also has in his professionnal network some independant developpers with more skills and knowledge in this area. He already inform them of the existence of this thread and waiting their feedback.
Local reseller are valuable consellor.

whitefire990: really nice job in identifying & executing on this opportunity with FPGAs! I still have a bunch of Spartan6 LX150 FPGA hardware (from 2012, when FPGA-mining Bitcoin was a thing!) but I doubt this type of FPGA can be as profitable as your cards.

Do you have a particular process for identifying which PoW algos are the most profitable on FPGAs? For example you implemented Phi1612... it is not even implemented by tpruvot's cpuminer. It's used by LUXCoin which is a rather obscure coin (#458 on https://coinmarketcap.com). Did you manually examine hundreds of PoW algorithms to find the best opportunities?

If you have a Zetex 1.15y with four Spartan LX150, a tiny modification to the code will change it from SHA-256 to SHA-224 and it is quite profitable mining Bismuth.  Coinosaurus pool can give you the JSON protocol to submit shares since Bismuth pools don't use stratum.

Regarding the algorithms I spent months analyzing every single one to determine which were most suitable to FPGA's.  I checked them all.


So is cryptonight and all its variant already studied and planned for release ? I think we are a bunch o people looking for real numbers about monero mining and fpga.
Thanks in advance

Note that we do have onboard monitoring for temperature, voltage, and current, with thresholds set to shut down the board if it appears to be entering a situation that would cause damage.  We provide a utility (console and GUI versions) that you can use to talk to this onboard controller via the USB and see what is going on with all the sensors.  Unlike GPUs and CPUs, FPGAs have no inherent thermal throttling, unless the FPGA developer builds that into their logic, which is very rarely done.  FPGAs also burn more power as they get hotter, so from a power efficiency point of view, it is better to keep them cool.


@BittWareFPGATech

The OP stated that you will be mining with your own boards. Can you vouch for these hash rates presented by the OP?


We have not yet done any mining, and for the record, have no big plans for this.  We have joked internally that perhaps we should use mining as the factory burn in test for our boards.  The OP has offered to get us the code once released, and we may play around a little to understand the thermals, etc.

yeah, unlike ASIC miner, i would not like to receive a second hand board, that already spend few weeks/months mining in your secret basement.
20  Alternate cryptocurrencies / Mining (Altcoins) / Re: DIY FPGA Mining rig for any algorithm with fast ROI on: May 04, 2018, 08:58:41 AM

I am saying it makes no financial sense. The major GPU coins already have asics, with ETH being the biggest. And those coins that have no asic on it will have asics on it before the FPGA will come close to ever breaking even.


And everytime an asic takes over an alternate coin, all the GPUs and FPGAs that were mining that coin will go to a non-asic coin. That means the remaining non-asic coins will have difficulty skyrocket and guess wat, that means your GPUs and FPGAs mining make less money. Everytime a new asic comes out, the FPGAs make less money. So, there is no niche. There is a limited amount to be earned from mining u see. If the asics keep appearing to take some of it, the switchers (FPGAs/GPUs) will have less and less.


Why not u calculate how much it would cost to make an FPGA that can do the equivalent of mining 504mh like the L3+ or 14TH like the S9.
Run your numbers and see the gap. While I dont have the numbers, I dont think it can work.

Anyways, good luck in your endeavors. Maybe I am wrong.


Just my 2 cents

While your point of view is true in general, there are a couple of exceptions: mainly space and power constraints. Let’s be very specific in our comparison to avoid meaningless comparisons, XCVU9P ($4,000 FPGA) vs GTX 1080 Ti ($800 GPU).

Now let’s take the Phi1612 algorithm and give the FPGA a more realistic 5x performance advantage against the GPU at a power consumption rate of 150 watts (0.150 kWh). I would rather run a 100 FPGA farm (17.5 kWh) vs a 500 GPU farm (87.5 kWh) any day and here’s why. Lower overall costs if you believe the 5x advantage ascribed to the FPGA.

4x FPGAs and components approx. ($16K + $1.2K) in server chassis and add 100 watts for overhead.
4x GPUs and components approx. ($3.2K + $0.65K) in frame and add 100 watts for overhead.

$430K 100 FPGA farm vs $481.25K 500 GPU farm. Can you at least agree that this makes financial sense?

No that makes no sense. 481.25k/430k = 12% better only LOL.

---------------------
Rough Comparison:
----------------------
And while the E3 does 180mh for 800watts which is comparable to some GPUs, bitmain can sell it for as little as 800 USD if they want to. Thats the price they sold on first batch. To do 180mh, u will need to spend about 2500 on a rig. The asic can be 3 times cheaper

For 300watts, u can get 10,000 sol on asic or for gpu, u get say 1,100 sol? Thats 9 times more efficient and the asic is also far cheaper on a per sol basis.

If u consider the gap between using gpu to mine bitcoin/litecoin, vs asics, the gap is even bigger.
Doing it 12% beter on FPGA isnt a game-changer at all.

---------------------
Why FPGA cant win
-----------------------

There is a limited amount of money that can be made from mining.
Lets say, for illustration, there are 100k of coins released for miners to earn every 10 mins

In the past, 10% of all coins are mined by ASICS and 90% by GPUs or FPGAs (aka switchers)
Time passes and asics mine 30% and then 50% and then 70% of all total mined coins.

Thus, as  time pass, the switchers (GPUs and FPGAs), now mine only the remaining 70% and then 50% and now 30% of coins.
Hence, as time passes, there will be more and more switchers sharing a smaller and smaller percentage of the mining PIE. The switchers mining profits will just decrease and decrease as the total % of all coins they mine decrease


And if a new major coin appears, the FPGA wont mine it long before an asic takes over. The remaining switchers will be sharing a smaller and smaller pool of coins. Thus, they will earn less and less as the remaining pool of coins have their difficulties skyrocket
Thus, u gotta be abit mad to think u should invest in more expensive equipment just for that.

--------------------
Speed of Asics being developed
---------------------

I mean just look at this year. It is only early May and we have a decred, sia, eth, cryptonight and now zcash asic. Thats 5 major algo and at least 5 major coins being taken down by asics. It is like one new algo takes down one major coin a month. Furthermore there might be other asics algo already made, just not released yet. And lets face it, a new major alt coin appears, it will be taken down by asics soon.


-------------------
Difficulty wave coming
-------------------

Ok, so in June 2018, the E3s will be shipped. ETH difficulty will skyrocket and alot of GPUs will move from ETH to other coins. Expect other coins difficulty to increase. The good news is that E3 price was increased from 800 to 2,100 usd. This means slighty lesser E3 purchased and lesser difficulty increase compared to if it were 800 USD. Do note that E3 price may go down again in future down which leads to more E3 purchases and higher difficulty. The antminer L3+ went down in price and wat occured was a massive litecoin difficulty increase. If the E3 goes down in price, it is gonna take down GPU/FPGA mining even more. Remember, it can be priced 3 times lower than a gpu rig and a far stronger E3 may appear as well. U are pretty much at the whim of bitmain here. ETH is actually the major gpu coin. E3 price down to 800 USD and goodbye to all gpu because all gpu will move to other coins and all other coins difficulty will skyrocket. This will probably occur eventually.

The Z9 mini will take down zec/btc-gold gpu mining, period. SIA and Decred are asic owned.

Thus, I just dont see how it will work. By right, it was over for gpu when E3 appeared since eth is the major gpu coin. Does anyone know how much % of GPU mining is ETH. Is it over 50%?

Asics have clearly won the war. They may very well push GPUs to have 5-10% of total coins being mined in future.
I believe u are letting your feelings cloud your judgement. Anyways, good luck to u buddy.



Just my 2 cents

Your 2 cents are quite interesting but miss the point.
What does ASIC resistance is ?
Basically, choosing hashing algorithm for which developping ASIC cost a lot and therefore renders mass production unattractive.
This was the main point of Cryptonight in 2013/2014, choosing high memory intensive algorithm, to put a physical economical barrier to ASIC developpment (back in the time memory integration on ASIC was very expensive).
Given technological progress, in 2017, it seems memory unit are more affordable for ASIC, and we see ASIC of Cryptonight publicly released in ferbruary 2018, and we suspect them to be already mining since july 2017.
The major pitfall of ASIC is staticness. Which means that the work it is designed for cannot be updated or changed after. So the new strategy for beeing asic resistant, if to often change POW algorithm. It's a cat and mouse game.
So when coin dev choose to change their pow algorithm, like Monero dev did, those expensive and efficient piece of hardware are becoming useless except for blocking door (or targeting minor CN coins for less profit).

Some other coin dev choose to not change their pow like BTC did not after ASIC appearance. Like zcash seems to choose also.
In that case, it is clearly obvious that ASIC will soonner or later dominate the mining of those coins, any other kind of hardware are far less efficient and more energy consumming.

So where is the market for FPGA mining: Basicaly all coins which developpers want to keep ASIC mining away. Most of cryptonight variant for instance, Even if monero change pow every 6 months, every 6 months developpers can release updated fpga file to adapt to new pow.
Also all coin which are not attractive enough to invest huge money into ASIC developpment based on exotic POW which can fit nicely in FPGA. Bringing better h/w ratio than gpu/cpu mining. Of course when an ASIC is existing for a coin, and developper dont want to hardfork POW, there is no more room for cpu/gpu/fpga mining.
