1  Alternate cryptocurrencies / Mining (Altcoins) / Re: Looking for a CNV1 Asic/FPGA Mining Rig + specifications + reward for contact on: June 01, 2019, 11:10:26 PM
The general consensus is CN7 asics were only ever mined in private and never sold to the public.
Having said that, you might get lucky and find someone with some connections who can get you some.

I rarely check this thread even though I was the one that started it.

To update the general readers:

1. All people who bought VCU1525 cards right when this thread was announced, have already ROI'd their cards (mostly from mining 0xBitcoin at $15/day for 6 months before BCU's shipped, and then Microbitcoin at $20/day for a shorter period); unfortunately by the time BCU1525's shipped, other FPGA farms were online and profits were less, so no, BCU1525 have not come close to ROI, even though early VCU1525 already paid themselves back

2. I am still working hard on X16R/RT/S for BCU1525 and CVP-13, being released in the next few months

At $2 - $2.5K per BCU, personally I would buy every single one if I had money, I already bought some second hand ones (as many as I could afford).

This is not in any way a suggestion that you should get into FPGA mining.  However if you already have hardware, some pretty good bitstreams are around the corner.  Having said that, I would wait until the new bitstreams are actually available if I were you; it is always better to buy hardware that can already do what you want, rather than 'might' do what you want.  In my case it is different, I can buy 2nd hard hardware safely even before the bitstreams are available because I'm developing the bitstreams and I know they will work, but outsiders don't have that certainty and should play it safe.

Is the approximate number of BCU-1525 in the market known at this moment?

There are 5000 BCU1525 in circulation.

Right now the most profitable public bitstream is Nexus, available on zetheron.com.

Please note that all zetheron bitstreams are available to all users, you just send a video of your hardware mining 0xBitcoin and you receive the non-public bitstreams.

There may be other developers that have truly 'secret' bitstreams that are not at all available to the average Joe.  I don't know.

Microbitcoin uses diamond-groestl, not groestl.  The merkle root calculation is different than groestl.  Therefore, the sgminer firmware needs to be changed to mine it, even if the hash function is the same as groestl.

I agree ROI calculations are useless which is why I always precede with 'ROI at today's market would be...'

Currently the most profitable algorithm on BCU makes $11 per day:

CVP-13 won't cannibalize much because most CVP owners will mine RB3 which isn't available on any other card.

I will post photos of the bridgelink X1 once I have permission to.  Unlike other sketchy companies bridgelink wants their card fully tested and ready to order before being officially announced.  I helped in the design to eliminate unnecessary components and keep price as low as possible, and the result has been good.

LOL, N00bs offering group buys!

We've never seen that one before!

Quite so! If you read it again you will see that first I asked if one of these "Crowd Funding Buys" even existed, then if not I would be willing to start one. And yes, I realise that my post count is not in the thousands and that basically nobody here knows me. Didn't seem like a reason not to offer something that could open the doors of FPGA mining to a lot of people.

The way I see it, there are people here who would like to FPGA mine but either don't have thousands to invest in a card right now or think it is too risky for that kind of investment. What I propose is a lower entry point. If you are saving up to get a card, why not collaborate with others who are doing the same? So instead of money sitting under the mattress, it is actually mining and making money back.

Potentially, you could invest a couple hundred, instead of thousands, and then in a few years be able to get a dedicated card at a fraction of the price. (Re-investing any coins mined back into the system and letting them just grow there till you can get a dedicated card.) Or, you could keep adding more money as you have it till you can get a dedicated card, plus whatever coins you mined in the meantime. (Or get a dedicated card faster using the coins)

Risk: Trust a "Noob"
Reward: The ability to risk less money and still try FPGA mining or possibly to put money to work that would otherwise be sitting idle as you saved up for a card.

If you feel the need to bail after the card/s are bought, no problem! I, or we collectively will buy your shares of the card and you get your money back.

It's an interesting idea, but you could also just buy a $549 Bridgelink X1 FPGA card that has (at the moment) about 290-330 day ROI and experience FPGA mining with hardware in your hands.

Mineority couldn't make it. Sorry for anyone that signed with them.

Squirrels, FPGA.land, Zetheron will be next. They are all connected.

Anyone that hasn't got their refund for the 1525's, better hurry. They all are probably bleeding out.

Too bad the little guys can't compete with Bitmain, etc. Check out the F1 FPGA miners. Clearly looks like Bitmain.

12 algos to choose from....not waiting on 1 dude to come out with a stream at double the price for a unit.

"Clearly looks like Bitmain" - Because they're from China?

Interface looks like Bitmain. Ever owned one?

Blackminer F1 fpga miner does look and operate similar to most asic miners including Baikal and Innosilicon ones.  They all look and operate similarly for good reason, it's a form factor that works for readily available 120mm fans, and the ethernet/remote setup works well.  The blackminer guys have nothing to do with any of the asic companies.  They are nice guys and have even offered to open up their hardware for other developers, although most of the other fpga developers are far too busy at the moment.  I know several people with F1's in hand and they are all happy.  Technically I'm competing against them with my own software but the competition is friendly.

We got permission from the microbitcoin dev team to produce a public bitstream for the upcoming fork of the coin.  This fork will kick off the G28 asics and still support GPU's and FPGA's.  Good news for FPGA acceptance, and other coins are also slowly embracing them.

The new Bridgelink X1 FPGA card ($549) is showing incredible results in testing, and looks to have an ROI of about 290-330 days in the current market.

Soon the $1599 Cairnsmore5 and the $549 Bridgelink FPGA cards will be available, and no matter a person's finances they will have access to home FPGA mining.

Looking for a cheap FPGA for another project (maybe mining after), Bridgelink sounds about in the budget but I can't find any info on it? Also looking at a XC6SLX150, have you had any luck with those? How do they compare?

Bridgelink prototype is currently operational, more details coming soon.

As one of the main developers for FPGA's, I can say that no current FPGA's have yet been programmed with Timetravel10, and the sudden drastic increase in net hash is caused by Baikal G28's.  The Baikal X10 was unable to change the order of hash algorithms but their updated Baikal-X did have that capacity, and the G28 is just two overclocked Baikal-X.

The appearance of Baikal ASIC's on the bitcore network would be okay if this algorithm was publicly available for owners of Baikal-X or Baikal G28, but it is being held privately by Baikal mining.  In my opinion at this point it would be trivial for them to take 51% of the hash power.

I have been a huge fan of Bitcore since 2017, and mined it extensively with my GPU's.

My suggestion is that coin devs switch algorithms, I know hard forks are a huge pain, but the coin safety is in jeopardy.

In terms of which algorithm would be the best to switch to, I have a lot of input on that topic just as I have given many suggestions to the microbitcoin team; the algorithm of choice depends on what type of hardware you want on your network.  The problem with GPU friendly algorithms is that GPU mining is so unprofitable that most GPU mining is now done in big farms with low electrical costs.  Generally I recommend algorithms that support GPU's and FPGA's at similar ROI, and in some cases you can even (almost) equalize ROI on GPU/FPGA/ASIC like with the pure Gost algorithm.

Yes, but you can already see a looming problem: developers are always going to be tempted to go with the newest/fastest card when rolling out new bitstreams.  I am still waiting for my BCU-1525 and I am reading about the CVP-13, which may ship right after I finally get my BCU-1525.  I don't see developers working very hard on last year's model of FPGA to add new bitstreams.  I'm taking what is posted on the Zetheron site more or less at face value, i.e., you can't easily port your bitstreams between models and different brands.
[/quote]

Technically the most attractive FPGA to develop for is the one in biggest circulation which is BCU1525.  However, if an algorithm 'fits' into a different FPGA's of the same brand (xilinx or intel) it is actually quite easy to port over.  RB1 only took about 3 days to port from BCU1525 to CVP-13.  In some cases bitstreams can be ported from one card to another in a few hours.  Porting 0xBTC to the low cost cards only takes a day or two each.  The bigger problem is porting from Xilinx to Intel or vice-versa. 





12  Alternate cryptocurrencies / Mining (Altcoins) / Re: DIY FPGA Mining rig for any algorithm with fast ROI on: November 25, 2018, 03:06:02 AM
I will be porting my code to the Bridgelink FPGA and the Cairnsmore5.  However, be warned that the lower-cost FPGA's have some pros and cons:
PRO -- the low cost FPGA's can sometimes mine core-heavy algorithms at better ROI than the high end cards
CON -- the low cost FPGA's can't mine memory intensive algorithms (no equihash variants or cryptonight variants)

Right now in terms of availability
CVP-13 $6000 available now
Krunchlabs MA-X1 $3650 available Dec 10
TUL BTU9P $3599 available now

Full list:
http://zetheron.com/index.php/supported-hardware/

The current dip in the market is pushing more GPU's offline and GPU farms out of business, resulting in global drop in nethash.  This will eventually be good for FPGA's especially when the market rises.

The latest profit table was update a few days ago:
http://zetheron.com/index.php/fpga-performance-profit/

Keep in mind also that several big coins are seriously considering new algorithms specifically designed for FPGA's.  These would likely run very well even on the low cost cards.

In case people haven't already realized it, I am not doing this for the money anyway.  My RB1 bitstream was released with no dev fee and people volunteer to send in their 4%.  In many cases in the last 8 months I turned down huge financial offers from private farms that wanted private bitstreams, but I am trying to help crypto stay in the hands of home miners.  So, even if it were true that releasing stuff publicly wasn't the best financial choice, finances have little to do with it.  Idealism does.  And I think I speak for the other groups as well; you can bet that up until now, Squirrels, Allmine, Mineority and Zetheron have all operated at a loss trying to get FPGA's into the hands of home miners.





15  Alternate cryptocurrencies / Mining (Altcoins) / Re: Ravencoin mining software development? on: November 21, 2018, 04:57:33 AM
Any attempt to produce an X16R miner from white papers and first principles will fail 100%.  If you are new to mining algorithms you must realize that every mining algorithm has within it a tremendous amount of tribal knowledge.  Various bit widths, round constants, parameters, conventions, endianness, all changed or modified from original algorithm specifications without documentation of any kind.  Mining algorithms have been developed and tweaked from earlier code, which was itself tweaked from earlier code, and so on.  SHA-3 refers to a specific and final Keccak variant after several revisions by the original development team.  No crypto algorithm actually uses SHA-3, they use what they call 'Keccak' which is an earlier version of that specification, and different crypto algorithms use different variants of Keccak based on different papers published on different dates.  There is simply no hope to make a working miner without starting with existing open source code that works.

You still need water cooling radiator/hoses/pump, I recommend Koolance products.

Please excuse me if this is the wrong thread to ask this question, but has anyone received their BCUs purchased somewhere at the end of June 2018?

I paid for 2 pcs, one for me and another for my friend, but now I don't see any of these FPGAs under my account at Mineority.io. The support guys do see it somewhere at their end, but here I am without BTC and without FPGAs...

Go into the discord and ask in the Mineority channel, you will get an answer within an hour or so.  Not all FPGA's have been shipped and I don't think any of the water cooled ones have been shipped.

The first private Zetheron bitstream for the VU9P FPGA series has now been released.

What algorithm?



It's private, hence the algorithm is not made public.  This is to prevent coins from forking.

My customers have posted their profits in the discord, most are reporting $17-$20/day per card.



The algo he is referring to is 100% lyra2z. The majority of the coins they are targeting are aware and forking. Hence his customers might need to ask for a new bitstream

?
Lyra2z was released by Allmine and most BCU1525 owners are mining with it.  That is not secret knowledge, everyone knows.
There would be no point for me to release an algorithm that is already done by someone else.
I have no plan or desire to target Lyra2z.

The first private Zetheron bitstream for the VU9P FPGA series has now been released to a select group of about 50 miners.  This bitstream is currently making over $20 per day for FPGA and up to $26 per day on good days.  It was hacked together in just 5 days to take advantage of a coin/market opportunity and is currently rather annoying to run in terms of a complicated start up procedure.  I am working on a cleaner version with live voltage control and variable clock speed, it might be offered for sale if the coins are still profitable in a couple of weeks.

I will also build a CVP-13 version which makes 50% more than the VCU1525/BCU1525 version.

This algorithm can only support around 350 BCU1525 FPGA's.  I have another algorithm in progress which can support about 3000 cards at $15/day, it should be available within 3-4 weeks.  It is not yet decided if it will be a public or private launch.  Even private launches are available to anyone who has hardware, the reason is to try to prevent coins from forking.  FPGA's can still follow the fork but it is big time waster.
