Bitcoin Forum

The reason for creating this thread, is to keep everything in one single spot.
All the info is out there, but it's all over the place, making it difficult to track.
I will be updating/editing this page, as we go along from the c29 to the c31 algorithm, and until ASIC's are fully implemented during the next two years.

Current block rewards are set to 90% for c29, and 10% for c31.
Any corrections, additions or suggestions are very very welcome. ;D

this was my experience with Grin.

all over the place, half baked and no real focus on it's correct processes.
however. i do think there will be great success with Grin, it will just take a bit of hard work on the developers parts.

good luck.

GRIN...what a fucking stupid name for a shitcoin.

 ::)

Just to be clear. I'm not a developer, nor have any connection to Grin Dev team, or any team for that matter.
I'm just an active miner.

#


I'm sure they will appreciate your feedback..
Not all alt coins are shit coins, but I feel ya. This one has potential imho, if the team can follow through.

Added: https://coinalyze.net/grin-live-price-charts/

Currently - bench marking between the two algorithms, c29 & c31 seem to have roughly equal rewards. Marginally, c31 is ahead.

Hardware used: 1080ti's & Vega64's, both running on Minerbabe.

You should probably split GrinPro and GrinGoldMiner in your miner list.  While it's the same author, GrinPro is newer, closed source, and has much better performance (at least on some cards like RX580s).

Also, this is prob useful - I've been updating w/ my stats, would be good for others to do the same:

https://github.com/mimblewimble/docs/wiki/GPU-Mining-Stats (https://github.com/mimblewimble/docs/wiki/GPU-Mining-Stats)

Also this:  https://grinscan.net/charts (https://grinscan.net/charts)

And it's probably best if you don't 'recommend' the top two pools accounting for 80+% of nethash.  H/r needs to get distributed...

Not sure how that works out... I get 3.4 for c29 (GrinPro on Windows), and .43 for c31 (kbminer/minerbabe on Ubuntu) on a Vega64 @ ~165W.  Plug those into the calculator you have posted you'll see that rewards for c31 are double c29.

Edit: more like +70% currently, after this recent c31 spike.

i like this project sir..do you have bounty program..I am sure that if there is a campaign program, there must be many participants

Because GrinPro and GoldMiner as you mentioned, are from the same author, both versions are listed to avoid confusion.
The stats are nice, added, thanks.

#


There seems to be a race between them on a daily basis so far.
The calculator is off a little, but if you use the other ones as well - it gives you a rough estimate.
That said, my best indicator so far has been the home page of sparkpool.
Their calculators give more precise results.

Looks like that today, c29 is gaining ground.

#


I like it too Sir. It is not my project of course, I'm only supporting it.
Feel free to support it yourself:
https://grin-tech.org/yeastplume

Added also.

Sure, it is worth considering. But the bottom line is where things work best.

Grin experiment was a lot of fun. I've learned many things from it. But for now, it is time to move on to the next one. Mining Grin isn't really profitable anymore unless you sell right away. Hold for a few weeks/months and inflation will take a big cut of your profits. I'm currently mining Grimble: https://bitcointalk.org/index.php?topic=5104584.0 the first Grin fork with adjusted monetary policy.. Difficulty is catching up quick now, but not near as high as Grin fortunately  ;D

How is grimble 'profitable' when you cant even sell it?  More like a gamble

You can sell OTC, like a lot of people do? I've seen a few buy and sell orders pop up already.

Also, it's been less than a day... exchanges will probably come soon.

I wouldn't bet on it. :P

Grimble is a fucking scam.
And these two are fake. Just like their coin.

Yeah, I'm not really baggin on it - just sayin that it seems ironic to justify moving to grimble by saying that grin is no longer profitable...

Exactly. Because currently Grin is profitable.

c29 still gaining ground against c31. Leveling out.
Thinking of switching back to c29, to have actual results.

Added NBMiner for supporting c29, & improving 2080ti optimization.
https://bitcointalk.org/index.php?topic=5099379.0

Added luxor pool calculator.
http://grin.luxor.tech/statistics

c 32 on luxor?

Yet, I suppose. ::)

c29 is currently more profitable than c31. Switched both rigs to c29.

New GMiner (v1.28), has almost reached the speed of bminer v14.1 for NVDIA (applies for 1070-2080, for 2080ti's NBMiner is faster).
Also GMiner is the first miner to support Nicehash. ;)

Yeah I dont know what this guy is getting at.  Even with crazy expensive electric it's still profitable.  All the power to the people who switch off grin mining  :D

nice work here, went to read some of https://github.com/mimblewimble/grin/blob/master/doc/pow/pow.md

guys, you are using cuckoo cycle algo and what is the difference, any source of cuckAroo29??

c29 is implemented for GPU's.
c31 is for ASIC's.
ASIC's are not out yet, so in the mean time you can mine both.
Not sure what 'source' you're asking for. :-\

continuation of hashrates discussion from Grin Observer thread here:
https://bitcointalk.org/index.php?topic=5102334.msg49585638#msg49585638



which is low? pool or bminer?

ubuntu rig has ubuntu 18.04LTS, nvidia  417.xx driver (i believe will check later), CUDA 10, bminer 14.1, celeron 1840, Z97X mobo, 8gb ram 120 gb ssd. using iGPU for display, the 10880ti is the only videocard. no real cpu load, it runs fpga miner and grin wallet/node code occasionally with no seeming impact on hashrate.

card is gigabyte aorus 1080ti, running stock.
https://www.newegg.com/Product/Product.aspx?Item=N82E16814125954

EDIT: just remembered i have both the iGPU and the 1080ti outputting the desktop in mirrored mode to my KVM, the desktop was messed up with either alone. musta done something stupid to X when i was installing the nvidia driver (i just moved the 1080ti to this rig a couple weeks ago).

Pool.
You get 7.1 G/s on bminer with your 1080ti, which as it's supposed to be ATM.
On the other hand, the pool reports a lower graph rate (5.6 G/s~20% less), which impacts your shares and your profits imo.
For sparkpool is the other way round.
My X4 1080ti's report 28.4 on bminer (same as yours), whereas on the pool side I have an average of ~26 G/s.
Also they fluctuate up to 34 G/s (pool side again). In any case that makes it 6.5 G/s on average instead of your 5.6 G/s.

I cannot post proof of this ATM, cause I had a few power cuts today and it's all messed up. Tomorrow.

checked just now. on grinmint

3 card/win10 rig reports
pool 12.3
bminer 14.3

ubuntu 1080ti
pool 6.7
bminer 7.0

my pool reported average hashrate wanders between 18 and 21 g/s vs the more or less steady 21 g/s reported by the two miner instances.

but ive read bminer reports are a bit optimistic.

ill update in the morning.

Keen on your results after a full day or so.

Almost back where it should be:
https://i.imgur.com/24OftEO.png
4 X 1080ti, Windows, c29, sparkpool, Gminer v1.3.

Looks like c31 is gaining ground today.
Gminer v1.31, now supports c31 with a graph speed improvement (1080ti~0.7G/s).
Added to recommended.

The difference between c29 & c31 has never been more leveled out till today.
Taking into account that it's roughly 10/1 the graph rate factor for c29/c31, we have:

https://i.imgur.com/0HjyQ2M.png

Other calculators also confirm this.
ATM, it makes no difference if you are mining c29 or c31.

New Bminer (v.14.2) also out today, supporting c31 with improved speeds also ~0.90 G/s on 1080ti.
I think I will give it go with this one. ;D

I would like to ask regarding the GPU mining, what type of video card do you use for mining?

The best GPU at the moment for mining is NVDIA 2080ti.
If that's too pricey for you, next in order is 1080ti. Plain 2080 is really not worth it.
The key word is 'ti'. ;)

Is this profitable or just a shitcoin of the future?

Both. ;D

I don't know how to help you if it's not your page file dude.
I have seen the error before, related to that in most cases.

I'll have a look around. ;)

did bminer support 2080Ti for C31 ?

If your 1080ti is working fine, but not the 2080ti one, then probably it's the miner's fault - as you mentioned - the solver.
I would take it to their thread.

got my 1080ti running under ubuntu on c31 using bminer 14.2.0 at grinmint. about 0.93 H/s

after maybe 15 mins its at 2 accepted, 4 rejected shares

sure its experimental c31 support but looks like more experimentation is in order.

EDIT went to 2 accepted, 6 rejected then bminer proclaimed "too many rejects" and restarted. then a bit later  i saw "no shares in 900 seconds" or something similar. and another restart.

EDIT 2 used ctrl-c to exit miner term session and the whole rig locked up.

think ill pass on bminer 14.4.0 c31 on grinmint for now

Nothing much new to report unfortunatelly.

c29 & c31 have roughly the same performance/rewards ATM.
Haven't had time to try the new Bminer on c31 yet, but I gather it's kind of buggy, so maybe another reason for taking this slow.

Grin listed on Bittrex today, added to exchanges.

10x1070s I already have and 4 recently purchased 2080Ti.  ;D

Have tried in the past couple of days things with Bminer up to v14.3.1 on windows 10.
Have not succeed on getting it to run c31, despite upgrading to CUDA 10 and the latest NVDIA driver (418.81).
On c29 it runs OK-ish, without achieving the named speed (6.6 G/s instead of 7.1 G/s).

On the other hand GMiner v1.3.1 runs fine on both c29 & c31 - even with CUDA 9.
I get a solid 7.1 G/s per ti on c29, & 0.66 G/s for c31. Those are the best speeds I've seen so far for c29, c31 and windows.

It appears that Linux miners will always come first.

Grin added on Poloniex.

Gminer 1.3.2 is released, but has a fidelity bug - reporting low graph rate on the pool side.
Use of 1.3.1 for Grin is advised, until the new release.
Still not working for AMD.

Did you confirm your hashrate poolside? I ran Gminer 1.3.1 for 24 hours on a 2070 and it showed 6.2-6.3 the whole time on the miner, but my 24hr pool hashrate was 5.6 for that period. Then I tried it on Bminer 14.3.1 and it showed 5.7 on the miner, but 6.1 at the pool. Both tests were ~24 hour periods, so it seems like its a legit result. Also, this matches what I observed a couple weeks ago when comparing Bminer vs Gminer using 1080s and 1080Ti's - the pool hashrate always was lower than Gminer reported, while the pool hashrate was always higher than what Bminer reported. I've read some others who said the same thing. All my testing was using Windows 10 and at Luxor for the 2070, but F2pool for the 1080s and 1080Ti's.

https://i.imgur.com/gGLuO6M.png

Running on sparkpool, with a nice average, using GMiner 1.3.1 on 4 X 1080ti's mining c29.
That would make it 6.5 G/s+ AVERAGE per ti. Reward wise as expected.
It could be your pool. You should try another one.

Firstly, I made a mistake in my prior post. I intended to say Bminer showed 6.0 gps (not 5.6gps), but poolside, I got 6.1 gps. You mentioned in your prior post that you were getting a solid 7.1 gps per card, but this post shows you're getting 6.5 gps poolside - that was my whole point. Gminer shows significantly higher hashrates than the pool, while other miners do not and/or it is less pronounced.


Rather than spewing numbers about, I'd encourage you to continue testing. I've tested Luxor, F2pool, sparkpool, and Grinmint using Minerbabe's Kbminer, Bminer, Gminer, and Grinminer on Linux (mostly SMOS) plus Bminer, Gminer, and Grinpro on Windows 10. I've done some with a P106 x6 rig + 2 1080s, 2 1080 Ti's, a 2070, and a 2080 Ti in various configurations. (Side note: Every time I add 20xx cards to a rig with 10xx cards on SMOS, one 10xx card fan will stop working correctly, so I have to separate them). I'm located in the southeast US, and in every test I've conducted, Luxor has shown lower rejects and higher reported hashrates than F2pool, sparkpool, on grinmint (in that order). Additionally, Gminer has always shown a higher hashrate than reported poolside, and Bminer has always shown a lower or equal hashrate to that reported poolside.

If you are only going to use Windows, I've found that, for my circumstances on the pools I've tried and the cards I have, Bminer 14.0+ shows better results than Gminer 1.31.

OK. Bminer (v14 or v15) poorly supports cuckoo. It is very unstable. The difference in G/s compared to Gminer (v1.3.1) is minimal. Pool side. It's a fidelity thing.
And I don't just spew numbers out. A couple of posts back I meant (7.1 solid) miner side sure, but a few posts further back you can check exactly what you asked, and I answered for the second time. Only for you 'correct me' a third time round.

Instead of blaming others maybe you should read more.
Or maybe you should actually just contribute.

PS: Luxor is not advised as far as I'm concerned. Maybe it has a nice response where you live, but it's short of dodgy. It's the only pool I have lost coins in the past.

This took a wrong turn. I apologize because my bolded point (above) came across wrong. My intent was that instead of ME spewing numbers about, I'd just encourage you to test on your own - we may have different results based on where we live or our equipment, etc. I'm not blaming anyone for anything. I simply have observed different results than yours, those results have been consistent over several different versions of different miners, and those results match up with what others I've talked to have reported. Those results are that: 1) Bminer is significantly faster than Gminer on the poolside (especially, but not limited to C31); and 2) Gminer's reported hashrate is consistently higher than the pool reports, while Bminer's is the opposite. I've found this true on multiple pools, so I don't think its just an issue with the pool.

Having said all of that, I've found Bminer's latest version to be less stable and not underreporting hashrate compared to the pool for C29. For C31, it's rocking along on SMOS. Right now, I'm mostly mining C31 and get 1.91gps on my 2080Ti (0/0/225W), 1.3gps on each 1080Ti(0/0/225W), 0.87gps on each 1080(0/0/150W). I also get about 18.1gps using v 14.3.1 on my P106 x6(200/1500/80W) rig on C29.

I'm sorry too man, writing in a manner of speech can be very confusing.
Thank you for your followup.

Also testing Bminer v15 on c31 as we speak, getting a ~1.3 per 1080ti - miner side.
Looking out for bad share rate & stability - will know for sure tomorrow.
From the little I tried it on c29, seems like nothing much has changed - still prefer GMiner v1.3.1 over Bminer v15 (or 14) for c29.

Alright, Bminer v15 on c31 gives 10%-15% invalid shares. That's a lot.
Regardless it's probably still worth it compared to GMiner (everything factored in).
Personally I just don't like unstable miners, so I will switch back to c29 & GMiner.

That said, looks like c29 is currently slightly more profitable than c31.

With the new Bminer v15 reaching ~1.3 G/s on c31, turns out that it's definitely more profitable mining c29 ATM.

On second thoughts maybe not. Depends on the rejected shares rate (Bminer).
Will know for sure tomorrow, unless someone else can confirm it.

New NBminer v20 is out, looking good for c31, achieving roughly Bminer v15 speeds.
So far zero rejected shares - small sample of course.
Interesting to see how this pans out.

I've been running Bminer v15.0 for a few days now. Some users were reporting stability issues, and I had some early with my prior overclocks, but running with stock core/memory and slight undervolt on SMOS, I've only had two restarts in a little over 3 days between two rigs. One rig has 2x 1080Ti (0/0/225W) + 2x 1080 (0/0/155W) and gets a combined 4.19gps poolside (miner reports 4.38gps) on C31 using Luxor, with less than 0.2% rejects. I haven't tested it on any other pools. If you're just looking at 1080Tis, mine report ~1.26 poolside (1.32gps on the miner). I've also got a 2080Ti running at 1.84gps poolside (miner reports 1.91gps) on C31. The new NBMiner looks interesting and I'd like to test it, but I have testing fatigue, so it'll probably be a few days before I get around to it.

Seems that CryptoDredge v0.17.0 supports c29 for 9 days now.
Hopefully will get to try it later on the day.

Added.

is there any mining software for Windows - 4GB AMD GPU ?
I found only for linux.
