Are you mining Grin on testnet and soon on mainnet?

The Grin mainnet will launch on January 15th 2019.

"Meet Grin - the private & lightweight mimblewimble blockchain"

What's Grin?
Electronic transactions for all. Without censorship or restrictions.
Grin empowers anyone to transact or save modern money without the fear of external control or oppression. Grin is designed for the decades to come, not just tomorrow. Grin wants to be usable by everyone, regardless of borders, culture, skills or access.

Private
Grin has no amounts and no addresses. Transactions can be trivially aggregated. To hide where a newly created transaction comes from, it gets relayed privately (a "random walk") among peers before it is publicly announced.

Scalable
MimbleWimble leverages cryptography to allow most of the past transaction data to be removed. This guarantees Grin won't crumble under its own weight in the long term.

Open
Grin is developed openly, by developers distributed all over the world. It's not controlled by any company, foundation or individual. The coin distribution is designed to be as fair (but not gratis) as is known to be possible.

Grin's Proof-of-Work
This document is meant to outline, at a level suitable for someone without prior knowledge, the algorithms and processes currently involved in Grin's Proof-of-Work system. We'll start with a general overview of cycles in a graph and the Cuckoo Cycle algorithm which forms the basis of Grin's proof-of-work. We'll then move on to Grin-specific details, which will outline the other systems that combine with Cuckoo Cycle to form the entirety of mining in Grin.

Please note that Grin is currently under active development, and any and all of this is subject to (and will) change before a general release.

I hope that Vitalik Buterin’s idea of building a supercomputer and running Ethereum 2.0 will kill the mining.

I think mining is one of the major flaws in modern cryptocurrency

If you're interested in Grin mining make sure to check out the latest discussions in the Grin forum. There's a lot of discussion going on and all are welcome.

Yes I have been following Grin forums and channels and it 's really convincing on why not giving a try mining your coin.I find grin has a good use cases and great teams. I think I am giving a grin 4 stars out of 5 at the moment and we'll see after the mainnet.

transactions which are quite unique but good to have. Besides Grin provide services that are quite practical and are also safer to use for transactions as well as storage. This is a form of modern mining system is good and will be very useful to use.

What are your CPU hashrates like? I'm seeing 0.3 g/s on some Ivy Bridge procs using Cuckatoo.

Mining GRIN and stacking LUDOS (after ICO) and Zil are my only plays for 2019. Will GRIN become unmineable soon?

GRIN's mainnet is expected to be launched around January 15, 2019(UTC). BitMesh will open GRIN deposit and withdrawal as soon as GRIN's mainnet becomes online. https://bitmesh.com/exchange?market=btc_grin#/ (https://bitmesh.com/exchange?market=btc_grin#/)

put together a video guide on how to mine grin on windows + linux -- hope it helps :D

Having an extremely tough genesis block - fair mining or not?  ;D Personally yes, since it prevents people from gaming the blockchain in the beginning and is generally pretty fair for everyone, despite only finding the first block few hours later.

Im attempting to mine Grincoin using gringold miner and f2pool.  When I start the miner it recognized the 7 1070 8gb gpus.  When it gets to the 5th, 6th and 7th, card I get a Video Memory Error.  What do I need to do to get all 7 cards mining?

Make your virtual memory 56 gigabytes.

Thank you very much.  That did it.

What is the improvement compared to Monero or Dash ?

I'm glad it worked for you. Miner needs like 7-8 gb virtual memory per card, maybe it can do it with lower, but i'm to lazy to test it :).

Only getting about 1 graph per second lol. Not enough video cards for me to mine.

I have read the GPU mining guide and yes, it really requires around that size to be able to mine grin.

We just published a Step by Step guide on how to mine Grin as we have done so ourselves here. Thought would be good to share, but Windows only for now :)

https://www.coingecko.com/buzz/how-to-mine-grin

Nice, already mining. :)

But no windows wallet, just for linux and OSX?  :(

Yeah what we ended up doing is setting up a VM using Virtualbox for Linux. Download the wallet there.
We plan to write follow up guide on this for Windows users.

IMHO, the mimblewimble (spelling?) is a protocol...and grin coin has this as its ONLY angle for a coin. What happens when a mess of altcoins, that have watched 95% or whatever

value decrease..and are having a pity party and say wtf...and add mimblewimble(spelling?) to their coin that says has other angles and hooks in their protocol besides just the grin

mimblewimble protocol? Would not grin, as a 1 coin wonder, not be lost in the shuffle of other altcoins also getting the protocol?

Also, this may be the kiss of death on grin coin

it has been out 2 days or so ..and they are making an ASIC :)

https://obelisksc1store.tech/product/obelisk-grn1/ (https://obelisksc1store.tech/product/obelisk-grn1/)

everybody and his brother ...IMHO..with the large value drop.... will add this protocol in some manner...as a new hook for their altcoins IMHO....in that mimblewimble was originally

made to add on to Bitcoin...I don't see this as an issue...

anyway, coin is out 2 days and an asic is announced...if the grin coin devs were smart they'd announce if that happens they will kill the asic with an algo change...by the end of the week

crypto always a circus.

why is there GRIN 29 and GRIN 31 algos?? gpu and asic versions?

They intentionally targeted an ASIC friendly algorithm and want ASICs to join the network. Obelisk worked with Grin's team while implementing their prototypes, even though they weren't directly contracted.

anyone know work pool for grin coin? I have tryed with grinmint.com and its looks like scam. My miner work but there is no anyone on dashboard

maybe is it your worker, if you have blabla@mail.com.worker it doesn't work, you will see a dashboard empty for your email blabla@mail.com but you see a dashboard ok for blabla@mail.com.worker , i think it's preferable to remove worker, or you need to add "/" instead of "." between your email and worker, but few miner support this feature

My rigs don't have a big enough HD for a pagefile bigger than 32GB, is there any way around this?

Use Linux. The mining process doesn't actually use any storage on the disk, Windows is just inane and requires disk to back virtual memory.

I don't know the first thing about Linux, plus all my alternative miners are set up for W10, so it's this or nothing I'm afraid.

This pool doesn't show your cards if you don't put in BAT file the name of the rig in format "/rig". That's why it is impossible to use bminer (it has format ".rig"). I tried this pool and lost my time and wasted shares. If I tried to use bminer  without name of the rig, this pool showed only one rig. I agrr with you, they are scammers.

You need larger disks or more actual RAM then, it's unavoidable. You could just use large USB keys for the OS, to save money.

This pool doesn't recognize blabla@mail.com.worker. If you wish to use format "/" than you have to use GrinNbminer or GrinGoldMiner.

Curious. Name a GPU card and/or rig setup and what are you actually mining in actual GRIN per day (more or less)

just asking

thanks

7 evga 1070 (bminer) mining about 2.4 grin in 24 hours according to f2pool

I'm currently mining with 8 CPUs at about 0.4 GPS. Yes I know it's not so much. But I'm getting grin.

When will we be able to use 4gb cards?

Currently it is impossible. Maybe in the future there will be some miner doing double work on GPUs with small amount of memory. But their hashrate will be significantly slower.

I put together an updated video guide showcasing the faster GRIN miner on Windows & Linux for Nvidia & AMD + How to Buy & Sell GRIN + How to turn your mined GRIN into BTC (if desired)

https://i.imgur.com/FryV5ZOl.gif (https://imgur.com/FryV5ZO)

is there any faster miner for grin and AMD then GGM?

have you tried any of the bminer builds?

Does it support Grin with AMD (rx500 or vega series) cards? I think it says it supports AMD overall but not sure about grin?

Try to use profit calculator: https://www.coingecko.com/en/coins/grin/mining_calculator (https://www.coingecko.com/en/coins/grin/mining_calculator)

it does not

Thanks vosk, helpful in getting me up and running.  Difficulty is getting crazy, GPU mining needed a coin like this to come out to offset some other coin difficulties.

I'm using GrinPro 1.1 through AwesomeMiner for 4 XFX - AMD Radeon RX 570 RS Black Edition 8GB GDDR5 PCI Express 3.0 Graphics Cards (RX-570P8DBDR) and I'm getting 6.4H/s at ~525W. I have a feeling that it can perform better but I can't figure out what's going on with these cards. I just installed them so I haven't flashed any bios or anything. I was actually reading that I didn't have to because it has the dual bios switch (handy.) But for ETH I'm only getting ~110MH/s for the four cards. So I'm guessing that 6.4H/s is going to be about as good as it's going to get. :(

Mining a few rigs seems okay.

I,m getting about 1.7 @ 90w per card.

Grin coin is not really so profitable as it seems. That's why developpers don't release any miner for it. If there will be good profit than a lot of new miners will appear.

What are your OC settings?
I'm at 1150/1950

Seems one GTX1070 at 130W power consumption gives practically the same hashrate as three RX570. Is it still so profitable to mine GRIN with AMD GPUs ?

My Rx480 8GB 1310/2000 - ~2g/s @ 100-110W
But you do not need to look for a dependence on the core/memory frequency and even more so to compare with ETH mining. Because the main indicator for Cuckoo Cycle algo is memory bandwidth (https://github.com/mimblewimble/grin/blob/master/doc/pow/pow.md (https://github.com/mimblewimble/grin/blob/master/doc/pow/pow.md)). And the memory frequency is secondary (according to my observations).
For example, RX480 and 1070 have the same bandwidth 256 and the memory frequency 2000MHz (6Gbps), but the 1070 is more than twice is more hashrate (~4.6 g/s).

Well... I get about 4.2 per 1070 at about 110w (ave) and at 80% power limit.
My OC settings are:
80% PL
50 CC
700 Mem

So with my 8 GTX 1070 I average about 33.5 to 34 which brings about 1 Grin a day.

For my 4 RX 570 8gb (XFX with bios mod switch without any bios edits) I only average about 1.65 each with an average of 130W as well. I'm still fishing for optimal OC settings though but it seems that 1.65 - 1.7 is normal.
That only brings in 6.5 which is only 0.1918325 Grin a day.
So yeah... AMD cards currently suck at Grin. Even if I had 8 RX 570 (like my GTX 1070 rig) I figure that I'd be using over 1,000W for only 0.4 Grin a day. I'd actually be losing money at the current price per Grin on my AMD setup.
HOWEVER...
I'm being optimistic. (Not so much that I'm rushing out to fill up on RX 570 cards.)
For my 1070 rig (of 8 Founders Edition cards) I was only getting about 2 Grin a day with gminer a few weeks ago.
Then I switched to bminer and it jumped up by about 25% instantly. Now I'm getting over 4 by simply updating the miner software. I got a little excited by this which is why I bought these 4 570's for about $175 each because I was expecting the same results as soon as bminer started working for AMD. Unfortunately, this hasn't been the case... yet. But the devs are working hard to give us the most that we can earn from them. I can't complain really because in two weeks I've earned 20.3 Grin (at $8.28) and 83.3 Beam (at $2.16) so in conclusion this was a quick and easy $348 during a bear market. So I'm keeping both of them running hoping that things turn around soon and that mining software improves. Especially for AMD cards.

Yes, but meh

dang. thats quite a difference.

Very, let's hope that the devs can tweak the software enough to make mining Grin with AMD cards profitable.

all the good devs that invest in AMD miners are in CN algo - not many miners out there for ethhash or similar algos...that the problem now...doc, jce, teamred had many experience with AMD cards, but not with the algo
i hope one of them know the potential incoming fee if they can tweak AMD GPU for grin (maybe also BEAM) if they can reach same level that vega hits with (for example) lolminer´s eth performance (without the pill the vega outperform 1080 ti)

For folks who are new to mining Grin, we have some step by step guides
Bminer: https://www.coingecko.com/buzz/how-to-mine-grin-coin-with-bminer-step-by-step-guide
GrinGold: https://www.coingecko.com/buzz/how-to-use-grin-wallet-to-send-receive-grin-coins

Anyone here actually managed to get Grin mining with the even older AMD gpus like the Radeon 7970/280X or the R9 290?

I am going to guess that they aren't supported by the software or have horrible speeds since even the RX 470 perform horribly bad against the Nvidia counterparts.

Luxor's GRIN Mining Pool

At Luxor (http://grin.luxor.tech/) we’ve been following MimbleWimble and Grin in particular for a few months now. We’re very excited to join the Grin community as we share some of its core values: Decentralization & True Privacy.

We want to see this project thrive, that’s why we decided to support this project by creating a high-quality mining pool. We’re releasing our first iteration of User Accounts along with the Grin Mining Pool!

On top of that we set aside a few hours of our team to do some research about Grin and put along a few interesting articles to help the community:

    Grin: The First MimbleWimble Implementation (https://medium.com/luxor/grin-the-first-mimblewimble-implementation-9a49a30517ac)

    How to start mining GRIN (https://medium.com/luxor/how-to-start-mining-grin-1e50623b0642)

    How to install and run a Grin Node + Wallet (https://medium.com/luxor/how-to-install-and-run-a-grin-node-wallet-32f344591478)

    Luxor x BitMesh Withdrawal Guide (https://medium.com/luxor/luxor-x-bitmesh-withdrawal-guide-befb6238aef8)

We decided to donate to the Core-Devs to continue funding development! We’re thrilled to become Grin’s Friends (https://grin-tech.org/friends.html).

We also developed a mining calculator for C29, C31, and C32: http://grin.luxor.tech/statistics

Looking forward to seeing everyone at our Discord Channel (https://discordapp.com/invite/AHvsqbW) and keep talking about Grin & MimbleWimble.

My Mining results on Grin

Windows 10
Bminer 14.1
Evga 2080 xc ultra

Here are my max stable overclocks, anything higher than these tends to be unstable or crashes, best to treat these like 1080 ti 1080 gtx
when overclocking instead of the 1070 or 1070 ti.

70 TDP, +125 core clock, + 175 memory clock  Results = 7.38 G/s Fidelity 1.03   145-155W

Overall I am impressed with the 2080 rtx when mining grin

Anyone figured out how to mine to a KuCoin wallet with bminer?

Go to grip-pool.org , register there and you can send easily to kukoin.

I have several GPUs but atm I don't yet to try to mine GRIN. does is a profitable (please don't suggest me to jump mining calculator web). I just want to hear by the real miners

do you know about any grin29 miner that can work 6gb cards in windows 10 apart of  nbmiber? Do you know about any better amd grin29 miner then grin pro?

f2pool is very good as well.
