Anybody Farming Chia?

Does this just run on standard OSes?

Every give any thought to farming on AWS? Obviously it becomes a numbers game.

The hardware you’re using now, what is it? Also: is that the only thing that device is doing? Farming Chia? :open_mouth:

Hey BillyBob! Yeah, NVMe is just flash storage, available on newer systems. Fast storage like that is only useful to actually create the plots. The farming is done on USB 3 drives that can be connected to anything. I have seen some documentation of AWS plotting/farming, but as you mention, there’s cost there. I like doing the plotting and farming with spare hardware I’ve got lying around wherever possible.

Hello! ponponwei! That’s just an old server I had laying around. It’s worked okay for plotting, but it guzzles electricity! I think I’d be better off using a gaming PC, or a newer server. Once I knock out my 1k plots on it I’m going to turn it off and farm on a laptop! :slight_smile:

You and @Mondeoman are now making me think about chia lol. And also buying AMD :joy:

Hi Nick,
I wish I had found your thread earlier. You are nearly 3 months ahead of me. But I may have missed a lot of teething trouble. Congratulations on the 2 XCH. Well done.

I am 2 weeks into this by now, with my first plot completed on 27Jul21. I just went over 50 plots in total and aspire to reach the next two milestones - 100 plots, then 1,000 plots. I have about 90TB of capacity, but not yet built into systems - just second hand spinning disks from eBay.

I have two ancient PCs and one modern PC (low spec - only cost £200) generating about 3 + 3 + 7 plots per day. They need looking after though. I have a lot of downtime. We have had intermittent internet over some days - not sure if it’s me messing with our home LAN continuously building and rebuilding PCs and putting them on the network. In total I have downloaded the Chia blockchain 4 times on 4 different machines. An added attraction is also that I got back to the CLI, and have started to use Powershell instead. Around 2Aug21, I found the MadMax plotter and watched countless Youtube vids until I could understand how to put together the most basic of scripts. I felt like a kindergarten kid.

So for me this was a pilot - the first of four mining pilots intended to create some diversification from only investing in crypto. I assigned 2 weeks for the pilot but each time I calculate an interim return on investment, the figures just keep on improving. About a week ago, I found the Chia leaderboard and could not believe that there is someone hosting 10 petabytes (now it’s 20 PiB). So I scaled that down and decided, like you, to complete about 1,000 plots then let a slower system continue in farming mode.

It doesn’t help that at the same time, I have been clearing out my workshop at home, and repurposing it as a potential crypto mining space. It’s clean, dry, not insulated at all but it’s over 200 sq ft and already had a 36U 19 inch rack cabinet (ex bp global datacentre Hemel Hempstead). I am forcing myself to relearn what I forgot about 20 years ago - LAN, WAN, hosting, high level coding. Nice as a hobby and whilst I am not contracting, but I guess I should get back to contracting some time soon.

Anyway, please keep this post going. I am contemplating mining some Helium as the next pilot. The last few days have helped, in that if I need any additional moolah for investment, Cryptos seem to have woken up again, and we are heavily into XRP. Treated my wife to some retail therapy today, invading three local clothes shops and finishing it off with a 5pm coffee and light snack. Truth be known, I think that is something I am becoming really good at - taking my wife on retail therapy trips.

Now back to mining. Just need to watch Max Keiser, Michael Saylor and Bitboy Crypto sell BTC to the moon. They are back on track for predicting a year end price of $200K to $400K plus or minus a bit. God bless them, and I hope they are right. Mega retail therapy sessions would follow for us :money_mouth_face:

I forgot to say - about proof of time and space as opposed to proof of work.

In 2000, I worked for KPMG and managed a London office consolidation of seven sites into one at Canary Wharf. I needed to order some significant kit. Three 42 inch TVs for video conferencing at £7,000 each! Now they are about £200 each. The UK South East also needed a new SAN. I ordered a total of two terabytes of disks in a SAN totalling £150,000. A new 2TB disk is now about £50.

In 2018 I was specifying CCTV disk capacity at a UK major airport. The final disk space required to satisfy all business requirements (mainly for security) was a whopping 5 petabytes that we put on order at a cost of nearly £1M.

Now I find one guy in the space.pool mining Chia with a 10 petabyte capacity.

If anyone was still unsure whether technology moves in a straight line or exponentially, the numbers here should convince them it is the latter.

I want one of those 128 Gb Ramdisks and am trying to cost up doing that with old Dell servers on the cheap. Do you have any estimates of how they would compare with a modern M.2 NVMe drive running on the PCIe bus at 32Gbps? I mean, how long would it take to complete one Chia plot?

Hi @ponponwei

Yaayyyyyhhhhh! I got my first Chia payout yesterday. I earned 0.01 Chia. Whoooppeeeee dooooooooo!

I was beginning to think that I had done something wrong. I am approaching 100 plots, and I got my first payout - equating to about $2.60. That has encouraged me to carry on. The third plotting computer gave up the ghost yesterday and I have had to reload Windows 10. I was worried that I had trashed a SSD drive but it wasn’t the case. It was just after the latest Win10 update (H121?). And it is a computer I bought broken and repaired / upgraded it, so it may still have ghosts in the woodwork or skeletons in the cupboard.

I have also been let down by a clown on eBay who has not delivered my CPU and RAM, so I have requested eBay to intervene and send my funds back. So that has delayed me a couple of weeks in building my super douper plotter. Never mind. I have about 90 terabytes of disks to fill up, and I need to catch up with my documentation (technical infrastructure plan) so perhaps it is a good thing that I have been delayed.

I wonder how long it will be now until I get my next 0.01Chia payout. I wait with bated breath.
:rofl:

Added by edit:
I’ve had to start Madmax script so many times now that I know the Powershell commands off by heart. And I am getting used to preferring Powershell to the CMD prompt (command line interface aka DOS). Who knows where I will end up. Writing EAs?

$2.60!!! lol pls don’t forget about me! :sweat_smile:

Your wife is very lucky! Hope she’s not shopping at name brand stores lol.

Like this? Dolce and Banana

Perfect. Exactly that!

Update. Just added 2 x 4TB full disks to the main farming rig and am now farming 210 plots. Slow boat to China. It is up 52% from my previous total, so happy about that. Meantime, it is taking me a lot longer than I thought to set up the farm I bought. Nevermind - the journey is great. Still buying stuff faster than I can put it to use earning money. At least I won’t get bored with nothing to do.
:rofl:

I understand. I’m still trying to figure out what the best low-energy farming solution is for me. Keep plottin like a super villain!

FWIW if you turn up your debug log you can check your proof time on Windows systems using:

Get-Content “~/.chia/mainnet/log/debug.log” -Wait -Tail 30 | select-string -pattern “plots were eligible” -encoding ASCII

Are you farming solo ? Having started in July I joined a pool.

Yep. I started before the pool protocol was there. I’m sure I’d make more in a pool, but afaik that requires re-plotting. I do prefer being my own little disadvantaged island for some reason. It’s like my personal daily mini-lotto. lol. :slight_smile:

I have attached my rather poor start to farming. I just had to reboot the farm because of an early morning power cut due to some lively LED lights in the kitchen. Same spur as the workshop. Anyway, I am going to race you to 800 and see who gets there first. :money_mouth_face:

Challenge accepted! I think I can crank it up and abuse these NVMEs a bit more before they melt on me!! :rofl:

That’s the spirit. This week I have bought two second hand SSD drives, 2TB each. I see you saying “mistake - these will die any minute”, as an engineer, I am prepared to take that risk. The second hand units have been tested for TBW that equates to around 50% of their maximum value and I paid about 55% of new price for each of these. My interpretation of survival of SSD drives (or NVMe drives) is that the specified TBW numbers are based on warranties and so are conservative. I have the same statistical approach to using eight year old enterprise hard drives. In my work as an IT technical project manager I have observed drives that are well past their five year end of support and into their 10 year end of practical life. The systems get replaced more and more frequently as corporates move more and more storage capacity first to datacentres and then on to cloud, or even cold storage. For large companies, these are multi-million dollar, five year programmes so hard disk availability of old drives is not going to dry up any time soon.

My drive database (50% complete) will track hours in use and restarts, and will contain a link to a CrystalDiskInfo sheet. This will serve as my “drive replacement plan” as I inevitably move from 2TB drives up to 18TB drives in a cost controlled manner somewhat in line with earnings from the farm. For plotting, I will run these till they die, as long as I always have a clone backup of each. These are insurance policies against the loss of the main drive I purchased with the farm last month. I will clone the existing 2TB drive. I am yet to be able to confirm (but believe it to be the case) that the system I have bought can generate about 20 plots per day, and that is 3 times my current system rate of 7 per day. I have gone a bit overboard on buying (I usually do that), and seriously think that I don’t need to buy any more “bits” until I get to about 2,000 plots in total. I have my 210 plots currently on seven drives attached to a Windows 10 tower on a 10 year old system (my son’s broken gaming tower), and that is more than adequate as a farm / harvester.

I now need to complete the transition of the 1,000 plot farm I bought so that it remains farming - I have had some day work to do in between so am behind with that goal. Once I get that “1,000 plot income stream” set up, I will continue to plot on my other 80TB blank storage, building one or two other systems, the first being a Raspberry PI that can farm the existing plots I bought. I will then use the plotter PC I bought with the farm to plot new plots until I fill the 80TB, then gradually move the single farmer plots from the existing Chia account to a new Chia destination to collect farming rewards. When I finish (I have given myself to end of December) I will have a 1,800 plot capacity or thereabouts (200 TiB). At current values I think that will generate about $400 per month gross and a target $300 per month net of electricity and other “improvement” costs. Of course, that could be $100 per month, or could be $900 per month. Depends on others and their appetite for hard work, patience and determination. I am just coming up to 0,1 Chia in total, so this can only go one way, so I need to get those 1,000 plots on line as soon as I can without getting too much distracted with life’s more boring chores.

That’s awesome! I can only crank out like 8-10 plots per day on my system.

CrystalDiskInfo is great! I’ve used it before.

I love all the stuff you’re doing, especially the whole solar thing. I’m thinking about how to get funky with my setup. Doin some research on Pi alternatives opened my eyes to the proliferation of single board computers out there! For my farming rig, I think I’m gonna look for one with eMMC storage so my proof times stay low and try to get creative with it. I’m picturing a bronze Cthulhu statue with HDD activity blinking eyes and tentacles holding 14TB HDDs or something fun like that. :grin:
