First we need to explain bitfield versus no bitfield plotting. Originally, the plotter did not use bitfield back sorting. The bitfield back sort is theoretically faster than not using the bitfield and we already know that it saves 12% of total writes but requires more RAM. We have a hunch we can speed bitfield up 10% and make it work on more processors but that’s not in there yet. What we do know is that, as long as you’re ok with the 12% more total writes, no bitfield will work faster when SSD or fast SAS is your temporary directory. If your temporary directory is on a regular HDD, like mine is, bitfield is 20% faster than no bitfield. Older CPUs may not see the speed increase as much as noted above.

Returning to the rules, here are a few. Never touch the stripe size of 65536. No one has found a speed up over that value and we are likely removing it from the options list.

These are 101.3GiB, 108GB or 106,000,000kB (stupid Windows displaying in kilobytes)

Step 5 – Farming

To start farming, you need the full node to be synced. Remember this takes a day or so. When the database is fully synced and you have the latest and fully validated copy of the blockchain, you will see it say “Synced”

Click on the farming tab, you should see your plots show up here. If they are not, click add directory and find your HDD where the plots are located.
If you are farming correctly, they should show up green like this!

If you selected self-pool above, now you will want to join a pool so you can actually get some farming rewards.

Update: as of 3/11/21 stripe size has been removed as an option.) You almost never want to use any bucket values other than 128. Less buckets requires more RAM for each plotting process. 64 buckets requires twice the RAM.

As far as number of threads are concerned you are generally going to want 2 to 4. More than 4 seems to have diminishing returns and 2 threads is a lot better than 1.

More threads also require a bit more memory to successfully complete a plot. The threading is only used in phase 1 currently.

As of Chia 1.0.4, RAM requirements are almost identical between bitfield and no bitfield. This is a chart of the various RAM choices assuming a k32 with 128 buckets and 2 to 4 threads:

RAM MiB:MinimumMediumMaximumBitfield90026403400No Bitfield90026403400

Below minimum your plot will fail.


Medium is enough RAM that you’ll get most speed improvements, but not all.

Often you’re getting amazing speed because you’re using the turbo core of that multi core processor. The folks who plot the most have shown that you should measure in TB (TiB if you’re old school like us) per day. The way to get the maximum TB/day is to plot lots of plots in parallel.
Some of the top plotters use datacenter SSDs. Some use SAS drives. Raid 0 is often very handy to tie together a couple of small fast drives into one say 2TB partition so you could fit 5 k32 temporary spaces on that one virtual RAID drive.

All of that said, for my personal plotting I use a 2017 iMac and a 12TB Western Digital external drive on USB 3.0 for both temporary and final directory, and I get a k32 about every 10 hours.

Good assumptions

There are some good rules of thumb for now. These can change as we will be returning to making some plotting speed improvements after launch.

Introduction

First it is important to know that there are two very different parts of being a Chia farmer. There is creating the plots or plotting and then there is farming the plots. In this post we are going to focus on the process of creating your plots. The types of machines and storage space are very different than the types of hardware you ultimately want to use to farm. You can see some example farming rigs on our very useful repository wiki.

We initially recommend that you try plotting with what you have around. The only caution about that is that you want to limit the amount of plots you create that use your internal/consumer grade SSD as the temporary space. SSDs have very different wear lives and we have detailed information on SSD endurance.

You really never need to plot a plot with a k size larger than 32.

If you followed some of our guides, you will see that if you are also plotting, you will want a dedicated SSD for temporary storage. Consumer M.2 will work ok if you are plotting just a few hard drives, but if you are getting serious about Chia you will want to buy a used data center SSD that has good endurance (how much data you can write to the drive before it wears out), and sustained write bandwidth (for fast plotting speeds!).

Step 2 – Install Chia

Go to chia.net/download and click on Windows. This version of the guide was based on the beta of 1.3, and the latest production version will always be right here on the top.

Select Farming Mode

This little Windows firewall thing will pop up twice, for now just click accept.

All you need is your same 24 word mnemonic on both machines. Alternatively you can just run a remote harvester on your Pi and have it connect to your gaming machine where you are running node and farmer and only have your private keys on one machine.

Learning more

Everyone trying to create plots should read through our repository FAQ. It really does answer 90% of the questions you might have about plotting (and farming.)

Once you have read the FAQ, you’ll find a supportive community in these channels on our public Keybase channels.

How to mine chia coin in india

Near the end of March, I heard about Chia, a fairly new crypto that claims to be “green,” because instead of relying on power-hungry GPUs for mining, Chia uses Proof of Space and Time. I don’t fully understand the approach (that goes for any crypto), but I do know this protocol relies on storage space and comparing challenges issued by the blockchain to hashes stored in the plots on your spare storage space.

The company’s thinking is that anyone can farm for Chia with the spare hard drive space they already have, with little or no investment required. After being hesitant to get into crypto for years, I decided that Chia was as good of a chance as any to get in at the ground level and see how many coins I could farm. So, I started buying WD EasyStore drives from Best Buy, which were affordable at the time.

For the last few years, I’ve had a group of friends who tried to convince me to start mining Ethereum. I have access to a few gaming computers and the required GPUs to mine to make a passive income. I resisted for as long as I could, only because it seemed like a somewhat intimidating project to tackle.

I eventually gave in and have been mining Ethereum off and on for the last six months or so, learning as I go — both about the different mining pools and the coming changes to Ethereum but also about crypto as a whole.

I’m not rich yet. The money I have made hasn’t been a lot, but it’s been a fun hobby if nothing else.

Those who do plot larger are either doing them to show off (and we encourage this for fun) or to optimally fill the open space on a specific drive. A k32 will take up 101.3 GiB of space once completed but will need a total of 239 GiB of temporary space as it is being created. A single k32 plotting process never needs more than 239 GiB of space.

One needs to be careful here as 239 gibibytes uses 1024 as its divisor where GB or gigabytes uses 1000 as the divisor. That means you will need 256.6 GB of temporary space and the final plot file will take 108.8 GB. A k32 plot can be done by one expert we know in just under 4 hours, but most experts are creating plots in 5 hours and most folks average around 9-12 hours.

Creating a plot is a process that will take RAM, CPU cycles, IO to your disks and it will use them differently in each of the four phases of plotting.

When trying to figure out how long the shortage and the price increases would last, I reached out to a few storage vendors to get their take on Chia and the impact it was having.

Larry O’Connor CEO at Other World Computing (OWC) took a few minutes to reply about how he and his company views Chia and the impact it’s had on not only OWC but the storage industry as a whole. O’Connor confirmed what I already knew: “The impact on hard drive supply and cost has been substantial.”

At the time when we spoke in mid-May, Chia’s network space was 6EiB — that’s Exbibytes — but as of July 8, it’s hovering at 30EiB.

The start of the Chia network growth came at almost the same time as Amazon’s $300-million purchase of high-capacity drives, according to O’Connor.

Remember any form of investing comes with significant risks. Why are we mining Chia? Well, because graphics cards are hard to get at a fair price, but still, we can get a lot of hard drives. If you look at the calculator they have posted online, you can make about $12 per month per one TB (terabyte).

We don’t actually know if this is accurate because there is still no listings of it (UPDATE: check current price). Currently, we will have to see exactly what the exchange rate is going to be. Because as you can see here, the exchange rate is they are projecting it to be around $20.

So for the coin, which could be true or could not be true, it could be worth a dollar. On the other side, you may check futures prices on Hotbit here.
