Chia is a great fiber supplement for your diet. But have you considered it as a supplement to your cryptocurrency mining?
Chia is a proof-of-space-and-time cryptocurrency, invented by Bittorrent creator Bram Cohen and inspired/designed after Satoshi Nakamoto’s original Bitcoin paper. You can read plenty of the underlying details and math around it at chia.net, but what I’ll be covering here is an introduction to how Chia works for the person making it, and how to get started with Chia.
You should read this post first, but I have hardware suggestions in another post, and both the chia.net website and chiadecentral.com have plenty of ideas as well.
There is a Frequently Ungoogled Chia Questions post available as of May 11, 2021; it will get most updates, although if anything in this post becomes totally wrong, I will fix it.
I wrote up my NUC plotter build step by step.
I also need to note that, while I appreciate all of the feedback and the record-setting number of viewers to this post, I cannot provide free consulting and rig reviews to everyone who submits a configuration. I’m happy to try to address specific questions in the comments, but general “help me get started” and “what hardware should I use” questions are answered in these posts and I won’t be able to review everyone.
First, The Caveats
Read this post, and some of the linked resources, but the best thing to do is to start with what you have on hand. A big part of the design of Chia is to use reusable components (unlike ASIC mining and even certain GPU mining, which eventually outgrows the components, which will then be less useful for any other use).
If you have a modern desktop with 8+ CPU threads, 16GB or more of RAM, at least 300GB of free SSD space and at least a few terabytes of HDD, you’re good to go.
If you don’t have anything like that, I’ll share my own configurations below, as well as some hardware lists in an accompanying post to help you find a manageable starter farm for around $1000 and another more scalable one for under $2000 (less if you start from an existing system or components) . You can also find hundreds of tested configs on the Chia subreddit and various blogs.
If you decide later to invest thousands of dollars in hard drives, SSD, big CPUs, and lots of RAM, you’ll better understand how the process works and where to put your money. Or if you’re like me and have a pile of old servers in the garage, you’ll be able to upgrade what you already have and make the most of it.
If you’re using an SSD or NVMe drive for plotting, the plotting process will wear out the SSD eventually. A single plot uses up to 1.8TB of writes. Check your drive specs and figure out what lifespan to expect, and don’t use your boot disk as plotting space. As examples, the 1TB Samsung SSD980 SSD is rated for 600TBW, or 333 plots (including failed ones), for $130. A Seagate Firecuda 520 1TB is rated for 1800TBW, or 1000 plots, for about $180. So spending about 50% more gets you 3x the endurance.
And don’t expect to get rich on day one. For starters, Chia transactions don’t open up until May, so you can’t do anything with your Chia until then. And it may take you days, weeks, or months to find Chia, and none of us know yet where the value of the currency will go. Calculator sites are estimating $20. Some speculative sellers are looking at a lot more than that. But today, it’s just pre-farming and getting ready for the full launch next month.
