I am not a Bitcoin miner nor am I a Chia coin farmer, and my knowledge and experience in both are very shallow. But I recently became interested in the 2 main activities of Chia – plotting and farming, because they both involved storage. I am writing this blog to find out more and document about my learning experience.
[ NB: This blog does not help you make money. It is just informational from a storage technology perspective. ]
Proof of Space and Time
Bitcoin is based on Proof-of-Work (PoW). In a nutshell, there is a complex mathematical puzzle to be solved. Bitcoin miners compete to solve this puzzle and the process uses high computational processing to solve it. Once solved, the miners are rewarded for their work.
Newer entrants like Filecoin and Chia coin (XCH) use an alternate method which is Proof-of-Space (PoS) to validate and verify the transactions. Instead of miners, Chia coin farmers have to prove to have a legitimate amount of disk and/or memory space to solve a mathematical puzzle, conceptually similar to the one in Bitcoin mining. In the beginning, this was great for folks who have unused disk space that can be “rented” out to store the crypto stuff (Note: I am not familiar with the terminology yet, and I did not want to use the word “crypto tokens” incorrectly). Storj was one of the early vendors that I remember in this space touting this method but I have not followed them for a while. Their business model might have changed.
A funny thing came up on my Twitter feed last week. There was an ongoing online voting battle pitting FreeNAS™ (now shall be known as TrueNAS® CORE) against Unraid. I wasn’t aware of it before that and I would not comment about Unraid because I have no experience with the software. But let me share with you my philosophy and my thoughts why I would choose TrueNAS® CORE over Unraid and of course TrueNAS® Enterprise along with it. We have to bear in mind that TrueNAS® SCALE is in development and will soon be here next year in 2021.

The real proving grounds
I have been in enterprise storage for a long time. If I were to count the days I entered the industry, that was more than 28 years ago. When people talked about their first PC (personal computer), they would say Atari or Commodore 64, or something retro that was meant for home use. Not me.
My first computer I was affiliated with was a SUN SPARC®station 2 (SS2). I took it home (from the company I was working with), opened it apart, and learned about the SBUS. My computer life started with a technology that was meant for the businesses, for the enterprise. Heck, I even installed and supported a few of the Sun E10000 for 2 years when I was with Sun Microsystems. Since that SS2, my pursuit of knowledge, experience and worldview evolved around storage technologies for the enterprise.
Open source software has also always interested me. I tried a few file systems including Lustre®, that parallel file system that powered some of the world’s supercomputers and I am a certified BeeGFS® Systems Engineer too. In the end, for me, and for many, the real proving grounds isn’t on personal and home use. It is about a storage systems and an OS that are built for the enterprise.
