Mining using your disks free space

If you heard “mining”, you will think about heavy computing using GPU. However, recently many new algorithms based on data space appeared. We can classify them in two main categories:

  • Sharing your free space to users and reward you for that
  • Using your free space for using a consensus called Proof of Space and Time (PoST)

We will list and compare some of them in this article. We tried to keep the article as simple as possible, you can check links to get more details. Maybe, you can earn even more using your SSD/HardDisk at the same time as your GPU. This article is a first version, and it will be improved later.

How to become rich ?

Sharing your free space

The most famous names are Filecoin and Filebase. However, the latter is based on Storj, Sia, Skynet network (you can earn reward joining those networks).

Filecoin

Minimal requirements

  • 8-core CPU and 32 GiB RAM
  • Enough space to store the current Lotus chain (preferably on an SSD storage medium). The chain grows at approximately 38 GiB per day

Requirements if you want to earn money

  • 128 GiB of RAM are needed at the very least. This should be complemented with 256 GiB of swap on a very fast NVMe SSD storage medium.
  • A minimal amount of 1TiB NVMe-based disk space for cache storage is recommended.

Storj

Minimal requirements

  • 8 TB and a maximum of 24 TB of available space per node
    (Minimum of 550 GB with no maximum of available space per node)
  • Uptime (online and operational) of 99.5% per month

Potential rewards

  • $1.50 per TB for storage
  • $20 per TB for bandwidth
  • $10 per TB for repair bandwidth

Sia

Minimal requirements

  • At least 100Gb of free space to offer
  • A static public IP address
  • A reliable connection, with the hosting computer being available 24 hours per day, 7 days per week. An availability of 97% of the time (uptime) is required
  • A minimum of 2000SC (about 20$) for setting up Collateral

Potential rewards

It is only a guess, but rewards can be something like 500SC (5$) for 2TB.

Skynet

Skynet uses Sia network.

Proof of Space and Time

Chia network

Minimal requirements

  • Quad core 1.5Ghz CPU
  • 2 GB Ram

Potential reward

$5.34 / month for 1TB.

Conclusion

To conclude we can say, that sharing your free disk space for money requires a very stable environment, a fast connection and several TB of free space on SSD. It is not the case of most of personal computers and not the case of my computer, so I could not try.

The Proof of Space can be a little more easy to set up and usual computer. However, the first reward could take several months. In addition, if you want to try, Chia node is supposed to be executable on a Raspberry Pi 4.
