A few months ago I tried to get into Chia mining which is a cryptocurrency that uses proof of storage space instead of proof of work. You do a one-off expensive (CPU and IO) process to generate a "plot" (~100GB file) and then you can "harvest" that plot continuously for the chance of earning Chia. The more plots you have the more chances you have to win a block and earn some coins.

The price has now dropped below what it would take for me to care about it, I don't currently have the time and I need to storage hardware for something else, however I don't want to waste ~10TB worth of these plots by just deleting them (it took a couple weeks and multiple machines to generate those), so I'm happy to donate them to anyone who's interested.

Email is in my profile. You'll have to download them over the next couple weeks (I'll set up an FTP or something, or you can SSH/rsync, I don't really mind) and I hope you have a fast connection. You'll also get the private key (the wallet recovery passphrase) as it's my understanding that the plots are tied to that.

Enjoy!
