Comment on Is the blockchain an interesting innovation, aside from cryptocurrencies ?
Valmond4@lemmy.mindoki.com 1 year agoYou forget that the blockchain is all about not trusting some middle-man/site, so you need to stock that blockchain yourself, everyone needs to stock that blockchain.
So multiply not only the cost, but also the ecological impact just buying all those drives.
And that’s only for *US" housing (I didn’t get the timeframe you used to calculate it, is it for like year 2050? Old data stays forever.).
BTW found the guy buying 0.5TB Hard drives ;-)

Yes, everyone would need a copy of the 10s-of-GB blockchain. That’s a fraction of the amount of space a single computer game would use, does that seem unreasonable/impractical to you?
And I buy used enterprise 2-3TB drives on eBay :) . I was going to use a 32GB flash drive for my example, but a 500GB HDD is the same price

Fair enough about the size.
Checked out eBay, there are some cheap 2-3Tb drives there! How does it pan out quality wise? I guess they sell them off like after 5 years of usage right?

Yeah, that’s my understanding. Tbh I don’t have a lot of experience with them yet, but I’m building an 8 disk RAID6 array and I decided to go with those used drives. 10 matching disks will be around $120, and I’ll have 2 extra drives so I can rebuild the array asap if a drive fails.
