Rules (interactive)

Rule 1- All posts must be legitimate questions. All post titles must include a question.

Rule 4- No self promotion or upvote-farming of any kind.

That's it.

Rule 5- No baiting or sealioning or promoting an agenda.

Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.

Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

Rule 8- All comments should try to stay relevant to their parent content.

Rule 9- Reposts from other platforms are not allowed.

Is the blockchain an interesting innovation, aside from cryptocurrencies ? (self.nostupidquestions)

For a long time, I thought of the blockchain as almost synonymous with cryptocurrencies, so as I saw stuff like "Odyssey" and "lbry" appearing and being "based on the blockchain", my first thought was that it was another crypto scam. Then, I just got reminded of it and started looking more into it, and it just seemed like regular torrenting. For example, what's the big innovation separating Odyssey from Peertube, which is also decentralized and also uses P2P? And what part of it does the blockchain really play, that couldn't be done with regular P2P? More generally, and looking at the futur, does the blockchain offer new possibilities that the fediverse or pre-existing protocols don't have?

You 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.

Edit: I also backup all of my important files, so it wouldn't be the end of the world if the entire array fails. And a little downtime isn't that big of a deal for my home server, unlike a commercial data center.
