I have 1 Bitcoin therefore blockchain will succeed.
I have no idea why a company would use blockchain for logistics or file storage considering how its massively expensive to constantly pay miners for transactions.
My centralized server can do everything needed for logistics or file storage.
Benefits of blockchain are overblown. There are uses, but centralized servers are really good.
Now I agree that a lot of ideas for how blockchain will be used are just unnecessary and stupid, but there are some good ones as well.
You mentioned file storage but actually I think blockchain could be useful for this. Allow me to elaborate.
I don’t want to rely on Dropbox or Google or any other single company for the long-term storageof my data. And I don’t want to accidentally upload unencrypted data. And I don’t want a single company to decide what platforms they will support.
I want an open protocol and a nice open source client. Different people have different wishes. For me that would be far more attractive than the centralized storage you are suggesting, because it’s not just about the servers and the storage it’s also about the people and the software ecosystem around it.
And besides, if I gave like hundreds of GB of data to one company then they could easily start charging me more in the future and I might not be able to do much about it. With a distributed system I think there is a better chance that competition might drive prices down more.
And that’s just one kind of use-case. There are more as well.
I think blockchain in general is cool and also I like projects that aim to make worldwide payment be really fast and cheap and for the banks to hold less power over my money.
What's the point of the blockchain?
Dropbox got a similar response, no? That it can be replaced by rsync.
The point of the blockchain is to allow me to rent storage space on other people’s computers.
Wasabi and B2 are pretty much the only commercial services which could even attempt to compete on price with something like Sia today (Filecoin and others in the future potentially), but they're only in single DCs and if they lose your data you have no one to go after. In the cryptocurrency-based systems, this is all automated.
For as many incredibly stupid and useless applications of blockchains as there are, this isn't one of them in my opinion. It may not be unique, but it's actually something that could have a competitive edge over a centralized service.
You're missing OVH, which has multiple DCs.
Automating the upload to different endpoints is not exactly something exclusive to the blockchain, I already have that with git-annex.
It would be nice to see Sia/Filecoin provide some basic DB metrics like availability, durability, latency, bandwidth... things that any prospective client would absolutely need to know.
