[SC2] just another Proof-of-Storage coin

I'm still around with the idea, just would like to see more interest from people, they want to see something in action, but one man can't do everything, that is not fun.

siacoin is for sharing files publicly like bittorrent. The network hides the identity of the person uploading the files. Yet this concept is closer to SF2 but different purpose.

Hey, Siacoin dev here. Siacoin can definitely be used for personal and private files, needing only that encryption be applied. Once we have a beta, all files will be encrypted by default, unless the user explicitly specifies that the file should not be encrypted.

Of the multiple cloud storage protocols under development (Ethereum's seems to have, MaidSAFE's got one, there's datacoin, there's Sia, Storj, Filecoin.io, Filecoin.org, and potentially others as well), is there a particular reason that you've chosen to make your own? Would you be interested in seeing your particular use cases weaved into another proof-of-storage coin? Sia in particular is meant to be the cheapest available cloud storage solution, in addition to being very fast and robust, private and secure, and of course decentralized.

Happy to see more people working in this space of course, the more thought that goes into this type of project, the closer a full fledged proof-of-storage coin is to reality.

Hey Taek! Glad to have feedback from you. I'm worried about brute force attacks, since the chain is public, if someone has a copy of it, a powerful computer in the near future could decrypt the files. What is your approach to that?

SC2 tries to be libre, so everyone can use the network, yet the market needs several alternatives, there is no fun without competition.

Me too!

The best defense you're going to have against brute force attacks is keeping the encryption algorithm out of the specification, and instead make it client side.

For standard, non-quantum computing, your usual AES/Twofish/Serpent encryption at 256bits is going to be sufficient to stop anything for the next few decades, even if non-quantum computers get much, much faster and computing clusers also get much, much larger. If you're worried about 1 being broken (because the crypto gets reversed or something), you can chain them together. This will make encryption a lot slower, but then in order to break through, all 3 of the algorithms will have to be broken. (Chaining essentially makes your encryption as strong as the strongest of the 3 - not stronger, but since you don't know which of the 3 is the strongest (none have been broken yet), it's still a useful thing to do).

For quantum computing, I don't think there's an encryption algorithm that's been created which is safe from quantum attacks. Luckily, quantum computers are probably a few decades away from being able to tackle standard encryption tools. But if IBM suddenly releases a really powerful quantum computer, I don't think there's anything we can do about it. So instead you just have to make your protocol able to adjust as soon as better encryption techniques are developed.
