I have an application on network with database for files sharing , now i am thinking of to move that application on blockchain , my question is how better security will be in blockchain for users files , if private keys lost then that's mean user lost his files ? then how i can make private keys more secure. Thanks
Look into storj https://bitcointalk.org/index.php?topic=702602.0 it's probably more in line with your project and idea. Putting file data into the bitcoin blockchain would be a bad idea due to bloat. You could store a particular hash of a file and put it in OP_RETURN, but the fees at this point would offset the value of doing so.
I wonder if OP does in fact mean what you suggest; blockchain cloud storage. Or perhaps theorizing torrent-like networking.
Interesting. It sounds like you can put the file data (like CRC32 hash) to check for if files are identical and haven't been modified maliciously by other parties. You still need to host the files somehow though, or through torrents?
Yeah this is what I'm thinking too, like how open-source games prove fairness with SHA-Hashes.
