Sorry if this has already been covered. I saw a couple other topics like this but they seemed to be more about the network’s coping mechanisms.
If a solar flare instantly fries 10% of the nodes on the network, or some timebomb virus spreads throughout the world and scrambles 10% of the vaults at the same time, would this destroy a huge proportion of large files?
Please correct this maths if necessary…:
Typical futuristic video files: 1 GB
Number of chunks in a video file: 1000
Probability of all copies of a given chunk going down (assuming 4 instances of each chunk and 10% network destruction): 0.1^4=0.0001
Probability of all copies of a given chunk staying available: 0.9999
Probability of all copies of all chunks staying available: 0.9999^1000=0.9048
Number of futuristic video files on the network that become fully unreadable: 9.52%
I’m guessing there’s no way to stop data being lost in catastrophic events. But if I understand this right, a user could reduce their risk of completely losing a video file by splitting it into multiple parts before uploading it to the network, which seems counter-intuitive.
