Today's internet puts all the files on servers. Servers suck they are like keeping all your files in one big treasure chest that hackers can open pretty easily, and steal everything. Governments can plunder the treasure chest too in many ways, or destroy them if they don't like what's inside. No matter how many locks you try to put on your treasure chest, crafty pirates will always find ways to plunder the booty!!
So instead, MaidSafe is making a way to take all the files on the whole internet (let's call them gold coins / dubloons) and make super strong, super tiny treasure chests for each gold dubloon, and spread them around all the hidden parts of the deep blue sea. They do this by chopping up all the files, encrypting them, and spreading them across everyone's computers. So no matter how crafty the evil pirates are, the only ones who know where all these mini-treasure chests are and have all the keys is you!
No pirate is going to sail all the oceans of the world and fight all the sea monsters to get your one dubloon.
So finally, your files can be safe!
