Web3 noob here. Is there a guarantee that IPFS and Storj won't go down or delete a file in the next 10 years? How do you ensure that the files are always stored?
Part of the core motivations of ipfs is to make files last forever. The idea is similar to bittorrent (or any p2p file sharing system). There's no guarantee, but it's more likely that a file will be hosted by one of millions of people, over a handful of corporate servers.
