In order to fetch an ipfs object, one needs a hash. Does this hash sometimes leak to other nodes who didn’t know it beforehand, or can one rely on the fact that in order to fetch an object one has to know the hash in some way?
Along the same idea, is it possible to store data pinned in an ipns record privately, if the ipns record is kept private? (this question assumes the ongoing work on using an ipns key different from the node ip is complete)
