- samatman 5y agoUnfortunately, stale hashes are a worse problem in content-centric networks than dead links. So Alice links to some content in Bob's site, but Bob made an embarrassing error and wants to update it. Very well, and Alice has to update the hash pointing to Bob's content: but now any hash pointing to Alice's content is stale, and so on, ad infinitum. There are ways to solve this problem, but none of them force a linear forward history. Basically, you can request all Merkle chains featuring a base hash, and verify that Bob signed all of the branches, but only discipline can keep this collection in a linear order. This is probably fine in practice, just follow the longest branch. And now you have Secure Scuttlebutt!
