It seems plausible to imagine a system where PeerPub could retain their "published author to register This model relies on t a blind cryptographic signature.(https://en.wikipedia.org/wiki/Blind_signature https://en.wikipedia.org/wiki/Blind_signature) PeerPub generates a public/private key pair. 1. Alice wishes to register on PeerPub. She generates a Nonce N. 2. She blinds the nonce with a factor B. 3. She submits the blinded nonce and her identity to PeerPub. PeerPub checks her credentials and executes a blind signature of the number and returns it to Alice. 4.Alice now separately registers an account perhaps using a privacy protecting system like Tor. She uses the original N and the unblinded Signature. 5. PeerPub verifies N + signature and registers the account. PeerPub will have no way of linking N to the original credentials. PeerPub can record N and make sure it can only be used once to register an account.
