Is there a way to make it so that readers know that two different messages signed with the same ring came from the same person in that ring?
I don’t know much about cryptography, but why can’t you just build on top of ring signatures by publishing all messages as (plain text message + public key + private key signed message) signed by the ring signature? where the public/private key pair is a throwaway one used in all the messages you want to link together?
Edit: oh then we are not confirming the message comes from the same person, but from the same pseunodymous identity which can be composed of multiple people in the ring.
