When anons pay the invoice for a post or comment, we can give them a special string they can use to proof to us that they are the ones who created the item. It's not the preimage because any node on the route knows it, not only the author. So instead, we create a hmac based on the invoice hash. If an anon can give us this hmac on edit, it's a proof of authorship.
