Proof-of-Membership (PoM)

A Proof-of-Non-Publication isn’t very useful if you can’t prove that some member q is in the audience P. In particular, if you are to evaluate a proof-of-membership, q is yourself, and you want assurance you are in that audience. In the case of our newspaper analogy because we know what today’s date is, and we trust the newspaper never to publish two different editions with the same date we can be certain we have searched all possible issues where the legal notice may have been published.
