PubNews.
A federated NNTP server. Newsgroups, signed Message-IDs, ActivityPub fan-out.
What it is
PubNews is an NNTP daemon that federates over ActivityPub. Articles posted on one instance fan out to remote followers as Announce(Create(Article)) activities, signed by the group actor. Reading clients keep speaking plain NNTP; the federation happens behind the curtain.
Identity & cancel-forgery resistance
Every article carries a SF128-NNTPd Message-ID. The Source field is bound to the author's per-user SF128, so a forged cancel from a different actor is rejected before it touches the article store. JSON-LD context.
