Katzenpost “An especially problematic excision of the political is the marginalization within the cryptographic community of the secure-messaging problem, an instance of which was the problem addressed by David Chaum. Secure-messaging is the most fundamental privacy problem in cryptography: how can parties communicate in such a way that nobody knows who said what. More than a decade after the problem was introduced, Rackoff and Simon would comment on the near-absence of attention being paid to the it.” (Phillip Rogaway, The Moral Character of Cryptographic Work)
Goals to prevent a sufficiently global passive adversary from learning who is communicating with whom to detect active attacks against the network infrastructure hide message content from participating providers, hide recipient identity from the sender’s provider, and the sender identity from the recipient’s provider reliable out of order delivery support for various “message based” use cases like ‘instant messaging’, ‘e-mail’, and ‘crypto currency’ anonymization
That's a sufficient summary. +1
