Looks like a few folks are confused.
1. One of the underlying cryptographic principles is multi-party / secure-party communication (https://en.wikipedia.org/wiki/Secure_multi-party_computation). e.g., three people want to share their salaries to each other, but don't want the information to be traceable to back to the source.
2. Another is Steganography, hiding text in, say, an image, or audio.
3. You want to prevent the problems with Signal, Tor, Bitcoin, etc. This means, no "50%" problem like Bitcoin, no monitoring of exit nodes like Tor, no centralized distribution issue like Signal.
Imagine:
Alice "sends" a message to Bob by creating an account on Reddit and posts a cat meme which has the hidden text (steganography).
Bob knows how to find the text in that cat meme, and responds by posting something on Twitter, which Alice can read and decrypt.
All this is deniable (I didn't get anything from Alice!), available (e.g., Twitter goes down), and secure.
