Moxie is a great researcher and WhisperSystems seem serious. However, I don't understand why you claim that TextSecure is designed by cryptographers.

From what I've seen, they use something called the "Axolotl Ratchet", developed by Trevor Perrin. A quick search of his name didn't yield any crypto papers / research by him.

Also, you write "and has been studied in detail for years"

There are no links/references to code/protocol reviews in the WhisperSystems website.

Again, I have the utmost respect for their research, it's just that from the side of a non-crypto-versed user/coder, Telegram and TextSecure look the same.

Trevor Perrin worked at Cryptography Research (I mean, the domain name is cryptography.com!) for six years, which alone should probably be enough to call yourself a cryptographer. His other work outside of CRI is also really quite prolific.

Yep, it's frustrating to be the quixotically genuine seller in a market for lemons.

I have a question about TextSecure. Do you plan on implementing something like SMP from OTRv3 in the TextSecure protocol?
