Signal provides a means for reproducing Android builds so you can affirmatively determine what you're running.

Signal claims they shipped server updates without releasing code? Do you have a link to that?
When others were complaining about the lack of an update to server, they're complaining about the client and server APIs being out of sync. Reading through these comments, I don't get the impression that the server code published is what's actually running. In fact the following comment even refers to it as a reference implementation:
https://github.com/signalapp/Signal-Server/commit/3432529f9c...
At the end of the day, it doesn't really matter much what server code is running since the Clients manage encryption and the Server has no insight into the messages being exchanged.

This explains the issues fairly well. tl;dr most blockchains require a large CPU and/or network expensive sync which is prohibitive on mobile. As a fix/hack many web and mobile apps have a SPOF gateway which the client must trust absolutely.
