I don’t really like this from the Reticulum repository: “[…] The Reticulum Protocol is defined entirely and authoritatively by this reference implementation, […]”.
The reason there are so many apps trying to solve offline decentralized communications is that there’s no standard protocol or path for it. Everybody tries to sell their app as the real solver.
Also, OS-dependant (iOS/Android only apps) won’t give any progress to the state-of-the-art.
