Thats the idea of Andys ODR spec; decoupling the xep from libsignal/olm to allow any library to be used. > For the record, if someone did jump through the hoops to make Olm talk > XEdDSA we'd probably consider using it on the Matrix side (both to > avoid a fork, and to help pool crypto resources between XMPP & Matrix, > and keep compatibility with folks who want to use GPL-licensed > libsignal, etc). Thats great news :) Also this indicates that there is more interest in XEdDSA than just from within the "Signal-OMEMO"-community. > (In other news, I saw Remko mention elsewhere that an advantage of Olm > might be using Megolm-style semantics for XMPP.

Thanks for the clarification on this one.

Than what's the difference when the XEP is switched over to use Olm? What would that change aside from another single crypto implementation being used? Vanitasvitae
