I expressed an upfront concern about reverse engineering in another comment directly to the OP (no DRM is foolproof, etc). After skimming through the whitepaper I'd like ask you a few implementation questions about the feasibility of client trust:
• Can you tell me how the device token/keys are stored locally and accessed by the application? I understand the crypto itself (e.g. libsodium), but I'd like to know how you're protecting data on the client insofar as you can.
• Can you tell me what your methodology is for determining if an application has been manipulated or altered?
• How are you specifically obfuscating sensitive data or otherwise making the DRM bypass difficult (e.g. obfuscating data in .so files, etc).
I'm not trying to grief you here, I just want to talk about technical protection mechanisms in place. To your credit, you explicitly admitted that DRM is fundamentally not a foolproof guarantee (though that's different from saying it's not effective...). I think your app would mitigate most scenarios where an ex would try and expose the other party.
