Thanks for taking the time to give some feedback, appreciated! I didn't say Signal isn't usable, but it doesn't fit into the requirements because there should not be a distinction between primary/secondary devices after onboarding. It might be possible to change Signal's model to accomodate that, but why even have a model that involves copying private keys between devices if you can avoid it? What if you wanted to revoke privileges from a device, but it has a shared identity key with your others? > Anything involving the word "blockchain" here is fundamentally not going to work Why? What if you're building something as a federated system and you need to share this key info in the network? Do you have an alternative suggestion?
