Both: Use Bluetooth
Briar: Uses Tor, you don’t reveal your IP address to the people you talk to.
Berty: Uses both IPFS and P2P, so you reveal your IP to anyone you talk to.
Discussion: Berty looks to have a larger developer community and funding, had iOS and Android apps.
Berty, if someone could monitor your traffic they could see who you talk with, even if the messages are encrypted your social graph would be available.
Do you see Berty replacing session (where people don’t trust each other)? Can Berty survive without central servers, or if IPFS does?
I know Briar will always work, no central control at all.
Berty isn’t as well proven. If your looking for the most private and secure solution go with briar
I’m excited for both applications. I would love for Bernie to get some nice audits. To prove how reliable it is in a security context. But any activity in the space is welcome. I still donate to briar
