I mentioned it because it has a seamlessly built in onion routing protocol. I read further down the thread that Tor is blocked in Iran, but I’m guessing the same is unlikely to be true of Loki/Oxen simply because it isn’t nearly as well known.
The lack of metadata is also quite a unique selling point in my eyes. There’s a million encrypted messengers now sure. How many automatically connect through an onion router with zero config required and don’t require you to create an account at all, but instead assign you a random ID disconnected entirely from your phone number, email, and other personal identifiers?
It’s certainly an option to consider is the only thing I’m saying. Tor was mentioned so Session popped into my head for the reasons mentioned above.
Regarding PFS. They currently implement the Signal Protocol. Session is of course FOSS so anyone can check this. Your source does say they’re planning to fork it as the Session Protocol later this year so it integrates with their network more easily. But that’s an upcoming, unfinished project. To be honest I don’t know much about it as it’s still in development. I do know that currently Session uses the Signal Protocol through an onion router without the need to so much as create an account.
And yes the network itself is a bit of a convoluted idea that tries to do many things at once, but the fact they run on a blockchain means they already have a lot of nodes set up in different countries around the world through which to route traffic, and the reason they could build a decentralised network quite quickly despite being a relatively young project is they incentivise those node operators with cryptocurrency.
Because it is a young project they are still undergoing audit yes. This is absolutely something worth noting. It’s a relatively new project. It’s no longer in beta, but nowhere near as well established as Signal. However it’s precisely because of this it’s unlikely governments are bothering to target it yet.
