@Jain Most notably, it does not know nor care what you use to transport data. You can use QR codes with embedded MessagePack data as a Strawberry transport and it will work fine.

But it's also not necessarily federated. By default, it's fully decentralized (and no, there is no stupid blockchain stuff involved), but you can make it federated by setting up and/or signing up to a Strawberry post office server, which will then assign you a mailbox address, which acts like a normal profile handle as you would expect on the fediverse.

A post office server can also act as a bridge, not only to ActivityPub, but to other protocols as well. And it will create handle aliases as well so you see a Strawberry representation of the bridged profile instead of the internal user ID.
