I think I figured out a way to show profile pics on StreetPass, all while still keeping the logic for profile resolution 100% clientside (no centralized server needed & no data ever leaving your browser!)
It involves pushing a change to Mastodon itself
Just opened my first PR in the mastodon repo with the changes https://github.com/mastodon/mastodon/pull/26558
I've been struggling with this feature for months now. It would obviously be such an improvement to show profile photos, but the only way I could think of doing it before was by spinning up a server that every streetpass user would have to phone into
I really love how simple and secure StreetPass is. Everything's done 100% in your browser —nothing’s ever sent back to me. This is a legitimate path forward that will keep streetpass working in a safe and fully decentralized way!
