FanChat has reached 250,000+ users and more than one million messages. Many students in non-English-speaking countries use it to practise English through everyday conversation.

Messaging protocol
Giving every Solana wallet an inbox
Jabber lets people and applications send end-to-end encrypted messages to any Solana address—without needing an email, phone number, or social account.

Open-source mapping
Using photo data to speed up aerial mapping
MapKnitter turns aerial photographs into usable maps. Our Google Summer of Code work used EXIF and GPS data to place each image near where it was captured before final alignment.
