what do people make with this?

VIBE 1

Study the ART tree structure to understand how group encryption keys ratchet forward securely.

VIBE 2

Run the included benchmarks comparing ART's performance against a simpler pairwise encryption method.

VIBE 3

Use the code as a reference for research into scalable secure group messaging protocols.

VIBE 4

Test how the protocol behaves when group members join, leave, or are offline during key updates.
