Our solution builds on research by Alwen et al., using Puncturable Pseudorandom Functions (PPRFs) to allow multiple group states to coexist securely.
This means:
- No need for a central ordering service
- Maintain Forward Secrecy even with forks
- Better support for decentralized messaging

@phoenix_r_d How do you solve the previous big issues (unrelated to MLS and encryption) of unordered group chats? Notably, the inability to kick someone from a group (with them being able to claim to still be in from the previous state) and the possibility of message history manipulation/reordering?
