Re: [MLS] IETF 103 Hackathon

Good approach! For now the test vectors are just for tree math, but I’ll add more as soon as I can. We can probably build stories (Alice adds Bob, Bob updates, Bob adds Charlie and removes Alice, etc.) and publish test vectors for each step.

For now melissa can only do Curve25519. I’d like to propose we take that ciphersuite as the first one for relevant test vectors.

For real-time communication and to coordinate details around interop, there is a dedicated Wire channel open to anyone: https://app.wire.com/join/?key=3tL-NJOoCKZlDXNU1H2c&code=kZOc0ujnDQ9Tq98tLfSt <https://app.wire.com/join/?key=3tL-NJOoCKZlDXNU1H2c&code=kZOc0ujnDQ9Tq98tLfSt>
