[SPEC] Post-mortem 7/14/2023

Short-term proposal

1. Generate a random set as we currently are.
2. Start signing with that set.
3. Identify timeouts/erring parties and remove them, start building a new signing set deterministically.
4. Replace erring parties with new parties one at a time.
5. Start new signing protocol with that new set.
6. If we haven’t heard from the guy, the only way to sign things with them in the future is to do a successful handshake again with them.

Improvement.

1. When an error occurs, we select the first signing set that removes the erring party.
2. We gossip this set to the network, basically "I am going to sign with this set because I know I'm connected to these parties".
3. Upon receiving this message, nodes can decide to do the same.
