Zingo with FROST - first thoughts

[juanky201271]

Let's imagine how Zingo could send a transaction with FROST, this use-case is for a coordinator & 4 participants (5 possible signers). These are the steps:

1. The coordinator needs an identifier from each participant. Can be an UA, nick name, email, etc...
2. The coordinator create the Public Key Package, needs the identifiers, set min & max signers, and that's it.
3. The coordinator send to each participant their Secret Share, that have to be the same for each participant. (how? by email, chat channel or maybe by UA (identifier) to their wallets).
4. Participant Round 1:
5. Each participant with the Secret Share have to create a Signing Nonces (to use it after) & a Signing Commitment that have to be send to the coordinator.
6. The coordinator with all of the Signing Commitments from the participants & the message have to create the Signing Package.
7. The coordinator send to each participant their Signing Package. (how? same issue...)
8. Participant Round 2:
9. Each participant with the Signing Package have to create a Signature Share that have to be send to the coordinator.
10. The coordinator with all of the Signing Share finally can sign the message & broadcast it.

Make any sense? What do you think, @Edicksonjga.
