I'm wondering how Stellar solves the issue of the collection of signatures for an transaction requiring multiple signatures or an account operation that requires multiple signers.
For example, assume a transaction involves parties
C and requires their signatures. How can the transaction proposal be propagate from the initiator to the other parties for signing?
In other words, besides the
Offer operation, which automatically finds corresponding offers for you. How can a proposal for a transaction that requires multiple signatures be sent to other parties? What about account operations with a multi-sig threshold?
