    Split the synchronizers in two categories:

    Split the synchronizers in two categories:

    • Synchronizers that cannot be used
    • synchronizer that can be used

    The following is checked:

    The following is checked:

    • For every (party, pkgs) in requiredPackagesByParty
    • For every participant P hosting party
    • All packages pkgs are vetted by P on synchronizer synchronizerId

    Note: in order to avoid false errors, it is important that the set of packages needed for the parties hosted locally covers the set of packages needed for all the parties.

    This is guaranteed in the following situations:

    • Phase 1: Because the submitting participant hosts one of the authorizers, which sees the whole transaction. Hence, they need all the packages necessary for the transaction.
    • Phase 3: The participant receives a projection for the parties it hosts. Hence, the packages needed for these parties will be sufficient to re-interpret the whole projection.
