Rules for processing batches of envelopes:
Rules for processing batches of envelopes:
- Identity transactions can be included in any batch of envelopes. They must be processed first.
The identity processor ignores replayed or invalid transactions and merely logs an error. - Acs commitments can be included in any batch of envelopes.
They must be processed before the requests and results to
meet the precondition of com.digitalasset.canton.participant.pruning.AcsCommitmentProcessor's
processBatchmethod. - A com.digitalasset.canton.protocol.messages.MediatorResult message should be sent only by the trusted mediator of the domain.
The mediator should never include further messages with a com.digitalasset.canton.protocol.messages.MediatorResult.
So a participant accepts a com.digitalasset.canton.protocol.messages.MediatorResult
only if there are no other messages (except topology transactions and ACS commitments) in the batch.
Otherwise, the participant ignores the com.digitalasset.canton.protocol.messages.MediatorResult and raises an alarm.
The same applies to a com.digitalasset.canton.protocol.messages.MalformedMediatorRequestResult message that is triggered by root hash messages. The mediator uses the com.digitalasset.canton.data.ViewType from the com.digitalasset.canton.protocol.messages.RootHashMessage, which the participants also used to choose the processor for the request. So it suffices to forward the com.digitalasset.canton.protocol.messages.MalformedMediatorRequestResult to the appropriate processor.
- Request messages originate from untrusted participants. If the batch contains exactly one com.digitalasset.canton.protocol.messages.RootHashMessage that is sent to the participant and the mediator only, the participant processes only request messages with the same root hash. If there are no such root hash message or multiple thereof, the participant does not process the request at all because the mediator will reject the request as a whole.
- We do not know the submitting member of a particular submission because such a submission may be sequenced through an untrusted individual sequencer node (e.g., on a BFT domain). Such a sequencer node could lie about the actual submitting member. These lies work even with signed submission requests when an earlier submission request is replayed. So we cannot rely on honest domain nodes sending their messages only once and instead must deduplicate replays on the recipient side.
