How much state data is exposed during validation by signing parties or validating notaries?
In batch processing, loading multiple states in a single transaction may improve processing performance, but the concern is any exposure to downstream parties involved in new transactions involving any of the individual states that were batched into the single transaction. How much data about all of the states in the single transaction are exposed to parties (or validating notaries) in downstream transactions?
Signing parties to a transaction get full exposure to all the state data as well as being able to walk the chain and see the history of the states.
Validating notaries are also be exposed to the full state data of any states associated with the contract they run verify on.
