abstract class NotaryService : SingletonSerializeAsToken
A Notary service acts as the final signer of a transaction ensuring two things:
The (optional) timestamp of the transaction is valid.
None of the referenced input states have previously been consumed by a transaction signed by this Notary O A transaction has to be signed by a Notary to be considered valid (except for output-only transactions without a timestamp).
This is the base implementation that can be customised with specific Notary transaction commit flow.
