public class NotaryService
extends 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.
