NotaryService(services: ServiceHubInternal)
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.
