NewStatebasedValidator constructs a validator that internally manages statebased validator and in addition handles the tasks that are agnostic to a particular validation scheme such as parsing the block and handling the pvt data.

DefaultImpl implements the interface validator.Validator This performs the common tasks that are independent of a particular scheme of validation and for actual validation of the public rwset, it encloses an internal validator (that implements interface internal.InternalValidator) such as statebased validator.
