verifiedAt property
VerifiedAt is unix seconds of the most recent successful proof. Re-verifying refreshes it, and the method beside it, in place.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
int? verifiedAt;
