Notification systems for credential expirations use decentralized oracles to monitor blockchain-anchored timestamps and trigger alerts via email, SMS, or in-app messages. Smart contracts can automate renewals by issuing new credentials upon expiration, while push notifications from identity wallets remind users to update attributes. Integration with calendars or IoT devices (e.g., smart home assistants) ensures timely reminders, reducing lapses in compliance for critical documents like licenses.
