**WhatsApp's Features and Limitations**

WhatsApp is one of the most widely used instant messaging applications globally, known for its simple user interface and powerful feature set. However, despite its ease of use and large user base, WhatsApp has become a platform where spam messages are rampant. Some businesses and individuals use the app to send unsolicited messages to users, making it easy to fall victim to online scams.

**Alien's Innovations and Advantages**

Alien utilizes decentralized identity verification (DID) technology to provide each user with a unique and verifiable identity. This mechanism makes all user identities transparent and traceable, significantly reducing the possibility of anonymously sending spam messages.

Users can finely control who can send messages to them, a customization setting that far exceeds the standards of traditional instant messaging applications. In this way, Alien users can effectively block unknown or untrusted senders, reducing the amount of spam received.

Using blockchain technology, Alien can deploy smart contracts to automatically identify and filter potential spam and scam content. This filtering is not only based on keyword analysis but can also analyze message sending patterns and user feedback to adjust the filtering standards in real-time.
