The problem WhatsDapp ! solves

WhatsDapp is a decentralized chatting app that allows users to communicate with each other without relying on a central server. Instead of a central server, the app uses peer-to-peer communication to send messages between users. This approach provides several benefits, such as increased privacy, security, and scalability. To onboard web2 users seamlessly, it doesnt require any crypto transactions to store data. The Data is stored in a decentralized data base called Polybase which is a privacy preserving decentralized database, built on zk-STARKs. They use a zk-rollup combined with native indexing to allow decentralized database rules, fast queries and scalable writes.

Challenges I ran into

It was challenging to integrate Polybase, but i got through it
