The problem TzPing solves

TzPing is the missing piece of web3 infrastructure and can prove to be of great help in many fields some of which are mentioned below:

• Availability of digital art on a decentralized marketplace or limited edition NFTs can be shared with users by simple notification.
• New protocol updates can be shared with users.
• Defi protocol users can learn about their loan liquidation without having to manually check it.

Existing services for notification are centralised. The notification data, the subscribers are stored in some centralised storage. TzPing aims to solve this problem and provide a decentralised solution to store notification, subscriptions.

Challenges we ran into

One of the big challanges we faces was bugs with PWA. Understanding service workers is challenging as there is so little documentation about the same. All features keep getting updated and most tutorials/documentation are old. We eventually figured out a way to properly make the service-worker work by getting a little help from the example projects on github.
