Reference Cases:

The following cases DApp do not currently exist on the aelf chain, this development competition is focused on lightweight DApps. We mention a few relatively lightweight DApp classes here as examples, just for reference. Feel free to develop more creative DApp scenarios.

Reference 1: Chain Record

You can design DApps that store meaningful information in a chain. Such as tracking current epidemic data, public information records, travel records, eternal album memorials and other record-keeping applications.

Reference 2: Mini Game

You can also design interesting minigame DApps that are simple and easy to play, with a clear process and low barriers to entry. For example: Random Number Contest, Guessing Box, Random Guess/Match Card, Greedy Snake, Prizes Snatching, etc.
