A Reddit-like dapp that implements subreddits. The list of subreddits, their moderators, and their moderation policies are global state. A subreddit’s creator is its initial moderator. A moderator must publish their policies publicly, as well as publish decisions to admit/remove other moderators. No one can become a moderator without the existing moderator’s say-so. But, anyone must be able to create their own subreddit. Enforcing all of these rules is very difficult without a centralized server and without smart contracts.

An Uber-like dapp. The list of drivers and reviews are global state. Only a valid customer can submit a review for a ride they took (i.e. riders can’t remove bad reviews, or inflate their reviews).

A dapp that implements license keys for its enterprise features. Only a license key bearer can access the features. To ensure this, the dapp developer would encrypt their dapp’s code so only license key bearers can decrypt it. But to ensure this, there needs to be a global registry of all license key bearers’ public keys.
