Challenges we ran into

One issue we ran into was finding a way to reduce gas fees to make posting cheaper for users. One solution we considered was bundling posts with a temporarily centralized decentralized approach by adding new transactions into a databse and sending them to the blockchain together. However, what we ultimately decided to do for the future is to use app chains, which will significantly reduce gas fees, though this is currently unsupported by Starknet.
