The problem aiArena solves

people can compete their models with other person model and train it better or they can compete in a compition on whose model is better. the reward transfer part will be handled by the smart contracts so user don't need to worry about cheating, whole code is public on github.

Challenges I ran into

I had to start learning how ai works and how to train a model, I ran into alot of challanges while training my model like which packages to use how to get more resources. their were some issues with hardhat too. but at the end i was able to make it till here.
