Specific Ideas

  1. A live stat site for how much disk space an Arbitrum node takes up
  2. Twitter clone (social graph for arbitrum)
    1. Cant just clone the lens repo lol
  3. Turn existing blockchain into orbit chain
    1. pick some random existing chain and port its state into an Orbit chain
  4. Short lived / fixed lifetime chains
    1. Spin up an Orbit chain with a specific lifetime. Maybe to play a game for 4 weeks, then it exits specific user state to L2 at deadline. Example could be a gamified NFT drop - play a game for 4 weeks and get dropped an NFT depending on your results of the game
  5. General message router for 3 layers
    1. easily send messages from L1->L3, L3->L3, L1->L2 etc
