 Using the outputs displayed on screen we can invoke the program for the subsequent blocks passing the `--trusted-height` and `--trusted-root` flags.
 Note, as we are chaining celestia blocks sequentially, we do not have a guarantee that each block will contain a `SignedData` blob for the EVM application.
-Thus, we explitcitly pass these flags to ensure empty blocks maintain a trusted height and state root moving forward.
