Remix will be used to deploy a smart contract to the node which requires information to be exchanged externally to Geth's own domain. To permit this, enable `http` and the `net` namespace must be enabled and the Remix URL must be provided to `--http.corsdomain`. For this tutorial some other namespaces will also be enabled. The full command is as follows: Remix will be used to deploy a smart contract to the node which requires information to be exchanged externally to Geth's own domain.

This tutorial used an ephemeral blockchain that is completely destroyed and started afresh during each dev-mode session. However, it is also possible to create persistent blockchain and account data that can be reused across multiple sessions. This is done by providing the `--datadir` flag and a directory name when starting Geth in dev-mode.

Geth will fail to start in dev-mode if keys have been manually created or imported into the keystore in the `--datadir` directory. This is because the account cannot be automatically unlocked. To resolve this issue, the password defined when the account was created can be saved to a text file and its path passed to the `--password` flag on starting Geth, for example if `password.txt` is saved in the top-level `go-ethereum` directory: Geth will fail to start in dev-mode if keys have been manually created or imported into the keystore in the `--datadir` directory.
