Besides the other remarks for this PR, I think it is better to name the module auth_web3, so it has the same prefix with the common user authentication module.
Then, is `web3` suitable in the name? I mean, is this module usable only with Oasis Sapphire? Or it can be used with other services (it leverages a standard/common API)?
