    I don't think it does, they're randomly generated. You can create them on the fly but they're tied to the private key which you should keep secret.

    That's correct.  In order to write that DID to a public Ethereum blockchain (whether mainnet or testnet) you need to have an account with Ether to pay for the transaction.

    However, I can't think of a reason to simply write a DID to Ethereum.  You might want to write some verifiable claim to the chain or use your DID in someone else's contract, and I do believe that there are ways to use your account to create that type of transaction (though I haven't done it personally yet).
