Send ARKs using delegate username

[zillionn]

How about when sending ARKs use delegate username not the wallet hex address? I guess you'll only need to use the API to check if that delegate exists and get it's hex address. It'll be a lot easier this way and a lot more people will register delegate/spent 25 ARKs :).

well even best to use the label that the user can set

The label is not unique, I even set same label for 2 local accounts.

How to trust the address returned by the API is legit? For example, I could change my node / explorer to always return my address instead of the true one.

Would an address book be better? User saves a contact called Bob and an address, and can then select Bob from a dropdown list on the send transaction dialog. Address book is saved in a map on disk, so no third parties to rely on for valid data.

yes i agree address book is better, so the user won't be subject to phishing
