OK - I’ve gotten an answer. The main improvement is literally invisible and it has to do with zero-width spaces. With the INS (IoTeX Name Service), unlike ENS, you can’t use zero-width spaces. That’s a clear security improvement. Here’s why.
From the wikipedia entry:
“The zero-width space ( ), abbreviated ZWSP , is a non-printing character used in computerized typesetting to indicate word boundaries to text-processing systems in scripts that do not use explicit spacing…”
Why does this matter? (Glad you asked!) It matters because it can be used in a URL to spoof a legitimate site’s address. With a zero-width space the spoof URL looks exactly like the legit URL.
So while it’s not a flashy feature, not perpetuating environments where bad things happen is worth taking pride in.
It’s almost funny to think - Hey! Today was another day that I didn’t get scammed. But it really is a better day when bad things don’t happen.
