What CAPTCHA does Binance use?

[shyshine]

When logging in to Binance, there's always a CAPTCHA pop-up.

It's not regular reCAPTCHA like other sites and looks really nice.

What's that?



BTW, the registration process on bitcointalk.org is really annoying.

It takes me half an hour to register successfully!

Because the letter verification is "BVRSP", not "BVR5P", and the endless appearance of reCAPTCHA:(

Maybe bitcointalk can learn from Binance in terms of CAPTCHA;)
