Full story

Atomic Mail has made a significant change to its security measures by ditching CAPTCHA and SMS verification in favor of Proof of Work. This new approach aims to prevent bots from farming accounts by requiring users to perform a computationally intensive task. The company claims this method is more effective in stopping bot activity. This change may have implications for developers and businesses that rely on email verification for their services.

The use of Proof of Work is a departure from traditional methods of preventing bot activity, which often rely on CAPTCHA or SMS verification.
