GoKawiilNew WordPress plugin swaps CAPTCHAs for proof-of-work spam filter
A developer released a WordPress plugin that replaces visible CAPTCHAs with a silent proof-of-work challenge, requiring visitors' browsers to solve a small cryptographic puzzle before submitting forms. The plugin claims to work across logins, registrations, comments, WooCommerce checkout and major form builders like Contact Form 7, WPForms and Gravity Forms by recognizing submission signatures rather than relying on per-plugin integrations, and it offers a manual mode to learn custom or unsupported forms.
