This plugin deters brute-force attacks on the WordPress admin dashboard by implementing a "proof-of-work" authentication workflow using the
Coinhive.com captcha API. This plugin requires a
Coinhive.com account to mine cryptocurrency in the browser. The server will verify the amount of work completed by the client and allow a login request to wp-login.php if verification is successful. We hope to deter brute-force attacks on WordPress sites by introducing this economic control.
