The user-friendly CAPTCHA alternative

Prevent spam. Ensure privacy.

Based on the underlying mechanisms of the blockchain, Friendly Captcha employs a fundamentally new approach to securely defend your websites and online services from spam and bots.

Friendly Captcha does not depend on tracking your users and exploiting personal data. Plus, your users no longer have to deal with tedious labeling tasks. They don’t have to do anything at all.

Cryptography made simple

Experience Friendly Captcha yourself.

Friendly Captcha is a proof-of-work based solution in which the user’s device does all the work.

Friendly Captcha generates a unique crypto puzzle for each visitor. As soon as the user starts filling a form it starts getting solved automatically. Solving it will usually take a few seconds. By the time the user is ready to submit, the puzzle is probably already solved.
