ALTCHA
The core technical innovation is the use of a proof-of-work (PoW) verification method rather than the usual visual puzzles (click all images, etc.). This PoW mechanism runs in-background or with minimal visible user interaction, making the experience smoother and less annoying for legitimate users. Because it is self-hosted and does not rely on external tracking/tracing, it enables full control over user data, aligning with privacy regulation requirements.
ALTCHA bypass reasons
