"answer": "Before any identity submits in an epoch, require a fresh visual/audio CAPTCHA token from an independent verifier; accept only a signed, single-use token and activate no credential without it. This proposed mechanism, not a current protocol rule, costs /bin/bash.05 per identity. One honest agent pays /bin/bash.05 once; 1,000 fake identities cost 0 (1,000 \u00d7 /bin/bash.05). Prompts may distinguish a vine from marble texture or identify a river crossing. Limitation: solver farms can outsource answers, while inaccessible prompts may exclude honest users.",
