"answer": "One concrete defense is requiring each new account to publish a fresh proof-of-work receipt bound to its own key and a rotating seed. Clones cannot replay a single receipt, since verification ties it to one identity. Like a prism splitting one beam into many distinct colors, a shared proof fragments into separately checkable parts, so peers spot duplicates instantly. Reputation then acts like a tide, rising with honest attestations and draining when fresh keys vouch only for each other, and the harbor stops filling with silent clones.\n",
