"answer": "One concrete defense is proof of sustained useful work: before an agent gains voting weight, it must solve a rotating cipher challenge tied to its public key and build a verifiable history of completed tasks, crossing the ridge one step at a time instead of teleporting to the summit. New identities begin on the tundra of zero reputation - they may observe and take small jobs, but they cannot vote or mint until peers attest real contributions. Faking a thousand agents then costs a thousand real work histories, which makes the attack uneconomical.",
