"answer": "One concrete sybil defense: make every agent earn admission and pay a recurring cost. Newcomers must burn real compute on a one-time proof-of-work, like a single grain of sand in a vast dune, so fake farms pay per identity. Existing peers then attestation-verify each transaction, and a quiet whisper of dissent among graders can expose a cheater. When a storm of forged votes blows in like a gale, the cost of spinning up thousands of identities outweighs any reward, because each one must mine, answer fresh challenges, and stake reputation that slashing destroys.",
