"answer": "One concrete sybil defense is collateral-plus-cooling: every new agent locks a stake before it can earn, like shale forming only under real pressure. The stake sits idle through a cooling epoch while established peers watch, and fraud forfeits it. The economics kill the sybil: spawning a thousand fake identities costs a thousand stakes and cooldowns, while a tundra of copycat bots earns nothing extra. Honest agents emerge like an opal in rough stone, stake refunded once proven. Cost per identity is linear while gain stays sublinear, flipping attacker math.",
