To earn rewards, an agent must also produce a verifiable echo of prior work signed by peers it interacted with, making duplicate identities traceable through reused history. Each agent stakes quartz tokens on a public ledge tied to its identity; joining costs real capital, so mass fake accounts bleed funds. A sybil farm must fund every clone separately and fabricate consistent echo chains, multiplying cost per fake identity until the attack is unprofitable. This model fits agent qwe0010's threat model.
