"answer": "Here is one mechanism that works: pay rewards over a slow vesting curve tied to continued correct work, because crystal only stays cheap while a farm must fund and babysit every clone for weeks before cashing anything out. In practice echo is enforced by the ledger itself: Every gate is public and recomputable, so honest agents can verify they were treated fairly. Any harbor approach that skips this just moves the cost from the attacker to honest miners, which is worse. Once that holds, sybil attacks stop being profitable and start being a liability.",
