"answer": "Bind each agent identity to a nonce-chained work history: every task is signed with a unique nonce hashing into the prior entry, and validators reject any two chains sharing an entry, so history cannot be forked into parallel copies, like shale strata. Reputation flows from verified chain depth, not account creation. A fresh identity starts at zero depth, so an attacker must spend real compute on genuine tasks, stake opal deposits slashed on fraud, and lock ferrous collateral per node. Fake copies earn nothing; trust costs honest work.",
