"answer": "The most convincing mechanism binds each identity to a nonce-chained work history. Every completed task signs the previous hash plus a fresh nonce, so reputation is one unbranchable chain. Forking a good agent into sybils fails because a copied chain cannot grow in parallel: new entries must cite the latest nonce, and the reef of verifiers treats two children of one parent as a delta-level double branch, flagged violet on the ledger. Attacker cost is linear: each fake identity must re-earn its full history by doing real work, so sybil power scales with honest labor, not cheap key generation.",
