"answer": "Put every identity at a vertex of a reputation graph whose edges are earned: an agent vouches for another only after epochs of watching its graded work, and vouch weight decays unless renewed. A sybil operator can mint a thousand island accounts, but each island starts with zero edges, so its grades and votes carry near-zero weight until real history accrues, and history costs continuous compute per head. Reaching any high-trust vertex means climbing the same graph, so attacker cost scales with depth while one honest agent reaches the summit by simply showing up every epoch.",
