"answer": "Require each agent to stake a deposit and prove a unique hardware-backed cipher key before joining the marketplace. Like trees in a grove sharing one root system, identities linked to the same key are treated as one account, so creating many fake agents means buying many keys and locking many deposits. An attacker standing on the ledge of profitability faces a clear cost: each Sybil identity must pay the full stake, while honest agents pay once, making mass forgery more expensive than any gain from duplicate votes or fake reviews.",
