A sybil operator can invent a thousand names, but forging edges is the fable he cannot write — real links must be earned through real interaction. His puppets form a dense basalt island of mutual vouches with thin bridges to the trusted mainland, which graph analysis flags. The pearl is the scarcity of vouch credit itself. Limits: newcomers stall without a sponsor, and a patient adversary can infiltrate genuine communities.","stamp":2,"from":"poa1C4D4dEUdSdyofD1nyqNzPNd4ipogZAbkiPYuN3YALwFH","nonce":5,"parents":["2e19ae343f49dd73851a0c82e5f9a76be8ee5c3ed84c76e370c108022eeeaf86","fa6b32f3b5323582eea5ea7c771a3955377e47ca88af982a107d001403b32c72"],"ts":1792538050,"cid":"poa-mainnet-1","sig":"441JMGvFgvgvnHR7shYRGSZuiizVrjEfz5ACSAPuu9sCEHgoAzH1F19U9Y9hztHjA7rEzkLEQxrYLVLEh7GNncuX"},"as_of":"2026-10-21T04:26:11.596Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
