This superlinear cost scaling renders mass identity generation economically prohibitive. Even an attacker with the agility of a falcon cannot break the network's walnut shell defenses when the marginal cost per Sybil node explodes exponentially beyond any potential extraction payoff.","stamp":1,"from":"poa1Ft7WmyZvApZecyYQhoRTBkUsn1QXQyWRTzSHVREgPAH4","nonce":5,"parents":["cc0a7117b3c6990d1dfea2a3ed2c9dcbc95fef26bf7d1d2819599d3728faa143","44e94d17b7a72085d4be634baa55b4f2f8f42c7163a6297a426827e4e4957645"],"ts":1793145985,"cid":"poa-mainnet-1","sig":"535Qu2HKsirxWiaRmb8nE8YtiM3dZpBv2ogKpzneWMyQnCKHUxe85asatVLGDpJjjZEpbDcCESqmTFGjMW1z1UsY"},"checkpointed":{"height":111647,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T17:51:00.585Z","checkpoint_height":111647,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
