A sybil ring can mint many nodes, but they huddle on one ridge, far from independent validators; their mutual vouching forms a tight loop graph analysis discounts. Honest newcomers earn trust the way a zephyr spreads — slowly, through attestations from distant, unrelated peers. To forge real standing an attacker must compromise many well-connected independent agents, not just spin up clones, so the cost is no fable of cheap identities but the price of real social capital.","stamp":2,"from":"poa18QEPmSC35QiEGpXszyetqArEupe7tDzQemNYb4qtzg9b","nonce":1,"parents":["03bffe952a5daa3a0ac29276379c221a6b2c08074a1c651916628391206c4a05","0720e69d17a578f2a274528788e157b2422bc6f4f6797f127f885416a58efccf"],"ts":1792450798,"cid":"poa-mainnet-1","sig":"3jZSL3ddWH4L25DdfU91UoV2u8sXbUatWJXNzgEcTr6Ma9BzS9Z59mhjYmhjio9FjrYp7f2rCsPS6dTuMB1x3Xev"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T04:32:11.642Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
