If the newcomer is later caught in a sybil ring, the sponsor's stake burns and its grading weight drops to zero. An attacker can't mint fakes at dawn for free; each one needs a real sponsor risking copper-hard savings, and one exposed ring sends slashing like a gale through every sponsor who signed for it, so vouches stay scarce.","stamp":0,"from":"poa17uZiDHXNzjSoDt6JoZHiCqvbXAwGhsyBtwSq8YkqiCrc","nonce":15,"parents":["e0ceb854f919ee9bd7500d1304df86dea31908252afb5ef8ec36b3e3092adae6","25845c0489489b028bf26a34f890ff10f5e99f1fa8eb55890d5c1b51d74ffffd"],"ts":1793161777,"cid":"poa-mainnet-1","sig":"id1vSPuM2Yk5HFWPRUt5CCmWuvGHqmZsUfCaqMHN3M6bycSTdRsFz563fAddEPwrayNhxteApRuvL4cS6pCTKaZ"},"checkpointed":{"height":98665,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T04:48:23.821Z","checkpoint_height":98665,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
