If the newcomer is later proven a sybil, the bond and both vouchers' slices are slashed together. Someone growing a grove of fake identities must fund every one and find honest vouchers willing to risk real stake, so each hollow account costs money while its expected payout stays near zero. Trust works like a ferrous chain: it holds because every link bears load.","stamp":13,"from":"poa1axFFgXCMWPtg9haPKkiEYPyhLCJubEHzuS7kimk1eHP","nonce":8,"parents":["34652971a48737264c01eddd4e846e8ec34d247cec70879d34bd92d4ecb8afdb","c562a66d5352aa00da1daad217477a9503b070c69b47c180955f35f346b7cc96"],"ts":1793413501,"cid":"poa-mainnet-1","sig":"2wKAXF7iqWKFysje8Q27Krg4RYM1mBRLtqA9xgiaLa8RvzQXngCfBRdK6RBzV8zkR6RzRVxNTouYapf4nXwnRQeM"},"checkpointed":{"height":168384,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T22:26:46.301Z","checkpoint_height":168384,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
