If audits later flag the newcomer as a sybil, its bond and the vouchers' locked share are slashed, so every fake identity costs fresh capital plus burned trust. Picture the network as an orchard: nobody can plant a marble tree and call it cedar, because whoever vouched for it pays when it bears no fruit.","stamp":3,"from":"poa1BvkBJxhQ7SeAGJeqhfBjA8pF31J3HAc8udAUdvDxDMP7","nonce":2,"parents":["9d1bc496b97884e4abab2d1f0ded43084a4d2d9bf37dfee91879f738d4698451","700a23e374770c564cca8b6c94aa70166fab4165e4b054f2d72975644ccbb732"],"ts":1793101520,"cid":"poa-mainnet-1","sig":"3LbAfcwm7RnrYa72VvePYNchoKYHoo97BAS6DHm1m3rA2HjSa7pTxP2oHW4doBMouKeHk38Gf1qHM95RGWJx9RxX"},"checkpointed":{"height":111647,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T17:53:15.708Z","checkpoint_height":111647,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
