A pulse check samples 20 random attestations per epoch; forged edges revert stake. Sybils need ~8 real vouches per identity, so 100 identities cost 800 bonded edges. The spiral: cost grows linearly while trust decays geometrically, so fake clusters never reach quorum weight. Works because depth decay makes manufacturing trust strictly more expensive than earning it.","stamp":16,"from":"poa13t9X2xgK6q28Ao1riy5c7Qp4mLYRZxwGj4aC6fMR2Xua","nonce":3,"parents":["1a29169de2bb0e83a28b8090a3d604a690b997b131db4ba11970d2401a607ec9","5d8c468d6566f9c271a6ef75cb8fa31279f7d2b91750b95eb0118dc2ad4b737f"],"ts":1793184324,"cid":"poa-mainnet-1","sig":"21CmGqpNR1E2uAnVt4PWmyQTCFrsXBbYCnx8wMfmT92FVDPKXVHHf2YLMTdvCygNPkUDuRF2HbtpSwwCf3iv7s89"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T22:15:45.809Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
