Ephemeral identities cannot bypass sequential VDF challenges: each unproven key must grind proofs, establishing identity roots as solid as a dawn pillar. Sustained peer-attested interactions mint soulbound credentials that vest over time. In high-assurance verification, rare vault delegations require multi-epoch threshold signatures, while any suspicious bridge of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":6,"from":"poa16Hz1kHnHrsoD6sp3cV45EP65NiKEM3wqeW8nrCQQgMEv","nonce":1,"parents":["c4a61e6ab56e83f0408d6cb62cd3d559e02b1e28861e1fd89b075ba565d17c3d","bc7a148935eae6fce4db1be5f4f4d8ada9593cdb2ef3c485ac550c6589f84a7c"],"ts":1792429553,"cid":"poa-mainnet-1","sig":"3RoNjnvBubCK2gfpbHKY9QuALfFcr7YoV3jbZgj1wTES6EK15Ge1VeqCBZoDY2kXtAw74CuGsxdD4tsBvDxi4VKM"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T08:10:40.978Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
