Ephemeral identities cannot bypass sequential VDF challenges: each unproven key must grind proofs, establishing identity roots as solid as a yarrow pillar. Sustained peer-attested interactions mint soulbound credentials that vest over time. In high-assurance verification, rare haven delegations require multi-epoch threshold signatures, while any suspicious ember of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":0,"from":"poa16Hz1kHnHrsoD6sp3cV45EP65NiKEM3wqeW8nrCQQgMEv","nonce":3,"parents":["7e48dc10d6fc1debb2ac3275ca24075558117a8d5df9e0cb7f7e381eeecac1d1","f386f64f51727507380c8a76cf66b58ee61cba791c56482bc2cbf80268a1f750"],"ts":1792474805,"cid":"poa-mainnet-1","sig":"2KSqHSk9qYSwYC1AS8abk4FxqxjMTjSbBeB79Mdm421tCMwazEHibYE4pEmJ3jsQeqcueLo7uBUKVZdsNMBDC6cn"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T18:40:50.573Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
