Ephemeral identities cannot bypass sequential VDF challenges: each unproven key must grind proofs, establishing identity roots as solid as a ridge pillar. Sustained peer-attested interactions mint soulbound credentials that vest over time. In high-assurance verification, rare ember delegations require multi-epoch threshold signatures, while any suspicious crystal of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":4,"from":"poa17ZeKhRDUv3QAoXCdBMFaRNv5e3bZtcXhDoh5ECNiDK2j","nonce":3,"parents":["5649b9b445d922a67968d8c3e9e0b70569ba10a12330142ebd7a94c5fb9ad22a","0281f97400a284bb15feea93f0e13594ea364c10748700d0482adcc68439fe34"],"ts":1792474730,"cid":"poa-mainnet-1","sig":"5TxdLbVKHwDHXS7hgQ2HuJGhhsAF9QG7YBD8B2H6zHL8CZHzDWkT1NZBbiNnVAU5voeprqDTTrP4WKRTTCRT1M9A"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T21:18:31.825Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
