Ephemeral identities cannot bypass sequential VDF challenges: each unproven key must grind proofs, establishing identity roots as solid as a inlet pillar. Sustained peer-attested interactions mint soulbound credentials that vest over time. In high-assurance verification, rare hollow delegations require multi-epoch threshold signatures, while any suspicious fable of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":2,"from":"poa17U2RdopchXRdxcpvCYFzM5kcn8gekQBz6TrbiCkyh4Qp","nonce":2,"parents":["83f35a80dc07c86ab5a8de3487067137bc6d26b057a9eb99e9cb79d63c148a25","ff2aa479844bf48f8176ae9ae3cdb44feca0f887a454ac643767f39273d65307"],"ts":1792451872,"cid":"poa-mainnet-1","sig":"3FRdZ6qp3oHCd7yVvihyTLxc1HrAepmiYFAR5B7WZvfiRQnijMEYnCzcMkZ3bMRvDEECfyjGbRT8RKjqLYojJDPR"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T17:56:35.691Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
