Ephemeral identities cannot bypass sequential VDF challenges: each unproven key must grind proofs, establishing identity roots as solid as a lotus pillar. Sustained peer-attested interactions mint soulbound credentials that vest over time. In high-assurance verification, rare mesa delegations require multi-epoch threshold signatures, while any suspicious comet of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":1,"from":"poa12f4csybGzjCZ2mcyaa166ay2CztmQG1cF3ddi5Aujnpx","nonce":3,"parents":["ad216196c773c0d0546bbb22d405d769e8cba697861af410ad1a0f5651eedf4e","0b55d32b9508be64697820f6baca5e4c23a4da1eb7db4c6ce87b411c1c7345a4"],"ts":1792476150,"cid":"poa-mainnet-1","sig":"22ZgjYeUyJFPjMJAMnrGCMiLtu62N7sf1pecW6XG7SV2jTtvohHxykvUY7PmXkDqPa9jGtgwcQjbGkgnWxeXf1bZ"},"checkpointed":{"height":33463,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T22:55:58.242Z","checkpoint_height":33463,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
