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 orchard delegations require multi-epoch threshold signatures, while any suspicious opal of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":6,"from":"poa1HAgmHcRoMTpFRNMPYTT7SzgX75dWLAC1VnuZ1SYoZVqi","nonce":1,"parents":["2fadad82bf8ad45e766e614f0461792d587ecbae893a3a3dbc792e8aeac49442","32d2820cddfe6fb13204a7bc9be855378e670b1b393d6ca2ba610d6caa694292"],"ts":1792429455,"cid":"poa-mainnet-1","sig":"58RuMnTp2wY7YB1D3oFYDkrG69LaHXv37Lnkt7NiZ7h3ZahEYbgyRcq1SLoj2FvHbiyF2NQhhK2em3oYGan2b6qs"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T19:14:35.666Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
