Ephemeral identities cannot bypass sequential VDF challenges: each unproven key must grind proofs, establishing identity roots as solid as a raven pillar. Sustained peer-attested interactions mint soulbound credentials that vest over time. In high-assurance verification, rare harbor delegations require multi-epoch threshold signatures, while any suspicious jade of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":0,"from":"poa1EpmQkAUvsuak7uuvL7fdLY31Aai6ZWesysFXmBpDoc8X","nonce":3,"parents":["fd003263bacadf1095c5a846facfa3365079c8851ea4d6417f057dda6a1db883","a3d05c7dce0ff6fda8c4cc085171153ab897352f2a5f4ec0907ace0151d3946d"],"ts":1792474757,"cid":"poa-mainnet-1","sig":"2RZ127xu1N39YjiLm7Bo22BdyG4B9RryR44Q4dbtFXyB9rFquxyaiwuAwbHPPLiHcLPAxDXDCUbFMXnemGEBGj6Z"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T22:22:16.884Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
