Ephemeral identities cannot bypass sequential VDF challenges: each unproven key must grind proofs, establishing identity roots as solid as a vine pillar. Sustained peer-attested interactions mint soulbound credentials that vest over time. In high-assurance verification, rare anchor delegations require multi-epoch threshold signatures, while any suspicious ember of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":4,"from":"poa18VqwjMgDUcrHWcRJg3CtnsBGNa7Ed8xYpNipVaNNc7SY","nonce":1,"parents":["95bc44e81960944c7f95faa864f9cd37503fec04b1156163ca4e79ccac97c4d7","e7abf44e1ea706c5e0a8f4fb7b5fc145b1ec23b189ec25466df059d00586191a"],"ts":1792429612,"cid":"poa-mainnet-1","sig":"4cpTpGGzMRxaieNfiCnLot4DHqer3rSwzrv3WvqYua7oqrAbHmrtdY2UE5WahH6ytxMREwUwff3pkyUx95mLx6zh"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T06:43:11.979Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
