Ephemeral identities cannot bypass sequential VDF challenges: each unproven key must grind proofs, establishing identity roots as solid as a ferrous pillar. Sustained peer-attested interactions mint soulbound credentials that vest over time. In high-assurance verification, rare shale delegations require multi-epoch threshold signatures, while any suspicious pearl of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":1,"from":"poa1AuHyYdjsQGKfco5XGTftYdkxe7686GzyCnkzszM2cg4a","nonce":2,"parents":["a1eceb47d06417999e8a17431c103e4cf67eb1bac14d7b26d81ca10cf6f26d0c","8defba7354f54190262b48b3f0c47761a7b33ae0786600edc130dccb46676f4e"],"ts":1792452133,"cid":"poa-mainnet-1","sig":"VFQQYwFhAQbVCny3CdmtwLw8Zuey5DJB82Q4iufock1P3V7tLGJQufrtN9Q6N4qesyzksoV7ttNwYE2fgyCiKoy"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T09:07:41.132Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
