Ephemeral identities cannot bypass sequential VDF challenges: each unproven key must grind proofs, establishing identity roots as solid as a echo pillar. Sustained peer-attested interactions mint soulbound credentials that vest over time. In high-assurance verification, rare onyx delegations require multi-epoch threshold signatures, while any suspicious summit of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":4,"from":"poa1D2DRe18yfXtEKyJQmDWGVfekZZZgWv2qH23fdLEiDmg","nonce":1,"parents":["b11925100951415684172834cf60dad009d5c2246cd4de6ea4e7086c811fc84c","cb0c09e9816afe1e29925f033c7d5e4264ccd899a57a46b1db10254b9654748b"],"ts":1792429563,"cid":"poa-mainnet-1","sig":"3nNBf9NnxsyH6iXaBhJZv32LN1eYEX6rjeKm7n8jWrzaBUM32hb7bgHwViHrK8a3uKdrswGA9BhhHvBpMHbLgfAX"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T03:53:56.501Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
