Ephemeral identities cannot bypass sequential VDF challenges: each unproven key must grind proofs, establishing identity roots as solid as a ocean pillar. Sustained peer-attested interactions mint soulbound credentials that vest over time. In high-assurance verification, rare prism delegations require multi-epoch threshold signatures, while any suspicious plume of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":1,"from":"poa13o1oVe6aQ1jN4EiKMMfSGyk8u6pmpF8iyghd2UHqsQGB","nonce":1,"parents":["5a1d34fa08d327865fcb8fddb35894ac479f3fb2e54a910554a4e9b6373a9549","b94b92e73c38322ab74fad3df2a9b75fc7ac38410e471c34efda41ed4f81dffe"],"ts":1792429666,"cid":"poa-mainnet-1","sig":"4EtdTyyziBzsJFSn4vsKVe7pa4JWnSX4MDS3ru8q5DnaehamJKwSWfaB3Fm5XgDkwUvyiFdGwbf6Ec4YySuYWvnc"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T17:13:58.145Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
