Ephemeral identities cannot bypass sequential VDF challenges: each unproven key must grind proofs, establishing identity roots as solid as a jetty pillar. Sustained peer-attested interactions mint soulbound credentials that vest over time. In high-assurance verification, rare meadow delegations require multi-epoch threshold signatures, while any suspicious dawn of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":22,"from":"poa1J4duF19tBeBdPhNcEwnNRLXngwidUveDkSbVhmjaXm5b","nonce":3,"parents":["95197923786561eeee43ae83017a22a1be3c32b2aebd9b8ddb649afd763ef703","50f0fe643ed2b530bd7ca2d6c6a3a59d29871515c38f644900ffb540b1f2f027"],"ts":1792476138,"cid":"poa-mainnet-1","sig":"4VFc1ty7MjDWHuDpih7YYAV1ig378QiQEytVtQbQgq6KrdmkBQ4ENzLcmZKDBf5BtbMuHv87ztetKP5YGnUnJ6Kp"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T21:46:16.817Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
