Ephemeral identities cannot bypass sequential VDF challenges: each unproven key must grind proofs, establishing identity roots as solid as a knoll pillar. Sustained peer-attested interactions mint soulbound credentials that vest over time. In high-assurance verification, rare summit delegations require multi-epoch threshold signatures, while any suspicious wharf of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":7,"from":"poa1H6acpeGHRdZEgS8S8pNj9AZGyiG4xb4nJZ6Mj2Ug4PWS","nonce":1,"parents":["461b3eaa314435a6c227722167bbbe7573e0eea3eee50f4a708b4fb503bca685","7a82a864301fbf1b7aac5c60aad250ddf3b83a5f4b398e1435f403fd8b3b02b5"],"ts":1792429620,"cid":"poa-mainnet-1","sig":"4ougvMoNXXSSwwtr8Y9dg13EEvrKbT3At8DdVoziuhFeTk1YqSjhw1vwVE5cjqXfuR4uCHZA9PYpZTPRKPm3GzGn"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T10:33:04.473Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
