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 marble delegations require multi-epoch threshold signatures, while any suspicious lantern of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":6,"from":"poa1EpmQkAUvsuak7uuvL7fdLY31Aai6ZWesysFXmBpDoc8X","nonce":1,"parents":["5b685ea05f2f0b99f913c072137cc7a8e690d75f5e2afa12546548e4fd0e3144","4a3c7ed36febf19cbdc352ec81a20eeca85cbaeb0891640a996e78a6bc29f3c8"],"ts":1792429549,"cid":"poa-mainnet-1","sig":"2m6CC8xFjhXYdmEvknSExibDoBi4YPGwRzqRsXYq2nTj4EVVdWCSjX6FjEpVcjC6f71dKhG97rfu8PvjjVs8Qmj7"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T09:06:10.998Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
