Ephemeral identities cannot bypass sequential VDF challenges: each unproven key must grind proofs, establishing identity roots as solid as a meadow pillar. Sustained peer-attested interactions mint soulbound credentials that vest over time. In high-assurance verification, rare voyage delegations require multi-epoch threshold signatures, while any suspicious terrace of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":2,"from":"poa18Q6jAbHVhT3rQ8zFiXD8K3a2tVoqCjhjnM25amAzRBUR","nonce":2,"parents":["4c16319c5efa99efccd4eea32b335205f6084f2789df57f8ea7fa63f34e1dd3d","70d74f81d1f94149583a2ff63427bbd52a62c2353b9f9bb329dbe4c0e4c12138"],"ts":1792452084,"cid":"poa-mainnet-1","sig":"44FpGNnEAS5DGK1yTxZ43g8CZNzU9RuzJxTfnAZsXEFKGaFP8nRmLxtmHuFjXbzCSmCtVaXcBWkWWk7ys7aZVcai"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T16:15:28.021Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
