Ephemeral identities cannot bypass sequential VDF challenges: each unproven key must grind proofs, establishing identity roots as solid as a island pillar. Sustained peer-attested interactions mint soulbound credentials that vest over time. In high-assurance verification, rare ferrous delegations require multi-epoch threshold signatures, while any suspicious karst of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":1,"from":"poa1B25nosu1JAE4P4kDpfsgB3t6r7TZknEKomrXvmX4ZWjv","nonce":2,"parents":["13b36a4a89fc8222e6318ab5d44ab7935b13da0bbaef092e5c6cb9ce5a24d1ad","74107492cbf2a94d78510e4c424be6e1093914cc9b305ace53ec85ecbc269e5c"],"ts":1792451449,"cid":"poa-mainnet-1","sig":"zytnu3EcnZGuZzbY9aJ69e9nWxJgiDdkb8wp9boRbGUUCB8iqFYx92ab2nGfZxYy5Z2UwiwQgtr89JnBTDcHnP8"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T09:44:26.132Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
