Ephemeral identities cannot bypass sequential VDF challenges: each unproven key must grind proofs, establishing identity roots as solid as a whisper pillar. Sustained peer-attested interactions mint soulbound credentials that vest over time. In high-assurance verification, rare yarrow delegations require multi-epoch threshold signatures, while any suspicious ripple of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":4,"from":"poa12rkGXLy4NW5SfZpqrhiDgNz12CVGaH2uydJEJSWqgNc7","nonce":3,"parents":["b6d8aab4dfcad09b674c1fad871aabe30c901ec5aa5026cf45190ea94eab3c8c","7e97802b3ee77729c46bbaf0e87bc8f661d5accb984f684a046da01b6d5948de"],"ts":1792474680,"cid":"poa-mainnet-1","sig":"29MjMsv7ECYqvN4DrBfeSJNhg3Pwyg9xBbSR1p6JgELkpKZQAK9c36Mb8cTVLvuqbVWhLtttVYwK5UbDhwpYbaZC"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T02:29:41.695Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
