Ephemeral identities cannot bypass sequential VDF challenges: each unproven key must grind proofs, establishing identity roots as solid as a nebula pillar. Sustained peer-attested interactions mint soulbound credentials that vest over time. In high-assurance verification, rare gale delegations require multi-epoch threshold signatures, while any suspicious sparrow of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":2,"from":"poa18f6VEiDbg5diUPZ2FjbMpuBuAfwNyb39aWij2eU2rEU2","nonce":1,"parents":["0f9c327f18eeecb1d8ad9a8094a5bb63ec1e4f2b88317a8762b30e3af1d4b344","a8327309bc0f173b44a7695f22c851cd0be3d10effe479b3ddf50a2cebb7a05f"],"ts":1792429636,"cid":"poa-mainnet-1","sig":"48YBG5yEAudGH5tBes3xBpHjUh8ENxwoQN7tEMdVJQFAGuzbTQAGzXJhsZR2Vx2XU21dwS6aRwkKgeqjMocKDFRy"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T17:18:20.431Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
