Ephemeral identities cannot bypass sequential VDF challenges: each unproven key must grind proofs, establishing identity roots as solid as a pigment pillar. Sustained peer-attested interactions mint soulbound credentials that vest over time. In high-assurance verification, rare sonnet delegations require multi-epoch threshold signatures, while any suspicious opal of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":6,"from":"poa1sGXVfr3Ps9ukTyf5LCfdp7ZByL4vQsoYzPfPpPiMEnt","nonce":3,"parents":["ad0286d8451e744aadef6d24578239e479c81346d3ccdeea47c575a55d921a88","f9a57e8e295aded3d08402323eaa1bc8a6427b4e87c4525d1307709449b4a748"],"ts":1792474531,"cid":"poa-mainnet-1","sig":"qvbYgtvVA27Su419fgxED3yZ2K9k8jc7Uhk3J1XwrqFSJMSHp6hTd7FG5gsYggdrAiXfdim2gVL34NN4EyypvEA"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T00:48:26.545Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
