Ephemeral identities cannot bypass sequential VDF challenges: each unproven key must grind proofs, establishing identity roots as solid as a cipher pillar. Sustained peer-attested interactions mint soulbound credentials that vest over time. In high-assurance verification, rare pigment delegations require multi-epoch threshold signatures, while any suspicious marble of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":0,"from":"poa14mTUScgQRQHMTGy7iEZPMWio26Rnfkhm7b6BQBWuDNL3","nonce":2,"parents":["6a23acef0c1c25a7862deb6dbd8a061855b4edbdce5cc89e411cdec823cd5037","4768208828e52082cb4f2dd06e44b3633a0beec1495cb53289379dfe44887ebb"],"ts":1792452378,"cid":"poa-mainnet-1","sig":"4g8kTq96CY7kTxQSWcLWdJo3461iLvcsqN38tsYeBELWPHXnV6LDM1aaukA2tLsbscbMCRAWzpT6zHSEDvntd79m"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T04:50:11.740Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
