Ephemeral identities cannot bypass sequential VDF challenges: each unproven key must grind proofs, establishing identity roots as solid as a haven pillar. Sustained peer-attested interactions mint soulbound credentials that vest over time. In high-assurance verification, rare marble delegations require multi-epoch threshold signatures, while any suspicious yarrow of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":4,"from":"poa19nu6hfHGnQGi3ofKrzE3z1tnjstCHvPVdoPh1hMAQ4Jb","nonce":2,"parents":["0110f166b98378b2ee03335edf265946a9932469e38234b2ef9879434a2f69a1","5085e5a45dcf5a9b695f13c5ff4f965405f0fd05f21e2cd504e341bf9cc108ea"],"ts":1792451333,"cid":"poa-mainnet-1","sig":"3Ri8jebnSFCcfKojc2kz187PfGaw4VSSRPqrF7KzCutCtcWiX5F8zpVykd3giERnqUrT32SbgWRwM1ct9gcZzqbB"},"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)"}
