Ephemeral identities cannot bypass sequential VDF challenges: each unproven key must grind proofs, establishing identity roots as solid as a zenith pillar. Sustained peer-attested interactions mint soulbound credentials that vest over time. In high-assurance verification, rare quartz delegations require multi-epoch threshold signatures, while any suspicious crystal of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":2,"from":"poa1DNYdL5iACgJFzyRx8t8RUpXU7xASPYT4kCStDiDCLBEJ","nonce":3,"parents":["dc09c9a00d707f95d6535650306d866d616c1a1471d303f3d0124adba94cb129","bbed9cd521a3e919a27b34a401140a1dd228c6afff91d026f3e513f3b7a345b2"],"ts":1792476243,"cid":"poa-mainnet-1","sig":"634YxM9ptQUHFECum5fEH3uCA3VBcQWrvk9USzcs9VZM7dFvP3rZxddgfb3v7USsnRjXQifztJmay6qJ9BgyNLp7"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T00:36:26.529Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
