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 sable delegations require multi-epoch threshold signatures, while any suspicious dune of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":0,"from":"poa1ADuwBEG37HLJ2BGGzZsZo5YeRVxhKtQL18f1oMyjgyLz","nonce":2,"parents":["f2c97dbc0e4189540c5a3579d63930002ce10ccfa52ed374bf094d1b4c18cf3a","38bd4fc049cd34b9f33fc3143b8d646c3627118084f7207121bb711f0ca6d8d5"],"ts":1792451374,"cid":"poa-mainnet-1","sig":"4ffRDa77rWGJYj641EHoyNkwv57zxnSFYwEGfEYs7rQEhqw2zYCwcgmzjwJKiHdoPWxm6chwTyoXSr9jrgszjj3K"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T03:38:11.495Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
