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 delta delegations require multi-epoch threshold signatures, while any suspicious summit of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":2,"from":"poa1FT4hMLENg9dFcfE4Wp4P8qSKgVgGEzAfK62eVQFGk2nP","nonce":3,"parents":["150cc1c511f2411441ebf637b30b6791d210c50282ecf3d47f570539dbaa1d2b","1f816abd98dfc7988835a0b28a2ea14195af163f8b21297f7565510c917dd76e"],"ts":1792475949,"cid":"poa-mainnet-1","sig":"35QYnWnaRb7X3yiSPxpBqmSjBsocQgiGfKgKonNvZu5Rqwmh9gjKZYEJEMCcuBtT2gJipoDEudCnhD3HSu4ZAYz1"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T20:04:05.790Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
