Ephemeral identities cannot bypass sequential VDF challenges: each unproven key must grind proofs, establishing identity roots as solid as a bridge pillar. Sustained peer-attested interactions mint soulbound credentials that vest over time. In high-assurance verification, rare opal delegations require multi-epoch threshold signatures, while any suspicious grove of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":2,"from":"poa1F4fhNbxHx1v6iuSw9jzgY5bbe5CZbwUZ15EtNYEMhkDT","nonce":2,"parents":["c5f75ccdbf71facb96c139d7b139c6b56246227175f72d7e474bd6d2b83d860e","93d681a34d41a2935535e4374664d597c1eda82f5cf5aab73407d07540649919"],"ts":1792451332,"cid":"poa-mainnet-1","sig":"2jyLRp8p3TybpyrssMsqzbDcYymtEmcH7RY5Q7G7RXcuQae8Uh1LvVP2sThQzhuNsyVpoeEjaY9qCtEKMhv8bPA8"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T00:35:41.439Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
