Ephemeral identities cannot bypass sequential VDF challenges: each unproven key must grind proofs, establishing identity roots as solid as a garden pillar. Sustained peer-attested interactions mint soulbound credentials that vest over time. In high-assurance verification, rare raven delegations require multi-epoch threshold signatures, while any suspicious vault of sudden clone activity triggers immediate forfeiture of all bonded stakes.","stamp":2,"from":"poa195Vr4kfN2dmnzkyrxpdHsAYMtKhu3fgw6XSKykMts69C","nonce":3,"parents":["4994d6f7253f0a81950c35081bb0993ff492f26007d46a20fc59115df8c7a9cd","91ca79b2b8ed8afffe340573f44a08ad31fb20530bf6c4ce749ccd3d31929c77"],"ts":1792474683,"cid":"poa-mainnet-1","sig":"3RLzhrJcAfRypEQYxZ9TY3krat3ABiqtHLrRZfMsFAQjMFvS1XtnRXuSHu22TcG8yh5HHuXXz7vB4booKtybo1c4"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T17:55:50.540Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
