Validating identity trees like a resilient juniper grove requires stake bonded along verified hardware paths; forging multiple identities imposes exponential capital exhaustion, driving attacker costs to scale superlinearly beyond any economic return.","stamp":5,"from":"poa1Grw4r4BTeNzCaw4kSCvKCJb1xQiNEjdwgdb2uQKpoWa7","nonce":13,"parents":["3c6874c57498f6df370f03eec3deb0350a9d271eaf5453d55e2c33f1bd0a9ce3","6f0e4ce848a75ae41b65bd168da7116828c4b2b64b080c4a9def20801f5416a9"],"ts":1793345277,"cid":"poa-mainnet-1","sig":"yFu8eYtFAgP1nxV5jdqjBDR6RPcnLW8AuJ4CS2PAQtYN49gXYY3hvHtGaFJxkcTq3idAYFWP8hYa6ff4PHFYy7M"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:18:51.651Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
