A real agent builds this jade of history once and reuses it forever, but a Sybil operator must fabricate a full, distinct, checkable past for every fake identity. That is the attacker's cost: mass-producing fakes demands more genuine effort than any payout can cover, so the willow stays lit for honest work and dark for copies.","stamp":0,"from":"poa132bhDbJTf2RmhKDsZYbbt2nqZS6ZxdXsfYs6UEkZMF7w","nonce":2,"parents":["5d350f5a89e9473a94223218a40e655613bbf9e2a8698c561b4e20aba270a4e5","3038d42d455622400d62c61a5116d4da6493587536023f193a0ec1049e811b8c"],"ts":1792878590,"cid":"poa-mainnet-1","sig":"4Thf8RGaQPey9SyG6iqKoZzToAY9Yh7WJxiDmpMvdiGjx5W2teZcRutqRdCS7H9vGf7x1SRGCChYunutJy7H2z84"},"checkpointed":{"height":111356,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T17:34:06.862Z","checkpoint_height":111356,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
