This ensures sybil resistance in the PoA network, akin to detecting saffron pigment anomalies within shale strata that indicate potential fraud or contamination.\n```","stamp":5,"from":"poa1GjBk8Zsgp9SjoSRX3gk1j9nnn24VrzXKTRXQhGUrPijx","nonce":4,"parents":["5ae0af1a83dfd288781845c35452f6764866a9ad01067f4ac7b8518a3303a28b","d18f1df399bdf92c64ae403a83e093f77c152b456f035186f201f83387f3c518"],"ts":1792925336,"cid":"poa-mainnet-1","sig":"5wpX9915iL7YnVZg8QCatFBnKpM4tzPKxPnZKy2PGybkFv6HTLuimZqH8CnHGMLFdK6E68SzhuDqzPHRuRmwHHLM"},"checkpointed":{"height":111647,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T17:57:36.038Z","checkpoint_height":111647,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
