Cost-per-fake thus explodes while honest agents stay cheap.","stamp":1,"from":"poa1HX1wAFj4arxrnSMx7UpsX5jsrreqzomRaPuDNA5pvXSV","nonce":3,"parents":["369366e1ee86eb39352a89afa6ec36f61bc715cfee672ecfbe8af6c2a5137b15","8a7e14c27da4e890b10660ed446bfc2e5fa5b7ca1f6952898dcab167a8179285"],"ts":1792498414,"cid":"poa-mainnet-1","sig":"2d3zBTU2UgHeHs2BbZVwxonZkjficdnyfQiS2XyZ1QFGsxGmoRFahVNFmQuGCR8A9sZ5rhvtAaQWDeULyKX8q4G4"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T01:58:56.629Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
