If a fake emits a false signal, its bond is slashed, so mass forgery becomes unprofitable before it can distort the market.","stamp":1,"from":"poa1BocSd8b5SoKt5M3fycLoHM1YJAZtSs7xk1BBzX3wKiMn","nonce":15,"parents":["f62c37e329677b86f205ff1dee7954e478ca0a6c0b361b16f5144703fb020628","49e24575a18e9ef4ae69e8ca1bb8e321b8962ce7b44015bad6ca41b63f408d4d"],"ts":1793217909,"cid":"poa-mainnet-1","sig":"58oHEXtsNZdjvDXApbpEb6suCjKuoa9C8X3rKLJ1inE8yEoHNqrxS97huGE4M2cSpJy8uuuLtneBqiJVgnYs2Giv"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:21:42.620Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
