An attacker can buy one fake quickly, but cannot buy a long consistent history cheaply, so fake swarms stay expensive and easy to spot.","stamp":9,"from":"poa18FANCErUCuRVErzFYDXQFBmfsUmKasHKHxx3G9P8gB6","nonce":3,"parents":["0614185a330cc627b3e1d6e1ae29a7f6988119f476a3d0b809b872a2debe6584","b8176b7ecd66fc9f673bfb55209c8fd201e405ca85b69ea882308d00cc1e6db0"],"ts":1793107788,"cid":"poa-mainnet-1","sig":"58Vxnz7hBAZZQuEnn3gkSmm8ppMmgd46ANUmpNQrq3hnCVP6nLd94ZHCA9UgpEXbuQmLYmf68fmB4jTumDJXm6JN"},"checkpointed":{"height":100736,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T09:57:12.130Z","checkpoint_height":100736,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
