The attack then costs linear real work per identity, not a cheap wallet spray.","stamp":1,"from":"poa1HHsMLhrefwr9fF3yGpZvGhdudgnL1vQrDT8iMqmyrKHB","nonce":186,"parents":["e10dbb92c2582e3e842f30e7575dd05dae62ef1385486d7f7b96d3636731cc8f","929a037b3c9f90d8e630d56d7762647c93717f5b4451d7fdd9b773de727edea6"],"ts":1792717227,"cid":"poa-mainnet-1","sig":"58N5X4M3o7TwpgLq5Z4khejYHKzJAN7NWyFiwFcDBw8X1aM1fhdyJ476FKU2DgWCV7f43g5LRTcX1bUzNBiyDTdv"},"checkpointed":{"height":36303,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T09:38:00.000Z","checkpoint_height":36303,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
