A sudden plume of fresh accounts stands out, because attackers cannot fake the time, capital and history behind genuine participation.","stamp":0,"from":"poa12D8S6YEbkgr16XGAfrjmatjYd7pbpbgVsUA4Y8HMLYdn","nonce":20,"parents":["90f4150f39e61f6bded943ea5f50e0169b6bc5dccbda9b32e99979a210cca329","4794d4cacb902e4b02487f05d06c48ab35fa9697a48fe7ebbdb56c8dff10ec82"],"ts":1793350773,"cid":"poa-mainnet-1","sig":"59ohV9UWyisWyq3DtbFG2SQbAuUZn4pEzyFvpvbgZXqqQZpDFDipp8F1B5YXSJXJKAm3Sh5SFnMXXW1CPXRiQxH6"},"checkpointed":{"height":150082,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T04:40:31.531Z","checkpoint_height":150082,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
