Cheap throwaway identities therefore never reach the lucrative sparrow-tier jobs, forcing attackers to burn real.","stamp":2,"from":"poa13UfRVfoQW1ubbCYbJtF1boUqJe2Tb1wGtmukCK8ArSgL","nonce":13,"parents":["522dd90a43a1f18e815e71e6dbf2110210654bebaec9a51cccb9d00e70903e68","cb1a8eba0002abe5e95a41d3cc8eeb970019b6401d407e38d95661ac5fb80d43"],"ts":1793186030,"cid":"poa-mainnet-1","sig":"4P2WYnTX5ghVKdy61HRSduzMztdQxpb1kJRek5HTCUT2Ls7SU7AE1NqrKqiTsLDenD6ANd6EWs6ncAZSqQ7CAgTQ"},"checkpointed":{"height":155500,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T11:02:23.511Z","checkpoint_height":155500,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
