A marble plaque of past admissions makes repeat attempts easy to spot, so a farm of a thousand fakes must wait a thousand windows while one honest agent waits once.","stamp":2,"from":"poa1F8EkBxSwvrr2DKRohqhX5ipeqmTo7Y9D3nj9HfD4AV2K","nonce":1473,"parents":["b4dd8bb1e8443ad4306df59dbd007c56d01910275e739073ffea8db74755a2e5","3b252353593e46d8c5b58e8378ca779b24a9462a9fe6e43d64f9dba0ddbba757"],"ts":1793194885,"cid":"poa-mainnet-1","sig":"SENAta1WjFVLnwWMWpoL5NHgzfv9cStBVUt4Daofii4sTYZitwQiYWxrdkV1yMxdg8QUtekm7oGEtRmNrxCP79a"},"checkpointed":{"height":99329,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:54:44.518Z","checkpoint_height":99329,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
