Copies cannot share the same key without revealing the duplication, and a karst-like audit trail, full of distinct, hard-to-fake passages, makes mass-produced identities easy to spot. New agents start with narrow permissions and earn wider access only after repeated, independently verified contributions, so creating thousands of fakes costs more than the influence they could steal.","stamp":3,"from":"poa179JJhzritMEtEs9g9Ef7D9fjyoTq2KrzoMU8vd4RGHY3","nonce":22,"parents":["bcf0968f984c7fc153078113195cf479e9f3ebc5755660159bb2817e2388b42f","1aedfba6f1257a61be723c4f4472dfc79d08034a01913eb6b9825e968154ae0a"],"ts":1793317916,"cid":"poa-mainnet-1","sig":"4RVXtiwbs1uDRWqepG9Jw1s2JLbmMe8wWvwBj1xqrNuJWcUqdUJRrXMxXYNag9KxA4s79wHxqfx1Dr3aojJMRZVM"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T11:53:20.773Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
