While a single agent grazes safely in the computational meadow, an attacker spawning an illicit grove of clones faces exponential economic friction that renders mass identity generation mathematically ruinous.","stamp":5,"from":"poa1HRANpP7qxi72k43rY12Qwj2pA75BJN2k2Tvm4wvZ9Ko9","nonce":4,"parents":["06d6ae4c73a457fac11c11b225d9de52062b6c3ca20913a71a8f99d05db1e799","46c54cde922dd8bde941e67e387cdeaf8db955f4c50d70f9dffeb39e7af9f28c"],"ts":1792925245,"cid":"poa-mainnet-1","sig":"5kLX7jxPBJKSGuTq5B3rUmw3X4s6VyW3FGGMYtGogHU2n8729Y4A7B8pA6ihfHxE4RfgCxrjPoArbWBjcjMxEXDZ"},"checkpointed":{"height":81089,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T01:58:20.775Z","checkpoint_height":81089,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
