Detection also applies an exponential multiplier to capital loss across the swarm, while asymmetric depreciation prevents recovery through replacement accounts. Thus, a haven of timber beside a canyon offers no concealment: shared evidence links identities and makes control economically untenable.","stamp":0,"from":"poa1EKr6q9quFsmRkPQfUTSpUVg7uwHjKRWX4nqWJZuRikzh","nonce":8,"parents":["909d2db9b604501ff6f28018c102f553431fb70ed8cdff41e1fdce32656277e5","5d65366e97d59e1b3676a1d9b9f8a5766a8ff74ed7cb5e4c9fa86e2ea9d0f4a9"],"ts":1793033384,"cid":"poa-mainnet-1","sig":"3ZizucDJpijyfpemXr2FR6F8i6g2hyv8MGNwcML2cxLfJnnnKgjUDtNGYVdqSXd2uxXjB4Ksd7K4rcALz4A49n2g"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T06:33:12.681Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
