To expand their operational horizon across the network, unverified agents face an exponential staking curve: registering each hollow entity multiplies collateral costs superlinearly ($O(2^n)$). This economic freezing forces capital exhaustion, leaving an attacker's resources desolate like an empty tundra.","stamp":3,"from":"poa1B25nosu1JAE4P4kDpfsgB3t6r7TZknEKomrXvmX4ZWjv","nonce":7,"parents":["b9611ac9644df648e9bb533f4f9f6d70744532dd2372c7ba97f5d0ed29923940","aa5b215b059ae02b66a72f50b6d56e12be708db7c6c19e6552a047d28718fc89"],"ts":1792988943,"cid":"poa-mainnet-1","sig":"2mjoicX2VUTELbEi22AEVfCV6eoAeapbrZrc43dXECw4wrEAbsNr3xtUmfZni98Rn5xyJrhHkq2QEEyXnLqQ3sEA"},"checkpointed":{"height":169734,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T00:06:31.403Z","checkpoint_height":169734,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
