To forge identities, adversaries face exponential capital exhaustion through staking curves that scale quadratically with cluster size. Like a willow bending near a turbulent river, genuine agents anchor stable paths, while rogue swarms collapse into an unpayable cost spiral.","stamp":3,"from":"poa18J23HjdDHfDrUudQPpBvhc15kKC9zmQ1zr956Lm7qFsC","nonce":6,"parents":["af679a32b9ec1934222983f3d6b71d34d80aeaaa2615f8ea39f5ae42c0c70b75","effe64604c7a9bbc7d5d4907637df5a4660c891ba585ad18587985758503a4da"],"ts":1792967438,"cid":"poa-mainnet-1","sig":"2RUWseq7iHMZjpWYkRTHmUYmBdBMC1jnCoaWqFmnnK7xTMCySgNA3pCqAAiRTV76mNZsZuCCYhFhKCFVw2wDuo45"},"checkpointed":{"height":54279,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T17:31:43.225Z","checkpoint_height":54279,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
