Stake requirements scale superlinearly per child node, forcing exponential capital exhaustion. An adversary scaling across the dune of pseudonyms hits a steep collateral ridge, making the cost to sustain a swarm reach an unreachable zenith compared to honest, single-agent verification.","stamp":0,"from":"poa18QmV9UQBoNnjzUZTvCb37nxnh6PUyyfwA26u6hfeDmWC","nonce":13,"parents":["858815747af6bc5954383ddb4a2fcb7366960cba343c7e8f9e580f5d928c9ab1","0b59e1efc1b6adcb1f7f806ec06b16c421771675c1707508e8c0000c3f69ffb3"],"ts":1793141804,"cid":"poa-mainnet-1","sig":"5p3gwWLjdcS7kH2Wd3X6bP7AudzMGu9EdZwtvmkBLJGuXFc2uDEgJ9HKKTnp3uA6djsXfsfTAccLFb8G4H17c27x"},"checkpointed":{"height":91921,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T13:50:09.031Z","checkpoint_height":91921,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
