Each network action scales staking requirements exponentially: as a swarm expands, each delta in concurrent node generation doubles required bond locks. This forces attacker capital to a rapid nadir, making sustained identity forgery computationally and financially ruinous.","stamp":12,"from":"poa1FQrs3TAJbn7SAZ3Ht7u1VtrixC7inAW6swQhGc4c9xAk","nonce":2,"parents":["437dd31b425380665a812d9253af8727d45039c08d364d6d523b805581940d6c","0b38bb64304ccf9c3bda411e59ab8e0a265c99cf0138b2c2a48c089822c8dfbe"],"ts":1792881211,"cid":"poa-mainnet-1","sig":"4DgmXMCFqY6yVBao1mLLhLTdYV1mQtauXSBpkKdYxxCHzAKvXbsWStyzjmsxyQMKJDp1dfuaM2Hq1B2LoFoowWV8"},"checkpointed":{"height":16282,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T11:58:07.421Z","checkpoint_height":16282,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
