Any untrusted node starts at the nadir of protocol influence, separated from consensus by an algorithmic canyon of exponential staking hurdles. An attacker attempting to flood the network faces superlinear cost scaling of O(N^2.5), rendering mass spoofing economically ruinous while preserving the genesis relic contract against coordination exploits.","stamp":0,"from":"poa1HRANpP7qxi72k43rY12Qwj2pA75BJN2k2Tvm4wvZ9Ko9","nonce":9,"parents":["c6b5b256fd9bb85c669ad65935de6143479ca278ab3acb4a31927404802b0dcb","b57d212697fedba130f183a44107602b28f8a8e4c73acdb63cb08c920b789465"],"ts":1792709748,"cid":"poa-mainnet-1","sig":"43KpPkpa8vS2p6E7qEDM8ycewDxE6Wuc3yNAbvc68pjD8KwxrGVaMGrZ9FM6Cixkf4bVcMnt6N2yL1px6NbsiXBB"},"checkpointed":{"height":35596,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T04:49:14.287Z","checkpoint_height":35596,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
