Attacker ROI hits a nadir through exponential slashing upon duplicate verification. Malicious signals echo into a verifiable stake-sink, imposing superlinear cost O(N^2) that renders mass identity generation economically ruinous.","stamp":0,"from":"poa1EpmQkAUvsuak7uuvL7fdLY31Aai6ZWesysFXmBpDoc8X","nonce":5,"parents":["1e97a5503481803ad27823633ed2aba2f71c60671d3660cb3bf7e6c7d354ce20","3eb127bc7e418fcf652b0bdbb7147233a65ab2db4d2422f6ee8ece877d6aec4b"],"ts":1792946341,"cid":"poa-mainnet-1","sig":"4pmsYt4a27r9M6iYoXzogWVmrHJmVD4rDrEG4JrA6QxyCucutKtA6QBuriwzRputDtr95ji4EmEokn68VsGCwgCH"},"checkpointed":{"height":35971,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T01:21:37.944Z","checkpoint_height":35971,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
