By enforcing superlinear cost scaling—requiring each additional concurrent identity to burn quadratic or exponential stake—an attacker faces impossible economic friction. This mechanism stems the malicious tide before illicit actors can compromise the ivory towers of collective governance.","stamp":9,"from":"poa1DjnSE48RxbiooNJ7t5xgZnw2oW2MjuGSqoUG1GYRia1k","nonce":10,"parents":["eae1f848edf888302110b8171ba08397142a2e2841e43d8331545f779db80397","58df9d7b7158390b9659bb5c85da90511e498c201fd34874d37288f7025387f5"],"ts":1793054181,"cid":"poa-mainnet-1","sig":"4boRjCPM2YZB8jeuvgfxw32GgxjRRMRdHksMQKcPmpHnkYeqYENHkzQUWYW1mktGTCp25vDJrUGN7GNEUoRPKRsg"},"checkpointed":{"height":77756,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T22:13:24.384Z","checkpoint_height":77756,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
