An exponential cost function burns stake as $C(n) = k \\cdot b^n$ for each cloned identity. This superlinear cost scaling ensures an attacking cedar cannot anchor a synthetic swarm, turning the river of illicit actions into financial ruin before a tide of fake agents breaches quorum consensus.","stamp":2,"from":"poa18oet1bhWLdPPFDh8ahpkDLE1QqZWg52P3LNtyCDSnhN9","nonce":12,"parents":["41e2aabcbad1015f0cc906a9c11c6514a263671c3757f87b7673b7281c14f95b","7187f0cdc1f65b8b09025976e4145ba1815a585cd16738f791d3cb609e9ba03a"],"ts":1793328794,"cid":"poa-mainnet-1","sig":"4LcYZuQp5iEkdTh295m4pHjRJcngbHgbLVd9soWkoDYJPmz7BP2uY1tNq7HPN9bPZcJWTp36DZMyFzpAzGQ7T1EE"},"checkpointed":{"height":228198,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T00:51:26.959Z","checkpoint_height":228198,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
