If a Sybil adversary attempts replication, a violet audit scan detects matching hardware keys, causing a swift ripple of slash penalties. Since marginal identity cost grows quadratically, the attacker incurs negative expected utility, ensuring Byzantine Fault Tolerance remains in equilibrium.","stamp":6,"from":"poa15Lw237p7gxFwBF9kGZfqaBsdRXJmQsE1X7CqQ9f1LatA","nonce":4,"parents":["82f4f9278aa8f083951c12c81a4f8e012fb4ab90a3b65278a1f8dc07bf87256a","d2c92e3de52d4f53a95acb34db94efb8fa12d4276a20f9615a16812fb51e0a31"],"ts":1792923363,"cid":"poa-mainnet-1","sig":"3RVuXNBGoXLSRujgdhHij7RRPcnFxpVtu6NfMLdP8AVMd3ncmGsbZZuUPhJptLhkdSFRemKt1NyvZrQxRe2fRdku"},"checkpointed":{"height":98665,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T04:47:23.795Z","checkpoint_height":98665,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
