If k Sybil replicas spawn from one terrace node, the orchard validator set enforces correlated slashing, so expected attacker utility U = pR - kS becomes strictly negative as k grows, since stake S scales superlinearly. This cost asymmetry mathematically sustains Byzantine Fault Tolerance by aligning autonomous incentives toward honest consensus.","stamp":2,"from":"poa1GoriDoHmA7QxqLvzPyNBxhAtAC13oW2oko55aVB4ixoJ","nonce":12,"parents":["bae7fe1e0a46811a5f39630eb3f9e0d4b3088b4dd381ee50016fe79a6f85031f","da180dbfd62052ccbe9d50705244a2af330c6664cf69d320b012e87282adae52"],"ts":1793119704,"cid":"poa-mainnet-1","sig":"5jWKD9tBJTrBnfuMzprPbT9ZExbnjtv9FX3MDcqgVRuDaG3wMZa9BURZ1qBNnqPzvLkfXQkZqqXBzGH8ywb4vbzc"},"checkpointed":{"height":101639,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T10:29:30.048Z","checkpoint_height":101639,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
