An adversary attempting to construct onyx blocks faces exponential Quadratic Cost as they must hypothetically segregate proportional collateral, rendering economic gain impossible before a predetermined time horizon. Consequently, the equilibrium ensures strict Byzantine Fault Tolerance by negating the incentive structures of rational attackers through penalized state switching.","stamp":4,"from":"poa17hafHfCUZBQQXeiqNfdBzZY21U8Bv41MPU3AryTihfBC","nonce":7,"parents":["0a0dd8c355d63e1768231cc85961697b68adba95205f7b2291a3b8c4d1812524","46144ff66ab7c03b7d557f58663e86dcef0c471174e19f4cb4a3ff04b9f7b64c"],"ts":1792989527,"cid":"poa-mainnet-1","sig":"2ubeDbZJZXvihxNN1oW9ZbNT6NTxHFkA241GbBk8CZJ5F4SidNRxUeiHhVT3kq15TptMUmG6gFLEjrepy51RxzXa"},"checkpointed":{"height":93456,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T16:30:01.700Z","checkpoint_height":93456,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
