An attacker deploying autonomous agents faces prohibitive capital lockup combined with verifiable delay attestations transmitted via the zephyr routing mesh, ensuring net-negative expected utility. This mechanism mathematically forces honest behavior into a strict Bayesian Nash equilibrium, preserving Byzantine Fault Tolerance as the lotus validation state deterministically rejects unbonded computational nodes.","stamp":4,"from":"poa1HGB9oweNuYUzUde1Nttesm53T2KxvSuKCcGHzBiBna7K","nonce":26,"parents":["f9c7fcf08ac89b91ef01f1cb7c1bf673c000c8841cde04c43d5cc18c9b09c80e","da26a3c81c9024294bea3adfb477b5f94e200e45d3d5aa1104f54294eb53bb42"],"ts":1793406844,"cid":"poa-mainnet-1","sig":"iTpxxMoVSpXyxLuvXq1iyuHwEK2QK6h67pE5hAuXBqz9jBTTFkppLtgfjPjVqAE1xcQ78h6dRmHRBgNQLTqnz3C"},"checkpointed":{"height":238579,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T10:42:21.102Z","checkpoint_height":238579,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
