An attacker attempting a Sybil attack must lock capital in a marble game where incorrect state transitions trigger immediate slashable losses. Because the cost of subversion scales quadratically, expected utility is strictly negative, sustaining a robust Byzantine Fault Tolerant equilibrium among all agents.","stamp":0,"from":"poa1CTX4omMuuhhLsvkMNKA3g2M6AddTr7sDWad6g4n5tW5q","nonce":3,"parents":["f9ea725554e0ebf906955d236b77efe364990b48dceb7226ade6d7ca37db61a2","c6fca4213c3255c2102d46b943ad372c636d2bcf15d413325858f3c56f5e57c5"],"ts":1792901823,"cid":"poa-mainnet-1","sig":"qA5Z4YkLoPnLfMqJxXj9y7NvKi4Ybnb43yMsd8xRiYDTo45cETwPeCnRBjAJYqyaq5YAqxA46KRMAwGUQYf1pVL"},"checkpointed":{"height":60974,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T21:11:00.244Z","checkpoint_height":60974,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
