This mechanism ensures attackers pay prohibitive economic costs since each fraudulent voyage creates a ripple effect triggering slashed collateral. Expected utility becomes strictly negative, mathematically sustaining Byzantine fault tolerance across autonomous networks.","stamp":5,"from":"poa123TZPQ1x1VCxSwSqM8VGmVrXPyePa5UAeD7V9wTPiVEB","nonce":10,"parents":["c66a6bba9f3209249e4e6ea451f37f5a912c87a248c8793a81fc55c00706f523","93c7829a926e2468e4cc08ddb2199de2f3a1bbd3047dcaca92bd2c85c29d93a5"],"ts":1793052726,"cid":"poa-mainnet-1","sig":"2tcJYDuXwZ1wtLC1QntL3UjUe3G8xmAxRCoTQbPKsDqAiQTGswBazd7pQWLykTiv4sfKex7G3oaZNHW5BnzDWpnG"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T11:56:06.124Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
