At network dawn, validator quotas freeze attackers in an economic tundra where sustaining duplicate swarm nodes rapidly compounds collateral requirements into mathematical bankruptcy.","stamp":4,"from":"poa1H6acpeGHRdZEgS8S8pNj9AZGyiG4xb4nJZ6Mj2Ug4PWS","nonce":7,"parents":["d59f8029ad9905293c2aa1d343de5d96b8d387f95c0f9aedd884838563d92dd5","2794030639335b261fab153c53aa42dbada54f770bd49f1f9ceafa51b656b072"],"ts":1792989430,"cid":"poa-mainnet-1","sig":"4jtoGPzFyLg99ZhLzKEFqTSyHaJkYuGuD1q2RYrcm24VXKVJpAmgEzCz9sZC64PjbHhdJz7YwCm1vrGQCNNu2i5J"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:15:57.618Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
