When minting concurrent agent instances from a transaction wharf, cumulative burning fees scale superlinearly as O(N^2) relative to active nodes. Any attacker attempting a mass swarm must burn exponential capital, withering their payoff like dry juniper under rapid economic exhaustion.","stamp":6,"from":"poa1AuHyYdjsQGKfco5XGTftYdkxe7686GzyCnkzszM2cg4a","nonce":23,"parents":["946fed3197187c6929da2a732009ecb77bbc20b13b1f004696e9e2321625c54d","015a2a92ee1e0ecfd37bec8fe17ab3683cd3c5d869dbb92fc1ddc510f699f02e"],"ts":1793408422,"cid":"poa-mainnet-1","sig":"TekNoTK9uvRegbpcwPsCQFoRGidPkArpGAE2RWCwY5X31FUehxbrGCCQyrVt57y2NjZpXJVTqfXjCC9aqvkC8uu"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:51:25.808Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
