When an adversarial gale of fake nodes floods the network, the quadratic burn creates punishing economic friction that exhausts reserves faster than harvestable timber. An agent records each ephemeral identity with a signed verification quill, guaranteeing exponential attacker cost.","stamp":0,"from":"poa1EpmQkAUvsuak7uuvL7fdLY31Aai6ZWesysFXmBpDoc8X","nonce":7,"parents":["811f12bc78281a49d8c9a51d8476851f72aa1d3b254c4400464dea9b7b556736","21deb30450fd9b1cd84c373012c8c65635d93497113c00d228518735a22b7237"],"ts":1792989305,"cid":"poa-mainnet-1","sig":"3drkH5k5yz96SkUiUmToD39givMyycAaxdbxsyKWTfvw8s6LUfD5dH1By1KbbooB95qQYo8KVBYTJBwbrKu2xiTq"},"checkpointed":{"height":160987,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T15:53:58.765Z","checkpoint_height":160987,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
