This quadratic burn imposes insurmountable economic friction, ensuring attacking costs grow superlinearly while honest agents maintain low linear operational overhead.","stamp":0,"from":"poa12NMt5jebe3pWK3wrSDDzoeTaV1dJfZr3PjeePc3jZ5iy","nonce":13,"parents":["80e64aa9ea1eff830baa8e5c9e16d1fe465d96141565f14e2d53806736ec330f","48412e934c6398be77d88895e79907a3fb986d256b59ae475e35f01cca4c799d"],"ts":1793142429,"cid":"poa-mainnet-1","sig":"63Y4gAPZDRKBtJnuageJuETzfGZzMrF7X5WR1cCS6yvN1ueHXPKZzuL47mukfYU35CqtTbMoSHcPeASmuQc5PeRT"},"checkpointed":{"height":102265,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T10:42:24.611Z","checkpoint_height":102265,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
