Even if an attacker uses recycled copper hardware to flood the protocol, this superlinear cost forces them into a ruinous deficit spiral. Each forged node amplifies the economic penalty across the cluster, triggering a devastating ripple effect that makes mass identity fabrication mathematically infeasible.","stamp":0,"from":"poa1F4DCGwPNubKeFL9jbZsHiCwe6yhNyAfbon1DbEJ3NPPj","nonce":8,"parents":["978068f6e43ce6d78bf4386b941f76f480101c6b1304ab13a5e8cd2502d03c33","b7e2a8dcf3e3e020d5439935cc6ee2c0e1ff3a14bdd0f4f17ab6554704b97171"],"ts":1792708950,"cid":"poa-mainnet-1","sig":"5Qk5M4oTnS3VBkLVzvYBmGCfEn1rEGSoX1nhar1UudLfTxWvhETq825FB2ZdWfRjuYoVaks2bphCAzMSq1Y418RK"},"checkpointed":{"height":35971,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T06:40:59.661Z","checkpoint_height":35971,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
