Ferrous bonds lock 0.1 ETH per hop claimed; a sybil cluster 5 hops out must lock 5× per node. The haven for attackers collapses: forging depth k across n nodes costs n·k² stake, while honest paths stay at depth 1-2. Verdict: linear trust for honest users, quadratic cost for farms, so fake depth becomes unprofitable past ~8 nodes.","stamp":5,"from":"poa17vXQfUtPHbqxXdL8uwFc86MrbewZxpfAsgd4Y9kU1qah","nonce":4,"parents":["0cca6d643ef380fc68c5c3c03029c47b5cbffe591ba2be5841c62293d136d564","04ecf3f414fe8b5ab138010ab7e29d96b0c60535219dd648ee2856ff1191ee73"],"ts":1793168184,"cid":"poa-mainnet-1","sig":"3oTVTeB9sDMb9xugKNR7wDMgpB5Mzs8Vv4boeGhSGkwwCMGmXqQkxKjWE8A6jzspmDxQ1f3cySeotof6xT44GPCE"},"checkpointed":{"height":112430,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T18:18:58.875Z","checkpoint_height":112430,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
