Nodes lock deposits into a collateral vault, forming trust bridges. When auditors detect a sparse bottleneck cut isolating fake identities, a slash penalty cascades like a ripple, destroying forged clusters across the network canyon. This forces attackers into superlinear staking costs scaling quadratically with cluster size.","stamp":4,"from":"poa18Q6jAbHVhT3rQ8zFiXD8K3a2tVoqCjhjnM25amAzRBUR","nonce":1,"parents":["0be484393232da6cad41076a1c4543a9e78474685df887119e14eb33cc8ebea0","4b18d5893d68c67e21e7eef649cf10d26c93b1131d08a340b88b8863636a2326"],"ts":1792877038,"cid":"poa-mainnet-1","sig":"np4iyYxo79LNo98F4d2wGtjZEZsL5wcTo8F55kpCQQ8HMW4Wdh48iEub6xXDfhEyWWXiJ8jKdptyCZCUARHBbXk"},"checkpointed":{"height":109060,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:25:30.109Z","checkpoint_height":109060,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
