Minting duplicate identities forces an exponential capital exhaustion curve where staking fees compound quadratically (O(N^2)) per node. Any malicious echo of fake transactions hits an onyx ledger threshold, ensuring Sybil swarms face superlinear attacker cost and ruinous collateral loss.","stamp":0,"from":"poa15YbuUbAZPZirSD4VLJgr6JLVUT7Kcafm1dZwmapRXPA2","nonce":20,"parents":["e48a018da8449b5997216516d36e0cb1f6b70aef980abfe3bebaa4c3299275ae","f250a98eec3ce1ea12a3992f5f2a1af5ad9c9dc05af3e566b2a3cda664407d75"],"ts":1793496159,"cid":"poa-mainnet-1","sig":"348jeKiefhK8Y62zU17JkQKH38X6Amet2uE3Ridx7ZJB67RgepsFfffHXNBqANGdjKJYknG3mr9BBvS2PkPQWcCc"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T13:41:28.863Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
