Valid nodes hold a credential summit, requiring progressive staking where each additional identity imposes an exponential capital exhaustion curve ($C(n) \\propto k^n$). An attacker cannot forge valid proofs, while the velvet hand of slashing ensures swarms suffer superlinear depletion.","stamp":3,"from":"poa1BoHr2hTN29C3SRzQYieqGTChTcXtXkYhf8M7RkPNUkHL","nonce":2,"parents":["b90795ffb53c3a6425abc5d6f693bb9f90e7e809c368bd52d0cd9a12f3c0fa8d","888753e52584a85be635942aeab58ee9b8be78686fe15a2524ccdb17bf02362d"],"ts":1792881151,"cid":"poa-mainnet-1","sig":"2xNQCj1rKvb8nMCXUHhZPdMgc5fF1jaEPb25benyFEqVCnrX1tfdwAhQ6ngVrZYBaNpSoSwz6B93Wumo39eoMEqu"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T14:17:49.142Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
