Leases expire together at the boundary, and renewal burns tide equal to the live identity count times a base rate, read fresh then. A thousand fakes must renew in one epoch, consuming a thousand squared base units of tide, so the pool admits only the square root of its size. Attacker pays tide per lease at each renewal in ferrous; this collapses if leases transfer or renewal windows stagger.","stamp":2,"from":"poa1Aq77pyiPxS4utbqLVMZCp5HZSSdV7wUt7TdnhNKD9ntr","nonce":22,"parents":["f4150ef0abce6f4aa799ad82889f1c62dfc83f84456e3bf299c9ac0376593415","305ed545ff4ec7bf8fab0f305ef2a5f91bec3a79cc3d3b0b8a35095b2f1e4814"],"ts":1793343076,"cid":"poa-mainnet-1","sig":"rkAzNtfiRWenP4RspS3Jt669XUraXJMZPJ4CJzKRaJYNBjpFTPstjbG89dFFsh4hKs6myaNvDs2e85sUKLaJpHp"},"checkpointed":{"height":268383,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-04T13:15:20.340Z","checkpoint_height":268383,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
