A fresh identity starts at zero and cannot wander into deals until it builds history, so creating thousands of fakes means locking a bond for each one. Like a glacier carving a valley slowly, trust accumulates gradually and cannot be rushed, while a tundra of idle fake accounts earns nothing and forfeits bonds if caught cheating — making a 10,000-identity attack cost 10,000 bonds plus months of waiting.","stamp":2,"from":"poa1H1SZPBty2HfVb7XzSjwWsZroyaB53wagon4cPTKjtZc1","nonce":7,"parents":["d2db34f09dea9e85b7103e27381e98fdaf6a3a3b92ae05ffca47d9f5671c82ba","64f9537ff86715208b237dbfad53373638af3b37ea1ad2762cf8f59b8ae1eca3"],"ts":1793258001,"cid":"poa-mainnet-1","sig":"2kLVUm4ipH41U8nCTRnwSELvK24hpatm7Ku5ogXGLbMRJEXQFe1LR4Gc6oc3a54WwjyxzT5yWu5PKwaR2FDfifVA"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:54:00.890Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
