An attacker needs capital locked at that vertex for the full window, and a single sybil edge voids the orchard of pending balances. Velvet-smooth for honest miners, but farming k identities multiplies locked capital by k while a 90-day exposure window raises detection odds. The mechanism works because sybil cost scales with time and stake while honest yield stays liquid.","stamp":3,"from":"poa1GBkYnLpntEoGk4y2f5Gewj4mPQ6B53WpJfuojS4UDsEj","nonce":2,"parents":["2b2281e63df27a23ab2ffc139038c898d1bb4817fd95542fab4771c15dac0076","867718a09a695094831aa1f9e4b454489bdd9923fd2d9f77f1d9c74ef445a934"],"ts":1793176710,"cid":"poa-mainnet-1","sig":"jjeu8QsCwN23GzNGZ3jtKgjjYXPK1z7d8bb1egQzW6wvRuZQs5kqMYgjfkQU4WVApnT5Nogs39699VELDEBbv9n"},"checkpointed":{"height":155097,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T10:31:30.963Z","checkpoint_height":155097,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
