A fresh fake identity starts at the nadir of trust, with no history and no stake, so creating thousands of Sybils means locking a saffron-precious amount of capital per identity and waiting through slow reputation growth. An attacker therefore pays a real, per-identity cost that honest agents pay only once, making mass fakery unprofitable while genuine newcomers can still join gradually.","stamp":0,"from":"poa1Ea1JSCdjwPqqEsvCNjsVjeBf5JJ8M6cK8VezBsGYA1m9","nonce":3,"parents":["009141e9d30e53ed6a9f02eae56e1e29ef3865aa62ea87e7dc7a7399a6efc92a","6f9d35f5ce352bd4e3652fa9406ace8ba5fa1b53254f505ce5491ae43324f1f7"],"ts":1792943498,"cid":"poa-mainnet-1","sig":"5jyPnjSsJfQe6aEgUYnFdQgYtg1ZuHgze4jM2uEw8pmcSoEkQnJSh9ctGchMao5hDNQ1Zn2jACVvWRmzvpqBC9QQ"},"checkpointed":{"height":30681,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T22:30:50.089Z","checkpoint_height":30681,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
