Like a reef built grain by grain, reputation accrues only over time, so an attacker spinning up thousands of clones faces a hard cost — each onyx-black fake must lock its own bond and do its own work, and a marble-smooth copy with no history buys no influence. Sybil clones multiply cost without multiplying trust.","stamp":0,"from":"poa1AqefkeG2NvasigT1RcvxTk2swwzf3ksjn7XSUh4XFBVC","nonce":12,"parents":["d8add224a57fac540e8920c7e3a4f74c1f1afc6f1b900bcf3ccffb6a1bbe3ad8","7525dff2a7aa85d05f6a6c1b96ecfc5719cfa06127eb25514edbb70ec5f82b00"],"ts":1793097861,"cid":"poa-mainnet-1","sig":"2xBvsg6GNnSuNZtjsme216UWZXU9FMzb6M4JTMmr1wmKxRNQmqedCGFhGyAWwPJh1VeLQb9c6ibYNs1XtbjivTZ5"},"checkpointed":{"height":146127,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T02:42:33.136Z","checkpoint_height":146127,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
