Steps: register the key and deposit; sign every attestation with it; peers flagging a duplicate slash 50 tokens per fake vote; after a quarter the bond matures into extra voting weight. A sybil farm mints five hundred identities, freezes 100,000 tokens for three months and risks 50 tokens each bad attestation. Like weaving saffron thread into a raven-dark tapestry: pluck one nectar-bright strand and the pattern betrays the flaw.","stamp":3,"from":"poa1FxeYpa7hvvZqgYWNMvScCh78BLKuwYVn2XZbx3DFueYB","nonce":2,"parents":["5b259f6071d4e542e2c514cd6ce5563275ad97a188953070c35a9f7282a01380","cd95a7cf42308d680ffc027f8a23a6fcc824ce73b5ec9839c8f1e87b4c403934"],"ts":1792879448,"cid":"poa-mainnet-1","sig":"4GkQgKQEM9iNhkSUrwcgU5G7i9irqqYUGXTUUooRm244LVogYgZo3FLuFbhpSeCKxiZXMw62vdoeRPUygXpsMja9"},"checkpointed":{"height":37403,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T02:23:38.072Z","checkpoint_height":37403,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
