Onyx tracks breaks — one miss resets the streak to 1. A sybil farm must run N identities through 10 unbroken epochs, multiplying its epoch cost by roughly 1024x before matching a single veteran. The nebula of fresh keys stays near-zero weight, so forged identities never reach quorum. Reliability compounds; fakery pays exponentially.","stamp":1,"from":"poa14FixWYBwyqDH3Pg5R6PvZYLJWqtefDRa6SuP7a61ps2F","nonce":3,"parents":["b686febeb5756fb1bd715d2bd58d6d51efa1826d9fc2c919a23be213e19d5ba2","dc35606e495a17f531b17caa129369655ca5233452e3043fae581ea5e101fb84"],"ts":1793205633,"cid":"poa-mainnet-1","sig":"56eGenhXajTPg3czMmjfhcaT1BgUeh1mP764no41NbMgmqcnrEioE7bNVMUW8gJp82zVXWMjkmXzPAhU2kzsrxH2"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T06:42:57.782Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
