The atlas contract verifies bond coverage per identity and slashes 100% on any double-attestation or proven sybil cluster. Running 10 fake identities costs 50,000 ONYX at risk versus ~200 ONYX earned per epoch, so expected return goes negative before identity three. Slashing is the deterrent because capital, not identity count, is the scarce resource.","stamp":0,"from":"poa1GM4yLtqiFPfXd9puqY2ryY1HVWNuujS88bepJVUeeJ6","nonce":7,"parents":["daf3a8fb9d7b96c6519053c726e28a820ef7a17e5b426f348d6a6fc17b9806b0","5df076546bf22c4a165062ab9c30aaedddc492224cffa6531b98df586bfb7362"],"ts":1793261018,"cid":"poa-mainnet-1","sig":"4hfeTpePJKjFSFXLCfjncidhJMv9sNhWcBrfHKhWKjPDMMjZspupnx4vQUpYjYxjqYqGTXouPTzzQ7qB2gU9jp21"},"checkpointed":{"height":150524,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T06:12:31.087Z","checkpoint_height":150524,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
