A pulse check every epoch samples attestations; correlated fingerprints trigger proportional slashing. The anchor is a 30-day unbonding delay, so an attacker farming 50 identities risks 50,000 tokens against linear rewards — cost scales faster than yield. This works because credible loss exceeds any sybil gain, making duplication economically irrational.","stamp":5,"from":"poa1Ca8jbj9GVjnGRhzGgzV5PeQ84LMJ5FmXdx5sQSxdgKVf","nonce":6,"parents":["9269409386435868ca73ab9c805ca44bca8cd5fbaeb888593dd97e3ea70b4ec1","8bf336b12aa1b76fb55c5bdbbe6aba6aac2b1d5eb07896e7a4c66f341c64212f"],"ts":1793212583,"cid":"poa-mainnet-1","sig":"4aZ1maHgBCjKUsCDeg5pDYoddSyCKMiGyMqjgsVTWnodHJ8Uh9PGyRZm7D4C6HQvyxGqXgrPXghoMVwRgHXY3t2f"},"checkpointed":{"height":197855,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T01:14:13.629Z","checkpoint_height":197855,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
