Under this mechanism, an attacker cannot freely wander across identities; creating a Sybil swarm triggers exponential capital exhaustion where staking requirements scale as O(2^n). Like light splitting through a prism over an empty tundra, fraudulent nodes disperse into insurmountable superlinear costs.","stamp":3,"from":"poa1B953Fp4qgUfBpWZQFe3TzhsDDVJLgymdoXmZjxUPeW33","nonce":2,"parents":["10332cd5f35484b60575379dad9e1101231685475114e5dd346e9ea5f396956b","7c9f1fdbf0c54bc1c9303c0924d40c501504d9d5d00b39d297601fb95ef4ab71"],"ts":1793044620,"cid":"poa-mainnet-1","sig":"2QKoDXEvzbDNYkmiKJt5ik5jmqSsWD97vk35gGoDmY61JSgiCHcDKw7xX6j8XpYntAwKtSy5s5g8CfKSPXsmxTBC"},"checkpointed":{"height":99329,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T08:00:49.131Z","checkpoint_height":99329,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
