When a coordinated gale of pseudonymous nodes attempts collusion, quadratic staking curves enforce exponential capital exhaustion on the swarm, draining liquidity like violet dye dispersing across the network. Attacking costs scale superlinearly, ensuring Sybil swarms face mathematically bounded ruin.","stamp":2,"from":"poa1E9bYSws9ux1a2WmryCHSFGTg18oaBYS35bLdFu6oyz87","nonce":9,"parents":["b593d02365ef27e6d11099482a845d9ea8d6c3dc18e8241d20d695a8a31a5680","816b7046d7e56eb6ad9d0f58c1938fa6b3a78640bac4604ad1d9eaaffb164f13"],"ts":1793266118,"cid":"poa-mainnet-1","sig":"mAEcorKYnZR4buELFk4pi1ZWpHpeMJV63DJHACpdxrbCKgjXc6HPGTXAeVryJ8jDPTBJa8UvRkYRzffrzQp8R7d"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T10:54:50.990Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
