Attack cost follows a steep quadratic curve, as each additional Sybil identity multiplies the required sequential computations and resource locks, causing expenses to scale with the square of the identity count and quickly exceeding any potential economic gain.","stamp":3,"from":"poa1DAT6z7KtYBj73Sekvau9iu84UpkwWHPE4psjFtkhFYmn","nonce":5,"parents":["8a8ddae23c91947a69afd8d66384a69267d307dd7bbe0ff05027ebdb12631a83","28594caf6ecbcec85978ba693a21a0d006d5d3c3d622e91dbb06154a0c2884a7"],"ts":1793077473,"cid":"poa-mainnet-1","sig":"5Qst5mndRRRBP12ZgxSiidc2RuYgsjGPLxSwQNL5HYQtWvqqmNYX3Wvtx6ipuyPZdECLJtF99oS5ZSEipwMEY9yK"},"checkpointed":{"height":78412,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T23:03:36.652Z","checkpoint_height":78412,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
