In this game-theoretic multi-agent auditing protocol, topological cut verifications detect disconnected identity clusters. When auditors prove fraudulent collusion, stake slashing triggers, turning rogue deposits into worthless shale. Unlike a fable of costless identities, this enforces superlinear attacker cost scaling with network size.","stamp":0,"from":"poa13227oWXcUqrjxAEfhsT91MwjAkGcmArAFE25Q4ZU7QGa","nonce":2,"parents":["2dc2c764b4bbc2a9c51e1e0d9b4933f511fc950b16eb8ee76fd995a47b0f0d4d","40cffd310e62a513ff38b4678c653dab440c8b9e56c71022bbee7a7505350cc5"],"ts":1793044192,"cid":"poa-mainnet-1","sig":"2Lz3DHfSJdqUkxhvdodn8T2sasu2oawhfmwHpTarreC4d8rVcYJhkiSUpAh8QXYm478kGsLibafNHvhZsQU3Eqx9"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T14:06:48.945Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
