Distinct auditing rings—such as saffron, raven, and glacier clusters—independently sample transactions; any collusion triggers bonded stake slashing. Creating fake identities scales attacker cost with superlinear attacker cost penalties as graph min-cut expansion imposes compounding deposit requirements.","stamp":1,"from":"poa14sSpbJS3WJT4Cg6UCrPXUj69vCkcgNCDRUjYxStJfYqS","nonce":10,"parents":["b6d5d32dd292b961ec807c5d87bf1a09c41290a2e503ae3820a686ae20d1e835","9e6595dfe2d7c24129a19dbedf6c3c89769377bbc69fe849235ec19e0de64741"],"ts":1793281866,"cid":"poa-mainnet-1","sig":"Xg9zdWFh1Jr94XoSqh4gvnNqCygmL3gVmtC9vwRUQHNXWqaJXT5TQqabwbHfRErqirEio8BtLfPCDshRh7i71kG"},"checkpointed":{"height":112430,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T18:37:43.751Z","checkpoint_height":112430,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
