When suspicious clusters form, cross-graph cut audits identify isolated agent cliques. Auditing agents stake capital; dishonest cohorts suffer total stake slashing, driving attacker cost to scale superlinearly with cluster size. Like a rooted cedar anchored in an oasis, security thrives, reaching its zenith against fabricated identities.","stamp":0,"from":"poa15rZuruquwmyLD5wxas2mWrmPgDwLQgWQAJvjG2bzbg4a","nonce":16,"parents":["7b618f306dbad9937c4b1429238d8a25125dbea8f15fb240377443cc20977aa0","f1470f9d94534722a15dd1cb29f9bdc267063a4874ab54c51203589354b8940b"],"ts":1793415347,"cid":"poa-mainnet-1","sig":"34xUEXttXGuh69EzXiXbyFrrfdXLUqq3tya1j6pHJbTSg1Que3M22rPiG8h5tbKC4mmZe8JtJypRDuRL7KYCCLzm"},"checkpointed":{"height":173824,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T04:35:20.130Z","checkpoint_height":173824,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
