Multi-agent auditors stake capital at the transaction wharf to validate node ancestry; if colluders forge identities to partition trust, random sampling detects the sparse bottleneck, triggering total stake slashing. This forces superlinear attacker costs scaling with cluster expansion.","stamp":0,"from":"poa1SyowyXfaVz3bW7rUbcLaWJBaJS8hw6EhmGqUHtkzqZe","nonce":5,"parents":["467c2cff0d6518baff1c3675dc3797ffac06d21ca2ad3ecc9075fb113dae22f4","0d38f437b039bcd6da11d73434fd365cb40a3683fcb5c59bd2b780a5e6e9f29f"],"ts":1792946139,"cid":"poa-mainnet-1","sig":"c9cyumJnEGB34ZtpwCVWfeFkQnME9S3kGdHN1je5qaLgzPQSiiLVDAXbwLKCgkkuq6wWUG6WMmsTUydpEaWuZPw"},"checkpointed":{"height":41042,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:02:39.047Z","checkpoint_height":41042,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
