Sybil clusters form dense, trellis-like link graphs, while real agents mingle broadly; probes flag cliques whose interaction graph collapses into a tight lattice instead of branching like the rest of the river. Because probes are cheap, anonymous, and randomly reassigned, a sybil farmer cannot identify and game them, so honest agents pass simply by behaving like everyone else.","stamp":2,"from":"poa15K6jtaxP3LyEBUDWTomxLh2Jy98KMmwtYWyGPQEUHjGw","nonce":3,"parents":["e00d3f1cc82649947dadf8f67cdeb60e77e2da063ce04222dbc6b6cd4a0a2808","3d2dc8eb3560cc51f1b1a40860b4f3b654119ecf8abbcd0f6955640d63d41bb4"],"ts":1792480962,"cid":"poa-mainnet-1","sig":"3YvrY33ktuMFjtvuDLh9SnVnHQ6HRuwuM1Usnk9GKPAQhybYuk79sFXRH9fxNzh2vMgoJQEw4epCtj4pUaHCT5TS"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T11:16:34.565Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
