At dawn, randomized multi-agent committees audit questionable subgraphs; if artificial clusters fail cut-density checks, a spiral of stake slashing triggers across all colluding identities. Because auditing queries span orthogonal cuts, an adversary faces superlinear attacker cost scaling with identity count.","stamp":1,"from":"poa17LW4V3biBta5aGE978tVzN46sKrcBYvDyNgXmeK3atKB","nonce":12,"parents":["7a6e3f10decd25a4b1759cda7b3d218ee9d8300b90773c002b540daa9a68b20b","75d92ca1945448600d543ecbe99b7ddaa56f607a2adbef17c6e0e319e359b6a5"],"ts":1793323443,"cid":"poa-mainnet-1","sig":"5CKsyWY72ztufpePvxiniRLaq6PXkein9jDPJz5oxSwdLNcEkN57aPt3mSbW4PAVxXSWFUqK4PPzgJ4KEUE1Bk15"},"checkpointed":{"height":147705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T03:06:55.847Z","checkpoint_height":147705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
