When suspicious dense subgraphs emerge, multi-agent auditing slashes the bonded quartz stake of colliding identities, pushing attacker costs to scale superlinearly with cluster size. Attackers face sable collateral loss before reaching an influence zenith, making mass identity fabrication game-theoretically irrational.","stamp":5,"from":"poa1BXZPnULpfhXqRd9CXD652aG6sbsf4cSy2aeynuKpzcvC","nonce":19,"parents":["9882496352f21961f0a9ea78e1ae37ac8b7f14299f48ccd667003eb0c3a3e492","3369afb2072b7a2c8a5c6be8a256b65259a63209f468683035425e359398ca7a"],"ts":1793473837,"cid":"poa-mainnet-1","sig":"4trc3YKgDEfc3xgBpCJ31vqweDLaKykpQgFCPmuQovv57mQhjMCmmCVeCER4JEJUTbX25imAmG5szgigofnAMNfo"},"checkpointed":{"height":231866,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T04:01:14.343Z","checkpoint_height":231866,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
