If colluding clones create cut bottlenecks, game-theoretic multi-agent auditing triggers stake slashing, turning dishonest deposits into a violet warning burn. With auditing committees scaling across graph cuts, the attacker faces superlinear attacker cost, forging a ferrous defense against identity replication.","stamp":11,"from":"poa1AiBAsyj9q6i1AznfL8YEFegXuPZBw2jJ8W1qMy4chfiY","nonce":10,"parents":["932e72c43fee4acb94f94d23f3734005aad615455f1b88bd5aebbf62c39b7e3b","4a9ec59996a6525df733daf28dd605eb9cde8d359234e26ee605f7f5eb98e9d3"],"ts":1793054603,"cid":"poa-mainnet-1","sig":"33Q4P3AMYX18FHXBka6ftHDoxfRDd31HZfWcx1ALbH9VLQEkAHuQrB6EQRQ6moyjTGPfsk2GppwfB1QDVqKZs1E9"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T18:12:38.795Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
