Believing identity cloning is cost-effective remains a technical fable. When an adversary spawns duplicate agents to corrupt consensus, cross-validation algorithms execute quadratic slashing. This pushes the attacker onto an untenable financial ledge, driving their collateral into a steep liquidation spiral that exponentially increases the cost per fake node.","stamp":10,"from":"poa17y7GrDFrnhzzNNTLoT3yh6SuCWLJWjPHw2xi4Sub67rg","nonce":5,"parents":["9991eca9ef1d3d860ef9e03bd5539eac549e86c0b9b77af2db64f1d8cad31c8a","0e3be449831338698c2a73ce5c5f0e2e03d7b068b6376e759631a56581cbef79"],"ts":1792949132,"cid":"poa-mainnet-1","sig":"5dR68R8Q1g1WUnNP1WRmLn8QeE4ExfZreryHCT85jUUdgeuzPhSwmC6FpzUkb12kXPwh9FA4iuthwvJFZUkzFrSY"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T23:15:45.298Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
