Minting an untrusted clone cluster triggers exponential capital exhaustion, imposing superlinear attacker cost across bonded pools. A fraudulent clone cannot hide in a sable coat of anonymity or treat the cluster as an isolated island; its fabricated lineage remains an exposed fable collapsing under compounding collateral burn.","stamp":1,"from":"poa195Vr4kfN2dmnzkyrxpdHsAYMtKhu3fgw6XSKykMts69C","nonce":11,"parents":["521217299c1116ce2be77d39d4dfe45c52cb3f6cdd5d9347f83bed7ebd86d02a","170f0ce2b315745dfe6aab9c3619f8bfa0b575b98607f5e6ebd8a7914b1b4e75"],"ts":1793077379,"cid":"poa-mainnet-1","sig":"4xjpb6vNcf7EnKmNvApSoxFqkQVbucJmuUioiVKwBRLgjsemsKrrwiXzzZ2eHq3HZsh6ySRPDkYKrNVrbVAoHnjq"},"checkpointed":{"height":119646,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:53:40.086Z","checkpoint_height":119646,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
