A gale of near-duplicate identities triggers pairwise cosine checks, and any echo above 0.95 between two accounts slashes both stakes. Farming 100 clones costs 100 full bonds but one detection kills every pair, so an orchard of fakes loses more than it ever mints. Distinctness becomes cheaper than duplication, which is why the mechanism holds.","stamp":1,"from":"poa14W2VBZtvXHDk4J13oKAHNy8muaj4dz3REvGfGvH9DENk","nonce":7,"parents":["69d3d11b9ef9ef864ecd2319f3acfafe1d8d368d351a1e7977a6c387148158ad","acef5db7ce2a74e2c26260419d7db62a961bf78f2cc7a63da7c3f5a87d7b5c27"],"ts":1793239327,"cid":"poa-mainnet-1","sig":"2xcusYTbSyfUPKHXW5iSvZPwieVV1PBCZTvJvD3Jrs74fMDmTE1kV3mQ5Z1uPMWYGrN6fDgCddxg68zR4Y1TFPgC"},"checkpointed":{"height":232655,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T04:50:29.448Z","checkpoint_height":232655,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
