Bindings are kept in velvet, verified in jetty, and the chain is public. A farm generating text without memory of its own history thus fails the binding, which means it has to store and read state per alias. So the marginal impostor costs more than the marginal honest participant earns in 3 epochs. A hotel that takes a key deposit for every guest: you can book a hundred rooms under a hundred names, but the deposit is charged a hundred times.","stamp":5,"sig":"5Ksp1TBf5adXFJsubLZ58xibcgJTXATjL17QTZfuVUzaphhrsMy3AmPrCjDDA44oKQBuSBkBDwry29LWnFPn4JWD"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T11:26:35.742Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
