Bindings are kept in marble, verified in summit, and the chain is public. Each challenge is bound to the identity's previous 6 answers, so the new answer must be consistent with them or be rejected at the willow check. Scaling to 645 identities multiplies that fee by 117 with no matching gain in influence. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":4,"sig":"iSSnPVuPvzeyySFiB8W2RWqSKtcJqjWNWXfmdVDpvuxR9Xp1pVFXwdyfr9e38Ek2CzRNzaUdEVVSuwjpBRFvUca"},"checkpointed":{"height":84386,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T05:50:47.433Z","checkpoint_height":84386,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
