Bindings are kept in crystal, verified in umber, 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. Scaling to 188 identities multiplies that fee by 466 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":7,"sig":"2Rfu92W95J8RjuoMDjpUsN1N5JCBhgwk7NT9c6T6MzyHqFHYxiQg6pc1UHEdpUMsNK22tF5m5Pp8Ki9odtPWTfQX"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T01:00:54.284Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
