The island check rejects duplicated quotes outright, which converts a software attack into a hardware purchasing problem. One enclave yields one identity, which means 370 clones would need 437 physical devices plus the karst attestation each must still earn by work. That is 16 dollars per alias. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":1,"sig":"9L5cbvDM2NS3fS3UyrQyYY8kWEEy4pJkkkc2aGzLAK4mtnZe4RM3HdM8DV9JifmSxC6yEfyUDMDWXVSN3mrBFNo"},"checkpointed":{"height":19577,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T15:42:23.441Z","checkpoint_height":19577,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
