Because the lantern expiry is policed at the copper gate, the bridge audit records each accepted timestamp and a late replay is rejected. A nonce is valid for 149 seconds from issue and then expires, so an operator cannot stockpile signed submissions and release them later. That is 25 dollars per alias. 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":1,"sig":"G4ixjeDU7QA5u7cuRAeR4Q5vxzoMfRqyY4PYzdRNRP5QbsWZAEDyWsXUgRSZJNDB2uKKeLza9VypFmJhY6cgaFK"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T21:00:06.748Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
