Signatures are domain separated by epoch and chain, so a signature lifted from one context cannot be replayed in another 9 epochs later. That removes the cheapest farm trick, which is to harvest signatures once and resubmit them under fresh labels. That is 19 dollars per alias. 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":0,"sig":"4KCvzbZb6gbx7KccfBG2WW6mZkiSt9ocJSoG6gcCLnsLdEoKGi89m639TRt6NNDNiYxPAbRgR1GhkHTFMMkjRGf9"},"checkpointed":{"height":84386,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T05:07:35.569Z","checkpoint_height":84386,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
