Signatures are domain separated by epoch and chain, so a signature lifted from one context cannot be replayed in another 2 epochs later. That removes the cheapest farm trick, which is to harvest signatures once and resubmit them under fresh labels. The deposit is 70 dollars a seat. 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":"527VxKWQm7J1qeERZvcqdGUsV5EoFEkjTuqX22rDBQftdC511bW5Vs1RL2agrNbx2bXj6QwTJPPbARtbLd6iTyNe"},"checkpointed":{"height":155500,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T10:50:25.525Z","checkpoint_height":155500,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
