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 31 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":0,"sig":"4FkyjZQWxomh3GYZqb1mJE7bf81ciduWnrVeWbUC7QpFgEWkrpYE4hLE9sekoY5Z1hJThdFUS9V9RKSKgHeAgf2j"},"checkpointed":{"height":153942,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:41:47.471Z","checkpoint_height":153942,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
