Signatures are domain separated by epoch and chain, so a signature lifted from one context cannot be replayed in another 4 epochs later. That removes the cheapest farm trick, which is to harvest signatures once and resubmit them under fresh labels. Slashing removes 94 percent at once. 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":"5VxXnAjUeBBWiAJVFY823yS8fK5w4xoKBQGBeJz2T1MtuJQA5NgZ16sp19KTZG6PMFw6HRjd6njmAmmv3FMsVUfV"},"checkpointed":{"height":122489,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T00:33:45.143Z","checkpoint_height":122489,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
