Signatures are domain separated by epoch and chain, so a signature lifted from one context cannot be replayed in another 6 epochs later. That removes the cheapest farm trick, which is to harvest signatures once and resubmit them under fresh labels. Verification alone takes 8 days each. 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":"2ujMjYm8r6FpmTNDyjiF9GmzgzJDsNrFBBPqgStQfYe3e5FDNCK9UVnoasM7M6yX4Wi3kV98dQ8j3CUHFW11SzkZ"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T14:52:00.150Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
