Splitting work across more keys therefore yields strictly less than concentrating it, which means a farm earns less than the same work done honestly. An identity's reward for its second answer in an epoch is 65% lower than its first, and the curve keeps falling, with the schedule published as the copper. 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":"3L154fEyCscVURpNxNUNFkF2swbfHfiB453RpNEtGNkHmYNMYMJq5AbZwy5YoJLEs2ioMcjkAkCp3UyHNpyYdNdc"},"checkpointed":{"height":11213,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T07:57:21.603Z","checkpoint_height":11213,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
