A farm running 149 keys cannot self-supply these, since each counter-bonding peer must be independent on the violet graph and each one exposes its own stake to the same slash.

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":8,"sig":"obTK9fcpkHQoTeDsZFhcaGHcuJbx9st2DYPhtmra4gpLYLre3hjURZSPQdcgcg7MK23wLbyDRiny8qBDr8aUfyJ"},"checkpointed":{"height":30681,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T22:33:35.081Z","checkpoint_height":30681,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
