Chain Concentration
Last updated
Fetch network-wide stake and emission concentration metrics (Gini, HHI, Nakamoto coefficient, top-percentile shares, entropy) aggregated across all subnets' neurons over three lenses (per-UID, per-entity with coldkeys collapsed across subnets into the network control distribution, and validator-only consensus power), computed live from the neurons D1 tier; schema-stable nulls when cold.
