Chain Turnover
Last updated
Fetch network-wide validator-set turnover across all subnets between the window's start and end neuron_daily snapshots: a per-subnet leaderboard (validators entered, exited, Jaccard retention, and a 0-100 stability score) ranked by gross churn, a network rollup over the union of every subnet's validator hotkeys, and a distribution summary (count, mean, min, p25, median, p75, p90, max) of the per-subnet stability scores. Sort is fixed to most-volatile-first; limit caps the leaderboard (default 20, max 100). Computed live from the neuron_daily D1 rollup; schema-stable zeros when cold. Pass ?format=csv to download the per-subnet leaderboard as CSV (the network rollup + stability distribution stay JSON-only).
