Chain Deregistrations
Last updated
Fetch network-wide neuron-deregistration activity over a 7d or 30d window across the subnets with observed deregistration activity (subnets with no NeuronDeregistered events are absent): a per-subnet leaderboard (NeuronDeregistered event count, distinct deregistered hotkeys, and average deregistrations per hotkey) ranked by total deregistrations, a network rollup with the true distinct hotkey count (a hotkey deregistered on several subnets counts once) and total deregistrations, and a distribution summary (count, mean, min, p25, median, p75, p90, max) of the per-subnet re-deregistration intensity. limit caps the leaderboard (default 20, max 100). Raw deregistration/eviction activity — the exit-side companion to GET /api/v1/chain/registrations and the account_events companion to the neuron_daily validator-set churn in GET /api/v1/chain/turnover. DERIVED from UID reuse in the NeuronRegistered stream by a scheduled projection (NeuronDeregistered has never been emitted by the runtime); the payload's derivation block states how many window registrations had no observable previous holder, and degraded marks an answer nothing derived. Pass ?format=csv to download the per-subnet leaderboard as CSV (the network rollup + intensity distribution stay JSON-only).
Query Parameters
Trailing lookback window the response is computed over, ending at the most recent data point rather than at today. Accepts 7d, 30d. A longer window is not a superset of a shorter one -- rankings and rates are recomputed over the whole window, not summed.
"7d"Value in
- "7d"
- "30d"
Maximum number of rows to return in one page (at most 100). A larger value, or a non-positive one, is rejected with 400 invalid_query -- so a short page means the result set is exhausted, not that the server quietly capped you (#9916). Omitted, the server applies 20.
1 <= value <= 10020Response format override. Use csv to download the route rows as text/csv; json keeps the default response envelope.
"json"Value in
- "json"
- "csv"
