An epoch slot was deferred to the next block due to the per-block epoch cap.

Part of: Epoch Processing

Migration Notes

v424 v432 Breaking

netuid changed from u16 to NetUid

Update decoders: SCALE encoding is positional, so any signature change (added, removed, or type-changed fields, or storage shape changes) shifts byte offsets and existing decoders will misparse this item. Re-derive types from the new metadata.

Code Examples

import { createClient, Binary } from "polkadot-api";
import { getWsProvider } from "polkadot-api/ws";
import { sub } from "@polkadot-api/descriptors"; // generated by: npx papi add sub -w wss://entrypoint-finney.opentensor.ai:443

const client = createClient(getWsProvider("wss://entrypoint-finney.opentensor.ai:443"));
const api = client.getTypedApi(sub);

// Subscribe to EpochDeferred events
client.finalizedBlock$.subscribe(async (block) => {
  const events = await api.event.SubtensorModule.EpochDeferred.get(block.hash);
  for (const evt of events) {
    console.log("EpochDeferred:", evt.payload);
  }
