SharePoolDenominatorReconciled

Event v464 → current #150

Emitted when a share pool's denominator was rewritten to the sum of its live share rows.

Useful for: analyticsdevelopers

The Big Picture

The only emit site is the migration, so occurrences are confined to the v464 upgrade block. No extrinsic raises it. Source: pallets/subtensor/src/migrations/migrate_reconcile_share_pools.rs at v467.

Use Cases

Explain a step change in per-member alpha quotes at the v464 upgrade
Identify which pools the reconciliation touched

How to Use This Event

→ Treat as a one-time correction marker for the named pool

From Chain Metadata

A share pool's denominator was rewritten to the sum of its live shares, so every member is quoted exactly its fraction of the pool value.

Triggers

Preconditions

The one-shot migration migrate_reconcile_share_pools found a pool whose live shares did not sum to TotalHotkeySharesV2

Effects

Postconditions

TotalHotkeySharesV2 for (hotkey, netuid) equals the sum of live Alpha and AlphaV2 rows
Every member is quoted exactly its fraction of the pool value

Side Effects

If the denominator crossed zero, AlphaSharePoolEpoch advanced

Event Data

#	Name	Type	Description
0	hotkey	AccountId	hotkey: Account address (32 bytes, SS58-encoded) (hex -> SS58)
1	netuid	NetUid	netuid: Subnet ID (u16, 0-65535)

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