validator-threshold v1.0.0

What is SubQuery?

SubQuery powers the next generation of Polkadot dApps by allowing developers to extract, transform and query blockchain data in real time using GraphQL. In addition to this, SubQuery provides production quality hosting infrastructure to run these projects in.

SubQuery Example - Validator Threshold

This subquery indexes the least staking amount required for a validator to be elected.

This is an example of using @polkadot/api in the mapping function. Proofs: 1. historical metadatas are correctly handled, registry, consts are swapped. (see maxNominatorRewardedPerValidator) 2. Queries are restricted to the current processed block. (see validators and exposures) 3. api.queryMulti is supported. (see activeEra, currentEra)
