Returns data from the staking ledgers The staking ledger of the current epoch is the snarked ledger of the last block of current epoch minus two.

​
Stake by Delegate

Filters the staking ledger for delegates. Summing the balance determines the stake of the delegate in the current epoch. Timing may be used to determine if the account is eligible for the supercharged coinbase rewards. If there is timing available, the following fields are included:
  • timed_in_epoch is a boolean that is true if the account has a time-locked balance at the start of the epoch.
  • untimed_slot is the global slot at which the account is no longer timed. Useful if the account is untimed during the epoch.
  • timed_epoch_end is a boolean that is true if the account has a time-locked balance at the end of the epoch. Returns null if timed_in_epoch is false .
If the account has no timing information in the ledger timing will return null .

Determine the Last Block of Epoch

The next staking ledger is only available after k blocks from the last block of the prior epoch. Adding k to the following result will determine when the next epoch ledger is available. 
{
  blocks(
    query: {protocolState: {consensusState: {epoch: 1}}}
    sortBy: DATETIME_DESC
    limit: 1
  ) {
    protocolState {
      consensusState {
        blockHeight
      }
    }
  }
}

curl -d '{"query":"{\\n  blocks(\\n    query: {protocolState: {consensusState: {epoch: \\"1\\"}}}\\n    sortBy: DATETIME_DESC\\n    limit: 1\\n  ) {\\n    protocolState {\\n      consensusState {\\n        blockHeight\\n      }\\n    }\\n  }\\n}"}' https:__graphql.minaexplorer.com

{

          }
        }
      }
    ]

​
Filter Delegates to only those with Timed Account

Only show those delegates that have a timed account at the start of the current epoch. 
{
  stakes(
    query: {
      delegate: "B62..."
      timing: { timed_in_epoch: true }
    }
  ) {
    public_key
    balance
    timing {
      cliff_amount
      cliff_time
      initial_minimum_balance
      vesting_increment

      untimed_slot
      timed_in_epoch
      timed_epoch_end
    }

Balances and total count of delegators

You can retrieve the total amount delegated and total number of delegators to a staking pool.

  stake(query: {public_key: "B62qpge4uMq4Vv5Rvc8Gw9qSquUYd6xoW1pz7HQkMSHm6h1o7pvLPAN"}) {
