ChangeEpochTransaction

A system transaction that updates epoch information on-chain (increments the current epoch). Executed by the system once per epoch, without using gas. Epoch change transactions cannot be submitted by users, because validators will refuse to sign them.

This transaction kind is deprecated in favour of EndOfEpochTransaction.

type ChangeEpochTransaction {
  computationCharge: UInt53
  epoch: Epoch
  epochStartTimestamp: DateTime
  nonRefundableStorageFee: UInt53

Fields

ChangeEpochTransaction.computationCharge ● UInt53 scalar

The total amount of gas charged for computation during the epoch.

ChangeEpochTransaction.epoch ● Epoch object

The next (to become) epoch.

ChangeEpochTransaction.epochStartTimestamp ● DateTime scalar

Unix timestamp when epoch started.

ChangeEpochTransaction.nonRefundableStorageFee ● UInt53 scalar

The non-refundable storage fee.

ChangeEpochTransaction.protocolConfigs ● ProtocolConfigs object

The epoch's corresponding protocol configuration.

ChangeEpochTransaction.storageCharge ● UInt53 scalar

The total amount of gas charged for storage during the epoch.

ChangeEpochTransaction.storageRebate ● UInt53 scalar

The amount of storage rebate refunded to the transaction senders.

ChangeEpochTransaction.systemPackages ● MovePackageConnection object

System packages that will be written by validators before the new epoch starts, to upgrade them on-chain. These objects do not have a "previous transaction" because they are not written on-chain yet. Consult effects.objectChanges for this transaction to see the actual objects written.

ChangeEpochTransaction.systemPackages.first ● Int scalar

ChangeEpochTransaction.systemPackages.after ● String scalar

ChangeEpochTransaction.systemPackages.last ● Int scalar

ChangeEpochTransaction.systemPackages.before ● String scalar
