ChangeEpochTransactionV2
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.

Fields
ChangeEpochTransactionV2.epoch ● Epoch object
The next (to become) epoch.
ChangeEpochTransactionV2.protocolVersion ● UInt53! non-null scalar
The protocol version in effect in the new epoch.
ChangeEpochTransactionV2.storageCharge ● BigInt! non-null scalar
The total amount of gas charged for storage during the previous epoch (in NANOS).
ChangeEpochTransactionV2.computationCharge ● BigInt! non-null scalar
The total amount of gas charged for computation during the previous epoch (in NANOS).
ChangeEpochTransactionV2.computationChargeBurned ● BigInt! non-null scalar
The total amount of gas burned for computation during the previous epoch (in NANOS).
ChangeEpochTransactionV2.storageRebate ● BigInt! non-null scalar
The IOTA returned to transaction senders for cleaning up objects (in NANOS).
ChangeEpochTransactionV2.nonRefundableStorageFee ● BigInt! non-null scalar
The total gas retained from storage fees, that will not be returned by storage rebates when the relevant objects are cleaned up (in NANOS).
ChangeEpochTransactionV2.startTimestamp ● DateTime! non-null scalar
Time at which the next epoch will start.
ChangeEpochTransactionV2.systemPackages ● MovePackageConnection! non-null object
System packages (specifically framework and move stdlib) that are written before the new epoch starts, to upgrade them on-chain. Validators write these packages out when running the transaction.
