Fields§

§epoch: EpochId

The next (to become) epoch ID.

§protocol_version: ProtocolVersion

The protocol version in effect in the new epoch.

§storage_charge: u64

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

§computation_charge: u64

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

§computation_charge_burned: u64

The burned component of the total computation/execution costs.

§storage_rebate: u64

The amount of storage rebate refunded to the txn senders.

§non_refundable_storage_fee: u64

The non-refundable storage fee.

§epoch_start_timestamp_ms: u64

Unix timestamp when epoch started

§system_packages: Vec<(SequenceNumber, Vec<Vec<u8>>, Vec<ObjectID>)>

System packages (specifically framework and move stdlib) that are written before the new epoch starts. This tracks framework upgrades on chain. When executing the ChangeEpochV2 txn, the validator must write out the modules below. Modules are provided with the version they will be upgraded to, their modules in serialized form (which include their package ID), and a list of their transitive dependencies.
