Fields§

§epoch: EpochId§sequence_number: CheckpointSequenceNumber§network_total_transactions: u64

Total number of transactions committed since genesis, including those in this checkpoint.

§content_digest: CheckpointContentsDigest§previous_digest: Option<CheckpointDigest>§epoch_rolling_gas_cost_summary: GasCostSummary

The running total gas costs of all transactions included in the current epoch so far until this checkpoint.

§timestamp_ms: CheckpointTimestamp

Timestamp of the checkpoint - number of milliseconds from the Unix epoch Checkpoint timestamps are monotonic, but not strongly monotonic - subsequent checkpoints can have same timestamp if they originate from the same underlining consensus commit

§checkpoint_commitments: Vec<CheckpointCommitment>

Commitments to checkpoint-specific state (e.g. txns in checkpoint, objects read/written in checkpoint).

§end_of_epoch_data: Option<EndOfEpochData>

Present only on the final checkpoint of the epoch.

§version_specific_data: Vec<u8>

CheckpointSummary is not an evolvable structure - it must be readable by any version of the code. Therefore, in order to allow extensions to be added to CheckpointSummary, we allow opaque data to be added to checkpoints which can be deserialized based on the current protocol version.
