Commitments to checkpoint state

object 1object
ECMHLiveObjectSetDigestobjectrequired

The Sha256 digest of an EllipticCurveMultisetHash committing to the live object set.

digestinteger (uint8)[]required
digeststringrequired

Checkpoint digest

endOfEpochDataobject
epochCommitmentsoneOf[]required

Commitments to epoch specific state (e.g. live object set)

object 1object
ECMHLiveObjectSetDigestobjectrequired

The Sha256 digest of an EllipticCurveMultisetHash committing to the live object set.

digestinteger (uint8)[]required
nextEpochCommitteeoneOf[][]required

next_epoch_committee is Some if and only if the current checkpoint is the last checkpoint of an epoch. Therefore next_epoch_committee can be used to pick the last checkpoint of an epoch, which is often useful to get epoch level summary stats like total gas cost of an epoch, or the total number of transactions from genesis to the end of an epoch. The committee is stored as a vector of validator pub key and stake pairs. The vector should be sorted based on the Committee data structure.

nextEpochProtocolVersionstringrequired

The protocol version that is in effect during the epoch that starts immediately after this checkpoint.

epochstringrequired

Checkpoint's epoch ID

epochRollingGasCostSummaryobjectrequired

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

computationCoststringrequired

Cost of computation/execution

nonRefundableStorageFeestringrequired

The fee for the rebate. The portion of the storage rebate kept by the system.

storageCoststringrequired

Storage cost, it's the sum of all storage cost for all objects created or mutated.

storageRebatestringrequired

The amount of storage cost refunded to the user for all objects deleted or mutated in the transaction.

networkTotalTransactionsstringrequired

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

previousDigeststring

Representation of a Checkpoint's digest

sequenceNumberstringrequired

Checkpoint sequence number

timestampMsstringrequired

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

transactionsstring[]required

Transaction digests

validatorSignaturestringrequired

Validator Signature
