Return a checkpoint

Parameters

Key	Required	Type	Detail
id	✅	String	Checkpoint identifier, can use either checkpoint digest, or checkpoint sequence number as input.

"params": [
  "1000"
]

Result

Checkpoint : <Checkpoint>

checkpointCommitments : <[CheckpointCommitment]> - Commitments to checkpoint state
digest : <[CheckpointDigest]> - Checkpoint digest
endOfEpochData : <[EndOfEpochData]> - Present only on the final checkpoint of the epoch.
epoch : <[BigInt_for_uint64]> - Checkpoint's epoch ID
epochRollingGasCostSummary : <[GasCostSummary]> - The running total gas costs of all transactions included in the current epoch so far until this checkpoint.
networkTotalTransactions : <[BigInt_for_uint64]> - Total number of transactions committed since genesis, including those in this checkpoint.
previousDigest : <[CheckpointDigest]> - Digest of the previous checkpoint
sequenceNumber : <[BigInt_for_uint64]> - Checkpoint sequence number
timestampMs : <[BigInt_for_uint64]> - 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
transactions : <[TransactionDigest]> - Transaction digests
validatorSignature : <[Base64]> - Validator Signature
