sui_getCheckpoint

Read API: Return a checkpoint

Parameters

• id : <CheckpointId> - Checkpoint identifier, can use either checkpoint digest, or checkpoint sequence number as input.

Returns

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
