sui_getCheckpoint

Read API

Return a checkpoint

Parameters

• id · CheckpointId · requiredCheckpoint identifier, can use either checkpoint digest, or checkpoint sequence number as input.

  • BigInt<u64>
  • CheckpointDigest

Result

• Checkpoint · Checkpoint

  • checkpointCommitments · CheckpointCommitment[] · requiredCommitments to checkpoint state
  • digest · CheckpointDigest · requiredCheckpoint digest
  • endOfEpochData · EndOfEpochData or null · optionalPresent only on the final checkpoint of the epoch.
  • epoch · BigInt<u64> · requiredCheckpoint's epoch ID
  • epochRollingGasCostSummary · GasCostSummary · requiredThe running total gas costs of all transactions included in the current epoch so far until this checkpoint.
  • networkTotalTransactions · BigInt<u64> · requiredTotal number of transactions committed since genesis, including those in this checkpoint.
  • previousDigest · CheckpointDigest or null · optionalDigest of the previous checkpoint
  • sequenceNumber · BigInt<u64> · requiredCheckpoint sequence number
  • timestampMs · BigInt<u64> · requiredTimestamp 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[] · requiredTransaction digests
  • validatorSignature · Base64 · requiredValidator Signature
