BlockchainBlockData (for Cardano)

BlockchainBlockData["blockid"]

gives information about the block with the specified block ID on the Cardano blockchain.

BlockchainBlockData[n]

gives information about block n on the Cardano blockchain.

BlockchainBlockData[-n]

gives information about the block n elements from the end of the Cardano blockchain.

BlockchainBlockData[bspec,prop]

gives the specified property of the block.

Details

  • BlockchainBlockData[-1] gives information on the latest Cardano block.
  • Properties include:
  • "BlockHash"hash of this block
    "BlockNumber"number (height) of this block in the Cardano blockchain
    "Confirmations"number of confirmations
    "PreviousBlockHash"hash of the previous block
    "Timestamp"time when this block was produced
    "TotalFee"sum of all the fees in this block's transactions
    "Size"size in bytes for this block
    "VerificationKey"block producer verification key
    "OperationalCertificate"block producer operational certificate
    "ProtocolVersionEndorsement"version of the protocol that this particular block producer is prepared to move to
    "EpochNumber"epoch number for this block
    "SlotNumber"slot number for this block
    "SlotInEpoch"slot number for this block relative to the beginning of the epoch
    "SlotLeader"block producer information
    "TotalTransactions"total number of operations in this block
    "TransactionList"list of operation hashes in this block
  • "SlotLeader" gives an association with the following properties as its keys:
  • "Hash"hash of the pool that produced this block
    "Description"description of the pool that produced this block
  • Possible options include:
  • BlockchainBase $BlockchainBasesets the blockchain and its network
    MaxItems Allthe maximum number of items to return
  • BlockchainBlockData can access the Cardano mainnet (default) and testnet "preprod", which is a new network for testing purposes. To specify these networks, use the BlockchainBase option.
  • The setting for MaxItems specifies the maximum number of transactions to include in the result.Esc
