getBlock

Returns the identity and transaction information about a confirmed block. This method uses 160 credits from your daily balance.

Parameters

• slot: (integer) [required] - The slot number of the block to query.
• config: (object) [optional] - Configuration object with the following options:
  • transactionDetails: (string) [optional] - The level of transaction details to include in the response. Possible values are:
    • none - No transaction details.
    • accounts - Transaction details only include signatures and an annotated list of accounts in each transaction.
    • signatures - Only the signatures of the transactions.
    • full - Full transaction details. This is the default option.
  • rewards: (boolean) [optional] - Whether to include rewards information in the response. The default is false.
  • encoding: (string) [optional] - The encoding format to use for the block data. Can be one of base58, base64, jsonParsed, or json
  • Returns the block data as a JSON object.
  • commitment: (string) [optional] The commitment level to use for the query. The default is finalized. Possible values are:
    • finalized - Queries the most recent block confirmed by a super majority of the cluster as having reached maximum lockout, meaning the cluster has recognized this block as finalized.
    • confirmed - Queries the most recent block that has been voted on by a super majority of the cluster.
    • processed - Queries its most recent block. The block may still be skipped by the cluster.
  • maxSupportedTransactionVersion: (integer) [optional] - The maximum supported transaction version to return. If the requested block contains a transaction with a higher version, an error will be returned. If this parameter is omitted, only legacy transactions will be returned, and a block containing any versioned transaction will prompt an error.

Returns

result - null when the block doesn't exist, or an object with the following fields:

• blockHeight - The number of blocks before this block.
• blockTime - The estimated production time, as Unix timestamp (seconds since the Unix epoch). It's null if not available.
• blockhash - The hash of the block encoded as a base58 string.
• parentSlot - The slot index of this block's parent.
• previousBlockhash - The block hash of this block's parent encoded as base58 string; if the parent block is not available due to ledger cleanup, the field returns 11111111111111111111111111111111.
• transactions - If full transaction details are requested, returns an array of JSON objects with the following fields:
  • meta - The transaction status metadata object, which contains additional information about the block and its transactions. The meta object can be null, or it may contain the following fields:
    • err - Error code if the transaction failed, or null if the transaction succeeds.
    • fee - The total fees paid by all transactions in the block encoded as u64 integer.
    • innerInstructions - An array of objects representing the inner instructions of all transactions in the block (omitted if inner instruction recording is disabled). Each object has the following fields:
      • logMessages - An array of strings containing any log messages generated by the block's transactions (omitted if inner instruction recording is disabled).
      • postBalances - An array of lamport balances for each account in the block after the transactions were processed.
      • postTokenBalances - An array of token balances for each token account in the block after the transactions were processed (omitted if inner instruction recording is disabled).
      • preBalances - An array of lamport balances for each account in the block before the transactions were processed.
      • preTokenBalances - An array of token balances for each token account in the block before the transactions were processed (omitted if inner instruction recording is disabled).
      • rewards - An object containing information about the rewards earned by the block's validators (only present if the rewards are requested). It has the following fields:
        • pubkey - The public key of the account that received the award encoded as a base58 string.
        • lamports - The number of reward lamports credited or debited by the account.
        • postBalance - The account balance in lamports after the reward was applied.
        • rewardType - The type of reward. It could be fee, rent, voting, or staking.
        • commission - The vote account commission when the reward was credited, only present for voting and staking rewards.
      • status - The status of the transaction. It returns Ok if the transaction was successful, and Err if the transaction failed.
    • transaction - The transaction object. It could be either JSON format or encoded binary data, depending on the encoding parameter.
      • message - An array of transactions objects included in the block:
        • accountKeys - An array of public keys associated with the accounts that were accessed during the execution of transactions in the block.
          • pubkey - The public key associated with the block producer that created the block.
          • signer - Indicates if the account is a required transaction signer. It can also be used to identify the signers involved in the block's transactions and to verify the authenticity of the signatures.
          • source - Identifies the accounts that provided the funds for the block's transactions.
          • writable - A boolean value that indicates whether the accounts associated with the given public keys were modified by the transactions or not.
        • instructions - An array of instructions that were executed in the block's transactions
          • parsed - An array of parsed instructions that were executed in the block's transactions
            • info - An array of information objects that provide additional details about the transactions in the block.
              • clockSysvar - Provides information about the current state of the blockchain.
              • slotHashesSysvar - Provides information about the hashes of recent slots.
              • vote - An array of vote accounts that were involved in the block's transactions.
                • hash - The hash of the block. It can be used to uniquely identify the block and to verify the authenticity of the block's contents.
                • slots - An array of slot numbers that correspond to the transactions in the block.
                • timestamp - The Unix timestamp of the block's creation.
              • voteAccount - A vote account to identify the validator that produced the block and to verify the validity of their vote.

            • type - The type of the block. It can be used to differentiate between regular blocks and special blocks such as snapshot or transaction confirmation blocks.
          • program - The data associated with the program that was executed in the block's transactions.
          • programId - The public key of the program that was executed in the block's transactions.
          • stackHeight - The current depth of the execution stack.
        • recentBlockhash - The recent block hash for the account's cluster.
      • signatures - The list of transaction signatures contained within a particular block.
