Parameters​

  • block parameter: [Required] A hexadecimal block number, or one of the string tags latest, earliest, pending, safe, or finalized. See the default block parameter.
  • show transaction details flag: [Required] If set to true, returns the full transaction objects. If false returns only the hashes of the transactions.

Returns​

A block object, or null when no block was found. The returned block object contains the following keys and their values:

  • difficulty: A hexadecimal of the difficulty for this block.
  • extraData: The "extra data" field of this block.
  • gasLimit: Maximum gas allowed in this block.
  • gasUsed: Total used gas by all transactions in this block.
  • hash: 32 bytes. Hash of the block. Null when the returned block is the pending block.
  • logsBloom: 256 bytes. The bloom filter for the logs of the block. Null when the returned block is the pending block.
  • miner: 20 bytes. Address of the beneficiary to whom the mining rewards were given.
  • nonce: 8 bytes. Hash of the generated proof-of-work. Null when the returned block is the pending block.
  • number: Block number. Null when the returned block is the pending block.
  • parentHash: 32 bytes. Hash of the parent block.
  • receiptsRoot: 32 bytes. The root of the receipts trie of the block. Also see Tries in Ethereum.
  • sha3Uncles: 32 bytes. The SHA3 of the uncles data in the block.
  • size: A hexadecimal of the size of this block in bytes.
  • stateRoot: 32 bytes. The root of the final state trie of the block.
  • timestamp: The unix timestamp for when the block was collated.
  • totalDifficulty: A hexadecimal of the total difficulty of the chain until this block.
  • transactions: [Array] An array of transaction objects, or 32 bytes transaction hashes depending on the last given parameter.
  • transactionsRoot: 32 bytes. The root of the transaction trie of the block.
  • uncles: [Array] An array of uncle hashes.
