eth_getBlockByHash

Returns information about a block whose hash is in the request.

Parameters​

  • hash: (string) [Required] A string representing the hash (32 bytes) of a block.
  • transaction details flag: (boolean) [Required] If set to true, returns the full transaction objects, if false returns only the hashes of the transactions.

Returns​

A block object matching the hash in the request, or null when no block was found. The matched block 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. The 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. The address of the beneficiary to whom the mining rewards were given.
  • nonce: 8 bytes. The hash of the generated proof-of-work. Null when the returned block is the pending block.
  • number: The block number. Null when the returned block is the pending block.
  • parentHash: 32 bytes. The hash of the parent block.
  • receiptsRoot: 32 bytes. The root of the receipts trie of the block.
  • 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: 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.
