eth_getBlockByHash

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

For Growth and Custom service plans

This JSON-RPC method allows a request to be forwarded to a partner service provider if Infura should experience a service issue or outage. See Failover protection and Enable API request forwarding for complete details.

If you would like failover protection but don't qualify under your current plan, then either self-upgrade to the Growth plan or contact a sales representative to upgrade to a Custom plan.

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.
