Returns information about a block by block hash.

🚧

The live code example will not work, please refer to the examples below instead

For context, this has to do with OpenAPI compatibility with JSON-RPC requests. We're working on a solution here but in the meantime, check out the composer tool to make requests from the browser.

Parameters

  • Hash - Hash of the block
  • Boolean - If true it returns the full transaction objects, if false only the hashes of the transactions.
params: [
    '0xe76d777791f48b5995d20789183514f4aa8bbf09e357383e9a44fae025c6c50a', 
    true
]

  • parenthash - Hash of the parent block.

  • nonce - Hash of the generated proof-of-work. null if pending.

  • sha3uncles - SHA3 of the uncles data in the block.

  • logsbloom - The bloom filter for the logs of the block. null if pending.

  • transactionsroot - The root of the transaction trie of the block.
