Returns information about a block by block hash.


  • DATA, 32 Bytes - Hash of a block.
  • Boolean - If true it returns the full transaction objects, if false it returns only the hashes of the transactions.
params: [


Object - A block object with the following fields, or null when no block was found:

number: QUANTITY - the block number. null when its pending block.

  • hash: DATA, 32 Bytes - hash of the block. null when its pending block.
