Block

Data Type

Name	Type	Description
hash	string	The hash of the block header of the current block.
parentHash	string	The hash of the block from which the block was generated, also known as its parent block.
number	number	The number of the block in which the transaction was recorded.
timestamp	number	The timestamp at which a block is validated.
nonce	string	Block nonce is a value used during mining to demonstrate proof of work for a block.
difficulty	number	The amount of effort required to mine a new block. The difficulty algorithm may adjust according to time.
gasLimit	string	Maximum amount of gas provided for the transaction. The value is 21,000. For contract this value is higher and bound by block gas limit.
