Parameter Description

Parameter	Type	Description
Block hash	String	The hash of a block.
Uncle index position	String	The uncle's index position in hexadecimal.

Return Value

Object: A block object with the following fields, or null when no block was found:
- number: the block number of the requested block, encoded as hexadecimal. It is null if the block is pending.
- hash: the hash of the block. It is null if the block is pending.
- parentHash: the hash of the parent block.
- nonce: the hash used to demonstrate proof-of-work. It is null if the block is pending.
- sha3Uncles: SHA3 of the uncles data in the block.
- logsBloom: the bloom filter for the logs of the block. It is null if the block is pending.
- transactionsRoot: the root of the transaction trie of the block.
- stateRoot: the root of the final state trie of the block.
- receiptsRoot: the root of the receipts trie of the block.
- miner: the address of the miner receiving the reward.
- difficulty: the difficulty for this block.
- totalDifficulty: the total difficulty of the chain until this block.
- extraData: the "extra data" field of this block.
- size: the size of this block in bytes.
- gasLimit: the maximum gas allowed in this block.
- gasUsed: the total used gas by all transactions in this block.
- timestamp: the Unix timestamp for when the block was collated.
- transactions: an array of transaction objects, or 32-bytes transaction hashes, depending on the last given parameter.
- uncles: an array of uncle hashes.
