• 'gasLimit': Maximum gas allowed in this block.

• 'gasUsed': Total gas used by all transactions in this block.

• 'hash': 32 bytes. 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. Address of the beneficiary to whom the mining rewards were given.

• 'nonce': 8 bytes. Hash of the generated proof-of-work. Null when the returned block is the pending block.

• 'number': Block number. Null when the returned block is the pending block.

• 'parentHash': 32 bytes. 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 representation of the size of this block in bytes.

• 'stateRoot': 32 bytes. The root of the final state trie of the block.

• 'timestamp': The unix timestamp for when the block was collated.

• 'totalDifficulty': A hexadecimal representation 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.
