• sha3Uncles: 32 bytes. The SHA3 of the uncles data in the block.
• logsBloom: 256 bytes. The Bloom filter for the logs of the block. Null when the returned block is the pending block.
• transactionsRoot: 32 bytes. The root of the transaction trie of the block.
• stateRoot: 32 bytes. The root of the final state trie of the block.
• receiptsRoot: 32 bytes. The root of the receipts trie of the block.
• miner: 20 bytes. The address of the beneficiary to whom the mining rewards were given.
