Key	Type	Value
number	Quantity, Integer	Block number. `null` when block is pending.
hash	Data, 32 bytes	Hash of the block. `null` when block is pending.
parentHash	Data, 32 bytes	Hash of the parent block.
nonce	Data, 8 bytes	Hash of the generated proof of work. `null` when block is pending.
sha3Uncles	Data, 32 bytes	SHA3 of the uncle’s data in the block.
logsBloom	Data, 256 bytes	Bloom filter for the block logs. `null` when block is pending.
transactionsRoot	Data, 32 bytes	Root of the transaction trie for the block.
stateRoot	Data, 32 bytes	Root of the final state trie for the block.
receiptsRoot	Data, 32 bytes	Root of the receipts trie for the block.
miner	Data, 20 bytes	Address to pay mining rewards to.
difficulty	Quantity, Integer	Difficulty for this block.
totalDifficulty	Quantity, Integer	Total difficulty of the chain until this block.
size	Quantity, Integer	Size of block in bytes.
gasLimit	Quantity	Maximum gas allowed in this block.
gasUsed	Quantity	Total gas used by all transactions in this block.
timestamp	Quantity	Unix timestamp for block assembly.
transactions	Array	Array of transaction objects, or 32 byte transaction hashes depending on the specified boolean parameter.
uncles	Array	Array of uncle hashes.
baseFeePerGas	Quantity	The block’s base fee per gas. This field is empty for blocks created before EIP-1559.
Key	Type	Value
oldestBlock	Quantity, Integer	Lowest number block of the returned range.
baseFeePerGas	Array	Array of block base fees per gas, including an extra block value. The extra value is the next block after the newest block in the returned range. Returns zeroes for blocks created before EIP-1559.
gasUsedRatio	Array	Array of block gas used ratios. These are calculated as the ratio of `gasUsed` and `gasLimit`.
Key	Type	Optional	Value
fromBlock	Quantity \| Tag	Optional	Integer block number or `latest`, `pending`, `earliest`. See Block Parameter. Default is `latest`.
toBlock	Quantity \| Tag	Optional	Integer block number or `latest`, `pending`, `earliest`. See Block Parameter. Default is `latest`.
address	Data \| Array	Optional	Contract address or array of addresses from which logs originate.
topics	Array of Data, 32 bytes each	Optional	Array of topics by which to filter logs.
Key	Type	Value
output	Boolean	Transaction result. 1 for success and 0 for failure.
stateDiff	Object	State changes in the requested block.
trace	Array	Ordered list of calls to other contracts.
vmTrace	Object	Ordered list of EVM actions.
transactionHash	Data, 32 bytes	Hash of the replayed transaction.
