Parameters

OBJECT - The filter options:

Object Name	Required	Type	Detail
`fromBlock`	❌	String	A hex code of an integer that represents the block number, or "latest" that represents the last mined block.
`toBlock`	❌	String	A hex code of an integer that represents the integer block number, or "latest" that represents the last mined block.
`address`	❌	String/Array	Contract address or a list of addresses from which logs should originate.
`topics`	❌	Array	Array of 32 Bytes `DATA` topics. Topics are order-dependent. Each topic can also be an array of `DATA` with "or" options.
`blockHash`	❌	String	Restricts the logs returned to the single block with the `blockHash`. If blockHash is present in the filter criteria, then neither `fromBlock` nor `toBlock` are allowed.

Result

It is an array of log objects, or an empty array if nothing has changed since last poll.

For filters created with eth_newBlockFilter the return are block hashes (DATA, 32 Bytes), e.g. ["0x123456789..."].
For filters created with eth_newFilter logs are objects with the following fields.
