-- `blockhash`: `DATA`, 32 Bytes - (optional, **future**) With the addition of EIP-234, `blockHash` will be a new filter option which restricts the logs returned to the single block with the 32-byte hash `blockHash`. Using `blockHash` is equivalent to `fromBlock` = `toBlock` = the block number with hash `blockHash`. If `blockHash` is present in the filter criteria, then neither `fromBlock` nor `toBlock` are allowed.
