Returns the number of hashes per second that the node is mining with.
Please note that it always return 0 because there is no PoW mechanism in Klaytn.

## eth_getWork <a id="eth_getwork"></a>
Returns the hash of the current block, the seedHash, and the boundary condition to be met ("target").
Please note that it always return `errNoMiningWork` because there is no PoW mechanism in Klaytn.
**Parameters**
None
**Return Value**
| Type | Description |
|-----------------------|-------------------------------------------------------------------------------------------------------------------------------|
| Array of 32-byte DATA | List of current block header pow-hash, the seed hash used for the DAG, the boundary condition ("target"), 2^256 / difficulty. |
**Example**
```shell
// Request
curl -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"eth_getWork","params":[],"id":1}' http://localhost:8551
// Result
{
"jsonrpc": "2.0",
"id":1,
"error": {
"code": -32000,
"message": "no mining work available yet"
}
}
eth_submitWork
Used for submitting a proof-of-work solution.
Please note that it always return false because there is no PoW mechanism in Klaytn.
Parameters
Type
Description
8-byte DATA
The nonce found (64 bits)
32-byte DATA
The header’s pow-hash (256 bits)
32-byte DATA
The mix digest (256 bits)
Return Value
Type
Description
Boolean
Returns true if the provided solution is valid, otherwise false.
This method creates an accessList based on a given Transaction. The accessList contains all storage slots and addresses read and written by the transaction, except for the sender account and the precompiles. This method uses the same transaction call object and blockNumberOrTag object as eth_call. An accessList can be used to unstuck contracts that became inaccessible due to gas cost increases. Adding an accessList to your transaction does not necessary result in lower gas usage compared to a transaction without an access list.

Return Value
Type
Description
Object
Returns list of addresses and storage keys used by the transaction, plus the gas consumed when the access list is added.
The transaction call object. Refer to for the object's properties.
Integer or hexadecimal block number, or the string "earliest", "latest" or "pending" as in . The block number is mandatory and defines the context (state) against which the specified transaction should be executed.
