The `miner` API allows you to remote control the node's mining operation and set various
mining specific settings.

{:toc}
### miner_getHashrate
Get your hashrate in H/s (Hash operations per second).
| Client | Method invocation |
|:--------|-------------------------------------------------------------|
| Console | `miner.getHashrate()` |
| RPC | `{"method": "miner_getHashrate", "params": []}` |
### miner_setExtra
Sets the extra data a miner can include when miner blocks. This is capped at
32 bytes.
| Client | Method invocation |
|:--------|----------------------------------------------------|
| Go | `miner.setExtra(extra string) (bool, error)` |
| Console | `miner.setExtra(string)` |
| RPC | `{"method": "miner_setExtra", "params": [string]}` |
### miner_setGasPrice
Sets the minimal accepted gas price when mining transactions. Any transactions that are
below this limit are excluded from the mining process.
| Client | Method invocation |
|:--------|-------------------------------------------------------|
| Go | `miner.setGasPrice(number *rpc.HexNumber) bool` |
| Console | `miner.setGasPrice(number)` |
| RPC | `{"method": "miner_setGasPrice", "params": [number]}` |
### miner_start
Start the CPU mining process with the given number of threads and generate a new DAG
if need be.
| Client | Method invocation |
|:--------|-----------------------------------------------------|
| Go | `miner.Start(threads *rpc.HexNumber) (bool, error)` |
| Console | `miner.start(number)` |
| RPC | `{"method": "miner_start", "params": [number]}` |
### miner_stop
Stop the CPU mining operation.
| Client | Method invocation |
|:--------|----------------------------------------------|
| Go | `miner.Stop() bool` |
| Console | `miner.stop()` |
| RPC | `{"method": "miner_stop", "params": []}` |
### miner_setEtherbase
Sets the etherbase, where mining rewards will go.
| Client | Method invocation |
|:--------|-------------------------------------------------------------|
| Go | `miner.SetEtherbase(common.Address) bool` |
| Console | `miner.setEtherbase(address)` |
| RPC | `{"method": "miner_setEtherbase", "params": [address]}` |

### miner_setGasLimit
Sets the gas limit the miner will target when mining. Note: on networks where EIP-1559 is activated, this should be set to twice what you want the gas target (i.e. the effective gas used on average per block) to be.
| Client | Method invocation |
|:--------|-------------------------------------------------------------|
| Go | `miner.SetGasLimit(number *rpc.HexNumber) bool` |
| Console | `miner.SetGasLimit(number)` |
| RPC | `{"method": "miner_setGasLimit", "params": [number]}` |
