# miner

The miner API is responsible to provide remote control the node's mining operation and set various mining specific settings.

### miner\_getHashrate <a href="#miner-hashrate" id="miner-hashrate"></a>

Get hashrate in H/s (Hash operations per second).

| CLIENT  | METHOD INVOCATION                               |
| ------- | ----------------------------------------------- |
| Console | miner.getHashrate()                             |
| RPC     | {"method": "miner\_getHashrate", "params": \[]} |

### miner\_setExtra <a href="#miner-setextra" id="miner-setextra"></a>

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 <a href="#miner-setgasprice" id="miner-setgasprice"></a>

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\_setRecommitInterval <a href="#miner-setrecommitinterval" id="miner-setrecommitinterval"></a>

Updates the interval for recomitting the miner sealing work.

| CLIENT  | METHOD INVOCATION                                             |
| ------- | ------------------------------------------------------------- |
| Console | miner.setRecommitInterval(interval int)                       |
| RPC     | {"method": "miner\_setRecommitInterval", "params": \[number]} |

### miner\_start <a href="#miner-start" id="miner-start"></a>

Start the CPU mining process.

| CLIENT  | METHOD INVOCATION                         |
| ------- | ----------------------------------------- |
| Go      | miner.Start() error                       |
| Console | miner.start()                             |
| RPC     | {"method": "miner\_start", "params": \[]} |

### miner\_stop <a href="#miner-stop" id="miner-stop"></a>

Stop the CPU mining operation.

| CLIENT  | METHOD INVOCATION                        |
| ------- | ---------------------------------------- |
| Go      | miner.Stop() bool                        |
| Console | miner.stop()                             |
| RPC     | {"method": "miner\_stop", "params": \[]} |

### miner\_setEtherbase <a href="#miner-setetherbase" id="miner-setetherbase"></a>

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 <a href="#miner-setgaslimit" id="miner-setgaslimit"></a>

Sets the gas limit the miner will target when mining. Note: on networks where EIP-1559 is activated, this should be set to twice 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]} |
