The `miner` API is **now deprecated** because mining was switched off at the transition to proof-of-stake. It existed to provide remote control the node's mining operation and set various mining specific settings. It is provided here for historical interest!

## miner_getHashrate {#miner-hashrate}

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

| Client  | Method invocation                               |
| :------ | ----------------------------------------------- |
| Console | `miner.getHashrate()`                           |
| RPC     | `{"method": "miner_getHashrate", "params": []}` |

## miner_setExtra {#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 {#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_setRecommitInterval {#miner-setrecommitinterval}

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 {#miner-start}

Start the CPU mining process.

| Client  | Method invocation                         |
| :------ | ----------------------------------------- |
| Go      | `miner.Start() error`             |
| Console | `miner.start()`                           |
| RPC     | `{"method": "miner_start", "params": []}` |

## miner_stop {#miner-stop}

Stop the CPU mining operation.

| Client  | Method invocation                        |
| :------ | ---------------------------------------- |
| Go      | `miner.Stop() bool`                      |
| Console | `miner.stop()`                           |
| RPC     | `{"method": "miner_stop", "params": []}` |

## miner_setEtherbase {#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 {#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 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]}` |
