# 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]} |

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://developer.electroneum.com/etn-sc-client/interacting-with-etn-sc/json-rpc-namespaces/miner.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
