--- title: miner Namespace description: Documentation for the JSON-RPC API "miner" namespace --- 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 Get 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_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 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 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]}` |
