JSON-RPC Namespaces - miner

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

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.

CLIENT METHOD INVOCATION
Go miner.Start() error
Console miner.start()
RPC {“method”: “miner_start”, “params”: }

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]}
