Miner Methods

miner_getHashrate​

Private: Requires authentication.

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

Proof-of-Work specific. This endpoint always returns 0.

// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"miner_setGasPrice","params":[],"id":1}' -H "Content-Type: application/json" http://localhost:8545

// Result
{"jsonrpc":"2.0","id":1,"result":0}

miner_setExtra​

Private: Requires authentication.

Sets the extra data a validator can include when proposing blocks. This is capped at 32 bytes.

Unsupported. This endpoint always returns an error

Parameters​

  • Data
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"miner_setExtra","params":["data"],"id":1}' -H "Content-Type: application/json" http://localhost:8545

// Result
{"jsonrpc":"2.0","id":1,"result":false}

miner_setGasPrice​

Private: Requires authentication.

Sets the minimal gas price used to accept transactions. Any transaction below this limit is excluded from the validator block proposal process.

This method requires a node restart after being called because it changes the configuration file.

Make sure your treasurenetd start call is not using the flag minimum-gas-prices because this value will be used instead of the one set on the configuration file.

Parameters​

  • Hex Gas Price
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"miner_setGasPrice","params":["0x0"],"id":1}' -H "Content-Type: application/json" http://localhost:8545

// Result
{"jsonrpc":"2.0","id":1,"result":true}

miner_start​

Private: Requires authentication.

Start the CPU validation process with the given number of threads.

Unsupported. This endpoint always returns an error

Parameters​

  • Hex Number of threads
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"miner_start","params":["0x1"],"id":1}' -H "Content-Type: application/json" http://localhost:8545

// Result
{"jsonrpc":"2.0","id":1,"result":false}

miner_stop​

Private: Requires authentication.

Stop the validation operation.

Unsupported. This endpoint always performs a no-op.

// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"miner_stop","params":[],"id":1}' -H "Content-Type: application/json" http://localhost:8545

miner_setGasLimit​

Private: Requires authentication.

Sets the gas limit the miner will target when mining. Note: on networks where EIP-1559 (opens new window)is activated, this should be set to twice what you want the gas target (i.e. the effective gas used on average per block) to be.

Unsupported. This endpoint always returns false

Parameters​

  • Hex gas limit
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"miner_setGasLimit","params":["0x10000"],"id":1}' -H "Content-Type: application/json" http://localhost:8545

// Result
{"jsonrpc":"2.0","id":1,"result":false}

miner_setEtherbase​

Private: Requires authentication.

Sets the etherbase. It changes the wallet where the validator rewards will be deposited.

Parameters​

  • Account Address
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"miner_setEtherbase","params":["0x3b7252d007059ffc82d16d022da3cbf9992d2f70"],"id":1}' -H "Content-Type: application/json" http://localhost:8545

// Result
{"jsonrpc":"2.0","id":1,"result":true}
