Network.Bitcoin.Mining

Description

An interface to bitcoind's available mining RPC calls. The implementation of these functions can be found at https://github.com/bitcoin/bitcoin/blob/master/src/rpcmining.cpp.

If any APIs are missing, patches are always welcome. If you look at the source of this module, you'll see that the interface code is trivial.

Note that it is highly discouraged to use bitcoind for actual bitcoin mining. It uses the CPU for mining, which is much, much less power efficient than GPU mining. If you're paying for power, you will not come out ahead.

Instead, consider using a GPU miner listed at https://en.bitcoin.it/wiki/Software#Mining_apps.

Documentation

type Client = ByteString -> IO ByteString Source #

Client describes authentication credentials and host info for making API requests to the Bitcoin daemon.

getClient :: String -> ByteString -> ByteString -> IO Client Source #

getClient takes a url, rpc username, and rpc password and returns a Client that can be used to make API calls. Each Client encloses a Manager (from http-client) that re-uses connections for requests, so long as the same Client is is used for each call.

getGenerate Source #

Arguments

:: Client	bitcoind RPC client
-> IO Bool

Returns whether or not bitcoind is generating bitcoins.

setGenerate Source #

Arguments

:: Client	bitcoind RPC client
-> Bool	Turn it on, or turn it off?
-> Maybe Int	Generation is limited to this number of processors. Set it to Nothing to keep the value at what it was before, Just -1 to use all available cores, and any other value to limit it. If bitcoind runs in regtest mode instead of the number of processors, this specifies the number of hashes to generate.
-> IO (Maybe [HexString])

Controls whether or not bitcoind is generating bitcoins. If bitcoind runs in regtest mode the number of generated hashes is returned. See https://bitcoin.org/en/developer-reference#setgenerate for more details.

generate Source #

Arguments

:: Client
-> Int	The number of blocks to generate. The RPC call will not return until all blocks have been generated or the maxium number of iterations has been reached
-> Maybe Int	The maximum number of iterations that are tried to create the requested number of blocks. Default is 1000000
-> IO [HexString]	An array containing the block header hashes of the generated blocks (may be empty if used with generate 0)

The generate RPC nearly instantly generates blocks. See https://bitcoin.org/en/developer-reference#generate for more details.

generateToAddress Source #

Arguments

:: Client
-> Int	The number of blocks to generate. The RPC call will not return until all blocks have been generated or the maxium number of iterations has been reached
-> Address	The address to send the newly generated Bitcoin to
-> Maybe Int	The maximum number of iterations that are tried to create the requested number of blocks. Default is 1000000
-> IO [HexString]

The generatetoaddress RPC mines blocks immediately to a specified address. See https://bitcoin.org/en/developer-reference#generatetoaddress for more details.

getHashesPerSec :: Client -> IO Integer Source #

Returns a recent hashes per second performance measurement while generating.

data MiningInfo Source #

Information related to the current bitcoind mining operation.

If a field is undocumented here, it's because I don't know what it means. If you DO know what it means, I'd love it if you would submit a patch to help complete this documentation.
