Prior to installation, you'll need to install the necessary dependencies.
sudo apt-get install git cmake build-essential libssl-dev
On macOS, installing gcc is required to support OpenMP parallelization. Using the brew package manager, install OpenSSL and gcc.
brew install openssl gcc cmake
On Windows, ensure that you are using the MingW compiler and you have installed CMake. Using the cholocately package manager, install OpenSSL.
choco install openssl
For both Windows and Linux, you should be able to simply invoke the standard npm installer.
npm install
For macOS, you will need to specify the C compiler as gcc.
CC=gcc-10 npm install
You can view the CLI miner arguments by using npm like so:
npm start -- --help
And get the following output:
❯ npm start -- --help
> koinos-miner@1.0.0 start /path/to/koinos-miner
> node app.js "--help"
Usage: app [OPTIONS]...
Options:
-v, --version output the version number
-a, --addr <addr> An ethereum address
-e, --endpoint <endpoint> An ethereum endpoint (default: "wss://ropsten-rpc.linkpool.io/ws")
-t, --tip <percent> The percentage of mined coins to tip the developers (default: "5")
-p, --proof-period <seconds> How often you want to submit a proof on average (default: "86400")
-k, --key-file <file> AES encrypted file containing private key
-m, --gas-multiplier <multiplier> The multiplier to apply to the recommended gas price (default: "1")
-l, --gas-price-limit <limit> The maximum amount of gas to be spent on a proof submission (default: "1000000000000")
--import Import a private key
--export Export a private key
-h, --help display help for command
Recipient Address: The --addr argument specifies the recipient address, this is where KOIN will be rewarded.
Ethereum Endpoint: The --endpoint argument specifies the Ethereum node to be used when querying contract information and submitting proofs.
Developer Tip: The --tip argument specifies the percentage of rewarded KOIN to donate to the development team, thank you!
Proof Period: The --proof-period argument specifies the number of seconds on average the miner will attempt to mine and submit proofs.
Gas Multiplier: The --gas-multiplier argument specifies a multiplier to apply to the calculated gas price. This can be used to get your proofs submitted when the Ethereum network gas fees are spiking or are unpredictable.
Gas Price Limit: The --gas-price-limit argument specifies a cap in the acceptable gas price for a proof submission.
A more detailed explanation of the different miner configurations can be found in the Koinos GUI Miner README.md.
The CLI miner provides the arguments --import, --export, and --key-file. These are used in handling the private key of the funding address. The user may import a private key and optionally store it in a key file in which case exporting the key is now possible.
A simple example of running the miner:
❯ npm start -- --endpoint http://167.172.118.40:8545 --addr 0x98047645bf61644caa0c24daabd118cc1d640f62 --import
> koinos-miner@1.0.0 start /path/to/koinos-miner
> node app.js "--endpoint" "http://167.172.118.40:8545" "--addr" "0x98047645bf61644caa0c24daabd118cc1d640f62" "--import"
