Environment Setup

For the simplest installation process, we recommend installing and running go-quai-stratum on the same computer that you're running go-quai. Running go-quai-stratum on a separate computer is for advanced users as it requires additional networking configuration.

Install Dependencies

To run an instance of go-quai-stratum, you'll need to install a few dependencies. You can install dependencies with your favorite package manager (apt, brew, etc.). If you've already installed go-quai, you already have all the necessary dependencies to run go-quai-stratum.

Go v1.21.0+

Snap Install (snapd is not installed by default on all Linux Distros):

sudo apt install snapd

Install go

sudo snap install go --classic

MacOS Install:

brew install go

If you're not on Ubuntu or MacOS, instructions on how to install go directly can be found on the golang installation page.

Git & Make

Linux install:

sudo apt install git make

MacOS install:

brew install git make

Install go-quai-stratum

Now that you've installed the base dependencies, we can go ahead and clone the go-quai-stratum repo.

To clone the go-quai-stratum repo and navigate to it, run the following commands:

git clone https://github.com/dominant-strategies/go-quai-stratum
cd go-quai-stratum

This command installs the main branch to your local machine. Unless you intend to develop, you must checkout the latest release.

You can find the latest release on the go-quai-stratum releases page.

Then, check out the latest release with:

git checkout put-latest-release-here

For example (this not the latest release, check the releases page for the latest release number)

git checkout v01.2.3-rc.4

Configuration

To run the Quai stratum proxy, you'll need to do some minor configuration. Start by copying the example configuration file to a local configuration file.

cp config/config.example.json config/config.json

Within the config.json file, you'll be able to configure networking settings and other relevant variables.

Running the Proxy

Build

Before running the proxy, we need to build the source. You can build via Makefile by running the following command:

make quai-stratum

Run

Now that we've built the source, we can start our proxy We recommend using a process manager program like tmux or screen to run the proxy.

To run the proxy, you'll need to know the web-socket ports utilized by the shard you want to mine within the node. More information on how and why to select shards can be found in our FAQ.

Pass the web-socket ports for the region and zone you'd like to point your proxy at as flags in the run command like so (replace REGION-WS-PORT and ZONE-WS-PORT with the web-socket ports of your desired slice):

./build/bin/quai-stratum --region=REGION-WS-PORT --zone=ZONE-WS-PORT

Do not open the below Web Socket ports EXCEPT in the specific case where your miner is on a different network than your node/stratum (and even then, be sure to only open the port to the necessary machine). You may be putting your local network security at risk.

Running the proxy will only work for chains your node is validating state for. Global nodes validate state for all chains, whereas slice nodes only validate state for the chains you specify.

The proxy by default listens for miner connections on the 3333 port. You can change the port the proxy listens on by passing it in with the --stratum flag in the run command if you'd like.

./build/bin/quai-stratum --region=REGION-WS-PORT --zone=ZONE-WS-PORT --stratum=LISTENING-PORT

Alternatively, you can simply specify the name of ther region and zone you wish to mine to:

./build/bin/quai-stratum --region=tinos --zone=tinos1 --stratum=LISTENING-PORT

Changing the proxy listening port is useful for running multiple proxies on a single full node. If you're only mining on a single shard, there is no need to change the listening port.

The proxy should begin streaming logs to the terminal that look similar to below.

To stop the proxy, use CTRL+C in your terminal. After configuring and pointing your proxy at a shard, you're now ready to point a GPU miner at it and start mining.
