Prerequisites

• Go v1.21.0+
• Git
• Make

For details on installing prerequisites, visit the node installation instructions in the Quai Documentation.

Building the source

Once you have the necessary prerequisites, clone the go-quai repository and navigate to it using:

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

Next, you will need to copy the boilerplate node configuration file (network.env.dist) into a configuration file called network.env. You can do this by running:

$ cp network.env.dist network.env

Building go-quai requires both a Go (version 1.21.0+ or later) and a C compiler. You can install them using your favorite package manager. Once these dependencies are installed, run:

$ make go-quai

or, to build the full suite of utilities:

$ make all

Executables

The go-quai project comes with several wrappers/executables found in the cmd directory.

go-quai

Our main Quai CLI client. go-quai is the entry point into the Quai network (main-, test-, or private net), capable of running as a slice node (single slice), multi-slice node (subset of slices), and a global node (all slices). Each of these types of nodes can be run as full node (default), a light node (retrieving data live), or an archive node (retaining all historical state).

go-quai can be used by other processes as a gateway into the Quai network via JSON RPC endpoints exposed on top of HTTP, WebSocket and/or IPC transports.

go-quai --help for command line options.

go-quai Nodes	Single Slice	Multiple Slices	All Slices
Full Node	Slice Full Node (Default)	Multi-Slice Full Node	Global Full Node
Light Nodes	Slice Light Node	Multi-Slice Light Node	Global Light Node
Archive Node	Slice Archive Node	Multi-Slice Archive Node	Global Archive Node

test

Runs a battery of tests on the repository to ensure it builds and functions correctly.

Running go-quai

Configuration

Configuration is handled in the network.env file. You will need to copy or rename the file to network.env. The make commands will automatically pull from this file for configuration changes.

The default configuration of the network.env file is for a global full node on the main (colosseum) network.

• The SLICES parameter determines which slices of the network the node will run (i.e. determines whether the node will be a slice node, a multi-slice node, or a global node).

• The COINBASE paratmeter contains the addresses that mining rewards will be paid to. There is one COINBASE address for each slice.

• The NETWORK parameter determines the network that the node will run on. Networks include the mainnet (colosseum) and garden networks.

Starting and stopping a node

The go-quai client can be started by using:

$ make run

Using the makefile will preload configuration values from the network.env file.

The go-quai client can be stopped by using:

$ make stop

Viewing logs

Logs are stored in the go-quai/nodelogs directory by default. You can view them by using tail or another utility, like so:

$ tail -f nodelogs/zone-X-Y.log

X and Y should be replaced with values between 0-2 to define which slice's logs to display.

Garden test network

The Garden test network is based on the Blake3 proof-of-work consensus algorithm. As such, it has certain extra overhead and is more susceptible to reorganization attacks due to the network's low difficulty/security.

To run on the Garden test network, modify the network.env configuration file to reflect NETWORK=garden. You should also set ENABLE_ARCHIVE=true to make sure to save the trie-nodes after you stop your node. Then build and run with the same commands as mainnet.

Contribution

Thank you for considering to help out with the source code! We welcome contributions from anyone on the internet, and are grateful for even the smallest of fixes.

If you'd like to contribute to go-quai, please fork, fix, commit and send a pull request for the maintainers to review and merge into the main code base.

Please make sure your contributions adhere to our coding guidelines:

• Code must adhere to the official Go formatting guidelines (i.e. uses gofmt).
• Code must be documented adhering to the official Go commentary guidelines.
• Pull requests need to be based on and opened against the main branch.
• Commit messages should be prefixed with the package(s) they modify.
  • E.g. "rpc: make trace configs optional"

If you wish to submit more complex changes, please check up with the core devs first in the Quai development Discord Server to ensure your changes are in line with the general philosophy of the project and/or get some early feedback which can make both your efforts much lighter as well as our review and merge procedures quick and simple.
