Running go-quai on Windows or WSL2 is not currently supported.

Requirements

To run a Quai Network node, the following specifications are suggested:

Fast CPU with 16+ cores

64GB+ RAM

Fast SSD with at least 3TB free space

10+ MBit/sec download Internet service

Install Dependencies

Go v1.23.0+

Snap is not default installed on all Linux distros

  # install snapd if you don't have it already
  sudo apt install snapd

  # install go
  sudo snap install go --classic

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, and G++

Install git, make, and g++ with the following command:

# install git and make
sudo apt install git make g++

Node Configuration

Start

Mainnet (Colosseum)

# Clone go-quai and checkout latest release
git clone https://github.com/dominant-strategies/go-quai
cd go-quai
git checkout <latest-tag>
make go-quai

# Start node
./build/bin/go-quai start \
--node.slices '[0 0]' \
--node.quai-coinbases '0x0000000000000000000000000000000000000001' \
--node.qi-coinbases '0x0080000000000000000000000000000000000001' \

Mainnet Testnet (Orchard)

The Orchard testnet requires using the orchard branch of go-quai. Using any other branch or tag will result in sync issues or genesis incompatibility.

# Clone go-quai and checkout orchard branch
git clone https://github.com/dominant-strategies/go-quai
cd go-quai
git checkout orchard
make go-quai

# Start node
./build/bin/go-quai start \
--node.slices '[0 0]' \
--node.genesis-nonce 62242624366553750196964614682162313 \
--node.environment "orchard" \
--node.quai-coinbases '0x0000000000000000000000000000000000000001' \
--node.qi-coinbases '0x0080000000000000000000000000000000000001' \

Local Developer Network

# Clone go-quai and checkout latest release
git clone https://github.com/dominant-strategies/go-quai
cd go-quai
git checkout <latest-tag>
make go-quai # make debug is also available for line by line debugging


# Start node
./build/bin/go-quai start \
--node.slices '[0 0]' \
--node.environment "local" \
--node.quai-coinbases '0x0000000000000000000000000000000000000001' \
--node.qi-coinbases '0x0080000000000000000000000000000000000001' \

The coinbase values above are set to dummy values. If you do not replace them with your own addresses, you will not receive block rewards.

This will spin up a node using the values of the node.slices, node.quai-coinbases, node.qi-coinbases flags in your command. Logs should begin printing to the terminal.

Stop

Stopping your node should be done any time you make changes to your config file or prior to shutting your machine down. A node instance can terminated using CTRL+C.

If you’re running a miner, CTRL+C may not work. You must kill the miner process prior to stopping the node.

Environment Variables

There are a few key variables required to run a Quai node. They will be passed as arguments in the start command.

quai-coinbases and qi-coinbases: the addresses in each ledger that block rewards and miner tips are paid to.
miner-preference: the percentage of block rewards that should be paid out on average in Quai or Qi tokens.
slices: the slices of the network that the node will run.

There are a number of more advanced parameters that can be passed as arguments that will not be covered in this article.

Configure Mining Addresses

Coinbases will be passed to the start command similar to below, with your own addresses for the chains that you intend to mine. You can generate addresses for each shard and ledger easily with Pelagus Wallet.You must generate unique Quai and Qi addresses for each shard your node is running and pass them as coinbase flags to the run command. There is a unique coinbases flag for each ledger:

quai-coinbases: Coinbases for Quai ledger
qi-coinbases: Coinbases for Qi ledger

# single slice node running cyprus1, one quai address + one qi address
--node.quai-coinbases '0x0000000000000000000000000000000000000000'
--node.qi-coinbases '0x0080000000000000000000000000000000000000'

The Qi mining address starts with a “0x00…”, this is not to be confused with the Qi payment address. You can find the Qi mining address in the settings of the Pelagus Wallet.

Block Reward Prefernce

The Quai protocol can payout block rewards and miner tips in either Quai or Qi tokens. While miners have no ability to determine what token their miner tips are paid out in, the do have the ability to set their block reward payout token preference to either Quai or Qi.Block reward token preference can be set using the miner-preference flag. The miner-preference flag is a percentage scale that can be set to values between 0 and 1, indicating the proportion of block rewards that should be paid out in Quai or Qi tokens.Some examples:

0: 100% Quai preference, all block rewards are paid out in Quai
0.25: 3/1 Quai preference
0.5: Even split, on average block rewards are paid out equally in Quai and Qi
0.75: 3/1 Qi preference
1: 100% Qi preference, all block rewards are paid out in Qi

Pass the miner-preference flag in the start command with a value between 0 and 1 like below:

# no preference (default)
--node.miner-preference 0.5

# 100% Quai preference
--node.miner-preference 0

# 100% Qi preference
--node.miner-preference 1

Reward Lockup Period

The Quai protocol immediately pays out block rewards as blocks are mined, but are subject to a lockup period.

Quai Block rewards are sent to the coinbase of the miner after the lockup period has elapsed.
Qi Block reward tokens are sent to the coinbase of the miner and register as balance, but are deemed “not spendable” until they are unlocked.

The lockup period is configurable by miners using the --node.coinbase-lockup flag. The protocol provides additional incentives for miners to lock up their block rewards for a longer period of time.The available values for --node.coinbase-lockup and their corresponding period and reward boost are:

Value	Period (blocks)	Period (days)	Reward Boost
`0*`	241,920	2 weeks	+0%
`1`	1,555,200	3 months	+3.5%
`2`	3,110,400	6 months	+10%
`3`	6,220,800	12 months	+25%

_{*Base maturity period}Pass the --node.coinbase-lockup flag in the start command like below:

# minimum lockup (default)
--node.coinbase-lockup 0

# maximum lockup
--node.coinbase-lockup 3

Slices

Set the node.slices flag in your run command to whichever slices of the network you would like to run.In the codebase, a slice is identified by its region and zone index. Region and zone indices are 0-indexed and range from 0-2.

The Colosseum Mainnet and Orchard Testnet only support the [0 0] slice.

# single slice node running cyprus1
--node.slices '[0 0]'

Network Environment & Genesis Nonce

To connect to Quai, you must have the correct genesis nonce for the intended network. The nonce acts as a password that allows your node to correctly compute the first canonical block in the chain.You’ll pass the genesis nonce to your node on start-up using the --node.genesis-nonce flag.

# Orchard Testnet geneis nonce
--node.genesis-nonce 62242624366553750196964614682162313
--node.environment "orchard"

Options for --node.environment are: "colosseum" (mainnet), "orchard" (mainnet testnet), "garden" (mainnet devnet), and "local".

Environment	Description	Genesis Nonce
`colosseum`	Mainnet	23621466532946281564673705261963422
`orchard`	Mainnet testnet	62242624366553750196964614682162313
`local`	Local development	N/A

Other Node Operations

Check log output

Starting a node will run all instances of go-quai in the foreground and also create a directory named nodelogs to store more specific logs from the node. Outputs from the node will be piped to a context specific .log file inside of the nodelogs directory. To view the log output for a specific location, use:

# view global logs (recommended)
tail -f nodelogs/global.log

# view specific region or zone logs
tail -f nodelogs/region-0.log
# OR
tail -f nodelogs/zone-0-0.log

Checking the node logs output is the best way to verify that your full node is running correctly. You can also easily view node logs in your favorite IDE or text editor.The outputs of a node that has started correctly should look similar to below.

INFO   [10-02|19:42:12.077] Loading config from file: /root/.config/go-quai/config.toml

To stop log outputs to the terminal, you can use CTRL+C.

Depending on what your node is currently doing, your logs may not look exactly the same as above.

Checking sync progress

If your node has started correctly, it will begin syncing chain state from peers. There are a few ways to check the progress of the sync.From the command line, we can run the following command(s) to print the list of blocks that have been appended. Replace location-to-print-here.log with the file name of the logs you’d like to print.

# Print all appended blocks
cat nodelogs/location-to-print-here.log | grep Appended

# Continuously print new appended blocks
tail -f nodelogs/location-to-print-here.log | grep Appended

# Continuously print appended blocks across all chains
tail -f nodelogs/* | grep Appended

The output should look similar to below:

INFO   [09-18|10:18:17.273] Appended new block                       number=[102 1934 40392] hash=0x0000067368b679ce7994dbd6e3dfe93a5e5fe16642a6083604fd405556836cbe difficulty=405369 uncles=0 txs=0 etxs=0 gas=0 gasLimit=5000000 root=0x7df4c77d1463a5e4c7d5f5446476e34df01cf14b6226b7d83ccab072bc302edc order=2 location=[0 0] elapsed=2.019ms

To check the progress of your node’s sync, compare the number of the latest block output from the above command to the current height of the chain you’re running on the Quai node stats page.

If your node temporarily stops appending during sync, do not stop it. Allow it to continue running, and only reach out for support if the node has not appended a block for over 1 hour.

Update

Initiating the node update process while the node or manager are currently running could cause issues. Make sure to stop all processes before updating.

To update a node, first make sure to stop all instances of go-quai before proceeding.After stopping the node, you should pull any updated code using:

git fetch --all

Checkout the latest release of go-quai:

git checkout put-latest-release-here

Finally, rebuild the source using:

make go-quai

After pulling any new code and rebuilding the source, you can safely restart the node and continue running.

Reset and clear

Resetting your node and clearing your database will remove any state you have synced. This is a non-reversible action and any commands noted below should be utilized with caution.

Developers and node runners may find that situations arise where they need to completely clear your node of synced state or do a full reset in the case of an issue or bug. A full reset of a node involves stopping the node, clearing the current nodelogs, and removing all synced state.Reminder, resetting your node is non-reversible and should only be done if you understand the implications of removing all synced state.

For Linux Machines, we’ll remove the nodelogs directory and the base ~/.local/share/go-quai directory which contains all synced state. To do this, run the following command:

rm -rf nodelogs ~/.local/share/go-quai

After running the above command, the node has been fully reset and is ready to be restarted.

Create Backup/Snapshot

You can create your own backup or snapshot to:

Store for later.
Move to another machine.

Shut down the node cleanly. You can use ctrl+c.

Remove the peer db. It is stored in the genesis hash folder.

# Linux
rm -rf ~/.local/share/go-quai/0xd0c4fae4dc06d3558c7631f6665cca93931cfc8891729fe1bdaa1024b0db9c98

# MacOS
rm -rf ~/Library/Application\ Support/go-quai/0xd0c4fae4dc06d3558c7631f6665cca93931cfc8891729fe1bdaa1024b0db9c98

Compress the database for smaller storage and faster transfers.
tar -I zstd -cvf mainnet-snapshot.tar.zst ~/.local/share/go-quai

Download and Sync from Snapshot

Common reasons for syncing from a snapshot include:

Reducing syncing times
Restarting a node on a new machine/drive

Please be aware that when you are syncing from a snapshot, you are trusting the contents of the snapshot. For your node to fully verify the network, you must sync from genesis.

To restore your node’s database from a snapshot you’ll first need to stop your node. You can then download the latest official snapshot from the official snapshot link or from the CLI by running the command below. The link will be added and periodically updated here once the first snapshot for Quai Mainnet is taken.

wget https://storage.googleapis.com/colosseum-db/mainnet-snapshot.tar.zst

To restore your database from a snapshot, use:

  # Remove current db
  # This command will permanently delete all state that you have synced thus far
  rm -rf ~/.local/share/go-quai

  # Expand compressed db
  tar -I 'zstd -T0' -xvf mainnet-snapshot.tar.zst

  # Copy db into db directory
  cp -r mainnet-snapshot ~/.local/share/go-quai
