Install

Environment setup

Install the necessary libraries for the build.

cd $HOME
sudo apt update -y; sudo apt upgrade -y
sudo apt install -y jq git build-essential

Install Go. Use the 20.x series version.

$ wget https://go.dev/dl/go1.20.linux-amd64.tar.gz
$ sudo rm -rf /usr/local/go && sudo tar -C /usr/local -xzf go1.20.linux-amd64.tar.gz
$ vim ~/.bashrc
export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin
$ source ~/.bashrc
$ go version
go version go1.20 linux/amd64

Clone the UnUniFi blockchain repository, check out the given branch, and build it with make install to build binaries.

git clone https://github.com/UnUniFi/chain chain_repo
cd chain_repo
git checkout v3.2.0
git pull
make install

Check the binary version.

ununifid version

Start node for debugging

Initialize node

ununifid init [your-moniker] --chain-id [chain-id]
  • your-moniker is like a nickname of your node.
  • chain-id is the id of the blockchain network. (ex. In the current mainnet beta, the chain-id is ununifi-beta-v1.)

Download correct genesis.json

rm ~/.ununifi/config/genesis.json
curl -L https://raw.githubusercontent.com/UnUniFi/network/main/launch/[chain-id]/genesis.json -o ~/.ununifi/config/genesis.json

If you necessary, Edit config files.

  • ~/.ununifi/config/app.toml
  • .ununifi/config/config.toml ex. in the case of chain-id="ununifi-beta-v1", the possible settings are as follows.
    • persistent-peers = "fa38d2a851de43d34d9602956cd907eb3942ae89@a.ununifi.cauchye.net:26656,404ea79bd31b1734caacced7a057d78ae5b60348@b.ununifi.cauchye.net:26656,1357ac5cd92b215b05253b25d78cf485dd899d55@[2600:1f1c:534:8f02:7bf:6b31:3702:2265]:26656,25006d6b85daeac2234bcb94dafaa73861b43ee3@[2600:1f1c:534:8f02:a407:b1c6:e8f5:94b]:26656,caf792ed396dd7e737574a030ae8eabe19ecdf5c@[2600:1f1c:534:8f02:b0a4:dbf6:e50b:d64e]:26656,796c62bb2af411c140cf24ddc409dff76d9d61cf@[2600:1f1c:534:8f02:ca0e:14e9:8e60:989e]:26656,cea8d05b6e01188cf6481c55b7d1bc2f31de0eed@[2600:1f1c:534:8f02:ba43:1f69:e23a:df6b]:26656"

Start node.

ununifid start

Keep your node stable

If you wanna keep your node stable, we recommend to use Cosmovisor.

https://docs.cosmos.network/master/run-node/cosmovisor.html

Setup

Set the following environment variables. Some environment variables must be set to appropriate values for each node and each network.

~/.profile

export CHAIN_REPO=https://github.com/UnUniFi/chain
export CHAIN_REPO_BRANCHE=main
export TARGET=ununifid
export TARGET_HOME=.ununifi

# This value will be different for each node.
export MONIKER=<your-moniker>
export DL_CHAIN_BIN=

# This value is example of mainnet.
export CHAIN_ID=ununifi-beta-v1

# This value is example of mainnet.
export GENESIS_FILE_URL=https://raw.githubusercontent.com/UnUniFi/network/main/launch/ununifi-beta-v1/genesis.json
export SETUP_NODE_CONFIG_ENV=TRUE
export SETUP_NODE_ENV=TRUE
export SETUP_NODE_MASTER=TRUE
export DAEMON_NAME=ununifid

# This value will be different for each node.
export DAEMON_HOME=/home/<your-user>/.ununifi
export DAEMON_ALLOW_DOWNLOAD_BINARIES=true
export DAEMON_LOG_BUFFER_SIZE=512
export DAEMON_RESTART_AFTER_UPGRADE=true
export UNSAFE_SKIP_BACKUP=true

Install Cosmovisor

cd $HOME
go install github.com/cosmos/cosmos-sdk/cosmovisor/cmd/cosmovisor@v1.0.0
mkdir -p $DAEMON_HOME/cosmovisor
mkdir -p $DAEMON_HOME/cosmovisor/genesis
mkdir -p $DAEMON_HOME/cosmovisor/genesis/bin
mkdir -p $DAEMON_HOME/cosmovisor/upgrades
cp ~/go/bin/$DAEMON_NAME $DAEMON_HOME/cosmovisor/genesis/bin

Register daemon service

Create service file.

/lib/systemd/system/cosmovisor.service

Set systemctl

sudo systemctl daemon-reload
sudo systemctl restart systemd-journald
sudo systemctl enable cosmovisor

Start node with cosmovisor

Start node.

sudo systemctl start cosmovisor

You can check your node status with the following command.

$ sudo systemctl status cosmovisor
