🌐How to setup crossfi node

Recommended Hardware:

  • 4 Cores

  • 8GB RAM

  • 200GB of NVME storage

Installation

  1. Install Dependencies:

    sudo apt update && sudo apt upgrade -y
sudo apt install curl git wget htop tmux build-essential jq make lz4 gcc unzip -y

  2. Install Go:

    cd $HOME
VER="1.21.3"
wget "https://golang.org/dl/go$VER.linux-amd64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$VER.linux-amd64.tar.gz"
rm "go$VER.linux-amd64.tar.gz"
[ ! -f ~/.bash_profile ] && touch ~/.bash_profile
echo "export PATH=$PATH:/usr/local/go/bin:~/go/bin" >> ~/.bash_profile
source $HOME/.bash_profile
[ ! -d ~/go/bin ] && mkdir -p ~/go/bin

  3. Set Environment Variables:

    echo "export WALLET="wallet"" >> $HOME/.bash_profile
echo "export MONIKER="test"" >> $HOME/.bash_profile
echo "export CROSSFI_CHAIN_ID="crossfi-evm-testnet-1"" >> $HOME/.bash_profile
echo "export CROSSFI_PORT="18"" >> $HOME/.bash_profile
source $HOME/.bash_profile

  4. Download and Install the Binary:

    cd $HOME
wget https://github.com/crossfichain/crossfi-node/releases/download/v0.3.0-prebuild3/crossfi-node_0.3.0-prebuild3_linux_amd64.tar.gz
tar -xvf crossfi-node_0.3.0-prebuild3_linux_amd64.tar.gz
chmod +x $HOME/bin/crossfid
mv $HOME/bin/crossfid /usr/local/bin/
rm -rf crossfi-node_0.3.0-prebuild3_linux_amd64.tar.gz $HOME/bin

  5. Configure and Initialize the Application:

    crossfid init $MONIKER
sed -i -e "s|^node *=.*|node = \"tcp://localhost:${CROSSFI_PORT}657\"|" $HOME/.mineplex-chain/config/client.toml

  6. Download Genesis and AddrBook:

    wget -O $HOME/.mineplex-chain/config/genesis.json https://snapshot.pride-nodes.top/crossfi-testnet/genesis.json
wget -O $HOME/.mineplex-chain/config/addrbook.json https://snapshot.pride-nodes.top/crossfi-testnet/addrbook.json

  7. Set Seeds and Peers:

    SEEDS=""
PEERS="de1e9221a35de41e08653ef0aca405c1f2ad500e@crossfi-testnet-peer.pride-nodes.top:19656"
sed -i -e "s/^seeds *=.*/seeds = \"$SEEDS\"/; s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" $HOME/.mineplex-chain/config/config.toml

  8. Customize Ports in app.toml:

    sed -i.bak -e "s|:1317|:${CROSSFI_PORT}317|g;
s|:8080|:${CROSSFI_PORT}080|g;
s|:9090|:${CROSSFI_PORT}090|g;
s|:9091|:${CROSSFI_PORT}091|g;
s|:8545|:${CROSSFI_PORT}545|g;
s|:8546|:${CROSSFI_PORT}546|g;
s|:6065|:${CROSSFI_PORT}065|g" $HOME/.mineplex-chain/config/app.toml

  9. Customize Ports in config.toml:

    sed -i.bak -e "s|:26658|:${CROSSFI_PORT}658|g;
s|:26657|:${CROSSFI_PORT}657|g;
s|:6060|:${CROSSFI_PORT}060|g;
s|:26656|:${CROSSFI_PORT}656|g;
s|^external_address = \"\"|external_address = \"$(wget -qO- eth0.me):${CROSSFI_PORT}656\"|g;
s|:26660|:${CROSSFI_PORT}660|g" $HOME/.mineplex-chain/config/config.toml

  10. Configure Pruning:

    sed -i -e "s/^pruning *=.*/pruning = \"custom\"/" $HOME/.mineplex-chain/config/app.toml
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"100\"/" $HOME/.mineplex-chain/config/app.toml
sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"50\"/" $HOME/.mineplex-chain/config/app.toml

  11. Set Minimum Gas Price, Enable Prometheus & Disable Indexing:

    sed -i 's|minimum-gas-prices =.*|minimum-gas-prices = "10000000000000mpx"|g' $HOME/.mineplex-chain/config/app.toml
sed -i -e "s/prometheus = false/prometheus = true/" $HOME/.mineplex-chain/config/config.toml
sed -i -e "s/^indexer *=.*/indexer = \"null\"/" $HOME/.mineplex-chain/config/config.toml

  12. Create a Service File:

    sudo tee /etc/systemd/system/crossfid.service > /dev/null <<EOF
[Unit]
Description=Crossfi node
After=network-online.target
[Service]
User=$USER
WorkingDirectory=$HOME/.mineplex-chain
ExecStart=$(which crossfid) start --home $HOME/.mineplex-chain
Restart=on-failure
RestartSec=5
LimitNOFILE=65535
[Install]
WantedBy=multi-user.target
EOF

  13. Reset and Download Snapshot:

    crossfid tendermint unsafe-reset-all --home $HOME/.mineplex-chain

  14. Enable and Start the Service:

    sudo systemctl daemon-reload
sudo systemctl enable crossfid
sudo systemctl restart crossfid && sudo journalctl -u crossfid -f

Wallet Setup

  • Create a Wallet:

    crossfid keys add $WALLET

  • Restore an Existing Wallet:

    crossfid keys add $WALLET --recover

  • Save Wallet and Validator Addresses:

    WALLET_ADDRESS=$(crossfid keys show $WALLET -a)
VALOPER_ADDRESS=$(crossfid keys show $WALLET --bech val -a)
echo "export WALLET_ADDRESS=\"$WALLET_ADDRESS\"" >> $HOME/.bash_profile
echo "export VALOPER_ADDRESS=\"$VALOPER_ADDRESS\"" >> $HOME/.bash_profile
source $HOME/.bash_profile

  • Check Sync Status:

    crossfid status 2>&1 | jq

  • Check Wallet Balance:

    crossfid query bank balances $WALLET_ADDRESS

Validator Setup

  • Create a Validator:

    crossfid tx staking create-validator \
--amount 1000000mpx \
--from $WALLET \
--commission-rate 0.1 \
--commission-max-rate 0.2 \
--commission-max-change-rate 0.01 \
--min-self-delegation 1 \
--pubkey $(crossfid tendermint show-validator) \
--moniker $MONIKER \
--identity "" \
--website "" \
--details "a validator blockchain" \
--chain-id crossfi-evm-testnet-1 \
--gas auto \
--gas-adjustment 1.5 \
--gas-prices 10000000000000mpx \
-y
