๐Ÿ“š Node installation

Update packages

sudo apt update && sudo apt upgrade -y

Install dependencies

sudo apt install curl tar wget clang pkg-config libssl-dev libleveldb-dev jq build-essential bsdmainutils git make ncdu htop screen unzip bc lz4 gcc -y

Install Go

cd $HOME && \
ver="{{goVersion}}" && \
wget "https://golang.org/dl/go$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" && \
echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.bash_profile && \
source $HOME/.bash_profile && \
go version

The output should be: go version go{{goVersion}} linux/amd64

Download binary for work

git clone {{binaryUrl}}
cd {{dirName}}
git checkout {{nodeVersion}}
make install

Specify variables, for ease of work

echo 'export {{chainName}}_moniker="Validator_name"' >> $HOME/.profile
echo 'export {{chainName}}_wallet="Wallet_name"' >> $HOME/.profile
echo 'export {{chainName}}_port="111"' >> $HOME/.profile
source $HOME/.profile

Initialize the node

{{appName}} init ${{chainName}}_moniker --chain-id {{chainId}}

Set the settings

{{appName}} config chain-id {{chainId}} && \
peers={{peersChain}} && \
sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \"$peers\"/" $HOME/.{{dirName}}/config/config.toml && \
seeds="6b0ffcce9b59b91ceb8eea5d4599e27707e3604a@seeds.stakeup.tech:10217" && \
sed -i.bak -e "s/^seeds =.*/seeds = \"$seeds\"/" $HOME/.{{dirName}}/config/config.toml

Create wallet

{{appName}} keys add ${{chainName}}_wallet

Save the wallet. Or restore if there is a mnemonic:

{{appName}} keys add ${{chainName}}_wallet --recover

Download Genesis

wget -O genesis.json "https://snapshots.stakeup.tech/{{chainName}}/genesis.json" --inet4-only
mv genesis.json ~/.{{dirName}}/config
