sudo tar -C /usr/local -xzf go1.22.2.linux-amd64.tar.gz
rm go1.22.2.linux-amd64.tar.gz
echo 'export PATH=$PATH:/usr/local/go/bin' >> $HOME/.bashrc
echo 'export PATH=$PATH:$HOME/go/bin' >> $HOME./bashrc
source $HOME/.bashrc
 
# Install cosmovisor
go install cosmossdk.io/tools/cosmovisor/cmd/[email protected]
sudo mv ~/go/bin/cosmovisor /usr/local/bin

Clone the repository and install node binary

cd $HOME 
git clone https://github.com/LightLABS-Dev/prysm.git
cd prysm 
git checkout v0.1.0 # always doublecheck from the official team for the right version
make install

Set up cosmovisor

mkdir -p $HOME/.prysm/cosmovisor/genesis/bin
mkdir -p $HOME/.prysm/cosmovisor/upgrades
mv $HOME/go/bin/prysmd $HOME/.prysm/cosmovisor/genesis/bin/
sudo ln -s $HOME/.prysm/cosmovisor/genesis $HOME/.prysm/cosmovisor/current -f
sudo ln -s $HOME/.prysm/cosmovisor/current/bin/prysmd /usr/local/bin/prysmd -f

Set up the node

# Please when using this guide replace “YOUR_MONIKER” with name for your node.
 
prysmd init YOUR_MONIKER --chain-id prysm-devnet-1
 
# Get address book and genesis.json
wget https://raw.githubusercontent.com/Cogwheel-Validator/docs/main/files/prysm-testnet/genesis.json -O $HOME/.prysm/config/genesis.json
wget https://raw.githubusercontent.com/Cogwheel-Validator/docs/main/files/prysm-testnet/addrbook.json -O $HOME/.prysm/config/addrbook.json
 
#Set minimum gas prices
sed -i -e “s|^minimum-gas-prices *=.*|minimum-gas-prices = \”0uprysm\”|” $HOME/.prysm/config/app.toml

Use snapshot or state sync to catch up.

Links to snapshots. You only need from one provider.
