Node installation

Currently, to run a node, you need to run two separate clients:

• zenrockd, consensus client

• zenrock-sidecar, oracle

# if necessary, create the go/bin/ directory
mkdir -p $HOME/go/bin/

cd $HOME
mkdir -p zenrock && cd zenrock

Install zenrock

cd $HOME/zenrock
wget https://github.com/zenrocklabs/zrchain/releases/download/v5.3.4/zenrockd
chmod +x zenrockd
mv $HOME/zenrock/zenrockd $HOME/go/bin/

zenrockd version --long | grep -e version -e commit
# version: 5.3.4
# commit: 4bcdf8ab99b43e0ff183bb9f3207d6e50ea14ea6

Initialize the node to create the necessary configuration files

zenrockd init UTSA_guide --chain-id gardia-2

Genesis

curl -s https://rpc.gardia.zenrocklabs.io/genesis | jq .result.genesis > $HOME/.zrchain/config/genesis.json

# check genesis
sha256sum ~/.zrchain/config/genesis.json
# 85baddb3e1cb6b349aee2d79050b88f781ee34c0d0fc51d9ee2fecd04877ca3c

Download Addr book

wget -O $HOME/.zrchain/config/addrbook.json "https://share106-7.utsa.tech/zenrock/addrbook.json"

Setting up the node configuration

zenrockd config set client chain-id gardia-2
#zenrockd config set client keyring-backend test
