💻Installation Consensus Node

Server preparation

apt update && apt upgrade -y

apt install curl iptables build-essential git wget jq make gcc nano tmux htop nvme-cli pkg-config libssl-dev libleveldb-dev tar clang bsdmainutils ncdu unzip libleveldb-dev -y

Install GO

ver="1.20.2"
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

Node installation

git clone https://github.com/celestiaorg/celestia-app && cd celestia-app
git checkout v0.13.0
make install

celestia-appd version --long | grep -e version -e commit -e build
# version 0.13.0
# commit 6ba60e18fec27d3e3a42a71be082e255913cf4cf
# build_tags: ""

We initialize the node to create the necessary configuration files

cd $HOME
git clone https://github.com/celestiaorg/networks
celestia-appd init UTSA_gude --chain-id blockspacerace-0

Download Genesis

cp $HOME/networks/blockspacerace/genesis.json $HOME/.celestia-app/config

# Проверим генезис
sha256sum ~/.celestia-app/config/genesis.json
# 877046754f4e730b75c72fea2ffdbf79a1663edbf40a86a838321a163322a7ae

At this stage, we can download the address book

wget -O $HOME/.celestia-app/config/addrbook.json "https://snapshots.kjnodes.com/celestia-testnet/addrbook.json"

Set up node configuration

celestia-appd config keyring-backend test
sed -i.bak -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0.001utia\"/;" ~/.celestia-app/config/app.toml
EXTERNAL_ADDRESS=$(wget -qO- eth0.me)

sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \"$PERSISTENT_PEERS\"/" $HOME/.celestia-app/config/config.toml

(OPTIONAL) Set up pruning

sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"$pruning_interval\"/" $HOME/.celestia-app/config/app.toml

(OPTIONAL) Set up indexer

#indexer="null"
#sed -i -e "s/^indexer *=.*/indexer = \"$indexer\"/" $HOME/.celestia-app/config/config.toml

(OPTIONAL) Enable/Disable Snapshots

#snapshot_interval=1000
#sed -i.bak -e "s/^snapshot-interval *=.*/snapshot-interval = \"$snapshot_interval\"/" ~/.celestia-app/config/app.toml

If peers do not cling for a long time or you see errors error: wrong Block.Header.AppHash, you need to use State sync or boot from a Snapshot
