Install and Configure Full Node

Enable ports on Firewall

Set up these ports on your firewall:

sudo ufw allow 26656/tcp

Check firewall status to see if the port has been enabled

sudo ufw status

Install Sentinel Hub

To install Sentinel Hub, please download the latest version from the repository and proceed by executing the following commands:

git clone https://github.com/sentinel-official/hub.git "${HOME}/sentinelhub"
cd "${HOME}/sentinelhub"
git checkout vX.X.X
make install

# For Ubuntu installation
sudo ln -s "${GOBIN}/sentinelhub" /usr/bin/sentinelhub

# For manual installation
sudo ln -s "${GOBIN}/sentinelhub" /usr/local/bin/sentinelhub

Configure Sentinel Hub

Genesis File

Let's initialize the Sentinel Hub using the Genesis file, a JSON file which defines the initial state of Sentinel blockchain. The state defined in the genesis file contains all the necessary information, like initial coin allocation, genesis time, default parameters, and more

sentinelhub init --chain-id sentinelhub-2 "Your Validator Name"
curl -fsLS -o "${HOME}/genesis.zip" "https://raw.githubusercontent.com/sentinel-official/networks/main/sentinelhub-2/genesis.zip"
unzip -d "${HOME}/.sentinelhub/config/" "${HOME}/genesis.zip"
rm "${HOME}/genesis.zip"

You will be asked to replace the genesis file, type [A]ll

In case you need a mirror because the official hosting site does not work, use this:

wget -O genesis.json https://snapshots.polkachu.com/genesis/sentinel/genesis.json --inet4-only
mv genesis.json ~/.sentinelhub/config

Edit the Node configuration file

Open the config.toml file

sudo nano ${HOME}/.sentinelhub/config/config.toml

Set seeds and peers separated by comma.

Seeds: are initial entry points for new nodes joining the network and are typically used during the bootstrap phase. In this phase, a new node connects to them to obtain information about the network's topology and to discover other nodes to connect to. The seeds you see below are taken from here
Peers*: are usually nodes that a given node wants to maintain a reliable and consistent connection with, often because they have specific roles in the network or are deemed important for communication. The below peers were taken from Polkachu Validator

${HOME}/.sentinelhub/config/config.toml
[p2p]
seeds = ""
persistent_peers = ""

Add the followings:
