Source Blockchain Set up

If you are reusing your testnet box, you must first remove the old data. Validators from the previous testnet may have usource available to start a new node, use your same wallet:

sudo systemctl stop sourced && \
cd $HOME && \
rm -rf .source && \
rm -rf source && \
rm -rf $(which sourced)

Prerequisites:

Prepare Server

sudo apt update && sudo apt upgrade -y && \
sudo apt install curl tar wget clang pkg-config libssl-dev libleveldb-dev jq build-essential bsdmainutils git make ncdu htop screen unzip bc fail2ban htop -y

Go Make sure to have Golang >=1.19.

go version

Clone Source Chain Repo

git clone https://github.com/Source-Protocol-Cosmos/source.git

Compile sourced Binary

cd ~/source
git fetch
git checkout v3.0.0
make build && make install

Initialize the Source directories and create the local genesis file with the correct chain-id:

sourced init <moniker-name> --chain-id=source-1

Create a local key pair (or add existing key):

sourced keys add <walletName>
    or
sourced keys add <walletName> --recover

Download Genesis File

curl -s  https://raw.githubusercontent.com/Source-Protocol-Cosmos/mainnet/master/source-1/genesis.json > ~/.source/config/genesis.json

Seed nodes to add to config.toml

nano ~/.source/config/config.toml

# Comma separated list of nodes to keep persistent connections to persistent_peers =

Running in production

Note: Consider using Cosmovisor to make your life easier.

Create a systemd file for your Source service:

sudo nano /etc/systemd/system/sourced.service

Copy and paste the following and update :

Description=Source daemon
After=network-online.target

[Service]
User=<YOUR_USERNAME>
ExecStart=/home/<YOUR-USERNAME>/go/bin/sourced start --home /home/<YOUR-USERNAME>/.source
Restart=on-failure
RestartSec=3
LimitNOFILE=4096

[Install]
WantedBy=multi-user.target

This assumes $HOME/.source to be your directory for config and data. Your actual directory locations may vary.

Enable and start the new service:

sudo systemctl enable sourced

sudo systemctl start sourced

Check status:

sourced status

Check logs:

journalctl -u sourced -f
