Step 2: Clone the Light Node Repository

git clone https://github.com/Layer-Edge/light-node.git
cd light-node

Step 3: Configure Environment Variables

Set up the required environment variables in your terminal session or add them to a .env file:

nano .env

GRPC_URL=grpc.testnet.layeredge.io:9090
CONTRACT_ADDR=cosmos1ufs3tlq4umljk0qfe8k5ya0x6hpavn897u2cnf9k0en9jr7qarqqt56709
ZK_PROVER_URL=http://127.0.0.1:3001
API_REQUEST_TIMEOUT=100
POINTS_API=light-node.layeredge.io
PRIVATE_KEY='cli-node-private-key'

Replace with your privatkey without 0x

Step 4: Start the Merkle Service

Before running the Light Node, start the Merkle service:

screen -S rsic

cd risc0-merkle-service
cargo build && cargo run

Press CTRL + A + D

Wait until the Merkle service is fully initialized before proceeding.

Step 5: Build and Run the LayerEdge Light Node

screen -S lightnode

go build
./light-node

Press CTRL + A + D

create service file for automation

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

[Unit]
Description=LayerEdge Light Node
After=network.target

[Service]
User=root
WorkingDirectory=/root/light-node
ExecStart=/root/light-node/light-node
Restart=always
RestartSec=5
StandardOutput=journal
StandardError=journal
EnvironmentFile=/root/light-node/.env

[Install]
WantedBy=multi-user.target

sudo systemctl daemon-reload
sudo systemctl enable lightnode.service
sudo systemctl start lightnode.service
sudo systemctl status lightnode.service

check logs

sudo journalctl -fu lightnode.service

Ensure that the Light Node is running independently and correctly connected to the Merkle service.
