Setting Up the Tora Node

Hardware Requirements

Ram	CPU	Disk
8 GB minimum	1 Core	20-40 GB SSD

Step 1: Install Dependencies

Ensure Docker is installed and configured:

sudo apt update -y && sudo apt upgrade -y
for pkg in docker.io docker-doc docker-compose podman-docker containerd runc; do sudo apt-get remove $pkg; done

sudo apt-get update
sudo apt-get install ca-certificates curl gnupg
sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg

echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo $VERSION_CODENAME) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

sudo apt update -y && sudo apt upgrade -y
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

# Verify Docker installation
docker --version

Step 2: Acquire Alchemy API Key

• Sign up at: https://dashboard.alchemy.com/
• Create an Ethereum API and copy both HTTPS and Websockets for Sepolia & Mainnet.

Step 3: Setup the Tora Node

1- Create a directory for Tora

mkdir tora
cd tora

2- Create the .env file

nano .env

Insert the following details into the .env file:

• Replace PRIV_KEY with your Metamask wallet's private key.
• Ensure sufficient ETH is available on both Sepolia and Mainnet for gas fees.
• Provide your Alchemy API URLs for MAINNET_WSS, MAINNET_HTTP, SEPOLIA_WSS, and SEPOLIA_HTTP.
• Set your desired chain confirmation with CONFIRM_CHAINS.

############### Sensitive config ###############

# private key for app transactions

PRIV_KEY=""

############### General config ###############

# provider URLs

MAINNET_WSS=""
MAINNET_HTTP=""
SEPOLIA_WSS=""
SEPOLIA_HTTP=""

# Redis cache time-to-live

REDIS_TTL=86400000 # 1 day

############### App specific config ###############

# chain confirmations

CONFIRM_CHAINS='["sepolia","mainnet"]'
CONFIRM_MODELS='[13]' # OpenLM model
CONFIRM_USE_CROSSCHECK=true
CONFIRM_CC_POLLING_INTERVAL=3000 # 3 sec polling
CONFIRM_CC_BATCH_BLOCKS_COUNT=300
CONFIRM_TASK_TTL=2592000000

• Press CTRL+X, then Y, and ENTER to save and exit.

3- Create the docker-compose.yml file

nano docker-compose.yml

Insert the following code

# ora node docker-compose
version: '3'
services:
  confirm:
    image: oraprotocol/tora:confirm
    container_name: ora-tora
    depends_on:
      - redis
      - openlm
    command: 
      - "--confirm"
    env_file:
      - .env
    environment:
      REDIS_HOST: 'redis'
      REDIS_PORT: 6379
      CONFIRM_MODEL_SERVER_13: 'http://openlm:5000/'
    networks:
      - private_network
  redis:
    image: oraprotocol/redis:latest
    container_name: ora-redis
    restart: always
    networks:
      - private_network
  openlm:
    image: oraprotocol/openlm:latest
    container_name: ora-openlm
    restart: always
    networks:
      - private_network
  diun:
    image: crazymax/diun:latest
    container_name: diun
    command: serve
    volumes:
      - "./data:/data"
      - "/var/run/docker.sock:/var/run/docker.sock"
    environment:
      - "TZ=Asia/Shanghai"
      - "LOG_LEVEL=info"
      - "LOG_JSON=false"
      - "DIUN_WATCH_WORKERS=5"
      - "DIUN_WATCH_JITTER=30"
      - "DIUN_WATCH_SCHEDULE=0 0 * * *"
      - "DIUN_PROVIDERS_DOCKER=true"
      - "DIUN_PROVIDERS_DOCKER_WATCHBYDEFAULT=true"
    restart: always

networks:
  private_network:
    driver: bridge

• Press CTRL+X, then Y, and ENTER to save and exit.

Step 4: Start the Tora Node

docker compose up -d

Step 5: Check logs

cd $HOME && cd tora
docker compose logs -f

• To test that the node is running correctly, request inference from OpenLM on Sepolia at: https://www.ora.io/app/opml/openlm

• Upon successful request, you will observe a log entry from the Tora validator, confirming that it has received and processed the transaction.

• Now you know, whoever use Ora OLM on Sepolia & Mainnet, You will verify a transaction and get these logs, and will receive points as rewards
