Welcome to the exciting world of Zeitgeist, a decentralized platform for creating and betting on prediction markets. This blog post will guide you through the process of building and running a Zeitgeist node, whether you want to operate it standalone or integrate it with the Kusama/Polkadot parachain. Let’s dive in!

Understanding Zeitgeist’s Structure

Imagine a bustling marketplace where traders can place their bets on various events, from sports outcomes to election results. Zeitgeist serves as this virtual marketplace, allowing individuals to engage in complex financial contracts on a diverse range of topics using its native currency, ZTG. The platform’s architecture is composed of several modules that each have specialized roles, similar to the different shops in a market:

• authorized: Helps in resolving disputes securely.
• court: A decentralized method for managing conflicts.
• global-disputes: Determines the canonical outcome using locked ZTG tokens.
• market-commons: Contains common market operations.
• neo-swaps: Specializes in combinatorial markets using Logarithmic Market Scoring Rules.
• orderbook: Manages order listings.
• parimutuel: A simple market maker for categorical betting.
• prediction-markets: Core logic for creating and resolving markets.
• swaps: Allows users to create assets pools and swap assets.
• primitives: Custom types and constants used throughout.

Steps to Build a Zeitgeist Node

Let’s break down how to set up your Zeitgeist node. You’ll have two options for running it: standalone or as a parachain.

Building the Standalone Version

For testing on your local machine, the standalone version is your go-to option. Follow these steps:

• Open your terminal.
• Navigate to the top directory of the Zeitgeist project.
• Run the following command:

cargo build --release

• This version will run in the default –dev mode, utilizing the Battery Station testnet.

Building the Parachain Version

If you’re looking to integrate with the Kusama/Polkadot parachain, opt for the parachain version:

• In your terminal, execute:

cargo build --features parachain --release

• This will connect to the Zeitgeist main network by default.

Connecting to Testnet

If your goal is to connect to the Battery Station testnet, follow this command:

cargo run --features parachain --release -- --chain=battery-station

Using Docker for Quick Setup

If you’re familiar with Docker, the process can be even simpler. Zeitgeist offers Docker images for both standalone and parachain nodes. Here’s how you can get started:

• Ensure Docker is installed on your machine.
• To pull the parachain node image, run:

docker pull zeitgeistpm/zeitgeist-node-parachain

• For the standalone version, use:

docker pull zeitgeistpm/zeitgeist-node

• Follow the tutorial available at our documentation site for detailed instructions.

Troubleshooting Your Setup

Here are a few common issues you may encounter while setting up your Zeitgeist node, along with some troubleshooting tips:

• Issue: Connection failures to the network.
  Solution: Check your internet connection and ensure that the expected ports are open.
• Issue: Build failure.
• Solution: Ensure you have the necessary dependencies installed as outlined in the Zeitgeist documentation.
