Run a Free Rinkeby Indexer for The Graph Network

Unlock the Power of Decentralized Data with The Graph

Imagine a world where data from the blockchain is accessible to anyone, anywhere, in a fast, efficient, and reliable manner. Welcome to The Graph, a revolutionary Web3 technology that’s changing the game.

The Mission: Decentralized Data for All

The Graph’s mission is simple yet powerful: to serve data from the blockchain to app developers in a decentralized way. To achieve this, four key roles come into play: Developers, Indexers, Curators, and Delegators.

The Roles That Make It Happen

• Developers: These innovators source data and create GraphQL schemas to make it accessible to others.
• Indexers: They take the GraphQL schema and collect the necessary data to fuel the API, making it live and accessible.
• Curators: These quality controllers inspect subgraphs and use funds to signal their importance, ensuring the best data rises to the top.
• Delegators: By staking their native Graph $GRT tokens, they help secure the network and maintain its integrity.

The Architecture of The Graph

So, how does it all work together? Let’s break it down:

• Our API runs on the indexer software from The Graph, wrapped in a docker-compose package.
• Postgres and InfluxDB are also part of the package, ensuring efficient data storage and querying.
• Our Indexer node talks to an archive node on the Rinkeby test network, providing up-to-date blockchain data.
• Developers can deploy subgraphs to The Graph’s test network, which are then picked up by our Indexer node.

Setting Up Your Indexer Node

Ready to get started? Here’s a step-by-step guide to setting up your Indexer node:

1. Set up the Rinkeby archive node: Use Erigon to scan the blockchain and run 24/7 to keep your datastore up to date.
2. Get an Ethereum Main Network RPC endpoint: Use Infura for a free and lightweight solution.
3. Get your wallet ready: Install MetaMask, generate a 15-word phrase, and import your private key.
4. Pull down the docker-compose package: Input your settings, and you’re ready to go!

Allocate to a Subgraph and Check Your Performance

Now that your Indexer node is running, it’s time to allocate to a subgraph and check your performance:

1. Find a subgraph: Explore The Graph’s subgraph explorer and note the IPFS hash of your chosen subgraph.
2. Allocate 1000 $GRT: Use the Indexer CLI to allocate funds to your chosen subgraph.
3. Check your allocations: Use the graph indexer rules get command to monitor your allocations.

Congratulations! You’re Now a Part of The Graph

You’ve successfully set up your Graph Rinkeby Network Indexer Node! Familiarize yourself with the logs, CLI, and Discord community before moving to Mainnet. Happy indexing!

Remember, The Goal is Efficient Query Serving

All parties involved in The Graph profit from the fast, efficient, and reliable serving of queries on the network. Cost models vary, but the goal remains the same. Read more about it in The Graph’s official documentation.
