Coprocessor: Indexers for Data Rich Access



Phala Network's collaborations with The Graph, Subsquid, and Airstack revolutionize data accessibility for web3, enabling developers to build sophisticated, privacy-centric dApps. These partnerships provide tools for seamless data querying, high-performance indexing, and cross-chain data access, fostering a richer dApp ecosystem with improved privacy and user experience. A leap forward for developers aiming to innovate in the secure and interconnected web3 space.

Introduction to the World of Indexers

In the expansive and ever-evolving landscape of web3, data accessibility stands as a critical pillar, enabling decentralized applications (dApps) to harness the full potential of blockchain technology. Indexers play a pivotal role in this ecosystem, acting as the librarians of the blockchain world. They meticulously organize, categorize, and make blockchain data easily searchable, transforming the raw, unstructured data from the blockchain into a neatly organized database that can be quickly queried for specific information.

Understanding Indexers Through a Simple Analogy

Imagine a vast, sprawling city with an intricate network of roads, vehicles, and traffic signals—a vibrant hub of movement and activity. Each vehicle's journey through this network mirrors individual transactions on the blockchain, with their routes and interactions forming a complex web of data. Now, envision a sophisticated traffic management system equipped with the latest technology, capable of monitoring, analyzing, and optimizing this flow of vehicles to ensure smooth, efficient travel.

This system represents an indexer: a powerful tool that distills chaos into order, enabling quick, efficient access to precise information within the vast data landscape of the blockchain.

A blockchain indexer simplifies dApp development by organizing on-chain data for easy access and retrieval, enabling developers to focus on building their applications rather than managing data complexities. It offers a custom GraphQL endpoint for efficient data presentation, supports multi-chain data aggregation, and provides a managed service for reliable access to real-time or historical data. Indexers like Envio, The Graph, Subsquid and GraphQL enhance productivity, reduce development time, and improve the end-user experience by offering speed-optimized solutions that handle the intricacies of blockchain data management, making them indispensable tools for developers in the Web3 space.

Popular Indexers for Web3

There are various blockchain indexers available for developers to choose from, each specializing in supporting different use cases such as infrastructure, DeFi, NFTs, and more. Their support also varies across different blockchains.

Let's briefly touch on a few of these tools:

  • The Graph: A decentralized protocol for querying and indexing data from blockchains.
  • Zettablock: Real-time web3 data infrastructure for indexing and analytics. Build your own low-latency APIs for your app.
  • Transpose: Real-time access to high-level blockchain data via REST and SQL API.
  • Subsquid: A powerful decentralized indexing protocol optimized for dapps and big data analytics.
  • Goldsky: Powering apps with real-time blockchain data and subgraphs without managing complex infrastructure.
