Subsquid (SQD) is an innovative decentralized data lake and query engine designed to empower developers with high-performance, permissionless access to blockchain data. Launched in 2021, Subsquid aims to replace rigid, monolithic indexing frameworks and centralized infrastructure with a modular, scalable, and developer-friendly alternative. The network is rooted in Web3 principles, emphasizing decentralization, openness, and neutrality.

What is Subsquid?

Subsquid is a next-generation blockchain data infrastructure built to meet the demands of modern Web3 development. It serves as a powerful tool for developers in need of efficient blockchain indexing, decentralized application (dApp) development, and data analytics. Its decentralized architecture enables the granular selection and streaming of blockchain data to lightweight clients—making it especially efficient for data-heavy applications in DeFi, GameFi, supply chains, and AI.

The project quickly gained traction in the Substrate ecosystem and has since expanded to support Ethereum Virtual Machine (EVM)-compatible chains. With over 60,000 indexers deployed by 17,000 developers, Subsquid has become a popular solution for scalable, reliable, and cost-effective blockchain data services.

Key Technology: Modular Architecture & ZK Proofs

Subsquid’s infrastructure is powered by a modular architecture and fortified by zero-knowledge (ZK) proofs. This dual approach ensures scalability, efficiency, and robust security:

• Modular Design: Enables zero-downtime migrations and tailored deployments, enhancing flexibility for developers.
• ZK Proofs: Protect data integrity and privacy without exposing the underlying data, a critical component for maintaining trust in a decentralized environment.
• Decentralized RPC Endpoints: Improve performance and reduce dependency on centralized providers.

This infrastructure not only streamlines blockchain data interaction but also ensures resistance to censorship, central points of failure, and high operational costs associated with legacy systems.

Real-World Use Cases

Subsquid’s versatility has led to its adoption across a wide range of Web3 sectors:

• DeFi: Powers secure, reliable data feeds for lending, trading, and yield farming platforms.
• GameFi: Enables real-time tracking and verification of in-game assets.
• Supply Chain: Provides traceability and transparency across complex logistics networks.
• AI & Analytics: Offers high-throughput, tamper-resistant data for machine learning models and real-time dashboards.

Notable integrations include projects like PancakeSwap, Hydration, and ChainSafe, while collaborations with giants like Google Cloud further cement Subsquid’s standing in the Web3 ecosystem.

Key Milestones

• 2021: Subsquid is launched as a response to centralized and inefficient data indexing frameworks.
• 2022: Gains dominance in the Substrate ecosystem and debuts its public testnet.
• 2023: Launches its mainnet on Arbitrum, a Layer 2 scaling solution for Ethereum.
• 2024: Introduces modular indexing via light indexers and SQL queries, enhancing developer flexibility.

Leadership and Vision

The Subsquid network is led by co-founders Dmitry Zhelezov (CEO) and Marcel Fohrmann, both of whom bring extensive expertise in blockchain and decentralized technologies. Their mission is to create a permissionless, high-performance gateway to Web3 data, catalyzing innovation across the crypto ecosystem.
