SubQuery Network develops open-source data indexing infrastructure for blockchain ecosystems, with its core offering Hermes serving as a permissionless framework for processing and serving blockchain data. The framework enables independent indexers to run distributed nodes that process and store indexed blockchain information. Network participants contribute to a global system that aggregates and serves standardized data to decentralized applications. The organization's Hermes Subnet project integrates with the Bittensor network to create knowledge graphs through distributed AI processing. This subnet coordinates AI miners and validators to perform inference tasks and answer complex queries about blockchain data. The system architecture combines decentralized computing resources with artificial intelligence to optimize data processing workflows. SubQuery's infrastructure supports blockchain developers by providing indexed data access across multiple chains through standardized APIs and query interfaces. The network maintains open-source codebases for indexing frameworks, subnet implementations, and developer tools. SubQuery's architecture enables permissionless participation while ensuring data availability through distributed systems.
