Data Streams

Data streams are a fundamental component of the decentralized real-time data layer. They represent the real-time flow of blockchain data provided by publishers and made available for consumption by consumers. Data streams consist of continuous and up-to-date information from blockchains, such as transactional data, smart contract events, token transfers, and other relevant activities.

Key Characteristics

  • Real-Time Updates: Data streams capture and deliver real-time updates from the blockchains, ensuring that consumers have access to the most current information available.
  • Event-Based or Continuous Flow: Data streams can be event-based, triggered by specific actions or changes on the blockchains, or they can be continuous, providing a constant flow of data from the blockchain sources.
  • Structured and Standardized Format: Data streams are formatted and structured in a standardized manner, making them easily consumable by consumers. This includes consistent schemas, data formats, and conventions to enable seamless integration and analysis.
  • Granularity and Scope: Data streams can be tailored to specific granularities and scopes, allowing consumers to access data at various levels of detail. This could range from high-level summaries to fine-grained transactional data.


  • Real-Time Insights: Data streams provide consumers with access to real-time blockchain data, enabling timely and informed decision-making, analysis, and monitoring.

  • Continuous Availability: Data streams ensure a continuous and uninterrupted flow of data, enabling consumers to stay up to date with the latest blockchain activities.

  • Easy Integration: Data streams are structured and standardized, making it easier for consumers to integrate the data into their own systems, applications, or analytical workflows without significant data transformation efforts.

  • Flexibility and Scalability: Data streams offer flexibility in terms of granularity and scope, allowing consumers to choose the level of detail that best suits their specific use cases. They can scale their consumption based on their needs and handle varying volumes of data.

In summary, data streams are the real-time flow of blockchain data provided by publishers and made available for consumption by consumers. They offer real-time updates, structured formats, and scalability, enabling consumers to access, analyze, and utilize the latest blockchain data to drive their business insights and decision-making processes.
