Fusion - Define processing workflows


Closed Beta

This feature is in closed beta and only available for our enterprise customers.

Access our app at app.goldsky.com and fill in the request form for this Add-on, and our team will get back to to help you get set up.

At the core, Goldsky is powered by an extreme low-latency real-time streaming engine called Fusion. With Transforms, you get direct access to that engine to execute SQL transformations.

Data transformations are a powerful way to convert raw blockchain data into data insights that are valuable to your project.

You write transformations in a familiar SQL-like syntax. We are working on documenting this in more detail, please contact us if you are interested in writing data transformations to process your blockchain data in real-time.

Transformations update in real-time

As data is added to a blockchain, each transformation is kept up-to-date with the latest block.

This allows you to use your streams for transactional use cases within your applications.

Example use cases

Below are a few examples of what is possible with Goldsky’s data transformations. Note though, this is a small set of examples, the (gold)sky is the limit 🙂.

  • Aggregate data in real-time, without having to think about data freshness and query intervals
  • Apply complex filters without any query time overhead
  • Detect fraudulent or corrupt data as soon as it happens
  • Create streams for monitoring purposes
