Query building using GraphQL

The @kadena/graph package is a frontend GraphQL layer built on top of the Kadena blockchain. This tool provides a GraphQL interface to the Kadena blockchain to simplify how you access information about blocks, transactions, accounts, and results. With @kadena/graph, you can stream blockchain events as they happen and guild efficient queries to retrieve blockchain data, including block details, transactions within blocks, outcomes of these transactions, and more. By leveraging a PostgreSQL database backend, fed by the chainweb-data extract, transform, and load (ETL) process, @kadena/graph provides a swift and structured way to access blockchain information.

The primary advantage of using @kadena/graph lies in its speed and efficiency. Traditional methods of retrieving data directly from the blockchain can be cumbersome and slow. @kadena/graph addresses this by offering a faster interface, thanks to its optimized backend. Moreover, it allows users to subscribe to events, offering real-time updates in a structured format. This removes the need for users to perform complex mappings themselves, streamlining the development process for dApp and wallet developers.

The development team behind @kadena/graph is not resting on its laurels. Future releases will focus on performance improvements, particularly through the addition of specific indexes to the underlying database to enhance query performance. The team is also refining the graph schema to accurately reflect the business domain model. A significant upcoming feature is the development of an explorer web application, offering more functionalities than the current explorer. Additionally, plans to include mempool information in transactions are underway, providing users with data even when transaction results are not yet available.

@kadena/graph finds its utility in various scenarios:

While @kadena/graph offers numerous advantages, it is important to note that it is still in the early stages of development. Users may encounter schema changes in future releases, although version control allows users to choose their preferred version. Setting up @kadena/graph for personal hosting requires running a chainweb-node and chainweb-data. However, it is integrated within the devnet environment, facilitating seamless development experiences.

In conclusion, @kadena/graph stands out as a vital tool for anyone looking to interact with the Kadena blockchain more efficiently. Its ongoing development and planned features promise to enhance its utility further, making it an exciting project to watch in the blockchain space.
