# Background and motivation

The proliferation of blockchain platforms has resulted in a fragmented landscape, with each platform having its own data structures, formats, and query languages. This fragmentation presents several challenges for users and developers seeking to access and analyse on-chain data:

* Limited accessibility and usability: The technical expertise required to interact with various blockchain query languages and APIs creates a barrier for non-technical users who want to access information, hindering the broader adoption of blockchain technology.
* Fragmented data sources: Developers often face the daunting task of integrating data from multiple blockchains and APIs into their applications and services, which can be time-consuming, complex, and prone to errors.

These challenges underscore the need for a unified platform that simplifies the process of querying on-chain data across multiple blockchains, allowing both end-users and developers to easily access and analyse the information they need.
