# Co-processor Layer Testnet

## Overview

The [Co-processor Layer](/network/core-concepts/architecture/co_processor_layer) is building a community-driven collaborative layer for data developers, aimed at continuously unlocking and enhancing the value of crypto data. Built on the advanced [OP stack](https://docs.optimism.io/stack/getting-started) architecture and integrated with the innovative [Superchain](https://app.optimism.io/superchain/) ecosystem, it ensures efficient, scalable, and secure data processing and management.
