# ARC Implementation and Future Outlook

{% file src="/files/zxAL0Uy6v8ojNaDAqE6r" %}

[**ARC**](https://github.com/bitcoin-sv/arc) serves as a proto-overlay service, functioning as a **transaction propagation and Merkle path delivery service**. It operates as a generic overlay service that **does not filter out any transactions**, handling any valid transaction it receives. ARC ensures that a default transaction broadcast endpoint is readily accessible to applications in the absence of a specific overlay tailored to their needs.

As a **reference implementation for overlay services**, ARC demonstrates best practices and provides a foundational framework upon which developers can build more specialized overlays.
