# Subscribable In this video, we dive into the "Subscribable" package for AO, a crucial concept in the AO ecosystem. This package lets you subscribe to data and message streams from other processes, enabling event-driven architecture in distributed systems. It's essential for building low-latency, critical infrastructure and can also be used for streaming events on AO. We'll demonstrate how to use it across multiple processes, explain its anti-spam features, and explore how you can potentially monetize your data between processes. {% embed url="" %} {% @github-files/github-code-block %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
